The salvage buoy is a container that produces water buoyancy. It is sealed around and can generate huge buoyancy when immersed in water. It can provide controllable buoyancy for sunken seas and salvage of sunken objects. It is one of the important equipments for emergency rescue in case of incidents. It is used to salvage sunken ships and sunken objects. It can also be used to assist stranded and rocked ships to get out of the water, and maintain the buoyancy and stability of damaged ships.

At present, there are generally two types of salvage buoys: metal buoys and rubber buoys. The buoyancy of metal buoys is large, there are several types of 500 tons, 400 tons, 200 tons, 80 tons, and 40 tons; the buoyancy of rubber buoys is small, such as 10 tons, 5 tons, etc. Metal buoys, with barrel, handguard, ladder, mooring hole, quick-sinking valve, inflation valve, submarine door, etc. on the outside; air box, safety pipe, partition board, inflation system, etc. on the inside; towing rings and lifting rings on the top , cable system or bollard, etc. Normally, the metal buoys are installed on the special slideway of the wharf, or drift on the water surface. Once necessary, they will be towed by the tugboat to the salvage operation site. According to the salvage implementation plan, the buoys will be sunk on both sides of the sunken ship, and the bottom jack will pass through the buoy fairlead. Set on the bollard of the buoy, fill the buoy with compressed air, the buoy will generate buoyancy and close to the two sides of the sunken ship, so that the sunken ship will float or fall off. In addition to being hung on a fixed position on a sunken ship or connected to the jack on the bottom of the ship, the rubber buoy can also be placed in the cabin of the sunken ship, and the water in the cabin can be removed after inflation to provide buoyancy.
