Generally speaking, this type of vessel has a special storage place on a large vessel. When an accident occurs, we can throw it directly into the water. This life-saving vessel can automatically inflate itself and become the appearance of a vessel. At this time, the distressed person can sit in and escape from danger. If the large vessel you are riding in is in an accident, the vessel will soon sink. When you have no time to throw the lifeboat into the water, when the large vessel sinks to a certain depth, the storage device on the lifeboat is It will be automatically decoupled so that the rescue boat will be released for the distressed person to ride and help the distressed person to escape.

Lifeboats are important emergency life-saving equipment on board and are the focus of port state supervision inspections and domestic safety inspections. The scope of inspections of lifeboats involves their equipment, storage, landing and recovery devices, and the entire process of lifesaving exercises. The 1983 amendment to the International Convention for the Safety of Life at Sea (1974) of the SOLAS Convention stated that "Each crew member participates in at least one abandon ship drill and one fire drill every month. Each lifeboat shall be operated every 3 months At least one abandonment drill was conducted by a designated operator on the ship and launched on the water ", and the ship was required to place the lifeboat on the water within 30 minutes.
