1.2 Motivation

The motivation for this project is based on the growing concern about the degradation of marine ecosystems and the decline of natural reef habitats. Coral reefs and other complex seabed structures provide important habitats for many marine species, including fish, invertebrates, and algae. However, many of these ecosystems are currently under pressure due to factors such as climate change, pollution, overfishing, and habitat destruction.

Artificial reefs have been proposed as one possible approach to support marine biodiversity and help restore degraded habitats. By creating structures that mimic the complexity of natural reef environments, artificial reefs may provide shelter, feeding areas, and breeding grounds for marine organisms. Understanding how different materials and structural designs influence these habitats is therefore an important topic in marine environmental research.

1.3 Product

The idea of this project is to create a marine habitat for underwater enviroments, in order to promote the live of the diferent species that habit the the seabed of the coastal plate. Since this is the environment of many endangered species and its a global problem, our goal is to improve this situation while monitoring the characteristics that may affect this danger that threat the sea life.

For this project, the mainthought consists of a structure made to sit in the sea floor, with the purpose of being colonized by many aquatic species to use it as a shelter where to follow their natural way of living. This intends to recreate a natural environment, and ir order to get that it is needed to review the most suitable material, as well as the best designs for the viability of the project.

To fulfill the task of monitoring the conditions, it is necessary researching about the sensors that can take that job properly, and an organizational model that allow to get the needed information, without disturbing the environment and complying with all regulations.

Finally, the final target it is to create social awareness, so more people can learn about the current situation going underwater. With all the information it can be recolected, the best chance is not only with the science or research, it is to concern people about the biggest resource on earth, the sea.

1.4 Problem

The basis for develop this idea starts on a global view of a huge environmental problem, the sea is dying. The causes of this problem are multiple; the global warming is raising not only the level of the oceans but the temperature of them. This is alterating the conditions of most of the underwater eco-systems, and this evolves in multiple species having to migrate from their original enviroments to new ones.

Another big problem is the massive fishing made by human hands. All around the wolrd, fishing is a daily practice, and is strongly regulated by governments and various institutions, it has affected the natural cycle of the sea-life. Now it has become a huge problem, since a lot of fish species are being depleted and others are being affected by the food chain, every creature in the sea is in danger.

The third big issue going on, concerns the levels of oxygen in the sea. With most of the fauna being altered, the flora is also damaged, the Great Barrier Reef and other coral reefs responsible of producing between 60 % and 80 % of the oxygen that is breathed, are rapidly dying, already more than 50 % of it has died in the last decades, so a global problem is incoming, and it is our job to do the possible to solve it.

1.5 Objectives

This project focuses on developing a sustainable and technically feasible solution to remediate the loss of seafloor habitats. The goal is to counteract current environmental decline by providing artificial structures that serve as refugia for marine life, thereby enhancing biodiversity and population recovery.

More specifically, the objectives are:

  1. Create an appropiate structure for life to happen: This is one of the most challenging objectives, as creating a marine habitat that marine life accepts and colonizes appropriately will undoubtedly be a lengthy process. Understanding how life underwater functions—which shapes, textures, materials, and processes are best accepted by different species—is as complex as life itself. Therefore, constant adaptation will be the core mindset throughout the entire process.
  2. Ensure the sustainability without life disturbance: Accomplishing everything mentioned above sounds great, but the critical factor for life to thrive in a way that mimics natural flow is to minimize human or robotic interactions and disturbances in the environment. Therefore, ensuring total naturalness will also be of vital importance.
  3. Recolect information from this habitats to improve them: Although the project generates a clear positive impact on society, it must provide a way to measure that benefit. This will be achieved through data collected by sensors that will be implemented according to specific needs. This information will also be used to improve and pave the way for better models of the project.
  4. Create social awareness about the situation and the urge for a solution: Making people realize the scale of the problem the society is facing is a major step forward; in this way, the world will no longer be fighting a constant uphill battle. The goal is to encourage everyone to do their part in improving the state of the sea so that, in the future, these artificial habitats are no longer necessary. However, all of this begins by alerting the public and making them aware of the severe risks involved.

1.6 Requirements

This section defines the main requirements of the system. The requirements are divided into functional and non-functional categories. Functional requirements describe what the system does, while non-functional requirements define the conditions needed for reliable operation in a marine environment.

1.6.1 Functional Requirements

The system must collect environmental data at predefined time intervals. The measured parameters include water temperature, pressure (depth), pH, and conductivity.

The collected data must be stored locally using a data storage unit such as a Secure Digital (SD) card, allowing continuous operation without relying on external communication infrastructure.

Energy consumption must be minimized to extend operational lifetime. This is achieved through low-power operation, where the system remains active only for short periods during measurement cycles.

The system must perform measurements periodically, typically once per hour. During each cycle, the system remains active only for the time required to stabilize sensor readings and store the data.

The physical structure must include cavities and textured surfaces to support the attachment and growth of marine organisms.

1.6.2 Non-Functional Requirements

In addition to functional capabilities, the system must satisfy several non-functional requirements to ensure safe and reliable operation in marine environments. Since the structure is deployed underwater and interacts directly with marine ecosystems, material selection and structural design are critical.

To avoid failures observed in previous projects such as Osborne Reef, the structure must be composed of pH-neutral, non-toxic materials that do not release harmful substances into the marine environment [1].

The main structural material is eco-concrete, selected due to its improved compatibility with marine life compared to traditional concrete [2].

Basalt fiber is used as a reinforcement material to improve structural durability and resistance to mechanical stress [3].

The structure must be designed to remain stable under currents and wave conditions without displacement.

All electronic components, including sensors, batteries, and storage units, must be enclosed in a waterproof housing with at least IP68 protection to prevent water ingress and ensure long-term operation underwater [4].

Condensation inside the enclosure must be controlled using moisture-absorbing materials. A pressure relief valve must also be included to regulate internal pressure.

2.1 Introduction

This chapter establishes the technical and scientific foundation for the MARIS HABITATS project by situating it within the broader landscape of underwater monitoring and artificial reef design. While the field of marine biology has long utilized static structures for habitat restoration, the integration of real-time Internet of Things (IoT) capabilities remains a significant hurdle due to high costs and technical complexity.

By analyzing essential water quality parameters —such as pH, temperature, and turbidity— through the embedded systems required to track them, the specific technical gaps that the modular approach aims to fill can be indentified. This review serves not only as a state-of-the-art summary but as a justification for a cost-effective, sensor-integrated platform that moves beyond traditional, “passive” artificial reefs.

2.2 Concepts

Artificial marine habitats can be designed in several ways to help restore marine ecosystems and support endangered fish species. One approach is the use of 3D-printed reef corals, which can be made from materials such as ceramic, limestone, or eco-concrete. These materials are durable and suitable for marine environments. Examples of projects using this approach include the Reef Design Lab in Australia and SECORE coral restoration projects, both of which focus on rebuilding reef structures that allow coral and marine organisms to grow again [5], [6].

Another commonly used solution is reef balls. These are concrete dome structures with holes that mimic natural reef caves. Because of their simple design they are easy to mass produce and very stable when placed on the seabed. The holes and cavities provide immediate shelter for fish and other marine animals, allowing the structures to quickly function as protective habitats [7], [8].

A different method is the creation of Bio-Rock or electric reefs. These reefs consist of metal structures through which a small electrical current is passed. This current causes minerals from seawater to deposit onto the structure, gradually forming a limestone-like coating. This process helps corals grow much faster than under normal conditions, and fish rapidly colonize these artificial reefs. This technique is known as Bio-Rock technology [9].

Artificial habitats can also be designed as modular “fish cities”. These structures include holes of different sizes so that multiple fish species can use them for shelter. Vertical elements are often incorporated to mimic natural reef cliffs, and the modules can be interconnected to create more complex ecosystems that support a greater diversity of marine life [10].

Another concept is the development of living seawalls. These are harbor walls or seawalls designed with textured panels and cavities so that marine organisms can attach to them and live on them. Instead of smooth concrete surfaces that support little life, these modified structures create habitats for algae, small invertebrates, and fish [11].

Several endangered fish species can benefit from these types of artificial habitats, including the Humphead wrasse, Nassau grouper, Atlantic Goliath Grouper, Smalltooth Sawfish, and the European eel. Although many of these species grow quite large, the habitats are especially important for juvenile fish. Young fish can use the structures as shelter and breeding areas, increasing their chances of survival. When more juvenile fish survive, adult populations can recover and thrive. Larger predators may also benefit by hunting around these habitats.

In habitat design, the shape of the structure is often more important than the material used. It is important to include many holes and cavities in different sizes so that different fish species can find suitable shelter. Vertical structures are also important because they mimic natural reef cliffs. In addition, rough surface textures help corals and algae attach and grow on the structures. Finally, ensuring good water flow around the habitat is essential, as it brings nutrients and oxygen that support marine life.

2.3 Comparative Analysis

The selected solutions are evaluated based on criteria such as monitoring capability, structural complexity, sustainability, durability, and ecological performance.

The comparison presented in Table 2 is based on publicly available information from product descriptions and related documentation. In cases where information was not clearly specified, this is indicated accordingly.

As shown in Table 2, existing solutions mainly focus on structural design and ecological enhancement. However, based on the available information, these solutions generally do not include integrated monitoring systems or continuous data collection capabilities. In contrast, the proposed Maris Habitats system combines habitat construction with environmental monitoring, enabling continuous data collection and supporting data-driven decision-making.

2.4 Companies

This section presents existing solutions related to artificial reef systems and marine infrastructure. The purpose of this analysis is to understand how current solutions are designed and what features they provide. It also helps to identify limitations that can be considered in the development of the proposed system.

MEITEC

MEITEC is a company that develops artificial reef structures for marine environments [12]. These structures are designed to be placed on the seabed and are intended to support marine ecosystems.

The structures are typically made from concrete materials, which provide mechanical strength and allow the system to remain stable under ocean conditions. This type of structure is commonly used in artificial reef applications because it can withstand external forces such as currents and waves.

The design of these structures provides physical spaces where marine organisms can attach, hide, and interact. These features can contribute to the formation of habitats over time.

