0027-nd rev 11.2 8-jul-16 guidelines for marine lifting and lowering operations

14.6 
MATERIALS AND CONSTRUCTION OF SPREADER BARS AND SPREADER FRAMES 
14.6.1 
The material selection, fabrication method and NDT should be carried out in accordance with a 
recognised code. 
14.6.2 
All material shall be suitable for the intended service conditions and shall have adequate properties of 
strength, ductility, toughness and weldability.
14.6.3 
All material should be certified with traceability of material used in the fabrication of the spreader bar / 
frame. 
14.6.4 
The as-built fabrication package for the spreader bar / frame should be made available for inspection 
as required and contain, as a minimum, the following: 

Material Certificates,

Traceability of materials

Welding procedure specifications and qualification for the procedures,

Welding consumable certificates,

Traceability details for welds

NDT report, 

Heat treatment reports (if required)

Dimensional reports

Certificates for welding personnel

Certificates for NDT personnel

Weight report (if required)

As-built drawings

Release Note and any external certification.
14.6.5 
For a spreader bar / frame which is to be used on projects where there are more than 10 lifts or the 
spreader bar / frame is rented in from an external supplier, the spreader bar and rigging shall be load 
tested to, as a minimum, 1.25 x Dynamic Lift Load (where the Dynamic Lift Load is based on the 
maximum static load of the lifted structure, including rigging below the spreader bar, multiplied by the 
appropriate DAF – see Section 5.5). The allowable maximum static load (i.e. the static load used in 
the derivation of the Dynamic Lift Load for the load test) and the applicable DAF used on the load test 
and rigging configuration(s) applicable to the load test shall be clearly stated on the spreader bar / 
frame or the load test certificate. 
14.6.6 
For a spreader bar / frame which is to be used on projects where there are less than 10 lifts, the 
requirement for load testing is not required provided the spreader bar / frame is designed in 
11
