Analysis of Motion Response of Wind Turbine Platform Considering Different Heading Angles and Water Depths

Due to the occurrence of the overturning of the offshore wind turbine platform, this paper has conducted in-depth research on the offshore structure response of the wind turbine. Using the SESAM software, the wind turbine model was constructed to compare the motion response and structural response of the nose to the multi-floating wind power platform at different heading angles. Secondly, the magnitude of the motion response value of the floating platform of the fan under different water depths and the stress at the joint of the pontoon rod and the change of the RAO value are compared. The results show that the motion response and heading change of the fan platform are not obvious, and the water depth has a certain influence on it, and it is more obvious in shallow water. Therefore, in the future design of multi-floating wind power generation platform, the impact of wind turbine head steering changes on the structure can be neglected, but the effect of water depth on motion response and dynamic response should be integrated and considered to ensure that the platform can be safer.