In some cases, additional devices such as flow meters or temperature sensors may be used (see Figure 1). These devices can provide basic environmental information. However, based on the available information, there is no clear indication that these systems include fully integrated or continuous environmental monitoring capabilities.

This suggests that the main focus of the system is on structural design and habitat creation, while the integration of monitoring functions is limited.

Figure 1: Installation of a flow meter and water temperature sensor in an underwater environment [13]

ECOncrete

ECOncrete develops concrete solutions that are designed to improve the interaction between marine infrastructure and the surrounding ecosystem [14].

The material is modified in terms of surface texture and composition in order to support the attachment of marine organisms. These modifications aim to create conditions that are more suitable for biological growth compared to traditional concrete.

Such solutions are applied in coastal and marine infrastructure, including structures such as seawalls and shoreline protection systems. In these applications, the structures maintain their engineering function while also providing ecological benefits.

Marine organisms can attach and grow on the surface of these structures over time, as shown in Figure 2.

However, these systems mainly act as passive structures. They are designed to support marine life, but they do not actively collect environmental data. Based on the available descriptions, there is no clear indication of integrated sensing or continuous monitoring within the structure.

Figure 2: Eco-concrete coastal structure showing marine organism growth on its surface in a biodiversity enhancement project [15]

IntelliReefs

IntelliReefs is a project that focuses on developing artificial reef systems using alternative design approaches [16].

The project explores different structural configurations and materials in order to improve ecological performance and reduce environmental impact compared to traditional reef systems.

The design of the structures aims to provide suitable habitats for marine organisms by creating complex geometries and sheltered spaces, as shown in Figure 3.

These modular structures form interconnected reef systems that can support diverse marine habitats.

However, based on the available information, the system mainly focuses on structural and ecological aspects. There is no clear indication of integrated sensing technologies or continuous environmental monitoring capabilities.

This suggests that, while IntelliReefs contributes to improved reef design, the integration of data collection and monitoring functions remains limited.

2.5 Materials

For this project involving a marine habitat at a maximum depth of 50 m off the Portuguese coast, the materials must withstand a pressure of approximately 5 bar while fostering biological growth and protecting sensitive sensors. To ensure the highest level of efficiency and environmental compatibility, various materials used in international restoration efforts has been analyzed.

The selection of materials and the structural design of artificial habitats are fundamental to ensuring both environmental compatibility and long-term viability. For this project, concrete has been identified as the primary material due to its exceptional durability and its proven track record in underwater construction. Its capacity to provide structural integrity against significant environmental stressors—such as salinity, strong currents, and wave action—makes it the industry standard for creating resilient marine foundations. While the chemical properties of concrete, particularly its initial pH levels, have historically been a point of debate, recent research has shifted the focus toward a more nuanced understanding of its behavior in open marine environments [18].

Studies indicate that the high alkalinity of newly submerged concrete (typically between 12–14) is rapidly diluted by seawater, resulting in no significant long-term detriment to coral growth or benthic colonization [19]. This suggests that ecological success depends less on extended curing periods or pH-neutral mixtures and more on the physical attributes of the habitat. Consequently, the following sections will detail how this project prioritizes structural complexity, substrate durability, and hydrodynamic stability [20]. By optimizing the weight-to-complexity ratio and ensuring low water absorption, it can be guaranteed that these structures remain stationary during extreme weather events while providing the necessary niches for biodiversity to thrive [21].

Based on the research and articles reviewed, the following subsection evaluates different material options—ranging from traditional foundations to innovative biocompatible substrates—from which the selection for the most suitable components will be done for this specific implementation.

2.5.1. Structural Materials

A. Bacterial (Self-healing) High-Strength Concrete (HSC) This material incorporates bacterial spores, specifically Bacillus sphaericus (strain ATCC 14577), which remain dormant until a crack occurs. Water ingress activates the bacteria, which then precipitate calcium carbonate to seal the crack [22].

  • Pros: Achieves 96 % recovery in water tightness within 56 days of seawater immersion [23]. It maintains structural integrity above 100 MPa, which is more than sufficient for the pressure at 50 m. It significantly reduces rebar corrosion by sealing entry points for chloride ions [24].
  • Cons: Higher complexity in mixing and requires specific nutrients like calcium lactate and urea [25].
  • Price: Estimated at 180 €/m3 – 260 €/m3.

B. Basalt Fiber-Reinforced Polymer (BFRP) Basalt fibers, derived from natural volcanic rock, are used to reinforce concrete or as standalone composite laminates [26].

  • Pros: Naturally non-corrosive and chemically stable in aggressive saline environments [27]. Vacuum infusion manufacturing can produce laminates with flexural strength up to 400 MPa [28]. It provides a more resilient, damage-tolerant failure mode compared to the brittle collapse of traditional reinforced concrete [29].
  • Cons: Slightly lower peak flexural strength compared to glass fibers, although superior in long-term durability and environmental footprint [30].
  • Price: Estimated at 160 €/m3 – 220 €/m3 .

C. Geopolymer Gel Concrete A cement-free binder using materials like fly ash and metakaolin modified with nano-silica (SiO2) [31].

  • Pros: Significantly lower CO2 footprint than Portland cement [32]. It shows superior resistance to chloride and sulfate attack in “wet-thermal” marine environments [33].
  • Cons: Higher production costs currently limit wide adoption [34].
  • Price: Estimated at 150 €/m3 – 200 €/m3.

D. ECOncrete® / Sulfoaluminate Cement (SAC) A proprietary concrete mix designed to reduce surface alkalinity to a neutral pH [35].

  • Pros: Surface pH of 9–10 (closer to seawater's 8) promotes the settlement of “ecosystem engineers” like oysters, serpulid worms, and coralline algae. These organisms provide bioprotection, adding a calcified layer that strengthens the structure and limits oxygen/chloride penetration [36].
  • Cons: Requires specialized design to ensure the lower pH doesn't compromise the protection of internal steel if used.
  • Price: Estimated at 140 €/m3 – 180 €/m3.

E. Recycled Glass (Partial Aggregate Replacement) Crushed waste glass used to replace up to 30 % of fine aggregates in the concrete mix [37].

  • Pros: Improves chemical resistance and reduces water absorption [38]. It offers an eco-friendly way to utilize waste while maintaining sufficient compressive strength for marine applications [39].
  • Cons: Replacing more than 30 % of aggregate leads to a significant reduction in compressive strength [40].
  • Price: Estimated at 90 €/m3 – 140 €/m3.

F. Biorock (Mineral Accretion) Uses low-voltage DC electricity to precipitate minerals (limestone) directly from seawater onto an iron frame.

  • Pros: Accelerates biological growth by 400 % and allows the structure to self-repair after impacts.
  • Cons: Requires constant power from your buoy; if the power is interrupted, the iron frame corrodes rapidly.
  • Price: Base infrastructure 120 €/m3 – 160 €/m3 (excluding electrical components).
2.5.1.1 Summary Table

The previous subsection regarding the materials evaluated for the project, is sumarized in Table 3.

Table 3: Summary table for materials evaluated
Material Primary Requisite Met Pros Cons Estimated Price / m3
Bacterial HSC Longevity/Pressure Autonomous repair; 96 % watertight High complexity 180–260 €
Basalt Reinforcement Corrosion Resistance Non-corrosive; volcanic origin Lower flexural peak 160–220 €
ECOncrete® Sea-life Friendly Neutral pH; bioprotection Specific mix needs 140–180 €
Recycled Glass Sustainability Increased chemical resistance Strength loss > 30% 90–140 €
Biorock Life Promotion 4:1 growth; self-repairing Power dependent 120–160 €
2.5.1.2 Materials for Prototype vs. Final

Here we have another issue, since we have to present a prototype where it has to be functional and pass some test previously mentioned, we need to select a material with similar characteristics to the actual model, in order to be as close as possible. But also that is easy to get and handle since we are gonna be the ones using it.

TO BE CHECKED WHEN THE PROTOTYPE HAS TO BE DONE

  • Option 1 : Basalt fabric-reinforced is attached to abandoned concrete or industrial waste. We need to check the pH level is neutral this process.
    • pros It is similar to the actual product and cuts down on costs.
    • cons It is impossible to modify the model design and there is no marketing advantage because it is not different from existing business.
  • Option 2 : Polymer-clay is just shaped into the model we want and baked in the oven.
    • pros It is possible to be mini version of the actual model in any shape and cuts down on costs.
    • cons There are size limitations depending on the oven and it is different from the model of actual project so not sure if it will approve.
2.5.2 Sensor placements

Designing a successful marine habitat involves a delicate technical paradox. On one hand, the project’s primary objective is to encourage biological colonization and the growth of marine life; on the other, the integrated sensors require direct, unobstructed contact with seawater to maintain accuracy. This necessity creates a significant challenge, as the very “bio-friendly” environment the team aims to foster can lead to marine biofouling on sensitive equipment, which critically compromises data reliability and sensor sensitivity [41].

To resolve this conflict, our strategy focuses on three integrated design pillars. First, a carefully selection of housing materials that support structural life while shielding internal components must be done. Second, evaluating specialized anti-fouling coatings that can prevent accumulation on sensor windows without leaching harmful chemicals into the surrounding habitat. Finally, the spatial distribution of the sensors must be strategically planned to allow for clear measurements while minimizing their exposure to rapid biological growth. This balanced approach ensures that our ecological goals do not come at the expense of long-term monitoring precision.

2.5.2.1 Materials for Housing

Titanium alloy (TC4) or 316 L stainless steel are recommended for pressure resistance and durability [42]. For a 200 m depth, Titanium is preferred for long-term corrosion resistance [43].

2.5.2.2 Antifouling Coatings
  • PDMS (Polydimethylsiloxane): A non-toxic, “fouling-release” coating that reduces the adhesion of algae and barnacles [44].
  • CPT (Camptothecin)-based Paint: A natural compound that has shown virtually no macrofouling after nine months of immersion [45].
  • SLIPS (Slippery Liquid-Infused Porous Surfaces): These provide exceptional resistance to organism attachment even in stagnant water [46].
2.5.3 Biologic and geographical analysis

Fish structure

Fish populations are generally associated with habitats that exhibit high structural complexity and spatial heterogeneity [47]. Research suggests that complex environments provide essential ecological resources necessary for survival, including food availability, shelter from predators, and suitable areas for reproduction. Structural features such as crevices, cavities, and irregular surfaces may create microhabitats that support a greater diversity of marine organisms and increase the overall ecological value of reef systems.

