摘　　要：以DTU 10 MW风电机组以及OO-Star半潜式平台为对象,提出一种两分叉系泊系统,基于OPENFAST软件在50年一遇极端工况下建模仿真,对比采用两分叉系泊系统平台运动响应及系泊张力的变化,并研究其分叉点位置的影响。结果表明,新型两分叉系泊系统使得平台的纵荡、纵摇、艏摇幅值分别减小32.9%、29.4%和39.1%,很大程度上提升了风电机组的稳定性。此外,平台的系泊张力均值降低为原来的23.4%,更能保证漂浮式平台在极端工况下的生存能力。A bifurcated mooring system is proposed for the DTU 10 MW wind turbine and the OO-Star semi-submersible platform.Based on the OPENFAST software,the system is modeled and simulated under a 50-year extreme condition,and the changes in platform motion response and mooring tension are compared with which of the original system.The effect of the bifurcation point position is also studied.The results show that the new bifurcated mooring system reduces the platform's heave,pitch,and yaw amplitudes by 32.9%,29.4%,and 39.1%,respectively,greatly enhancing the stability of the wind turbine.In addition,the mean mooring tension of the platform is reduced by 23.4%,which further ensures the survival capability of the floating platform under extreme conditions.
