DemoSATH Lab is part of DemoSATH, a pioneering offshore wind energy project led by Saitec in collaboration with RWE and The Kansai Electric Power Co. This initiative successfully deployed Spain’s first floating wind turbine, capable of generating power for 2,500 households.
Located at the BiMEP testing platform, 2 miles off the Basque coast, the 2 MW DemoSATH turbine is a significant step forward in floating wind technology. The project not only validates the SATH (Swing Around Twin Hull) floating platform design but also integrates extensive research on environmental impact, biodiversity promotion, and coexistence with marine activities.
Innovative Initiatives for Sustainable Offshore Wind Development
To ensure the harmonious coexistence of offshore wind farms with marine ecosystems and local communities, DemoSATH Lab has implemented a series of groundbreaking initiatives, some supported by RWE, including:
Promoting Biodiversity with Hybrid Blue-Grey Infrastructure
The SATH Reef Unit is a nature-based solution (NbS) designed to enhance marine biodiversity and promote sustainable aquaculture. Constructed using recycled wind turbine blades and mollusk shells, this innovative artificial reef provides a vital habitat for marine species while also serving as a protective structure for subsea cables.
Sustainable Barnacle Cultivation & Multitrophic Aquaculture
DemoSATH Lab, in collaboration with local fishers and aquaculture experts, is pioneering sustainable barnacle farming methods with the goal of industrial-scale deployment on future floating platforms. The initiative also includes the cultivation of oysters, clams, mussels, and seaweed, contributing to marine food production while enhancing biodiversity.
Experimental Fisheries & Species Restoration
By working closely with local fishing communities and BiMEP, DemoSATH Lab is testing low-impact fishing techniques, including surface longlines and traps in wind farm areas. Additionally, efforts are underway to restore commercially valuable species such as lobster, octopus, sea urchins, and spider crabs, supporting marine resource sustainability and local economies.
Advanced Environmental Monitoring & Marine Research
To understand and mitigate the ecological impact of floating wind farms, DemoSATH Lab has deployed state-of-the-art environmental monitoring technologies, ensuring that offshore renewable energy development aligns with marine conservation efforts.
A Commitment to a Sustainable Energy Transition
The energy transition must go hand in hand with environmental protection and community engagement. DemoSATH Lab exemplifies how floating wind energy can integrate innovative solutions that support marine biodiversity, local economies, and sustainable development. By fostering collaboration and pioneering research, the initiative sets a new benchmark for responsible offshore wind projects, demonstrating that renewable energy and ocean conservation can thrive together.
