1 Where locking pins are provided as an FPD, the
pins should be designed so that they have a minimum factor of safety
of 6 as per the LSA Code, paragraph 6.1.1.6.
Where existing on-load release hooks are drilled to provide a locking
pin insertion point, the strength of the hooks should continue to
satisfy the relevant requirements in the LSA Code and
in the Revised recommendation on testing of life-saving appliances (resolution MSC.81(70), part 2, paragraph
5.3.1) and should comply with the requirements of the Guidelines
for the fitting and use of fall preventer devices (FPDs) (MSC.1/Circ.1327, paragraph 2.1). The modification
of the hook in this respect should be acceptable to the manufacturer
of the hook.
2 Where strops or slings with fittings (e.g. shackles)
are used as an FPD, the following test requirements should be considered:
-
.1 environment tests as set out in resolution MSC.81(70), part 1, paragraph
1.2.1 or equivalent;
-
.2 tests for rot-proof, colour-fast and resistant
to deterioration from exposure to sunlight and that they are not unduly
affected by seawater, oil or fungal attack as set out in resolution MSC.81(70), part 1, paragraph
2.4, or equivalent;
-
.3 prototype test to a factor of safety of 6;
and
-
.4 a factory acceptance test of 2.2 x SWL.
-
Note:
The factor of
safety should be based upon the SWL, which should be not less than
the total weight of the lifeboat when loaded with its full complement
of persons and equipment.
3 It is the responsibility of the lifeboat and
davit manufacturer to confirm that the attachment eye is suitable
for the use of the proposed FPD. If the lifeboat and/or davit manufacturer
is no longer available, the suitability should be determined by an
independent service provider.
