Each triangular floating platform is semi-submersible and anchored to the seabed. It consists of 3 vertical columns, interconnected/solidary to each other, and to one of them is attached the base of the wind turbine tower. The lateral distance of the platform (between the center of the columns) is about 50m. Its stability is reinforced by a system of gates that are filled with water at the base of the three columns, associated with a static and dynamic ballast system. This active ballast system moves the water between columns to compensate for the stresses caused by the wind thrust on the wind turbine. This moving ballast compensates for significant differences in wind speed and direction. Its purpose is to keep the wind turbine tower upright to optimize its performance.
