中文摘要：

以美国某可再生能源所的海上5MW风机为模型,综合风机塔柱的特点,利用Orca Flex建立了一种Spar型海上风机简化模型。通过对风机平台的不同风速工况环境载荷的计算,实现了对该风机系泊系统的水动力学分析,对比并分析了不同工况下风机锚泊系统系泊张力的变化。结合改变锚链上不同导缆孔的位置和布置形式,为海上风机浮式基础系泊系统的设计及优化提供依据。

英文摘要：

Based on the 5 MV wind turbine of a certain renewable energy institute in America and reference to the characteristics of the wind turbine tower,the model of a floating offshore wind turbine Spar platform mooring system was established by Orca Flex. By calculating the load of different wind speed conditions on the wind turbine,the hydrodynamic analysis of the wind turbine mooring system was researched and the mooring tension of the mooring system was analyzed in different load conditions. With the change of different fairlead position and different layout of the fairleads,the optimization design of the mooring system has been given.
