The present invention relates to a solution for a floating wind platform made of reinforced concrete for mass production, characterized by a geometric design providing a hydrostatic natural prestressing to the concrete, causing it to work under compression. The structural response of the platform for working in the most effective mode is improved, and the occurrence of fractures or cracks in the concrete is prevented, which reduces permeability and allows for reducing the rebar to be contained in the structure, also increasing operational safety. Furthermore, the invention has a system for anchoring the mooring lines to the structure in the form of a truss made of reinforced concrete which evenly distributes mooring stresses, minimizing prestressing in the high area of the platform, and increasing the area for distributing shear forces due to the change in section between the platform and the tower of the wind turbine. The geometric design furthermore confers the versatility of being able to adopt low draft SPAR, semi-submersible, barge, or buoy solutions, with the wind turbine being installed such that it is centered or off-center on the structure, thereby being adapted to different draft requirements or environmental and logistics conditions.
