The wharf mooring scheme of the complete floating wind turbine and its dynamic response under environmental load are studied. Considering the steel-nylon composite cable and nonlinear fender, two wharf mooring schemes are designed, which are high-level mooring and low-level mooring. Considering the environmental loads of wind, wave and current, the dynamic response of the floating wind turbine moored on the wharf is calculated. The effects of mooring scheme, wave direction and spectral peak period on the motion of the floating wind turbine, engine room acceleration, cable tension, etc. are analyzed. The results show that: for the given environmental parameters, the motion extreme of each degree of freedom of the floating wind turbine is small, and the motion of the floating wind turbine at 90° wave direction is the most obvious; the high-level mooring is safer than the low-level mooring, and it is advantageous to use a higher mooring position. The study provides reference for the design of the wharf mooring scheme of the floating wind turbine system.
