A recently granted patent (Publication Number: US11920559B2) discloses a floating platform designed for high-power wind turbines. The platform features a resistant base anchored to the seabed with mooring lines, maintaining a semi-submerged position. The platform includes a concrete substructure with a central cylinder and peripheral cylinders made of reinforced concrete. A metal superstructure supports the concrete substructure and connects to the wind turbine tower. The peripheral cylinders house ballast for flotation and stability, while the central cylinder accommodates a ballast water pumping system. The platform's design aims to prevent resonance with waves by incorporating specific features like elliptical holes in the lower slab and radial beams for structural support.

The patent also details a method for constructing the floating platform, involving pre-assembly of components in a submersible pontoon, concreting processes, and installation of the wind turbine components. The construction method is outlined in a dock-factory setup with specific areas for different stages of manufacturing. The method ensures the gradual sinking and ballasting of the platform while maintaining stability during the assembly process. Additionally, the installation of the metal superstructure is described, highlighting the use of a pontoon as a catamaran for support. The patented platform and construction method offer a novel approach to deploying high-power wind turbines in deep water, emphasizing stability, structural integrity, and efficient assembly processes.
