[0001] The invention relates to the technical field of ship mooring, and in particular to a device for mooring ships. Background Art

[0002] When a ship needs to anchor for a long time, it usually sails into a dock or a specific offshore facility, and then uses cables to fasten the mooring bollards on the dock and the bollards on the ship to moor the ship at the dock, and confine the ship to a certain safety range to meet the docking requirements; at the same time, in order to improve the stability of the mooring, a certain number of bollards need to be set at the bow and stern of the ship, and equipped with a corresponding number of cables.

[0003] At present, the mooring operation of ship cables mainly relies on the staff. Under normal circumstances, the staff can stably perform the mooring work using the mooring equipment equipped on the ship. If the dock or sea area where the ship is docked has obvious tidal phenomena, the staff on the ship need to constantly adjust the mooring cables according to the tides to meet the mooring and docking requirements; otherwise, the mooring structures such as cables, mooring piles and bollards are likely to be damaged, resulting in damage to the ship. The repeated adjustment process of the mooring cables is extremely troublesome, time-consuming and labor-intensive. In extreme weather, it may even seriously affect the work safety of the staff.
