A badly made Flemish eye crane pennant failed on an offshore installation dropping of a 9.5 tonne load causing what the UK’s Heath & Safety Executive calls “a serious incident. Inadequate testing by the manufacturer and incomplete technical information lead to the Flemish eye being manufactured with a mismatched ferrule/wire rope arrangement.
This incident occurred on an offshore installation during the lifting of a container weighing 9.5 tonnes. A 5 metre long, 15 tonne working load limit crane pennant was connected between the crane hook and the master link on the container sling set. The crane pennant had been manufactured from 36mm diameter wire rope and the eyes on each end had been formed by using the Flemish eye technique. Steel ferrules had been used as the termination and these had been pressed over the Flemish eye rope strand tails. During the lifting of the load the wire rope strands in the tails of the Flemish eye connected to the pennant hook became free inside the ferrule allowing the Flemish eye to unravel and the load to fall.
