Offshore wind turbine floating transportation and installation system

Abstract

The invention discloses an offshore wind turbine floating transportation and installation system, which relates to the field of floating wind turbines, and comprises a buoyancy base, an operation and maintenance platform and tugboats, wherein the buoyancy base is arranged at the bottom of a fan tower, a ballast water sump is arranged in the buoyancy base, a submersible pump and a water level sensor are arranged in the ballast water sump, and the submersible pump is communicated with a water inlet and a water outlet of the ballast water sump; a tower tube groove matched with the side wall of a fan tower tube is formed in the middle of an upper layer building of the operation and maintenance platform, a universal joint of the fan tower tube and a hoop lantern ring connected with the universal joint are arranged at the rear end of the tower tube groove, and a plurality of binding pieces are arranged at the front end of the tower tube groove. The three tugboats are connected to the two sides of the buoyancy base and the operation and maintenance platform through pull ropes correspondingly. The complete offshore wind turbine can be dragged to an offshore wind field in a floating mode, the blades are installed on the hub on the top of the wind turbine tower barrel, then the wind turbine tower barrel is vertically installed in a floating mode through the universal joint and the crane, the whole process is very simple and convenient, the transportation and installation efficiency of the offshore floating wind turbine can be remarkably improved, and expenditure is greatly reduced.

Description

technical field [0001] The invention relates to the field of floating wind turbines, in particular to a floating transportation and installation system for offshore wind turbines. Background technique [0002] Offshore floating wind turbines include wind turbine towers, buoyancy bases, monopiles, nacelles, and blades arranged on hubs. The overall volume and weight are very large, and the wind turbine towers are nearly 1,000 tons. The current installation process for this type of wind turbine is to use a large operation and maintenance ship to dismantle it into several major components, transport it from the workshop to the offshore wind farm, and then assemble it on the sea surface. The transportation and installation costs are very high, and the requirements for the operation and maintenance ship are extremely high. It is high and requires the cooperation of thousands of tons of cranes, and the installation process is very difficult due to the oscillation of sea waves. Co...
