Summary
A cargo barge’s centre bow bollard toppled while an additional mooring line was taken up during pipelay operations. Corroded securing bolts no longer connected it to the deck, and the bollard was not intended for mooring. The flash recommends engineered mooring arrangements and detailed inspection of bolted load-bearing connections.
