Lifebuoy Requirements

Lifebuoy is a ring-shaped floating buoyant support which keeps a person afloat in water. Primarily to assist in „man-overboard” situations.

1. Appropriate numbers of lifebuoy available as per SOLAS by ship length.

 

2. Length of Buoyant Lifeline (at least 8mm dia) = Stowed height form                  lightest waterline X 2 or 30 m; whichever is greater

 

3. Total number of lifebuoy / 2 should be fitted with self-ignition light and

    among these half number at least 2 MOB on the bridge wing with a quick

    release system and in date.

 

4. Marked with name and port of registry of the ship.

 

5. Grabline (Dia- at least 9.5 mm) =  4 X outside diameter of Lifebuoy.

LIFEBUOY

 

1. Lifebuoys complying with the requirements of paragraph 2.1.1 of the LSA Code shall be:

 

.1. so distributed as to be readily available on both sides of the ship and as far as practicable on all open decks extending to the ship’s side; at least one shall be placed in the vicinity of the stern; and

 

.2. so stowed as to be capable of being rapidly cast loose, and not permanently secured in any way.

 

1.2. At least one lifebuoy on each side of the ship shall be fitted with a buoyant lifeline complying with the requirements of paragraph 2.1.4 of the LSA Code equal in length to not less than twice the height at which it is stowed above the waterline in the lightest seagoing condition, or 30 m, whichever is the greater.

 

1.3. Not less than one half of the total number of lifebuoys shall be provided with lifebuoy self-igniting lights complying with the requirements of paragraph 2.1.2 of the Code; not less than two of these shall also be provided with lifebuoy self-activating smoke signals complying with the requirements of paragraph 2.1.3 of the Code and be capable of quick release from the navigation bridge; lifebuoys with lights and those with lights and smoke signals shall be equally distributed on both sides of the ship and shall not be the lifebuoys provided with lifelines in compliance with the requirements of paragraph 1.2.

 

1.4. Each lifebuoy shall be marked in block capitals of the Roman alphabet with the name and port of registry of the ship on which it is carried.
