The invention relates to a floating platform for supporting generators of wind, wave and marine current power, which has a generally disc-like shape with a circular or polygonal perimeter, the size of the platform being optimised, considerably minimising the weight and, thereby, the production costs thereof, in addition to other related problems. The platform prevents the possibility of being able to resonate with the movement of the sea waves, preventing the installed devices from becoming damaged or falling over, and does not exceed the maximum inclination acceptable for generators of wind, wave or marine current power. In addition, the platform can withstand the largest possible waves, owing to a relationship between the height or support (13) of the platform and the diameter (14) thereof, in a ratio of between 0.06 and 0.35.

YAWING BUOY MAST FOR FLOATING OFFSHORE WIND TURBINES

NºPublicación: EP4007851A1 08/06/2022

Solicitante:

AQUANTIS INC [US]

KR_20220081329_PA

Resumen de: WO2021022250A1

The present invention provides a novel, floating, offshore wind turbine (FOWT) structure, referred to as a yawing buoy mast (YBM) structure. The YBM platform vertically combines a submerged spar buoy with outrigger legs and a mast on which a wind turbine nacelle is mounted. Compared to a conventional spar buoy wind turbine, weight is significantly reduced by optimizing how loads are borne and reacted by the floating structure. The mass of the YBM platform is reduced relative to the energy captured by the turbine resulting in a reduction in the cost of energy (COE). Platform load dynamics are coupled with the dynamics of the wind turbine by integration of the YBM platform and turbine controllers.
