Summary
During a production flexible’s second-end transfer, residual torsion caused the pipe and an attached 16.5te chain to rotate, nearly striking two crew members. The flash identifies task inexperience, language barriers and procedural omissions, and discusses rigging removal, translated task documentation and restricted access to the pipelay system’s top module.

Summary
During a transfer of the second end of a 4" (10 cm) production flexible, the production flexible began rotating due to residual torsion that had built up within the line. A 16.5te chain attached to the pull-in head also began spinning. Two nearby crew members who were observing the operation were almost struck by the spinning chain.
