The ecological and hydraulic stability performance of ECOncrete marine mattresses has been validated through biological monitoring, physical model tests, and prototype deployment in offshore environments. 

Marine mattresses are successful in protecting and stabilizing the cable and enhancing biodiversity. This specific design supports the settlement of marine species that would otherwise be absent in heavily engineered environments. In addition, the marine mattresses create niche areas for fish to spawn, shelter, or feed.

By encouraging the growth of algae and supporting fish populations, the marine mattresses contribute to local fisheries and enhance the surrounding marine food web. An extensive physical model test campaign at the Environment Coast and Ocean Research Laboratory in the Polytechnic University of Madrid (Spain) was performed to assess the hydraulic stability of the ECOncrete marine mattresses as a cable protection solution under different boundary and metocean conditions. Preliminary results are expected soon.

• Balance engineering and ecological goals: Offshore wind projects must meet both hydraulic stability and biodiversity enhancement requirements. Validated Nature-Inclusive Design (NID) solutions help developers align with industry standards while supporting marine ecosystems. By focusing on proven, nature-inclusive alternatives, infrastructure projects can support marine biodiversity while maintaining structural integrity and long-term functionality.
• Provide solution performance substantiation: Developers require evidence-based validation for eco-engineered solutions. Solutions must comply with industry-applicable standards and demonstrate durability, hydraulic stability, and ecological benefits.
• Involve solution providers early in the design phase: Bringing in NID experts early allows for design optimization that streamlines permitting, and enhances overall ecological project outcomes. By integrating these strategies, offshore projects can successfully balance infrastructure development with biodiversity enhancement, paving the way for more sustainable marine environments.
• Prioritize local production and materials: Collaborating with local contractors and the use of local materials ensures efficient manufacturing and deployment, supports local economies, and reduces the project’s carbon footprint, which are key factors in meeting regulatory and sustainability goals.
• Optimize design for ecosystem health: Structural NID solutions incorporate eco-friendly features into essential offshore structures that enhance connectivity within the ecosystem. This strategy is key to creating diverse habitats with high connectivity and space for population growth.
• Consider scalability: Offshore projects typically require massive production and deployments of different solutions and elements. All the solutions must be easily scalable and deployed to not interfere in the construction schedule and processes.
