Description
Technical Field
The invention relates to the technical field of ship engineering, in particular to a device for preventing collision by traction when ships are close to each other, and a method for assisting the ship to pass the barge and lean against each other by using the device.
Background
When the ship performs offshore operation, fuel oil, fresh water, food and the like are indispensable materials. The materials are required to be placed in corresponding cabins for storage, the cabins of different types of ships are different in size and limited by the space of the ships, and the capacity of the cabins is limited, and the ship is characterized by engineering ships, official law enforcement ships and other ships which need to operate on the sea for a long time. The volume of the cabin and the amount of materials directly influence the sustainable working time of the ship in offshore operation, when the materials are consumed to a certain extent, the ship needs to return to the sea for replenishment, and then the operation is continued after the replenishment is completed. However, the ship needs to travel a lot of time, so that the operation of the ship has to be stopped, the working efficiency is seriously affected, and materials are continuously consumed in the travel process, so that the materials cannot be effectively utilized. For this reason, many vessels currently operating at sea choose to supplement the necessary supplies by means of special supply vessels. As shown in fig. 1 (a), the replenishment ship 101 needs to sail to the side of the working ship 102, and then can be connected with a connection hose or used for transporting materials by using a connection crane, but because of large seaborne storms, the ships are very easy to collide after approaching each other, thereby causing dangerous situations such as equipment damage, personnel injury, even turning of the ship, and the like; for this purpose, an inflatable rubber anti-collision ball 103 needs to be placed between two ships, and the ship is buffered by the anti-collision ball, so that collision is avoided. However, the use of the anti-collision ball still has some limitations which are difficult to overcome, for example, in order to improve the anti-collision performance, the anti-collision ball needs a larger size, but the weight of the anti-collision ball is increased, so that the anti-collision ball occupies a storage space and is difficult to retract and release; meanwhile, the anti-collision ball is fixedly arranged on the outer side of the replenishment ship, but the dimension and the appearance between the operation ship and the replenishment ship are different, and the two ships are difficult to stably achieve side by side; in addition, the rolling amplitude and frequency of the two vessels are completely different, and the anti-collision ball may not eliminate the mutual influence of the rolling motions between the two vessels, and may further aggravate the motion amplitude, so that the two vessels are unstably overturned, as shown in fig. 1 (b); moreover, the oversea operation is greatly affected by sea conditions, and the safe union of the oversea operation can be realized through the anti-collision ball only under three stages, but the time of calm of the sea is very short, so that the window period of the suitable operation is very short, and the working efficiency is poor.
