A floating type aquatic support apparatus according to the present invention comprises: a ball, a floating means having a floating portion which floats in water and supports the ball such that the ball can rotate; a support of which one end is exposed above the water so that a structure can be mounted thereto, and the other end is heavier than the one end so as to be erected vertically in the water, and which is coupled to the ball. The ball has a guide groove along the circumferential surface through which the support passes. In addition, the floating means further includes a restraining protrusion inserted into the guide groove to restrict the rotation of the ball around the axis of the support, and a fixing member which mounts the restraining protrusion to the floating portion. According to the present invention, the restraining protrusion is inserted into the guide groove of the ball so as to prevent the support coupled to the ball from rotating about the central axis thereof. Therefore, when a wind turbine is mounted on the support, it is possible to prevent the axis of the wind turbine from being rotated by the wind.

SEAPLACE S L [ES]

ES_2876053_PA

Resumen de: WO2021224525A1

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.
