Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mooring method for mooring a ship to a buoy using a bow anchor chain as a mooring line.

[Conventional technology]

When mooring a ship to a buoy, the anchor chain at the bow of the ship is often used as a mooring line, and the method is as follows.

(1) Let out the anchor chain a little and secure the anchor to the bow side of the ship with a slip wire, rope, etc.

(2) Line up the anchor chain on the deck in the correct direction, take out all the sections, and remove and separate the anchor chain.

(3) Guide the second joint to the anchor hole, extend it outboard to the water surface, and use it as a mooring chain.

(4) Separately pull out the buoy shaft for mooring the mooring chain to the buoy from above the forecastle with its pin in place.

(5) While approaching the buoy and connecting the mooring chain to the buoy ring, use a separate hawser as a buoy rope to hold the hull to the buoy.
The hull is held by a buoy.

(6) Furthermore, in order to anchor the mooring anchor chain to the buoy ring, let out a ring rope to pull the end of the chain to the buoy from the bow on the opposite side of the mooring.

(7) In order to handle the above-mentioned ropes being let out from the ship, a buoy-retrieving work boat with approximately two deck crew members will proceed to the buoy.

(8) Once the buoy rope is connected to the buoy ring, move the buoy-retrieval boat away from the buoy and gently wind up the buoy rope. Pull the bow all the way to the buoy so that the anchor hole is as close to directly above the buoy as possible. and hold it.

(9) Bring the buoy removal work boat closer to the buoy again, dispatch a worker to the buoy, and connect the mooring anchor chain to the buoy ring.

(10) To do this, first pass the ring rope in (6) through the buoy ring and tie it to the end of the anchor chain, then wind the ring rope once on the ship to pull the anchor chain to the buoy ring and hold it there. Join with an inning shaft.

(11) Next, release the buoy rope and let out the required amount of mooring chain, and guide the ring rope through the buoy ring onto the deck of the ship and use it as a slip wire.

[Problem that the invention seeks to solve]

The following problems arose when mooring buoys using anchor chains:

(1) Many work procedures and preparations are required, resulting in a large loss of labor and time.

(2) Connecting the anchor chain on a buoy is a difficult task due to the large load and severe shaking of the buoy, but especially when the anchor hole is far from directly above the buoy, it is difficult to connect the anchor chain to the buoy. It was extremely difficult to pull the shuttle to the ground and lock it in place, and it was also a major safety issue.

[Means for solving problems]

In order to solve the above problems, the present invention fits a trolley to the end of the anchor chain, separately provides a guide rope winding winch, lets out a guide rope equipped with a stopper at the end from the winch, and connects the trolley. It is characterized by passing through the anchor chain loosely and locking it to the buoy ring, and then letting out the anchor chain and connecting it to the buoy.
This provides a buoy mooring method using a guide rope.

[Effect]

The trolley at the tip of the unrolled anchor chain moves along the guide rope, which guides the tip of the anchor chain to approach the buoy ring, making it easy to lock the anchor chain to the buoy ring. I can do it. In addition, without using the anchor chain as mentioned above,
If a windlass exclusively for mooring a buoy and a chain for mooring a buoy are separately installed and the mooring method using a guide rope of the present invention is used, the trouble of cutting off the anchor chain and the trouble of attaching and detaching the trolley will be eliminated. It can be made even easier.

〔Example〕

FIG. 1 shows the configuration of an embodiment according to the present invention.
FIG. In the figure, reference numeral 1 denotes a trolley attached to the tip of the second section of the anchor chain 2, and a guide rope 3 extends through a guide hole 1d of the trolley 1. At the tip of the guide rope 3, an eye 3a protected by an eye metal fitting is formed, and a stopper 4 is fixed to the base of the eye 3a. A shackle 5 is provided.

FIG. 2 is a front view showing the structure of the trolley 1. As shown in the figure, the trolley 1 can be divided into a member 1a and a member 1b around the hole into which the anchor chain 2 is inserted, and is fixed to an appropriate part of the anchor chain 2 by a tightening bolt 1c as necessary. In addition, a relatively large guide hole 1d is formed in the member 1b, through which the guide rope 3 passes freely.

Next, the effects of the present invention will be explained. FIGS. 3 and 4 are state diagrams showing the relationship between the ship and the buoy.
First, before the ship approaches the mooring buoy 6, remove the joining shafts of the first and second sections of the anchor chain, secure the anchor and the first section of the anchor chain to the ship's side, and then remove the joining shaft of the anchor chain 2. The trolley 1 is fixed to the tip of the second section with a tightening bolt 1c. The trolley 1 is provided with a guide rope 3 let out from a winch 8 and passed through a guide hole 1d. Next, the windlass 7 is driven to let out the anchor chain 2, and the anchor chain 2 is stopped once near the entrance of the hawse pipe 9 on the ship's deck, and the winch 8 is driven to let out only the guide rope 3, passing through the hawse pipe 9. and lower it. This state is shown in FIG.

The shackle 5 is then connected to the buoy ring 6a, thereby locking the guide rope 3 to the buoy 6. After that, while winding the guide rope 3 with the winch 8, operate the ship's engine to gradually bring the ship closer to the buoy so that the ship's hosepipe 9 is directly above the buoy 6, and then drive the windlass 7. When the anchor chain 2 is let out, the tip of the anchor chain 2 is held by the trolley 1 as shown in FIG. 4, and the trolley 1 is guided by the guide rope 3 and approaches the buoy ring 6a on the buoy 6. In this way,
When the tip of the anchor chain 2 reaches the buoy ring 6a, the drive of the windlass 7 is temporarily stopped, and the anchor chain 2 is connected to the buoy ring 6a using a separately provided buoy ring shackle. Thereafter, the windlass 7 and winch 8 are driven to let out the anchor chain 2 and guide rope 3 by the required amount, and the mooring work is completed. Perform the procedure in reverse to the above procedure for releasing the mooring, and after hoisting the anchor chain 2, drive the winch 8 to hoist the guide rope 3, and when the stopper 4 at the tip hits the trolley 1 fixed to the anchor chain 2, it will be hoisted. If you stop it, it will be in the storage state.

〔Effect of the invention〕

The present invention makes it easier to pull a heavy anchor chain to a buoy ring, which was extremely difficult in the past, and reduces work procedures, which not only reduces labor and time, but also has a great effect on safety. .
