AI Technical Summary

Technical Problem

Existing floating platforms are costly to build and prone to damage and capsizing in offshore wind power generation, and current technologies have not been able to effectively address these issues.

Method used

The design employs a combination of steel frame and concrete structure, including central support, main beam, secondary beam, pontoons and floating arms. The steel frame bears the main longitudinal shear force and wind turbine load, while the concrete pontoons and floating arms disperse the lateral stress. The stability is enhanced by the addition of anti-corrosion layers, motion sensors, and other features.

Benefits of technology

This effectively reduced the overall construction cost, decreased the risk of localized damage, and improved the overall stability and service life of the floating platform.

Abstract

This application provides a floating platform for offshore wind turbines, comprising at least: a foundation frame, multiple pontoons, and multiple floating arms; wherein the foundation frame is a steel frame, and the pontoons and floating arms are concrete structures; the foundation frame includes at least: a central support member, main beams, and secondary beams; the central support member is used to fix the wind turbine; multiple main beams are radially connected to the outer edge of the central support member; multiple secondary beams are arranged transversely on the main beams; a fixing member is also connected to the end of the main beam; the main beam is inserted into and fixed within the floating arm; the fixing member is fitted with the pontoons; and a compartment is also provided inside the pontoons. The floating platform for offshore wind turbines based on the above structure can effectively reduce overall costs and reduce the risk of localized damage to the floating platform, thereby improving overall stability.
