The maximum number of people carried by the large-sized lifeboats and rafts is 150, the lifeboats and rafts are displayed in two layers on two sides of the ship board of the cruise ship, the occupied area is large, and the lifeboats and rafts are quite spectacular. The large-scale lifting equipment is used for fixing and releasing large load, so that the ship is comfortable, the ship is stably driven to the sea surface, passengers are safely separated from the sea without touching water, and the high-end customer group feels safe and high.

However, the occurrence of marine perils is unpredictable, the accident causes are various, the ship inclines to one side due to the numerous post-ship accidents in the longitudinal history, half of the life-saving equipment is lost and cannot be utilized, and only half of the equipment is limited by the fixed bearing capacity and the shape of the equipment, so that the climbing of more people cannot be achieved. The inflatable life-saving appliance is mostly soft, and has weak wind and wave resistance and tearing resistance, because the external stress parts of the inflatable life-saving appliance are made of the same material as the air bag air-tight layer and are integrated, the rubber of the inflatable life-saving appliance is attached to the nylon layer cloth in a combined mode, and the risk of leakage and gas leakage caused by overlarge tearing force of an acting point is great.

And because of the fire of the cabin which is often accompanied by accidents, the fire of the cargo inspection wheel and the fishing boat reaches 50%, so that the release efficiency of the life saving equipment is greatly reduced after the ship loses power and loses energy, the captain and the crew are forced to be almost fully put on the manpower or the standby power supply to release the rescue raft, and the personnel with the life jacket (ring) diving and falling water cannot be considered, so that a large number of people are lost, the water surface is not rescue, the falling water personnel are pulled and spread by ocean current, and the external rescue force is bothered. Such passive rescue concepts and operational rules are in urgent need of improvement.
