15.4 CERTIFICATION AND INSPECTION OF LIFTING TOOLS 15.4.1
All lifting tools shall be in good condition and thoroughly inspected before each lift or series of lifts.
Special attention should be given to the condition of the grippers and the hydraulic system (where
fitted) to ensure there is no corrosion or leaks.
15.4.2
Relevant test certificates shall be issued or endorsed by a body approved by an IACS member (see
Section 10.2.1 for IACS details).
15.4.3
The test certificate referenced in Section 15.4.2 shall be valid for a maximum of 4 years and the lifting
tool is to be inspected every 6 months by a Competent Person.
15.5 CERTIFICATION AND INSPECTION OF SPREADER BARS AND SPREADER FRAMES 15.5.1
All spreader bars / frames shall be in good condition and thoroughly inspected before each lift or series
of lifts. Special attention should be given to ensure there are no deformations, cracks or other defects,
there is no corrosion other than surface scale, the bearing surfaces at the rigging connection points are
in a good condition and that there are no indications of abnormal loading.
15.5.2
For a spreader bar / frame which is to be used for repetitive operations where there are more than 10
lifts, a load test certificate shall be supplied and shall specify the allowable static load, the applicable
DAF and applicable rigging arrangement (see Section 14.6.5).
15.5.3
For a spreader bar / frame which is to be used for repetitive operations (see Section 14.6.5 for load
test and certificate requirements), the spreader bar / frame shall be subjected to periodic NDT
inspection based on the utilisation of the spreader bar to the following requirements:
For a spreader bar / frame utilised at 90 to 100% of the WLL, NDT is to be carried out after
20 lifts or 50 hours of use, whichever is earliest;
For a spreader bar / frame utilised at 70 to 90% of the WLL, NDT is to be carried out after 40
lifts or 100 hours of use, whichever is earliest;
For a spreader bar / frame utilised at below 70% of the WLL, no periodic NDT is required.
The level of inspection shall be 100% of welds at the lift point area and 50% of welds on areas away
from the lift point. The NDT testing shall be visual for all welds, MPI for fillet, partial penetration and
butt welds with butt welds also tested with UT.
15.5.4
Where excessive or uncontrolled loading has occurred, the spreader bar / frame shall be subject to
NDT. This is to be carried out with all welds 100% visual, all welds 100% MPI with butt welds also
tested with 100% UT.
15.5.5
Where spreader bars or spreader frames are modified, the requirements of Section 14.6 are to be
carried out where applicable.
15.5.6
For spreader bars or spreader frames to be wet stored for an extended period prior to use (e.g. for the
recovery of a subsea asset), the means for satisfying any pre-lift inspection requirements should be
agreed. The fabrication requirements for wet stored spreader bars or spreader frames are referenced
in Section 14.6.8.
