The present invention provides an offshore wind turbine complete set, comprising a foundation, a tower column and a wind turbine set. The foundation utilizes a steel-concrete structure and comprises a plurality of tanks which are respectively provided with an opening; a lower end of the tower column is installed on the foundation; and the wind turbine set is installed on an upper end of the tower column. When the offshore wind turbine complete set floats on water, the openings of the plurality of tanks are under the water, and the tank is injected with air or water, and the buoyancy and uprighting force are provided by the plurality of tanks, so as to keep the entire structure in a vertical floating state consistent with the state of installation on the offshore site, but without external force on the water. The use of the offshore wind turbine complete set of the present invention eliminates the need for large hoisting machinery and transportation vessels in the offshore operation, the operation can be easily performed with high ratio of success, and greatly reduces the cost. Moreover, the technical solutions of the present invention have advantages such as low construction noise, small area of sea bed disturbance, and no pollutant leakage during the offshore operation and are environment-friendly.
