0027-nd rev 11.2 8-jul-16 guidelines for marine lifting and lowering operations
GUIDELINES FOR MARINE LIFTING & LOWERING OPERATIONS 0027/ND Rev 11 Page 33 of 84 For wire ropes:
Hand splices on wire ropes:
1.25 (refer to EN 13411-2 for requirements)
Steel ferrules (mechanical termination):
1.12 (refer to EN 13411-3 for requirements)
Resin sockets:
1.00 (refer to EN 13411-4 for requirements)
Swage fittings, e.g. “Superloop or Flemish Eye”: 1.00 (refer to EN 13411-4 for requirements)
Aluminium or aluminium alloy ferrules:
2.0 (see note 1 below)
For cable laid slings and grommets:
Hand splices on cable laid slings
1.33 (refer to IMCA M 179 for requirements)
Cable laid grommets
1.00 (refer to IMCA M 179)
For fibre rope slings (all diameters):
Fibre rope sling splices (Dyneema, HMPE):
1.0 (see note 2 below)
Note 1: The use of alloy or aluminium ferrules is not normally recommended for any lift in a marine
environment due to corrosion and should only be used for light lifts with the slings stored in
very dry conditions and care must be taken that the right sized ferrules have been used.
Note 2: Fibre slings shall be tested with the actual termination and so a
s
= 1.0 can be used
Other methods of termination (i.e. 9-part slings) will require special consideration and the termination
efficiency documented.
7.7.2
It should be noted that termination and bending factors should not be applied simultaneously (see
Section 7.8). The one which results in the lower value of breaking load will govern, and should be
used.
7.8 BENDING FACTOR
