Description

Port ship anti-collision device

Technical Field

Background

A ship is a generic term for various ships, and is a vehicle that travels or parks in a water area for transportation or work. The ship has the advantages of floating property, stability and sinking resistance.

It is very important that ships stop safely in port. In general, a ship is mainly parked in three modes, namely a bow-first mode, a stern-first mode and a parallel mode. Wherein, the common small and medium-sized ships generally adopt a mooring mode that the bow of the upwind top flow ship leans against first, under the condition, the ships can finish mooring by self-anchored equipment without the assistance of a tug; the large ship is heavy, so that the large ship is difficult to berth only by self equipment, and generally needs to berth in parallel under the assistance of front and rear tugs; when the loading and unloading bridge plate of the roll-on passenger cargo ship is installed at the stern, a berthing mode that the stern leans first is generally adopted, mainly for the purposes of convenient loading and unloading and relatively flexible operation, the loading and unloading bridge plate is arranged at the bow and the stern of the existing passenger cargo ship, so the berthing mode is gradually replaced by a berthing mode that the bow leans first and the stern leans first.

The ship is composed of a plurality of parts, and the devices for assisting the ship to stop mainly comprise anchor equipment, mooring equipment, anti-collision equipment or buffer equipment and the like. In the process of berthing at a port, the ship has the drifting property in a water body, and the ship is easy to collide with the port when berthing, so that anti-collision equipment or buffering equipment is required to be arranged at the port so as to avoid collision of the ship to the port in the process of berthing, and the ship structure at the bow and the berthing port can be damaged.
