FLOATING REINFORCED CONCRETE PLATFORM APPLICABLE TO THE MARINE WIND POWER SECTOR INDUSTRY

摘要

A solution for a floating reinforced concrete wind power platform for the mass production thereof, characterised by a geometric design endowing the concrete with a natural hydrostatic pre-stress, causing it to function under compaction. The structural response of the platform is improved by working in the most effective manner, and the appearance of fissures or cracks in the concrete is avoided, reducing the permeability thereof, and enabling a smaller quantity of steel rebars in the structure, also increasing the safety during operation. Furthermore, it has a system for anchoring the mooring lines to the structure in the form of a reinforced concrete lattice for the uniform distribution of the mooring tensions, minimising the pre-stress at the higher part of the platform and increasing the shear load area caused by the change in cross-section between the platform and the wind turbine generator tower. The geometric design further confers the versatility of being able to adopt low-draught SPAR-type solutions, semi-submersibles, barges or buoys, with the wind turbine generator installed centrally or off-centre on the structure, thus adapting to different requirements of draught or environmental or logistical requirements.
