A section of 36-inch gas export line they were working under or near fell off the approximately 60cm high temporary wooden supports (skid stacks) and crushed them. The two employees, a grinder and a welder, were completing a construction weld repair at the north-eastern-most weld joint of an approximately 120m curved section of the export pipeline.

The IOGP report notes the following:

  • The work permit system in place was rigorously applied to the known risks, but there was a lack of awareness of:
    • The hazard presented by temporarily suspended pipes, which constituted a dynamic load/dropped object hazard
    • The hazard of thermal expansion, differential heating, and residual pre-stress forces contributing to the lateral movement of curved pipe segments.
