Summary
During preparations for subsea spool deployment, a spreader bar rotated and fell onto the deck and spool as rigging was raised after sea-fastening removal. A nearby rigger moved clear; nobody was injured. The flash identifies shortcomings in hazard communication, lifting sequence, change management and design risk review, and recommends task briefings and debriefs.

Summary
A vessel was set up alongside a barge in preparation for the subsea deployment of a 16″ (40cm) spool. The spreader bar sea-fastenings were removed by the deck crew and as the crane raised the rigging, the spreader bar rotated uncontrollably causing it to fall from its supports, with the forward end landing on deck and aft end landing on the spool
