VESSEL AND METHOD FOR TRANSPORTING AND HOISTING THE OFFSHORE WIND TURBINE GENERATOR SYSTEM

A vessel for transporting and hoisting offshore wind turbine comprises a hull (7), a plurality of fixing brackets (1), first sliding rails (31), second sliding rails (32), a buffer device (5), rotary cranes (6) and winch devices(4). A U-shaped opening is provided at the stern of the hull (7) for a wind turbine (8) to pass through. The fixing brackets (1) are arranged in two rows in parallel, the bottom of which are fixed onto the deck in the hull. The first sliding rails (31) are installed on the top of each row of the fixing brackets (1). The second sliding rails (32) are installed on the inner side of the two rows of the fixing brackets (1) on the deck in the hull. The second sliding rails (32) are in parallel with the first sliding rails (31). A hanging beam (2) slidably matched with the first sliding rails (31) is installed on the body of the wind turbine (8). The buffer device (5) is fixed to the bottom of the wind turbine (8), and is slidably matched with the second sliding rails (32). The rotary cranes (6) are fixed on the top of two sides of the U-shaped opening. The winch devices (4) is installed on the stern of the hull. An offshore wind turbine transporting and hoisting method using a vessel for transporting and hoisting offshore wind turbine is also disclosed. The invention enables the wind turbine to be integrally transported and hoisted. Figure 1 is the representative figure.
