Floating offshore wind turbine is generally suitable for deep sea areas (water depths greater than 60 m). Because the wind power in deep sea areas is more powerful and continuous than that in offshore areas, the wind energy utilization of floating wind turbines is higher than that of fixed offshore wind turbines. The installation of floating wind power generators is not restricted by the seabed and can maximize the utilization of offshore wind resources, which is conducive to the continuous provision of stable electric energy. At present, floating wind power generators have been applied in Nordic and Japan, and Hywind, the first commercialized project in the world, has been put into operation in 2017.In addition, nearly 80% of the world's exploitable wind resources are concentrated in the deep sea area, and the future application prospects of floating wind power generation units are promising. Domestic research on floating wind turbine is still in the preliminary stage in general, and there is no prototype installation and application at present. However, China has a perfect industrial chain, and has accumulated technology in the related marine industry fields such as floating platform research and development, complete equipment manufacturing, etc., so there are no great restrictions on the development of floating wind power generation technology. In this paper, the market status of floating wind power generator and the structure form of foundation and mooring of floating wind power generator are introduced, which can provide reference for domestic practitioners.
