Abstract: With the gradual increase of renewable and clean energy demand in China, the development of onshore wind energy tends to be saturated. It is an inevitable trend for wind power to be applied in offshore and deep-sea areas. The development and engineering application of floating foundation structures are the key technical measures to promote this trend. This paper comprehensively reviews the applicable depth range, basic types, mooring system, fabrication and installation of floating foundation structure for offshore wind turbines, which aims to provide technical references for the development of wind power in offshore and deep-sea areas.
