Floating structure for supporting a wind turbine

Abstract

The floating structure for supporting a wind turbine comprises a SPAR-type hollow precast monolithic body made of concrete prestressed by active reinforcement members having a cylindrical lower section (13) closed at its lower end by a hemispheric cap (18) which contains ballast (14) and acts as a flotation element and an upper section (12) located above sea level, which acts as a support for the wind turbine or other element. One or more of the active reinforcement members have opposite ends anchored to a steel ring-shaped plate (17) attached to an upper end of the upper section (12) and an intermediate section which has continuity within the hemispheric cap (18). The structure is preferably moored to the seabed by means of cable lines (15), through heavy weight elements (16) or suction piles capable of counteracting vertical and horizontal force components induced by the mooring lines.
