海上半潜式风电机组湿拖方案优化

Optimization of Wet Towing for Semi-Submersible Floating Offshore Wind Turbine

为了研究半潜式风电机组拖航优化方案和分析方法,基于三维势流理论的数值计算分析方法和有限元分析法,利用多体耦合分析,进一步开展针对海上漂浮式风电机组在不同安装阶段下的拖航方案以及该方案对于优化被拖风电平台运动和拖缆稳定性的研究。结果表明,当风机平台后方配置辅助拖轮的情况下,辅助拖轮可减小风机平台的横向运动及艏摇运动,形成了不同安装阶段拖航方案全耦合分析方法。研究成果可为海上半潜式风电机组湿拖作业提供一定参考。

The optimize the dynamic response of the semi-submersible wind turbine platform during the wet towing procedure is carried out.Moreover,the numerical stimulation and analysis method of the three-dimensional potential flow theory and finite element analysis is implemented by commercial software combined with the multi-body coupling analysis.The wet towing schemes of different installation strategies,namely platform only or platform integrated with wind turbine,are carried out.Furthermore,the hydrodynamic performance and stability of the towed wind turbine platform are further studied.The results of this study preliminarily show that the auxiliary towboats which are located behind the wind turbine platform can effectively reduce amplitude of the sway and yaw motion of the platform.A reliable reference for wet towing operations of the offshore semi-submersible wind turbines is provided.
