To ensure the safety and efficiency of offshore wind power operations, a composite bucket offshore wind turbine installation vessel was developed. Firstly, the current situation and problems of offshore wind power installation ships were described, and the design idea of a one-step offshore wind power installation vessel was clarified. Then, the key technologies such as the application conditions, the vessel shape design, the wind turbine fixing method, the wind turbine fixing steps, the internal air pressure and the draft of the wind turbine base, and the truss clamping were described. The wind turbine has been successfully developed and put into use, and its safety and reliability have been tested in actual water operation.
