Example Embodiment

[0042] The embodiment of the present invention includes the following steps:

[0043] (1) Initial positioning of the ship. After the ship hoisting the wind turbine, it travels to the wind turbine installation foundation and performs preliminary alignment with the wind turbine installation foundation. After the lower end of the wind turbine tower and the wind turbine foundation are roughly aligned, use the ship's pile leg positioning system 1 to insert the positioning pile into the seabed . Fix the hull to prevent the hull from shifting due to tide.

[0044] (2) Accurate positioning of fans. After the positioning pile is inserted into the seabed to achieve preliminary positioning, use the lateral movement device 5 of the leg positioning system 1 to adjust the left and right (lateral) movement of the wind turbine. The left and right movement stroke is about 2.4m and the movement speed is about 1m / min. ; Use the longitudinal adjuster 6 on the ship truss upper platform adjustment sy...

Abstract

The invention discloses a high-precision offshore wind turbine hoisting and mounting ship which comprises pile leg positioning systems, platform position-adjusting systems and a hoisting system. The pile leg positioning systems are arranged on a larboard and a starboard of the ship, each pile leg positioning system comprises a positioning pile, a lateral ship-moving device and an operating system, both the platform position-adjusting systems and the hoisting system are arranged on a truss of the ship, each platform position-adjusting system comprises an adjusting platform, a barrel holding device and a longitudinal adjuster, and the hoisting system comprises a hanging bracket and an electric winch. By the high-precision offshore wind turbine hoisting and mounting ship, transverse position and longitudinal position of a wind turbine and a wind turbine foundation can be accurately adjusted, quick one-step mounting of the whole offshore wind turbine can be realized, the problem of difficulty in mounting of the offshore wind turbine in an intertidal zone can be solved, and mounting of the wind turbine is low in construction difficulty and short in construction period.

Description

technical field [0001] The invention belongs to the technical field of marine engineering ship design, and in particular relates to a high-precision offshore fan hoisting ship. Background technique [0002] At present, there are two ways to install offshore wind turbines in my country: separate installation and integral installation. [0003] Split installation refers to the installation method of using a dedicated wind turbine installation ship to transport the various components of the wind turbine to the offshore wind farm, and then install the tower, engine room, and blades on the foundation of the wind turbine from bottom to top. [0004] Integral installation refers to the installation method of using a dedicated wind turbine hoisting ship to directly hoist the wind turbines on the wind turbine transport ship on the wind turbine foundation at one time in the offshore wind farm. [0005] The two methods have their own disadvantages. The split installation method is com...
