Abstract: The vigorous development of wind power technology is a key pathway for many countries to promote low-carbon energy transformation and achieve "dual carbon" goals. As onshore and nearshore wind power resources reach saturation levels, it becomes an inevitable transition trend of wind power technologies from nearshore to deep-sea areas. The research and innovation of floating wind turbine(FOWT) platforms are key technologies to promote the development of offshore wind power in deep-sea areas. Based on an analysis of the current domestic and international development status of FOWT platforms, this paper discusses the theoretical foundations and commonly used numerical simulation tools for analyzing aerodynamic loads, hydrodynamic loads, and mooring calculations in FOWT platform analysis. The paper focuses on summarizing the characteristics of innovative technical approaches and design configurations that aim to improve structural stability and reduce costs in floating platform innovation. The current research status of FOWT platform optimization is summarized, and the existing problems and challenges in FOWT platform design are discussed, aiming to provide technical references and research ideas for researchers in related fields .
