Curaçao’s beautiful coastlines are under threat from coastal erosion. With steep coral terraces that drop rapidly into the deep ocean, traditional coastal defenses, like a rock or concrete sea wall combined with sand nourishment, often falls short. In some cases, they can even harm the very marine environments they aim to protect.

At Blue21, we’re reimagining coastal defense with adaptive, nature-inclusive solutions. Our latest feasibility study, “Floating Breakwaters for Coastal Erosion Control,” explores the possibility of a more adaptive, nature-inclusive alternative structure for the area of Marie Pampoen in Curaçao.

The Three Pillars of Our Feasibility Study

Our team is taking a holistic approach to the Curaçao feasibility study, ensuring that technical performance is integrated with three core pillars:

• Adaptive engineering: Our floating modular system is designed to be adaptive. By analyzing specific wave transformation scenarios (from offshore swells to nearshore breaking), we are developing a system that can be adjusted as climate conditions and sea levels change over time.
• Nature-Inclusive Design: Curaçao’s coastline features unique coral terraces that drop off rapidly into the deep ocean. Protecting a coastline must not come at the cost of the reef. Our primary goal is to minimize the physical and environmental footprint of the breakwater on the existing coral terrace. We are investigating how the choice of materials and the design of submerged surfaces can be optimized to avoid disrupting the local ecosystem, while exploring the potential for these structures to eventually host marine life.
• Stakeholder synergies: A technical solution only works if it serves the community. From tourism operators and divers to local government and residents, we are integrating the needs of the people of Curaçao into our design. We are asking: How can this infrastructure create value beyond just protection?

The big picture

The results from our site-specific analysis in Curaçao are showing that the local environment is the greatest teacher. By combining advanced wave modelling with respect for Curaçao’s social and biological context , we are working to determine if coastal defense can be transformed from a static barrier into an ecologically integrated system that supports the coastal environment.

Coastal protection should not be a wall between us and the ocean, but a bridge that supports both human safety and marine life.
