摘　　要：利用WADAM程序进行三维辐射/衍射频域分析计算,计算时域分析所需的相关水动力系数,如附加质量、辐射阻尼、一阶/二阶波浪力传递函数和RAO等。优化设计一套适用于浅水的悬链式系泊系统,利用ORCAFLEX开展对大型半潜漂浮式风机在50年一遇极端工况下风浪流耦合环境条件模拟。分析大型半潜浮式风机在极端工况下完整系泊和考虑系泊失效(单缆破断)情况下的运动响应、塔顶加速度及锚链设计张力等风机关键控制参数。结果表明,该大型半潜漂浮式风机稳定性好,完整系泊和单缆破断运动和系泊性能表现优异,风机关键控制参数均能满足50年一遇极端工况的设计值要求。Three-dimensional radiation/diffraction frequency domain analysis was conducted using the WADAM program to calculate the relevant hydrodynamic coefficients required for time domain analysis,such as added mass,radiation damping,first-order and second-order wave force transfer function,and response amplitude operator(RAO).A catenary mooring system suitable for shallow water was optimized and designed.The ORCAFLEX was used to simulate the coupled wind,wave and current environment conditions of a large semi-submersible floating wind turbine under extreme conditions once in 50 years.The key control parameters of large semi-submersible floating wind turbine under extreme conditions such as complete mooring and mooring failure,tower top acceleration and mooring lines design tension were analyzed.The results showed that the large semi-submersible floating wind turbine has good stability,excellent performance of complete mooring and single chain breaking motion and mooring performance,and the key control parameters of the wind turbine can meet the design requirements of extreme conditions in 50 years.