Artificial and natural reefs typically contain irregularities and indentations that form small shelters or “nooks”, which can serve as refuge areas for fish and other marine organisms. These structural features are believed to reduce predation risk and provide protected spaces where fish can rest or reproduce.

Studies also indicate that fish communities tend to perform better in connected habitat mosaics rather than isolated structures [48]. Networks of habitats may facilitate movement, feeding opportunities, and ecological interactions between species, which can contribute to more stable and diverse marine ecosystems.

Location

The location of artificial reefs plays a key role in determining their effectiveness. The chosen site should encourage marine life to settle while avoiding interference with human activities such as shipping routes or commercial fishing areas. Water depth is another important consideration. Reefs placed too deep may not receive enough sunlight to support the growth of marine plants like algae, whereas reefs that are too shallow can be more vulnerable to damage from storms or human activity [49].
Most of the artificial reef projects are placed at the depth of 30 M but it all depends on which species and what type of marine life are the reefs intended for (see Table ##REF:tab_label1##).

2.6 Summary

The comparison indicates that current artificial reef solutions primarily focus on structural and ecological aspects. Solutions such as ECOncrete and IntelliReefs demonstrate strong performance in sustainability and ecological enhancement, while MEITEC emphasizes structural stability and durability.

However, none of the analyzed solutions incorporate real-time monitoring or data transmission capabilities. This represents a significant limitation, as the effectiveness of marine restoration projects cannot be easily measured or optimized without continuous environmental data.

In addition, while modularity and structural complexity vary among solutions, scalability and long-term adaptability remain key challenges in existing systems.

Based on this analysis, it was observed that existing solutions provide valuable approaches to habitat design and ecological enhancement, but lack integration with data-driven technologies. These observations served as both a limitation and a source of inspiration for the proposed project.

The design direction was therefore developed to combine the strengths of current solutions—such as sustainability, structural performance, and ecological support—while addressing their limitations through the integration of real-time monitoring and data collection capabilities.

3.1 Introduction

Managing a project that intersects marine ecology, hardware engineering, and software development requires a framework that balances rigid constraints with creative flexibility. This chapter details the management strategy employed by the group, organized across key knowledge areas including scope, risk, and procurement.

Due to the unpredictable nature of environmental hardware testing, the team adopted an Agile (Scrum-inspired) methodology. This iterative approach was essential for managing the project. By prioritizing continuous feedback loops and adaptive planning, the team was able to pivot in response to technical challenges without compromising the project's primary milestones or budgetary limits.

3.1 Scope

The scope of this project is the design and development of a functional prototype of a smart marine habitat intended to support seafloor biodiversity and enable environmental monitoring in underwater conditions. The project focuses on creating a concept that combines an artificial habitat structure with a basic sensor system, while taking into account sustainability, durability, and ecological compatibility.

From a product perspective, the project includes the development of a modular underwater habitat structure designed to provide shelter, attachment surfaces, and spatial complexity for marine organisms. In addition, the product includes an integrated monitoring concept based on selected sensors capable of collecting environmental data relevant to the surrounding habitat, such as temperature, pH, turbidity, or depth, depending on technical feasibility and component availability. The solution also includes a basic embedded electronics system for sensor integration, power management, and data handling, as well as a conceptual approach for transmitting or presenting the collected data. The overall product is intended to demonstrate how habitat restoration and environmental monitoring can be combined into a sustainable solution.

From a project perspective, the scope includes the research and analysis required to understand the environmental problem, existing artificial reef solutions, suitable structural materials, and underwater sensor technologies. It also includes the definition of requirements, concept development, design selection, structural modelling, component selection, and prototype integration. The project covers the testing and validation of the prototype under limited and controlled conditions, together with the assessment of market, sustainability, ethical, and project management aspects. The preparation of all academic deliverables, including the report, presentation, poster, flyer, and supporting documentation, is also part of the project scope.

The main outcome of the project is a functional prototype that demonstrates the technical feasibility and conceptual value of a smart artificial marine habitat. The prototype is intended to serve as a foundation for future development, testing, and scaling in real-world marine applications.

The Work Breakdown Structure (WBS) presented in the figures illustrates how the MARIS HABITATS system is divided into its main components and subsystems. The diagram provides an overview of the product architecture, showing how the habitat structure, sensor system, energy and communication, deployment, and maintenance elements are organized.

Each main component is further broken down into smaller elements, representing the key functionalities required for the system to operate. This visual representation helps clarify the scope of the project by identifying all relevant parts of the system and their relationships.

3.3 Cost

When calculating the cost of the project, there are two key factors that need to be taken into consideration: employee salaries and the cost of materials and components.

The average salary for a junior engineer in Portugal is €1,500 per month, and the project duration is five months.

Therefore, the total salary cost is calculated as: 6 employees × 1500 € × 5 months = 45000 €

Describe your project budget and its key components. Explain how your budget was managed throughout the project. Document the planned vs. effective costs of your project.

3.4 Quality

Quality in this project is ensured by defining clear quality metrics for both the system and the documentation, together with acceptable thresholds and review procedures.

For the product, key quality metrics include system functionality, structural stability, and sensor reliability. The system is considered acceptable when all core functions operate as intended, the structure remains stable under expected conditions, and the sensors provide consistent and reasonable data. These aspects are reviewed through testing in controlled environments and validation of system performance.

For the documentation, quality is measured in terms of clarity, structure, consistency, and completeness. The report must clearly explain the project, follow a logical structure, and include all required sections. The acceptable threshold is that the documentation is understandable, coherent, and meets the academic guidelines provided. This is reviewed through internal checks within the team and feedback from supervisors.

Regular reviews during sprint meetings are used to monitor progress and identify issues early. Corrections are made continuously to ensure that both the system and the documentation meet the expected quality standards.

People & Stakeholder Management

Human factors represent a significant source of uncertainty in project development, as team members may exhibit varying levels of engagement, performance, and responsibility. For this reason, it is essential to establish clear roles and responsibilities within the team, ensuring that each member understands their tasks and contributions to the overall project. This helps reduce the risk of unequal workload distribution and lack of participation.

To achieve effective task allocation and maximize project outcomes, responsibilities are assigned based on each team member’s skills, field of study, and previous experience. This approach ensures that tasks are aligned with individual competencies, promoting efficiency, accountability, and overall team performance.

Academic supervisors from ISEP act as a key stakeholder by providing guidance, feedback and evaluation throughout the project. Their role is essential in ensuring that the project meets academic and technical standards.
External stakeholders include research institutions, Non Governamental Organizations (NGOs) and governmental organizations governmental organizations interested in marine conservation and environmental monitoring. These stakeholders are potential future users or partners, as they can benefit from the data collected and the ecological impact of the solution.

Although marine life cannot be considered a traditional stakeholder, it is the primary beneficiary of the project. Therefore, its needs are considered throughout the design process to ensure that the solution is environmentally safe and supportive of biodiversity

Communications

Effective communication was essential to ensure coordination and steady progress throughout the project. Communication within the team was primarily facilitated through daily Scrum meetings, where members discussed completed tasks, ongoing work, and upcoming activities. These meetings helped maintain alignment, identify challenges early, and ensure continuous progress.

In addition, regular communication with key stakeholders, particularly project supervisors, was maintained through weekly meetings held on Thursdays. These sessions provided valuable feedback and guidance, supporting informed decision-making throughout the project. Furthermore, collaborative tools such as Microsoft Teams were used to support documentation, information sharing, and quick communication among team members.
Altogether, this structured communication approach contributed to efficient collaboration, transparency, and timely problem-solving.

Risk

The project involves several potential risks related to both technical and organizational aspects. One of the main risks is technical failure, particularly in the integration of sensors, electronics, and structural components in a marine-like environment. To reduce this risk, the system is tested in controlled conditions and components are selected based on reliability and compatibility.

Another significant risk is project delays due to time constraints and task dependencies. This is managed through sprint planning, regular meetings, and the use of buffer time to accommodate unforeseen issues.

There is also a risk related to limited resources, including budget constraints and access to specialized equipment or testing environments. This is addressed by prioritizing essential features and selecting cost-effective solutions.

Team-related risks such as miscommunication or uneven workload distribution may affect progress. These risks are mitigated through regular Scrum meetings, clear task allocation, and continuous collaboration among team members (see Table 5).

Table 5: Table of different risks
Risk Description Probability Impact Risk Level Mitigation Strategy
Technical failure (sensors/electronics) Failure in integration of sensors, electronics, and structure in marine conditions Medium High High Test components and validate system
Power system failure (battery/solar) Unstable or insufficient energy supply affecting system performance Medium High High Optimize energy use and include backup
Integration issues (hardware/software) Difficulties combining system components effectively Medium High High Modular design and incremental testing
Project delays Delays caused by time constraints and task dependencies Medium High High Sprint planning, regular meetings, and buffer time
Limited resources Budget constraints and limited access to equipment or testing environments Medium Medium Medium Prioritize essential features and use cost-effective solutions
Team miscommunication Lack of coordination or unclear communication within the team Low Medium High Regular Scrum meetings and clear communication
Uneven workload distribution Some team members contribute less, affecting progress Low Medium Low Clear task allocation and team collaboration
Loss of buoy connection (data/power cable failure) Interruption of data or power transfer between buoy and system Low High High Reinforced cables and redundancy
Corrosion of metallic components Degradation due to exposure to saltwater Medium Medium Medium Use corrosion-resistant materials (BFRP, coatings)
Extreme weather (storms, currents) Harsh conditions affecting stability and performance Low High Medium Stable structure and secure anchoring
Waterproofing failure (IP68 breach) Water entering electronic components causing malfunction Low High High Seal testing and proper enclosure
Data transmission failure Loss or interruption of data communication Medium Medium Medium Local data storage and redundancy

To further support the risk assessment, a risk matrix based on probability and impact was used. The matrix classifies risks into three categories: low, medium, and high, depending on their likelihood of occurrence and potential impact on the project.

