All life rafts provided on board the ship must be equipped with a painter line permanently secured to the ship.
Each life raft or group of life rafts must be equipped with hydrostatic release unit, ensuring that each life raft can float freely. If it is an inflatable raft, it should automatically inflate when the ship sinks.
The storage of life rafts should allow for the manual release of one life raft or container at a time from the securing arrangements.
Life rafts launched by a davit should be stowed within reach of the davit hook unless some transfer device is provided to ensure that they can be operated within the required limits of inclination or during ship motion or power failure.
Life rafts used for throw overboard launching should be stowed on both sides of the ship to facilitate easy transfer for launching.
The characteristics of an inflatable liferaft are as follows:
The inflatable life raft is a life-saving equipment used by people in distress in the event of a shipwreck. When it is used, it is landed from the ship overboard. At this time, the life raft relies on its own CO2+N2 gas mixture to inflate form, and float on the water surface.
Life rafts have been widely used in all kinds of sailing ships, in Marine lifesaving equipment, playing an increasingly important role, becoming a major lifesaving equipment, but also the safest and most effective lifesaving equipment. Compared with other life-saving equipment, the most significant characteristics of inflatable life rafts are small size, lightweight, easy to use, stable performance, safe, and reliable.
The inflatable life raft is a new type of life-saving equipment developed in the 1960s, it is made of rubber, usually folded and placed in a glass steel container, the shape of the container is usually a hemispherical cylinder at both ends. When in use, pull the cable of the inflation valve, and the CO2 cylinder placed in the raft will automatically inflate the life raft, making it bulge into a round soft raft with a tent. The raft is also equipped with emergency drinking water, survival food rations, a first aid kit, lifesaving hand flares or rockets, and automatic distress radio and other items and equipment. There are also flashing lights on the roof of the tent, so that rescuers can search at night. People who ride in the tent avoid the impact of waves, cold wind or sun exposure.
