A ring-shaped floating life preserver. Lifebuoys are required, primarily to assist in „man-overboard” situations.

According to SOLAS the minimum number of lifebuoys on board ships depends on length of a ship in meters. Lifebuoys shall be stowed on both sides, on all open decks extending to the ship’s side, and not permanently secured in any way.

At least one lifebuoy on each side of the ship must be fitted with a buoyant lifeline.

Not less than on half of the total number of lifebuoys must be provided with self-igniting lights. Not less than two of these must also be provided with lifebuoy self-activating signals and be capable of quick release from the navigation bridge.