Based on this matrix, risks such as technical failure, power system failure, integration issues, and project delays are classified as high risk, as they combine medium to high probability with high impact. These risks require priority attention and mitigation (see Figure 6).

Risks such as limited resources, corrosion, extreme weather conditions, and data transmission failure fall into the medium-risk category. These are monitored and addressed through preventive design measures and planning.

Lower-risk factors, including team miscommunication and uneven workload distribution, are classified as low risk, as they have limited impact and can be managed through regular communication and task organization.

The use of this risk matrix provides a clear and structured way to prioritize risks and supports more effective decision-making throughout the project.

Project Plan

Gantt Chart

The project schedule was visualized using a Gantt chart to illustrate the timeline and key phases of the project.

As shown in Figure 7, the project timeline spans from March to June and includes overlapping phases such as research, prototype development, and documentation.

Figure 7: Gantt chart showing the project timeline from March to June.
Global Sprint

The global sprint plan provides an overview of the project timeline, including the duration of each sprint, start and end dates, and the number of available working days. Its main purpose is to ensure a realistic distribution of workload based on the team’s availability throughout the project period. See Table 6 for the global sprint plan.

By defining how long each sprint lasts and how many working days are available, the team can better plan tasks and avoid overloading specific periods. Variations in working days reflect differences in availability, such as holidays or other commitments, which allows for more accurate and achievable planning.

The tasks in the sprint were divided into smaller activities, including research, documentation, design, and planning, in order to ensure efficient progress. Responsibilities were distributed among team members based on their respective roles, with a focus on areas such as research, documentation, and design. By the end of the sprint, key project elements such as clearly defined team roles, initial research, and planning documents had been completed, providing a solid foundation for the subsequent sprints.

Sprint Outcomes

The sprints officially started from 19 March to 26 March, as the previous weeks were mainly used to become familiar with Jira and project tools.

However, the initial work began earlier, and the first weeks were structured as follows:

An overview of the outcomes from the initial sprints is presented in Table 9 and Table 10.

Table 9: Week 1 outcome
Sprint Period Objective Activities Outcome
1 Week 1 Define project scope and direction Brainstorming of project ideas, discussion of possible approaches, evaluation of feasibility Selection of project concept and initial understanding of project scope
Table 10: Week 2 outcome
Sprint Period Objective Activities Outcome
2 12 Mar – 19 Mar Develop system concept and research state of the art Continued research on artificial reefs and sensors, worked on the state of the art chapter, explored materials and structural ideas, started defining system components, followed milestone plan Clearer understanding of technical solutions and initial system concept defined

Sprint 3 The burndown chart for sprint 3 shows that additional tasks were identified and added at the beginning of the sprint, resulting in an increase in the total amount of work. This reflects a better understanding of the project requirements as the team moved from concept to design.

During the middle of the sprint, progress remained relatively stable, indicating that fewer tasks were completed in that period. Towards the end of the sprint, a significant decrease in remaining work can be observed, showing that most tasks were completed close to the deadline.

This pattern indicates that the team made substantial progress during sprint 3, particularly in the final phase, where key design elements and system components were defined. It also highlights the need for improved task distribution to ensure more consistent progress throughout the sprint (see Figure 8).

Figure 8: Week 3 burndown chart

Sprint 4

The burndown chart for Sprint 4 shows a noticeable increase in workload at the beginning of the sprint, indicating that additional tasks were identified as the project scope became clearer. This reflects an ongoing refinement of requirements and system definition. Shown in Figur 9.

Throughout most of the sprint, progress was relatively slow, with only minor reductions in remaining work. A more significant decrease occurs towards the end, suggesting that many tasks were completed close to the deadline.

This pattern indicates that work was concentrated in the final phase of the sprint. Although the planned objectives were achieved, this approach suggests a need for better time management and a more even distribution of tasks across the sprint.

Figure 9: Week 4 burndown chart

Sprint 5

The burndown chart for Sprint 5 shows no significant changes in the remaining workload throughout most of the sprint. This indicates that tasks were not actively tracked or completed within the sprint period. Week 5 is shown in Figure 10.

This sprint coincided with the Easter holiday, during which no substantial work was carried out. Additionally, the project management tool (Jira) was not updated during this period, resulting in a lack of visibility and progress tracking.

The sprint did not function as intended and cannot be considered effective from an Agile perspective. The absence of recorded progress highlights the importance of maintaining consistent engagement and updating project management tools, even during periods of reduced activity.

Figure 10: Week 5 burndown chart

Sprint 6

The burndown chart for Sprint 6, shown in Figure 11, indicates limited progress during the initial phase of the sprint, suggesting that relatively little work was carried out at the beginning of the period.

Subsequently, an increase in the remaining workload can be observed. This is explained because the incomplete tasks from Sprint 5 were carried over into Sprint 6. As a result, the workload appears to increase rather than decrease at that stage.

Towards the end of the sprint, a noticeable reduction in remaining work is observed, indicating that several tasks were completed before the sprint was concluded.

This pattern reflects an improvement in task completion compared to the previous sprint. However, it also highlights the importance of maintaining consistent progress and timely updates in order to ensure accurate tracking and effective sprint execution.

4.1 Introduction

The marketing plan for MARIS HABITATS moves beyond traditional product promotion to define a niche within the emerging blue economy. Currently, the market is split between high-end scientific monitoring equipment and low-tech habitat restoration structures; the strategy identifies the opportunity for a hybrid value proposition.

By assessing the global market environment—where artificial reefs are already utilized in over 40 countries— the position for the product is as a dual-purpose tool for both ecosystem support and operational data collection. This chapter explores the target user personas, from environmental NGOs to commercial fisheries, and outlines how structural complexity and material choice serve as key differentiators in a competitive environmental landscape.

4.2 Business Idea Formulation

The ocean is losing its natural habitats at an alarming rate. This isn't just an ecological tragedy; it is an economic crisis. The degradation of marine environments leads to:

  • Trophic Cascades: The collapse of food chains disrupts global fish stocks, endangering food security [50].
  • Economic Volatility: Decreased supply leads to hyper-inflation in the $400B+ global seafood market [51] [52].
  • Loss of Ecosystem Services: Without bottom-cleaning species and reef barriers, ocean contamination increases and coastal erosion accelerates, threatening billions in real estate [53].

This solution bridges the gap between waste management and marine restoration through two proprietary pillars: Eco-Engineered Recycled Glass: The transformation of waste glass (primarily SiO2) into pH-neutral, bio-receptive modular structures. This diverts waste from landfills while providing a superior substrate for coral and mollusk calcification. Recoverable “Smart” Modules: Unlike traditional “dumb” reefs, our structures are equipped with a modular sensor suite. Once the habitat reaches a self-sustaining maturity (Phase 1), the most expensive component—the electronics—is recovered and redeployed, drastically reducing the Customer Acquisition Cost (CAC) for future projects.

While the “users” are marine life, the paying clients are the human beneficiaries of a healthy ocean. Operations in the emerging Blue Carbon and Biodiversity Credit markets, targeting the $700 billion annual financing gap in nature restoration [54].

  • Primary Clients: National and regional governments seeking coastal protection and climate adaptation [55].
  • Secondary Clients: The insurance and tourism industries, which rely on reef barriers to mitigate storm damage and attract revenue [56].
  • Stakeholders: Environmental, social, and governance (ESG)-focused corporations looking to meet “Nature Positive” mandates by funding habitat restoration [57].

Marine restoration requires significant upfront Capital Expenditure (CAPEX). To move beyond “blind trust,” a Data-as-a-Service (DaaS) model is used:

  • Phase 1: Validation. Small-scale deployment to prove the biocompatibility of our recycled glass.
  • Phase 2: Revenue Generation. Sale of biodiversity offsets and real-time environmental data (pH, temperature, biomass) to research institutions and NGOs.
  • Phase 3: Scale. Massive deployment funded by government “Blue Bonds” and coastal protection grants.

Impact Note: The “price” of our intervention is high, but the cost of inaction—the total collapse of coastal economies—is infinitely higher. We aren't just building reefs; we are building Climate Insurance.

4.3 Business Model Canvas

In this part we are going to present the business model canva, the next image is a initial white board with quick ideas from the brainstorming. Then every section is explained ahead. Same colour post-its refer to the same customer/partner/activity related by colours (see Figure 12).

Figure 12: Business Model Canva

1. Customer Segment We are creating a product for the fish and the sea-life, they are a very niche market where few people are helping. It is very diversified but we will try to narrow it down. Concerning who are we selling our product to, it is intended to be bought by governments and non profit organizations, who are the ones gaining the secondary advantage of the impact. A third part is involucrated, not the fish as the main beneficiary, or the society because the improvement in general of the seas, but also the science, since we will be working with researching institutions to manage the data we will recollect.

2. Value Proposition For the sea-life, we propose an improvement on the life quality and the environments in order to provide shelter and increase the reproduction. For the researching institutions we will try to provide them high quality data usable to many research purposes. For governments it is interesting since it will help restore the sea life, this helps in the water quality for human use, the quality and the price of the fishes in the market, and improves the general quality of society

3. Channels Mainly we will focus on reaching our buyers personally, but also create social awareness and transparency via website and social media.

4. Customers Relationships With the underwater life, we will try to have 0 contact to not disturb them. With the researching centers, we provide real time data by automated services, and we also ask for reports and the manegment to be shared for multiple places co-operation. And for the governments we will be looking forward to long term environmental partnerships that allow a good investment foundation

5. Revenue Streams The governments through different funding programs for sustainable programs and we will try different non-profit organizations to give us some extra money for the project in order to restore the sea. Also look for private funding from philanthropist and private NGO

6. Key Resources Our main resource is the place where we are gonna work, a facility that has to have a first area where to research and work in our computers, and a second area fully dedicated to build the models, from modeling the materials, to implement the sensors, and test them. If we are about to produce the structures in mass, we Will need a factory to produce them sequentially and fast.

7.Key Activities From all the steps of the process, we are gonna handle the design and building of the hábitats, incluiding the instalation of the sensors. And with all that the installation of the hábitats on the seabed and initialization. But about the managin of the data, we Will let that to the researching centers and institutions.

