  10.13.1 At least eight lifebuoys of a type complying with the LSA Code should be provided on each unit. The number and placement of lifebuoys should be such that a lifebuoy is accessible from exposed locations. Surface units should carry not less than the number of lifebuoys prescribed in the following table:

Length of unit in metres Minimum number of lifebuoys
Under 100 8
100 and under 150 10

  10.13.2 Not less than one-half of the total number of lifebuoys should be provided with self-igniting lights of an approved electric battery type complying with the LSA Code. Not less than two of these should also be provided with self-activating smoke signals and be capable of quick release from the navigating bridge, main control station, or a location readily available to operating personnel. Lifebuoys with lights and those with lights and smoke signals should be equally distributed along the accessible portions of the perimeter of the unit and should not be the lifebuoys provided with lifelines in compliance with the provisions of paragraph 10.13.3. Lifebuoys fitted with self-igniting lights or self-activating smoke signals should be located outside hazardous areas.

  10.13.3 At least two lifebuoys in widely separated locations should each be fitted with a buoyant lifeline, the length of which should be at least one-and-a-half times the distance from the deck of stowage to the waterline at light draught or 30 m, whichever is greater. For self-elevating drilling units, consideration should be taken of the maximum height above the waterline, and for other drilling units the lightest operating condition. The lifeline should be so stowed that it can easily run out.

  10.13.4 Each lifebuoy should be marked in block capitals of the Roman alphabet with the name and port of registry of the unit on which it is carried.
