Abstract

To address the problem of poor wave resistance of existing offshore floating wind turbines, a new type of semi-submersible platform with truncated-cone-type upper pontoons is proposed by combining the characteristics of offshore wind turbine semi-submersible floating platforms. Based on the coupled hydrodynamic, aerodynamic, and mooring force physical fields of FAST, the surge, heave, pitch, and yaw motions responses of the floating wind turbine under different wave heights and periods are obtained, and the mooring line tension responses are also obtained; and compare the dynamic response of the new semi-submersible platform with the OC4-DeepCwind platform at six degrees of freedom. The results show that different wave conditions have obvious effects on the heave and pitch motions of the new floating wind turbine, and fewer effects on the surge and yaw motions; the tensegrity response of the mooring system is more affected by the wave conditions; compared with the OC4-DeepCwind floating wind turbine, the pitch and roll response of the new floating wind turbine has been significantly reduced and has good stability.
