Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention can be used to transport ships to quays or other locations. The present invention relates to a method for mooring a ship and a device suitable for carrying out the method.

[Conventional technology and its problems]

Conventionally, when mooring a ship to a quay or another ship, the following steps are performed.

■Place two to three people in the fare department and the stern, and place a mooring manager in the wheelhouse in the center of the ship.When approaching the other vessel (or quay) to which you wish to moor, first start from the fare department side. A thin rope tied to the end of a mooring line (wire rope, etc.) is thrown to the other party.

■On the other ship's ship, the worker pulls this rope to pull the mooring line together, and ties this mooring line to the own ship's bit (or bollard).

■ Wind up a predetermined amount of the mooring line with the mooring winch to complete the work on the hull side.

■Similar work is carried out on the stern part, completing a series of mooring work (as the ship becomes larger, the center part is also moored with mooring ropes in addition to the stern)0 However, such conventional methods Mooring work requires a lot of manpower and time, and the wire robes normally used as mooring lines often break.
The problem is that the mooring work itself is extremely dangerous.

The present invention has been made in view of these problems, and it is an object of the present invention to provide a method of mooring a ship safely and appropriately with less manpower, and a device suitable for carrying out the method.

[Structure and Examples of the Invention]

For this reason, in the present invention, the mooring cable is suspended in a slack state via a davit extending outward from the berth, and after hooking the bit of the other berth to the slack mooring cable, The basic feature is to wind up the mooring line (':)'), lower the upper end of the hoisted mooring line along the davit, and moor the ship, and such a method is preferably carried out. As a device for this purpose, there is a davit that is rotatably provided on the side of the ship so that it can extend outward, a winding winch that can be raised and lowered along the davit, and a wire winding winch that winds the wire at the tip.
