Summary
During vessel transit between piling locations, unintended crane control activation lowered a suspended hammer, tightening its hydraulic umbilical until the coupling parted and the restraint chain snapped. The release totalled 960 litres of hydraulic oil. Identified measures addressed crane inactivity, communications, hose isolation, ROV observation and potential pollution-reduction arrangements.