8. Key Partners From the governments we expect not only for them to be our clients, but also to help us with the emplacement locations, as well with some regulation about fishing in those places. Our relation with the institutions Will help us both, they Will have some data to work with, and they Will provide us with feedback about the project. We Will also look for a partnership with some marine business as bouy deployers, big ships owners or divers enterprises for help us with the transportation and deployment in the sea.

9. Cost Structure The whole Bill Will divide among the model (the materials cost and the process to build it), the sensors and all the electronics materials needed, and the cost asociated with the deployment (ship, deliver, divers…) As well the workers salaries in case we go bigger to mass production.

4.4 Market Analysis

Marine ecosystem degradation is increasingly recognized as both an environmental and economic challenge. The decline of marine habitats has been associated with reduced fish stocks, loss of coastal protection, and greater exposure to climate-related risks such as erosion and storm damage [58], [59].

Artificial reefs have been widely implemented as a restoration strategy across different regions of the world. However, most existing solutions are designed as passive structures, providing physical habitats without the ability to monitor environmental conditions or assess their ecological performance in real time [60], [61].

At the same time, there is a growing demand for data-driven environmental management. Public authorities, research institutions, and environmental organizations increasingly require measurable and real-time data to support decision-making processes and justify investments in restoration projects.

This situation reveals a clear gap in the current market. Traditional artificial reefs are capable of providing structural support for marine life, but they lack monitoring capabilities. Conversely, environmental monitoring systems can generate valuable data, yet they do not contribute directly to habitat formation. The proposed solution aims to bridge this gap by integrating both functions into a single system.

The primary target market consists of institutional clients, particularly government agencies, research institutions, non-governmental organizations, and coastal infrastructure operators. In addition, secondary stakeholders include sectors such as insurance, tourism, and corporations focused on ESG objectives.

Market growth is supported by several converging trends. These include the expansion of blue carbon and biodiversity credit markets, the increasing adoption of nature-based solutions, the rising demand for IoT-based environmental monitoring technologies, and the transition toward circular and sustainable materials.

The economic potential of this sector is significant. The global seafood market exceeds 400 billion USD, while there is an estimated annual financing gap of approximately 700 billion USD in nature restoration efforts [62], [63].

Given these conditions, the most feasible market entry strategy is based on gradual validation. Initial deployment through pilot projects, research collaborations, and government-funded trials allows the solution to be tested and refined before scaling through public funding mechanisms and environmental credit markets.

4.4.1 PESTEL ANALYSIS

A Pestel analysis is a tool used by many businesses to study the general enviroment in order to decide a business strategy. This general environment is divided in several segments from the industry and competitor environment. We are doing this analysis for identify changes in society to adapt and integrate the business over it.

4.4.1.1 Political

Politically, we find ourselves in a highly advantageous position. The European Union (EU) has also identified the same problem as we have and has addressed it by publishing The Nature Restoration Law (NRL) [64], which mandates that member states take corrective action. This is where our involvement comes in: faced with a sudden surge in demand, our market supply position is excellent, making the participation of government agencies in our project even more likely.

Following the framework of section 4.4.2.1, the United Nations (UN) has also published The High Seas Treaty (BBNJ) [65]. This international law reaches more than 60 nations and provides a legal framework for establishing Marine Protected Areas (MPAs) in international waters, emphasizing area-based management tools and environmental impact assessments in the deep seas. This benefits our operations as it aligns perfectly with our business proposal and provides a structured framework for us to follow.

4.4.1.3 Economic

Economically, 2026 has marked a leap from research to large-scale implementation, and the funds and budgets allocated to these efforts have grown accordingly. In line with the previously mentioned points and regulations, various organizations have made substantial amounts available:

  • The EU, through the LIFE Program [66], is financing approximately 60–70% of projects with grants ranging between €1M and €5M for those within the “Nature and Biodiversity” calls. Furthermore, under the specific mission “Restore our Ocean and Waters,” calls have been launched with a budget exceeding €115M for nature-based solutions and habitat mapping.
  • The UN, following the BBNJ Treaty, has also activated the Global Environment Facility (GEF) [67] with a total fund of €5.3B, which supports environmental challenges through projects similar to ours. From this special fund, 50% is being allocated to finance large protected areas in international waters.
  • Lastly, at the national level, both Spain and Portugal (both potential target locations) have initiatives such as the PLEAMAR [68] and Empleaverde+ [69] programs, or the NextGen funds (Spain), as well as the Blue Fund (Fundo Azul) [70] and the 2026 State Budget (Portugal). All of these collectively aim toward fishing sustainability, marine restoration, and ecosystem recovery.
4.4.1.4 Social

On a social level, we also possess arguments that gain momentum year after year. The restoration and creation of habitats have their primary impact on the creation of “shelter zones.” This allows for an increase in biomass, which socially stabilizes the economy of fishing areas and reduces conflicts arising from resource scarcity [71]. Furthermore, these habitats indirectly boost diving tourism by diverting tourist pressure from overexploited natural reefs toward controlled, managed areas, promoting a sustainable blue economy [72].

In addition, the improvement of marine habitats enhances water quality and protects beaches from erosion. This increases the overall quality of life in coastal cities, particularly in high-tourism regions such as our target countries, Spain and Portugal.

4.4.1.5 Technological

Technologically, we find ourselves at our least robust point. We are currently in a boom where everything must be monitored, recorded, and measured to demonstrate efficacy and numerically evaluate utility [73]. Funding bodies, in particular, need and demand project reliability. We rely on a simple system that allows us to meet these requirements without overcomplicating the process.

Other projects involve 3D scanning of the implementation or restoration area for simulations, or high-resolution mapping using sonar. However, our goals do not include these types of systems; due to the technological gap, we prefer a simpler monitoring system to provide the necessary security without resorting to excessive, highly invasive, and ultimately unnecessary testing.

4.4.1.6 Enviromental

The implementation of marine habitats is subject to strict oversight by regulatory bodies under the EU Nature Restoration Law [74], which require studies proving that the intervention will not negatively alter the pre-existing dynamics. To this end, Baseline characterization studies are conducted for subsequent comparison after implementation.

Another study of great importance is ecological connectivity to assess interaction with the environment; this will be our Gold Standard for creating ecological corridors that facilitate species migration and climate change adaptation [75]. Finally, other impact assessment and ecosystem service studies will also support our project to ensure its success.

Despite all these well-defined tests and studies, this area may prove challenging, as there are many regulatory requirements to meet and we have limited professional experience in the field. Consequently, we will intensify our efforts to satisfy both technical and social requirements.

4.4.2 SWOT Analysis

We will analyse the different characteristics inside the Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis that are resumed in the Figure 13

4.4.2.1 Strengths
  • Integration of artificial reef structures with IoT-based real-time environmental monitoring systems
  • Use of sustainable and eco-friendly materials (e.g., recycled glass, eco-concrete)
  • Enhanced durability through advanced materials (e.g., nano-SiO₂, basalt fiber reinforcement)
  • Contribution to biodiversity restoration, coastal protection, and ecosystem services
  • Ability to generate continuous environmental data for research and decision-making
4.4.2.2 Weaknesses
  • High initial development and deployment costs (CAPEX)
  • Technical complexity of integrating sensors, materials, and marine infrastructure
  • Long-term maintenance requirements in harsh marine environments
  • Dependence on reliable energy sources (solar/wave) for continuous operation
  • Need for validation and certification before large-scale deployment
4.4.2.3 Opportunities
  • Growing global investment in marine ecosystem restoration and climate adaptation
  • Expansion of blue carbon and biodiversity credit markets
  • Increasing demand for data-driven environmental monitoring solutions
  • Government policies supporting nature-based and coastal protection solutions
  • Potential partnerships with research institutions, NGOs, and environmental agencies
4.4.2.4 Threats
  • Harsh marine conditions (corrosion, biofouling, storms) affecting system lifespan
  • Regulatory and permitting challenges for marine deployment
  • Competition from established artificial reef solutions and ecological infrastructure companies
  • Risk of system or sensor failure impacting data reliability
  • Uncertainty in long-term funding and policy support
Figure 13: SWOT Analysis

4.5 Strategy

4.5.1 Strategic Objectives

To determine our objectives, we will follow a SMART framework, ensuring our goals are Specific, Measurable, Achievable, Relevant, and Time-bound. We have defined a 3 to 5-year horizon to minimize ambiguity and ensure strategic alignment.

  • Short-to-Medium Term: The primary objective is to demonstrate the system's feasibility through a functional prototype and establish strategic partnerships with research institutions, NGOs, and local authorities for pilot deployment.
  • Long Term: Beyond the initial scope, the project aims to scale the solution into a modular and sustainable artificial reef system dedicated to marine ecosystem restoration and data-driven coastal management.

Monitoring, Metrics, and Baselines The implementation of specific and measurable Key Performance Indicators (KPIs) will serve as the project’s compass. We will utilize a longitudinal monitoring approach, comparing post-deployment data against a rigorous environmental baseline (the “Year 0” measurements). This comparative analysis is the only scientifically valid method to quantify biodiversity net gain, water quality improvement, and structural integrity over time.

Critical Relevance in a Global Context The urgency of these objectives cannot be overstated. As detailed previously, marine ecosystems are approaching a critical tipping point. The degradation of these habitats threatens keystone species responsible for essential ecosystem services, including global oxygen production—driven by phytoplankton and healthy reef systems—and the sustenance of human populations that rely on the sea for food security. Our strategy is not merely a business goal; it is a response to a global ecological imperative.

Achievability and the “Experimental” Paradigm In alignment with the World Wide Fund for Nature (WWFs) classification, this project is categorized under the Experimental Frontier. Unlike “Mature” projects with predictable outcomes, ours operates in a dynamic environment where we must push technical boundaries. Recognizing this “experimental” nature allows us to maintain operational flexibility. We acknowledge that marine variables—such as current shifts, temperature fluctuations, and pH levels—require an adaptive management style, allowing us to pivot our tactics without compromising our core strategic objectives.

4.5.2 Segmentation and Targeting

[Original Version]

Unlike traditional consumer products, our solution is not defined by standard demographic or psychographic segments. Instead, our segmentation strategy is geographically and ecologically driven, focusing on coastal regions that share specific environmental parameters.

