Abstract
The precast concrete floating structure for supporting a wind turbine comprises a precast SPAR-type monolithic platform made of concrete prestressed by means of active reinforcement bars. The structure is formed by a cylindrical section (13) finished at its lower end by a hemispheric cap (23) which acts as a flotation element and another cylindrical and/or frustoconical upper section (12), located above sea level, which acts as a support for the wind turbine. The structure is moored to the seabed by means of cable lines 20, through heavy ballasting elements or suction piles (16) capable of counteracting the vertical and horizontal components induced by the cables.
Claims7
A floating structure for supporting wind turbines or other elements, comprising a cylindrical lower section finished at a lower end thereof by a hemispheric cap, which contains ballast and acts as a flotation element, and an upper section, located above sea level, which acts as a support for a wind turbine or another element, wherein that said floating structure is a precast monolithic structure made of reinforced and prestressed concrete, with cylindrical and frustoconical sections having a total length comprised between 110 and 320 meters, comprising active reinforcement bars which have continuity through said hemispheric cap.
