FLOATING PRECAST-CONCRETE STRUCTURE FOR SUPPORTING A WIND TURBINE

摘要

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.