Currently, our primary focus is the Atlantic coast of Portugal and Northern Spain. These regions share nearly identical marine conditions and biodiversity profiles, allowing us to optimize our system's performance across multiple sites with minimal structural adaptation.

While the EU is our primary institutional ally and initial market, our long-term scalability plan involves expanding to analogous maritime environments globally. Our expansion roadmap targets regions with similar “Cold-Temperate” or “Upwelling” ecosystems, such as the Northeastern U.S., Southwestern Canada, Western New Zealand, and Central Chile.

In future phases, we aim to diversify our technology to accommodate different climates—ranging from tropical to arctic conditions—maximizing our global footprint and impact on marine restoration.


From this perspective, our targeting strategy focuses on the stakeholders and key beneficiaries within our geographical segments. Having established where the system will be deployed, we must now define who benefits from its implementation to justify and analyze the required investment.

The primary environmental impact of our project is the restoration of marine biodiversity in coastal areas, which facilitates the growth of fish populations and improves overall water quality. Additionally, a significant socio-economic benefit is the mitigation of coastal erosion and current control. By buffering the impact of storms and high-energy waves, our system enhances the resilience of coastal communities and protects critical infrastructure.

Consequently, our primary target audience consists of national and regional governments, as well as coastal municipalities. Given the specialized nature of our solution and the limited direct competition, prioritizing governmental entities and the public sector as our lead stakeholders is a strategic imperative.

Our partnership with these entities is based on three critical criteria:

  • Environmental Awareness: The urgency of addressing marine degradation.
  • Financial Capacity: The ability to allocate long-term infrastructure investment.
  • Strategic Alignment: Consistency with global sustainability mandates.

In this context, the EU 2030 Biodiversity Strategy serves as a definitive catalyst, ensuring that our objectives are perfectly aligned with the EU's regulatory and funding frameworks.

[Updated]

Unlike traditional consumer products, our solution is not based on standard demographic or psychographic segmentation. Instead, it focuses on geographical and environmental conditions, especially coastal areas with similar marine characteristics.

At this stage, the main focus is on the Atlantic coast of Portugal and Northern Spain. These regions have similar ocean conditions and biodiversity, which makes it easier to apply the system without major design changes.

Although the European Union is the main institutional partner and initial market, the long-term goal is to expand to other regions with similar marine environments. Potential areas include the northeastern United States, southwestern Canada, western New Zealand, and central Chile.

In future developments, the system could also be adapted to different climates, including tropical and colder regions, allowing for wider global application.


From this perspective, the targeting strategy focuses on the main stakeholders within these regions. After identifying where the system can be implemented, it is important to define who benefits from it.

The project aims to improve marine biodiversity, support fish population growth, and contribute to better water quality. In addition, it can help reduce coastal erosion and protect coastal infrastructure by absorbing wave energy.

Unlike traditional solutions, the system also includes an integrated monitoring component that provides continuous environmental data. This supports data-driven decision-making for coastal management and long-term planning.

For these reasons, the main target audience includes national governments, regional authorities, and coastal municipalities. These stakeholders are responsible for environmental management and have the capacity to invest in long-term infrastructure.

The partnership strategy is based on three main criteria:

  • Environmental awareness: recognition of marine ecosystem degradation
  • Financial capacity: ability to support long-term investment
  • Strategic alignment: consistency with sustainability policies

In this context, the EU Biodiversity Strategy for 2030 provides a strong framework, as it aligns with the objectives of this project and supports funding opportunities.

4.5.3 Positioning

The positioning of the proposed Maris Habitats system and existing solutions is shown in Figure 14. The map is based on two main criteria: ecological enhancement (horizontal axis) and technological integration (vertical axis). These criteria help to compare how different solutions focus either on environmental impact or on the use of technology.

On the left side of the map, solutions such as MEITEC can be found. These systems mainly focus on structural support for marine environments using conventional concrete. While they contribute to habitat creation, they do not include advanced monitoring or data collection features, which explains their lower position in terms of technological integration.

On the right side, ECOncrete and Living Seawalls are placed due to their strong focus on ecological improvement. These solutions are designed to support marine life by using eco-friendly materials and surface designs. However, they are positioned lower on the map because they do not include integrated sensors or real-time monitoring systems.

IntelliReefs is located slightly above these solutions. This reflects its more advanced structural design, especially through modular reef systems. Even so, it still does not provide significant technological integration in terms of environmental data collection.

Reef Design Lab is positioned in the central-right area. Their use of innovative design approaches, such as 3D-printed reef structures, increases habitat complexity. However, similar to other solutions, real-time monitoring is not a key feature.

Biorock appears in the upper-right part of the map. This is due to its use of electrical currents to support coral growth, which introduces a higher level of technological involvement while still maintaining strong ecological benefits.

The proposed Maris Habitats system is positioned in the upper-right section of the map. This reflects its combination of ecological design and technological integration. Unlike other solutions, it includes an integrated monitoring system that allows continuous data collection and supports more informed decision-making.

Overall, the positioning map shows that most existing solutions focus mainly on ecological enhancement or structural design, but not both together with technology. This highlights a gap in the current market, which Maris Habitats aims to address.

5.1 Introduction

This chapter examines the environmental, economic and social dimensions of the project, as well as the product’s life cycle, in order to assess its overall sustainability. The aim is to highlight the considerations taken to minimize negative environmental impacts when introducing artificial structures into marine ecosystems.

Particular attention is given to ensuring that the solution does not further disrupt or degrade existing ocean environments. This includes evaluating how the design, material selection, and long-term use of the product can prevent pollution and reduce ecological harm. By adopting a lifecycle perspective, the chapter also addresses how the product can be managed responsibly from production to end-of-life.

5.2 Environmental

This section considers the environmental impact of the project using principles inspired by the butterfly diagram, a model that represents circular material flows [76]. The model distinguishes between biological processes, where materials safely integrate into natural systems, and technical processes, where products are maintained, reused, and recycled to extend their lifespan (see Figure 18).

The MARIS HABITATS concept reflects these principles by combining long-term environmental integration with efficient use of technical components. From a biological perspective, the habitat is designed to function as part of the marine ecosystem over time. The use of non-toxic and durable materials allows marine organisms such as algae and microorganisms to attach and grow on the structure, gradually transforming it into an artificial reef. In this way, the structure contributes positively to biodiversity rather than becoming waste.

From a technical perspective, the system is designed with longevity and adaptability in mind. The structure itself is intended to remain in the environment for long periods, while the electronic components are treated as separate elements. Sensors and electronic modules can be replaced, upgraded, or removed without disturbing the entire habitat, which reduces material waste and extends the usability of the system.

Maintenance is minimized through the selection of robust materials that can withstand harsh marine conditions. However, when intervention is required, the modular design allows specific components to be handled individually. This approach reduces unnecessary replacement and supports more efficient resource use.

The project also considers the potential for reuse and recovery of electronic components. Once the habitat has reached a stable ecological state, parts of the monitoring system can be redeployed in new installations. This reduces both environmental impact and overall system cost.

Recycling is addressed through the selection of materials that either have recycled content or can be processed at the end of their technical life. Although the structure is intended to remain in the environment, the design avoids materials that could cause long-term harm.

Figure 18: Butterfly diagram [77]

5.3 Economical

The economic aspect of MARIS HABITATS is mainly related to the long-term benefits created through ecosystem restoration and its integration with existing marine infrastructure. By improving marine biodiversity and supporting the growth of fish populations, the system contributes to increased fishery productivity over time. This can generate direct economic benefits for local communities that depend on fishing as a source of income and food.

Previous studies have shown that artificial reefs can increase fish biomass and support the development of fisheries, which can lead to economic improvements in coastal areas [78]. In this project, this principle is applied through the design of habitat structures that provide shelter and breeding areas for marine species.

The system is also designed to be integrated with existing marine infrastructure, such as offshore wind farms or coastal protection systems. This approach avoids the need for completely new structures and allows existing installations to be enhanced with ecological functions, improving resource efficiency.

The integration of sensors adds an additional layer of economic value. The system continuously collects environmental data, which can be used for research, monitoring, and decision-making. In this project, this data supports more efficient management of marine resources and can help reduce costs associated with poor environmental monitoring.

Another important aspect is the modular and scalable design of the system. Habitat units can be deployed gradually and adapted to different marine environments, reducing the need for large initial investments. This allows pilot implementations to be carried out before full-scale deployment.

The modular monitoring system also contributes to lower maintenance costs. Instead of replacing the entire structure in case of failure, only specific components need to be repaired or replaced. This improves operational efficiency and reduces long-term costs.

In addition, the project can benefit from collaboration with public institutions, research organizations, and environmental programs. Marine restoration and biodiversity protection are increasingly supported by sustainability policies and funding initiatives [79]. This creates opportunities for financial support through grants and public-private partnerships.

Although the initial investment may be relatively high, the long-term benefits are expected to outweigh these costs. These benefits include improved ecosystem services, increased fish production, and enhanced coastal protection [80]. For this reason, MARIS HABITATS can be considered not only environmentally sustainable, but also economically viable in the long term.

5.4 Social

The project contributes to social sustainability by supporting marine ecosystems that are vital to the livelihoods and well-being of coastal communities. Healthier fish populations can enhance food security, strengthen local economies, and promote sustainable fishing practices.

The integration of environmental sensors facilitates the collection of valuable data that can be used for research, education, and public awareness. This supports knowledge sharing and fosters innovation within marine science and environmental management.

The project aligns with the principles of inclusive and collaborative development, particularly in relation to Sustainable Development Goal (SDG) 17 (Partnerships for the Goals) [81]. Promoting cooperation between governments, research institutions, local communities, and environmental organizations, the project fosters a collaborative approach that strengthens shared responsibility and encourages collective action. The active involvement of local stakeholders in the planning, implementation, and monitoring processes enhances transparency, builds trust, and ensures that the project reflects community needs and values. Such participatory practices are essential for achieving long-term social acceptance and sustainability.

5.5 Life Cycle Analysis

The life cycle of the project is considered from material selection to end-of-life, with the aim of minimizing environmental impact while ensuring long-term functionality.

