Abstract

In order to solve the problem of large motion responses of the existing floating wind turbines under the action of wind and waves, a new type of semi-submersible platform with round table-shaped buoy is proposed. Based on FAST coupling hydrodynamics, aerodynamics and mooring system and other physical fields, combined with the frequency domain parameters calculated by hydrodynamics software AQWA, the dynamic responses of the floating wind turbine under different wind conditions are analyzed, and compared with OC4-DeepCwind floating wind turbine under rated wind condition. The analysis results show that different wind speeds have obvious influence on the surge, pitch and yaw motions of the floating wind turbine, but have little influence on the heave motion. Compared with the OC4 floating wind turbine, the pitch and roll responses of the new floating wind turbine are obviously reduced under various wind conditions, and have good stability.

Key words
