南海环境下半潜式风机系泊系统布置方案对比研究OA

The mooring system serves as a key component ensuring the positional stability and structural safety of floating offshore wind turbines.Its dynamic behavior directly affects the power generation efficiency and operational reliability of the entire system.This study focuses on the DTU 10 MW offshore wind turbine and investigates the mooring performance of its semi-submersible floating foundation under the environmental conditions typical of the South China Sea.A coupled numerical model was established using FAST program and TurbSim module to simulate the interaction between turbulent wind and irregular waves.The accuracy of the wind-platform-mooring coupling method was validated through free-decay tests.Subsequently,dynamic analyses under different operating conditions were performed to compare three mooring configurations:3×1,3×2,and 3×3.The findings of this research provide technical guidance for the mooring design of floating wind turbines in the South China Sea and similar deep-water regions.