In this project, the material phase focuses on selecting environmentally responsible and durable materials. The proposed solution uses basalt fiber-reinforced concrete. Basalt fibers are derived from natural volcanic rock and are known for their resistance to corrosion and chemical stability in saline environments, making them suitable for marine conditions [82]. Electronic components, including the microcontroller, are also selected based on energy efficiency, reliability, and expected lifespan.

During the manufacturing phase, the habitat structure is produced and the sensor system is integrated. In this project, the structure is designed to be manufactured using relatively simple casting processes, which helps reduce energy use and material waste.

The testing phase involves validating both the structural performance of the habitat and the functionality of the sensor system. In this project, particular attention is given to energy consumption, battery life, and reliable data collection, as these factors directly influence maintenance requirements.

The structure is also designed for long-term environmental integration. Its geometry includes cavities and irregular surfaces that support marine colonization, allowing the habitat to remain functional even if some parts degrade over time.

To reduce environmental risks, the monitoring system is designed as a separate modular unit containing the sensors. This unit can be retrieved for maintenance, data collection, or replacement without disturbing the main structure. By separating the electronic components from the permanent habitat, the design reduces the risk of long-term pollution.

At the end-of-life stage, the structure is intended to remain in the marine environment and gradually integrate into the ecosystem, functioning as an artificial reef. Instead of becoming waste, it continues to support biodiversity [83]. The electronic components can be removed and reused or redeployed in new systems, contributing to more efficient resource use.

5.6 Summary

This chapter has examined the environmental, economic, and social dimensions of the project, together with a lifecycle perspective, in order to evaluate its overall sustainability. The analysis highlights the importance of minimizing environmental impact while ensuring long-term functionality, economic viability, and social value.

Based on this sustainability analysis, the team selected a modular habitat design combined with a separate monitoring system and the use of basalt fiber-reinforced concrete as the primary structural material. This choice is supported by its durability, resistance to marine conditions, and suitability for long-term deployment without causing environmental harm. In addition, the separation of electronic components from the main structure contributes to reducing pollution risks and improving resource efficiency.

Consequently, the solution was designed with features that support sustainability throughout its lifecycle. These include a structure that can integrate into the marine ecosystem over time, a modular and retrievable sensor system that enables maintenance without disturbing the habitat, and a design that promotes marine colonization through varied shapes and surface characteristics. Together, these elements ensure that the system not only minimizes negative environmental impacts but also contributes positively to marine biodiversity and long-term ecosystem health.

6.1 Introduction

This chapter outlines the ethical and deontological principles guiding the development of a smart artificial marine habitat. It focuses on ensuring environmental protection, data integrity, and responsible engineering practices, while addressing key considerations such as sustainability, transparency, and long-term system reliability.

6.2 Engineering Ethics

Engineering ethics play an important role in the design and development of artificial marine habitats for endangered fish species. Engineers must ensure that structures are designed with sufficient strength, durability, and reliability to withstand harsh marine conditions such as saltwater exposure and wave forces [84], [85]. This is essential to guarantee long-term functionality and safety.

Engineers also have a responsibility to ensure that both the habitat structures and monitoring systems do not pose risks to marine organisms, installation personnel, or the surrounding environment. Safety and reliability must be considered throughout the entire design process.

Another key ethical consideration is minimizing ecological disruption. Artificial habitats should not damage the seabed or negatively affect existing ecosystems. Instead, they should be designed to support and enhance natural habitats. Studies have shown that well-designed artificial reefs can increase biodiversity and improve marine ecosystem conditions [86].

Material selection is also important. Engineers should choose non-toxic and environmentally sustainable materials that are suitable for long-term use in marine environments.

Transparency is an essential part of ethical engineering practice. Engineers must ensure that all collected data is accurate and reported honestly, regardless of the results. This supports scientific research and contributes to better decision-making in marine conservation.

6.3 Sales and Marketing Ethics

HERNAN: I WILL CHECK THIS

The duty of safety and quality assurance requires that all underwater sensors and electrical components are designed and implemented in a manner that ensures they are safe for both users and marine life. This includes minimizing potential risks associated with system failures by incorporating reliable design solutions and protective measures that reduce the likelihood and impact of malfunctions.

The duty of information transparency emphasizes the importance of providing accurate and accessible data. Sensor data should be disclosed in a clear and reliable manner, allowing stakeholders to assess environmental performance and understand the actual impact of the system on sustainability outcomes.

The duty to maximize economic utility involves supporting clients in achieving cost efficiency over time. This includes designing systems that reduce long-term maintenance requirements and operational costs, thereby increasing the overall economic value of the solution.

6.4 Environmental Ethics

The project aims to support marine ecosystems while minimizing negative environmental impacts. Artificial habitats are designed to promote biodiversity and help restore fish populations without significantly disrupting the surrounding ecosystem.

Material selection focuses on durability and environmental compatibility in order to reduce pollution and long-term ecological damage. Special attention is given to ensuring that the structures do not release harmful substances into the marine environment.

In addition, the project contributes to environmental awareness and education by enabling the collection of monitoring data through integrated sensors. This data can support researchers and local communities in better understanding marine ecosystems and the factors that influence their health.

The design also considers ecosystem balance by supporting species that naturally coexist and avoiding elements that could disturb the existing ecological structure. Studies have shown that ecologically enhanced marine structures can increase biodiversity without compromising structural performance [87].

6.5 Liability

HERNAN: I WILL CHECK IT

Liability relates to the responsibility for potential consequences if the system does not perform as intended. This includes risks such as incorrect environmental data, failure of monitoring components, or unintended interactions with the surrounding marine environment.

Particular attention is given to the reliability of the monitoring system, as inaccurate data could affect research outcomes and decision-making processes. Ensuring proper calibration, testing, and data validation is therefore essential.

Another aspect concerns responsibility in case of long-term system degradation. Even though the structure is intended to integrate into the environment, it is important to ensure that no harmful elements remain if components fail or deteriorate over time.

Clear documentation and transparency are also part of liability, as they define how the system is used, monitored, and maintained. This helps reduce misuse and ensures that responsibility is properly understood.

6.6 Summary

This chapter has examined the ethical and deontological considerations associated with the development of a smart artificial marine habitat. Key aspects included ensuring environmental protection, maintaining data integrity, promoting transparency, and minimizing potential risks related to system deployment and operation.

Based on this ethical and deontological analysis, the team chose a modular habitat design combined with a separable sensor system and durable, environmentally compatible materials such as basalt fiber reinforced concrete. These choices were made to reduce long-term environmental impact, avoid pollution, and ensure that the system can be maintained without disturbing the marine ecosystem.

Consequently, the team decided to design a solution that prioritizes structural stability, safe integration into the seabed, and the ability to retrieve and maintain electronic components independently from the habitat structure. This approach supports responsible engineering practices and reduces potential risks related to system failure and environmental harm.

7.1 Introduction

Transitioning from a theoretical model to a functional underwater prototype involves a rigorous process of synthesis and troubleshooting. This chapter documents the technical execution of the project, detailing the mechanical assembly, electronic integration, and software architecture of the MARIS HABITATS system.

It serves as a technical log of the development lifecycle, highlighting how the theoretical foundations established in Chapter 2 were translated into physical components. From the challenges of ensuring watertight integrity for the sensor housing to the optimization of low-power data transmission, this section provides a comprehensive look at the engineering hurdles overcome during the fabrication and programming phases.

7.2 Ideation

The goal of our project is to design artificial marine habitats that can help endangered fish species and corals thrive again. Climate change and the warming of the oceans are disturbing marine ecosystems and damaging the natural balance of life underwater. Because of this, many species are losing safe places to live, hide, feed, and grow. Our design is therefore focused on supporting nature itself, especially fish, corals, and other marine organisms.

From the beginning, we knew that the structure had to meet several important requirements. It had to be modular, so that different units could be combined and adapted depending on the location and the needs of the ecosystem. It also had to be made from a material that would not harm the marine environment. Since corals need to grow on the structure, the material had to be suitable for marine life and preferably porous. At the same time, the habitat could not be excessively large or heavy, since this would complicate transport and installation. The design therefore had to balance practical deployment with sufficient weight and stability to remain in place and withstand sea currents.

To develop the concept, the team started with brainstorming sessions and research into similar existing projects. Different types of artificial reefs and marine restoration systems were researched, and also which materials could safely be used in the sea were studied. During this ideation phase, the creation of around six to seven different structural concepts was crucial. While the overall shapes of these concepts were quite similar, the main differences were in the materials and possible additional features such as sensors.

It was explored several material options, including basalt fabric-reinforced structures, polymer-clay, bacterial HSC, ECOncrete, recycled glass, and Biorock. Each material had its own advantages and disadvantages. Some were more expensive, while others were less suitable for coral growth or did not provide the level of porosity needed by marine organisms. Since fish and corals benefit from rough and porous surfaces, this became an important factor in our decision-making process.

After comparing the different options, we selected basalt fabric-reinforced concrete as the most suitable material for the project design. This material offered a strong balance between cost, weight, stability, and ecological suitability. It is not overly expensive, heavy enough to remain stable underwater, and easy to shape into modular forms. In addition, its porous surface makes it a good choice for encouraging coral growth and creating shelter for fish. The material can be formed by first making a mould in the desired shape and then placing the basalt fabric or mesh inside it. Depending on the required strength, the fabric can be arranged in one or several layers. Fine concrete or mortar is then poured, sprayed, or pressed around the reinforcement. After curing, the concrete becomes rigid while the basalt fabric remains embedded inside as reinforcement. For these reasons, basalt fabric-reinforced concrete was chosen as the best material for our final concept.

7.3 Concept

The final concept selected for MARIS HABITATS is a modular artificial marine habitat built from one repeated cone-shaped element. These modules can be connected side by side and stacked vertically, allowing the habitat to be expanded according to site conditions and ecological requirements. By using one repeated part, the system remains simple, scalable, and easy to reproduce, while still allowing a wide variety of structural arrangements.

The concept was selected because it provides a strong balance between ecological function and practical feasibility. Different configurations of the same module can create both smaller and larger shelter spaces, making the habitat suitable for a wide range of marine species. This adaptability is one of the main strengths of the concept, since different deployment sites may require different structural densities and sizes.

