        How to Prevent the Fracture of Lost Anchor Chain

        来源:   作者: 发布时间:2019/01/03 浏览量:1323
        1. Strictly implement the operating rules for anchoring and the division of responsibilities for preventive overhaul. In peacetime, the anchor equipment and the anchor system should be thoroughly and meticulously inspected. When repairing a ship, the first section should be moved to the last section, which is by no means an interchange between the first section and the last section.
        2. The node marking of the chain should be painted regularly, and the last section should be painted yellow or red to warn.
        3. When installing the pin connecting the chain to the unloader, pay attention to whether it is suitable in size, smooth in surface and firm in installation. The green lead (soft lead) for filling pin holes should be extruded one by one, and should not be filled with soft lead several times, because such soft lead is easy to fall off one by one, resulting in loose pins and loss of chain anchor.
        4. Before anchoring, the captain shall inform the Chief Officer of the general intention and practice of anchoring and stipulate some emergency signals when the communication equipment fails. When the captain gives an anchor order, he shall first give the name of the ship in the telephone and then give an anchor order.

        5. When anchoring or down-stream anchoring in waters with unknown wind and current, one section (if water depth permits) should be thrown and towed until the ship is gradually straightened and then loosened or the chain is not very strenuous as seen from the tightness of the chain.
        6. When anchoring in overflow and gale, before loosening the chain to the desired length, slightly drive into the car to ease the retreat speed and prevent the brake from failing or breaking the anchor chain.
        7. In case of emergency anchorage in harbour, if the ship is fast, the loose chain should not be too much to prevent the brake from failing or breaking the chain. Generally, one section of anchor should be thrown first, and the anchor chain should be lengthened after the ship's speed has slowed down. Of course, another bow anchor can also be thrown to speed up the arrest of ship speed.
        8. When anchoring in narrow waters before and after anchoring, the general method of operation is to first throw the "back" anchor, but in order to make the "front" anchor at the right point, we have to throw the "back" anchor. After that, we still have to drive to maintain rudder efficiency and heading. Therefore, we have to release the brake and let the "back" anchor loose, but after seven sections of launching water, we have to start braking slowly. If the bridge does not control the ship's speed properly, the "rear" anchor will not stop until the eight sections are launched. The Chief Officer shall immediately advise the captain to drop the "front" anchor to slow down the ship's speed.
        9. Within the depth of 25M, the length of the partial anchor chain may not be taken into account before anchoring. When the water depth is 25 -- 50M, the anchor should be used to winch a section to about 5M above the seabed. When the water depth is over 50M, it is advisable to twist the anchor and chain until they reach the bottom of the sea. Whether the anchor is dropped to the seabed or the anchor is twisted to the seabed, the speed of the ship shall be controlled to a minimum or stop.
        10. It is not appropriate to anchor at a depth of more than 70M, because the weak horsepower of the anchor may have difficulties in lifting anchor at this depth. At this time, it is advisable to stagnate and avoid anchoring. If the anchor stays only for a short time in such deep water anchorage, try not to anchor.
        11. Avoid mooring in running water. If you have to mooring temporarily, you would prefer to close the short anchor chain and wait for the anchor to drive against the current, rather than break the chain by lengthening the anchor chain.

        12. Anchorage in drifting sand waters should be anchored every other day to avoid anchoring difficulties caused by deep burial of anchors in sand.
