The quasi-cylindrical foundation is expected to help make it possible to drive down construction and installation costs of offshore wind turbines to about €1m ($1.32m) per MW, making it competitive with jackets in water depths of 35 metres and deeper.
Scaled for mega-class turbines of up to 10MW, the “surface floater” would have a diameter of some 40 metres and a draught of less than ten metres.