Another important aspect of the concept is the material choice. The habitat is intended to be made from basalt fabric-reinforced concrete, which combines structural weight and durability with a rough and porous surface suitable for marine colonisation. This surface can support the attachment and growth of algae, corals, and other marine organisms, while the weight of the material helps the structure remain stable under underwater currents.

Compared to other design directions explored during the project, this concept proved to be the most suitable. Earlier ideas such as spherical, hexagonal, and dome-based structures were less effective because they were either not modular enough or too difficult to manufacture and combine efficiently. For this reason, the cone-based modular concept was defined as the final structural direction of the project.

Figure 19: Selected modular unit forming the basis of the final habitat structure.

7.4 Design

7.4.1 Introduction

This section presents how the selected concept was developed into a feasible structural solution for underwater deployment. The design process focused on translating the general concept into a habitat that is modular, manufacturable, stable, and ecologically suitable for marine colonisation. The following subsections explain the main design decisions and the structural directions explored during the development process.

7.4.2 Design

The design phase focused on transforming the selected concept into a structure that could function in an underwater environment while remaining feasible to produce and deploy. From the beginning, the most important design requirement was modularity. The habitat had to be based on one repeatable element that could be combined in multiple ways without becoming too complex to manufacture or assemble. This requirement guided the entire design process and strongly influenced the selection of the final form.

Several structural directions were explored during this phase, including spherical, hexagonal, and dome-like concepts. Although these ideas offered interesting spatial qualities, they were gradually rejected because they did not satisfy the design goals strongly enough. Some concepts were too difficult to produce in a simple and repeatable way, while others did not provide the level of modularity needed to expand the habitat efficiently. In contrast, the cone-based element provided a clearer and more practical solution. Because the same unit can be repeated throughout the structure, the habitat can grow both horizontally and vertically while maintaining a simple and consistent construction logic.

The chosen design also supports ecological performance. By connecting and stacking the modules in different arrangements, the habitat can generate openings and sheltered spaces of different sizes. This is important because smaller and larger marine organisms require different types of refuge. The repeated units also create a more complex three-dimensional environment, which improves habitat quality and increases the suitability of the structure for fish, algae, corals, and other marine species.

Material selection was another important part of the design phase. The final design is based on basalt fabric-reinforced concrete, chosen for its combination of strength, weight, and ecological suitability. The material is heavy enough to improve stability under underwater currents, while its rough and porous surface can encourage biological growth over time. In this way, the design responds not only to structural and manufacturing requirements, but also to the biological purpose of the habitat.

Overall, the design phase transformed the initial concept into a clear and buildable solution. Instead of developing a complex habitat composed of many different parts, the design process focused on a single repeated module capable of generating a wide range of spatial configurations. This decision improved the scalability, manufacturability, and ecological potential of the habitat, and formed the basis for the structural development presented in the following subsection.

7.4.3 Structure

The structural development of the habitat began with a series of exploratory concepts. These early ideas were useful for identifying the design characteristics that were most important for the project, such as modularity, ease of production, structural repetition, and the creation of different shelter sizes. The figures below illustrate the main structural directions considered during this process. Figure 20 shows an initial idea.

Figure 20: Early structural concept exploring enclosed shelter geometry.

One of the first directions explored was a more enclosed structure, shown in the early sketch above. This concept helped define the importance of shelter, internal space, and protection for marine species. However, although it offered enclosed refuge areas, it was not considered the most suitable direction because it did not provide the same level of modular flexibility as later concepts. As the design process continued, greater importance was given to repeatability and scalability.

Figure 21 illustrates the proposed habitat modular design.

v1.0.jpeg

Figure 21: Hexagonal modular concept explored during the structural development.

A second concept was based on a hexagonal module supported by pillars. This idea introduced a stronger modular logic and allowed several units to be connected into a larger structure. The concept was relevant because it explored how repeated modules could create a more adaptable habitat system. It also supported the study of elevated structures and the possibility of generating openings of different sizes. However, this direction was not selected as the final solution because the cone-based concept provided a simpler repeated form and clearer scalability (see Figure 22).

Figure 22: Structural variation exploring different opening sizes and configurations.

Further structural exploration focused on varying the dimensions and arrangement of the elements in order to create openings suitable for different marine species. This stage was important because it highlighted the ecological value of structural diversity. By studying how repeated parts could generate different internal spaces, the development process produced a clearer understanding of how geometry could influence habitat quality. These studies confirmed that the final design should allow variation in shelter size while still remaining based on one simple repeated part (see Figure 19 and Figure 24).

Figure 23: Selected modular unit forming the basis of the final habitat structure.

After comparing the different structural directions, a concept based on one repeated cone-shaped module was selected. This solution was considered the most appropriate because it combines modularity, manufacturability, and ecological functionality. The same unit can be repeated many times, allowing the structure to expand horizontally and vertically while maintaining a simple construction logic. In addition, the arrangement of these modules creates a more complex habitat geometry with multiple shelter opportunities for marine organisms.

Figure 24: Example of the habitat formed by combining multiple modular elements.

When several modules are combined, the habitat can cover a larger area of the seabed and create a more complex three-dimensional structure. This makes the system adaptable to different sites and allows the scale of the habitat to be adjusted according to the intended application. For this reason, the final structure is not defined by a single fixed form, but by a repeatable modular logic that can be expanded according to ecological and practical needs.

7.5 Smart System

7.5.1 Hardware
7.5.1.1 Black Box Diagram

Throughout this project, we explored various approaches to data collection. Initially, Version 1 was developed, while this version enabled continuous data communication, it proved to be highly complex and more prone to potential failures. Based on these findings, Version 2 was selected as the preferred because it prioritises robustness, reduced complexity, and ease of deployment, while accepting compromises regarding limited operational duration and the lack of continuous data communication.

Version 1 (V1) Buoy-Connected System

Figure 25 presents the smart system black box diagram. The system corresponds to a living laboratory where the:

  • Sun (top left corner) is the source of energy. A buoy equipped with solar panels on top will store power in a battery and provide power to the system.
  • Sea water (bottom left corner) is the growth medium. Four sensors will monitor the water environmental conditions (diamond).
  • Fish and sea life (bottom right corner) are under observation. Fish and algae will be monitored (presence and size) to determine biodiversity and measure photosyntethic effects and chlorophyll on surfaces.

All this data will be reunited and sent to the On Board Computer (OBC) while also getting a timestamp by a Real Time Clock (RTC). All this will be powered by the battery through a Power Management System (PMS) that received the power from the buoy.

Both the buoy and the structure will have a positioning module, that will count with an Inertial Measuring Unit (IMU), a Doppler velocity Log (DVL) and a Global Navigation Satellite System (GNSS) receiver, to have everything registered about the position of both elements and make sure nothing goes wrong due to external factors such as storms, currents or human factors.

From the structure to the buoy, there will be a chain and a cable, for both structural support and data and power connection between the 2 elements. Finally, all the data collected will be sent to a data center, this will be done via the standard Iridium Satellite Network.

The main output will be a report with all the obtained data.

In this configuration, the system is based on a “Smart Block” that houses all electronic components, including the power supply, sensors, and data storage, eliminating the need for external infrastructure such as surface buoys, solar panels, or cable connections.

The system is powered by an internal battery designed for approximately 49 days of operation, after which maintenance is required. Environmental data is collected via sensors that measure pressure (depth), temperature, pH, and conductivity. All collected data is stored locally on an SD card; real-time transmission is not possible. Consequently, data retrieval and system maintenance are performed manually by divers, who replace the battery at regular intervals and collect the stored data. After retrieval, the data is transferred to a research facility for analysis and evaluation, ultimately contributing to environmental monitoring and reporting.

7.5.1.2 Electronics

Microcontroller & Battery An Arduino Uno R4 Minima was chosen as the microcontroller. This version does not include WiFi or Bluetooth, but those features do not have any use underwater anyway.

The battery used is a 12 V 10 Ah lead-acid battery. Since it is a lead-acid battery, it should not be discharged more than 50 %.

Based on the total power consumption of the system and the battery capacity, one charge would last approximately 49 days.

To save energy, measurements are performed only once per hour. The system is designed to be active for only 2 minutes per hour, which should be more than sufficient for the sensor values to stabilize and for the data to be written to the SD card.

The total power consumption of the system is 1.505 W.

Battery capacity: 12 V × 10 Ah × 0.5 = 60 Wh

Daily energy consumption (2 min/hour operation): 1.505 W/30​ × 24 h = 1.204 Wh

Number of days: 60 Wh / 1.204 Wh = 49.83 d

Sensors

Selecting sensors was quite challenging, as most sensors such as pH and conductivity probes are designed for temporary measurements and not for long term submersion. Additionally, the sensors must withstand the high pressure at the seabed, and many are not suitable for seawater. This resulted in expensive sensors, mainly sourced from suppliers in the United States.

The BarXT sensor measures both pressure and temperature. From the pressure data, the depth can be calculated. An I2C level converter is required to convert the 3.3 V logic signal to 5 V so it can be read by the Arduino.

The pH sensor is sourced from Atlas Scientific. It is used together with a pH Surveyor, which converts the signal into an analog signal that can be directly read by the Arduino’s analog inputs.

For the conductivity sensor, no similar ready-made solution was available. It outputs a current signal of 4 mA–20 mA, which must be converted into a voltage of 0 V–5 V to be read by the Arduino. This is done using a 250 Ω resistor, according to Ohm’s law (U=I×R).

0.004 A × 250 Ω = 1 V

0.020 A × 250 Ω = 5 V

Enclosure

The enclosure is one of the most critical and costly components of the system, as it must withstand high external pressure at the seabed. Suitable enclosures are therefore difficult to source.

A pressure relief valve is installed to regulate internal pressure. Additionally, condensation is expected to form inside the enclosure due to temperature differences between the internal air and the surrounding environment. To mitigate this, silica gel packets are placed inside the enclosure to absorb moisture.

The sensors from Atlas Scientific use ¾“ NPT threads, while the enclosure is designed with M10 threads. This requires sealing the existing holes and machining new threaded openings in the enclosure.

However, the sensor from Blue Robotics is equipped with M10 threads, allowing direct installation into the enclosure without modification.
