[0002] When maintaining offshore wind turbines, the ship needs to be docked near the wind turbines. When the ship is docked, the ship needs to use the docking parts to cushion the impact of the hull on the wind turbine components.

[0003] An existing patent discloses a ship-mooring energy absorber (CN 215098156 U) that is easy to quickly position and install. The invention comprises an energy absorber body and a positioning device. The surface of the energy absorber body is provided with four circular holes. The surface of the energy absorber body is provided with a positioning device. The positioning device comprises two cartridges. The surfaces of the cartridges are slidably connected to the circular holes. The inner walls of the cartridges are slidably connected to fixing rods.

The vertical reversing bracket 501, the horizontal reversing bracket 503, the corner reversing bracket 504 and the U-turn reversing bracket 505 are collectively referred to as reversing brackets. The reversing bracket includes a support plate 512 and a reversing shaft 513 fixedly installed on the surface of the support plate 512, and the outer surface of the reversing shaft 513 is rotatably connected to the reversing wheel 502, and the rear end of the support plate 512, the rear end of the connecting sleeve 511 and the rear end of the mounting plate 1 are all fixedly installed with a connecting member 6 for connecting to the platform.
