Abstract

INTRODUCTION: Because of its versatility and adaptability, floating wind turbine platforms have emerged as the go-to foundation type for deep sea wind power as offshore wind power production steadily expands into deeper waters. OBJECTIVES: But the floating platform's six-degree-of-freedom motion and the anchor chain system's mechanical reaction to the combined force of wind, wave, and current are incredibly intricate, and this directly affects the platform's stability and safety. METHODS: Under various wind, wave, flow incidence angle, and chain length conditions, the platform's six-degree-of-freedom motion characteristics and anchor chain tension distribution are carefully studied using potential flow theory, the finite element method, and the fluid-structure coupling model. The numerical simulation combined JONSWAP wave spectrum and NPD wind spectrum to conduct multi-condition analysis. RESULTS: the results show that the incidence Angle and anchor chain configuration have significant effects on the dynamic response of platform pitching and pitching. CONCLUSION: This paper deeply discusses the platform motion response under the broken anchor chain, and puts forward the corresponding optimal design scheme.
