Australian engineering services group, Worley, has completed the accessibility design assessment for a 2-MW floating wind turbine that will be deployed off the Basque coast in northern Spain. The DemoSATH turbine has been developed by Spanish renewable energy company, Saitec Offshore Technologies, and construction of the pilot plant is due to begin in the Port of Bilbao during the third quarter of this year.
The project has been set up to test the first floating concrete design using Swinging Around Twin Hull (SATH) technology. With financial support from Germany’s RWE Renewables, the SATH concept will be tested under real-life conditions, collecting data relating to construction, operation, and maintenance of the floating unit. The turbine, which will supply sufficient renewable electricity to power about 2,000 homes, will start a two-year operating phase once it is installed and connected.
Worley’s consultancy services have included guidance on access, inspection, boat landings and turret access design requirements. The company also advised on access materials, handling scenarios in different weather conditions, and human factors including health, safety, security and environment requirements. David Carrascosa, Saitec Offshore’s chief technology officer, commented: “Maximising availability of floating wind is one of our ultimate goals and having the opportunity to collaborate with Worley and taking advantage from their know-how and expertise serves as a stepping-stone towards safe and optimal operation of SATH platforms.”
