FLOATING STRUCTURE FOR SUPPORTING A WIND TURBINE

摘要

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.

1. A floating structure for supporting a wind turbine, comprising:
a hollow precast monolithic concrete body having a hollow cylindrical lower section closed at a lower end thereof by a hemispheric cap and an upper section; active reinforcement members embedded in said precast monolithic concrete body; and a steel ring-shaped plate attached to an upper end of said upper section; wherein in use said hollow cylindrical lower section contains ballast and acts as a flotation element, and said upper section is located above sea level and acts as a support for a wind turbine; and wherein at least one of said active reinforcement members has opposite ends anchored to said steel ring-shaped plate by anchoring elements and an intermediate section which is embedded in the concrete and extends along the upper section, along the hollow cylindrical lower section, and has continuity within the hemispheric cap.
