Snagged Cargo Carrying Unit During Offshore Discharge

Cause & Consequence

• Contact with something fixed or stationary

Incident Location

Support vessel eg Supply, Standby

Incident Activity

Lifting, crane, rigging, deck operations

Lessons Identified

The re-enactment exercise was very useful as it validated our perceptions. I.E.:-

1. Skips with corner stacking points are more likely to snag in the vessels safe haven

openings compared to skips with inboard stacking points.

2. Safe haven openings with a rounded top significantly reduce the likelihood of skips and

other CCU’s snagging.

Incident Recommendations

The Recommendations from this investigation are:

1. CCU manufacturers to consider re-engineering units which have corner stacking points

2. Safe haven openings to be constructed so as to incorporate a rounded edge (approximately

100mm diameter) around the upper third of the opening

3. When loading deck cargo consider the potential for CCU’s to snag on vessel structures, in

particular safe haven openings

4. OOW/Deck crew to provide guidance/instruction to crane operators on best position for

CCU’s on their vessel

5. Consider where practicable loading CCU’s with snagging potential away from the safe

haven openings

6. Make installation aware of any lifts that have the potential to snag
