Description

Dock ferry docking device for large ship

Technical Field

The invention belongs to the field of water transportation traffic, and particularly relates to a docking device for a ferry of a large ship.

Background

As is well known, berthing refers to the berthing of vessels at a quay or port location, with current berthing of vessels being primarily the continuous or intermittent securement of a plurality of scrap tires, or rubber, on the quay berthing side walls as anti-collision shock absorbing means.

Because the ship still is in a motion state in the berthing process, when the shock absorption device collides, a reaction force exists, the ship can be pushed away again, and the whole motion state presents the inclined motion track of waves.

For those large vessels, simple anti-collision shock absorbing devices cannot meet the demand, and this approach may cause problems of hull damage to the vessel due to excessive impact forces when berthing.

Port sludge is a sediment deposition phenomenon generated in a channel and a port pool of a harbor, and port sludge can cause reduced water depth to prevent navigation, and ports with serious sludge become even waste ports.
