Background
At present, large and medium-sized passenger ships, particularly mail ships, carry a lot of passengers, and the number of passengers and crew is many thousands of people. According to the relevant international regulations, a passenger ship must be staffed to deploy a lifeboat raft. However, even if large-capacity lifeboats are selected, the number of lifeboats required in the passenger ship is still large. Therefore, modern passenger ship designs increasingly adopt schemes of externally arranging lifeboats.
Compared with the traditional scheme of arranging the lifeboat in the passenger ship body, the scheme of externally arranging the lifeboat does not occupy a large amount of valuable internal space of the ship body, and is more favorable for arrangement of passenger ship cabins, public spaces, places and the like. However, after the scheme that the lifeboat is externally arranged is adopted, the lifeboat protrudes out of the main hull and is not protected by the hull shell any more, so that the lifeboat is more easily impacted by waves. In particular, ocean-going passenger ships inevitably encounter severe weather such as storms. When a storm occurs, a passenger ship sails by using top waves, and a lifeboat positioned at the head part of the ship is easily impacted by the top waves, so that the structure is damaged, and even the hull falls off.
Therefore, how to design a wave-absorbing protection device for the wave-absorbing impact of the external lifeboat, reduce the wave-absorbing impact borne by the external lifeboat, and improve the safety of the external lifeboat of the passenger ship under severe sea conditions becomes a technical problem to be solved urgently.
