Description

Anti-collision stabilizing device for ship berthing

Technical Field

The invention relates to the technical field of ships, in particular to an anti-collision stabilizing device for ship berthing.

Background

The ship berths and adopts the side position to berth the way mostly, berth the in-process, the hull needs to leave a distance of berth, the hull berths with berth shoreline parallel, after the ship berths, the both ends of the ship throw the tail cable and cable fall to the bank, draw the hawser and hang the hawser on the bollard cable pile by the manual work, the hawser is strained by the hawser on the ship finally, through the pulling force when the hawser, the pulling force will the ship translate to berth on the position, this kind of mode needs many people to cooperate and accomplish, comparatively hard, and efficiency is lower, and the ship can't stabilize the hull after berthing, the ship after berthing is influenced by the buoyancy of the sea water and rocks more easily, easily lead to the hull to bumping with the bank.

The Chinese invention patent CN112124497A discloses an anti-collision stabilizing device for berthing of a ship body, and relates to the technical field of ships.
