The testing campaign at the IHCantabria facilities of the SATH platform, within the DemoSATH Project, ends


After five years of development, SATH (which stands for ‘Swinging Around Twin Hull’) aims to be a revolutionary solution for installation of wind turbines in intermediate to deep waters, thanks to its adaptability to a wide range of turbine sizes and power, together with an innovative strategy regarding its construction and installation.

Saitec Offshore Technologies —the company which conceived the solution—, aims at entering the offshore wind market in locations from intermediate (30 m) to deep waters, where the SATH platform is highly competitive thanks to its low construction and installation costs. SATH technology allows a greater standardization, since its precast and prestressed concrete structure is easily scalable. Unlike other solutions which require expensive and complex steel manufacturing techniques, concrete allows also local industries to take part in the manufacturing process.

One of the objectives of DemoSATH project was to validate the performance of the SATH platform. Saitec Offshore just completed a new test campaign, aimed at the future installation of a 2 MW wind turbine in BiMEP, the open-sea test site in the Basque Country.

This 1:35 scale test campaign was performed in the facilities of IHCantabria, and a wide variety of metocean conditions were simulated, including waves, currents and wind, implementing the real conditions of the wind turbine through a multi-fan system, taking into account turbulent wind and the effects of the control system. This way, the SATH floating solution was analyzed under the most demandingsea states, and proven to be an excellent technology even in the most unfavorable conditions.

The results obtained have been incorporated to the technological development of Saitec Offshore Technologies and they will serve as a basis for design optimization and validation. This optimization is focused on further cost reduction of SATH platform, even in comparison with fixed offshore wind foundations.

These improvements, together with the installation of the 2 MW prototype in BiMEP, will help SATH achieve the necessary maturity for future commercial launching of this technology.



The project has obtained a grant from SODERCAN of €656,387.36 in its final phase through the call for proposals of the I+C=+C 2016 PROGRAMME - SUPPORT FOR R+D PROJECTS IN COOPERATION IN MARINE RENEWABLE ENERGIES.
