Abstract: Vigorously develop wind power generation technology is the core path for the country to promote the low-carbon transformation of energy and realize the "dual-carbon" goal. With the gradual saturation of the development of onshore wind power and offshore wind power resources, wind power development from the near-shore to the deep and distant sea is the inevitable trend of the future development of the wind power industry. The research and development and optimization of floating offshore wind turbine (FOWT) platform is the key to promote the development of offshore wind power to far and deep sea area. Based on the analysis of the current development status of FOWT platforms at home and abroad, this paper further analyzes the current research status of aerodynamic loads, hydrodynamic loads, mooring systems, coupling analysis methods and commonly used numerical simulation tools in the design of FOWT platforms, and focuses on sorting out the key technological ideas and constitutive features of floating platforms that are driven by the enhancement of structural stability and the reduction of costs. By summarizing the current research status of FOWT platform optimization, we look forward to the problems and challenges in the design of FOWT platforms, with a view to providing technical references for researchers in related fields.
