The Marine Safety Forum (MSF) have published Safety Alert 18-19, in which a hoisted 10ft container became snagged on the bridle of a backloaded tote tank.
A ‘stop stop stop’ order was given and the crane operator immediately halted operation; the containers remained suspended 3m off the deck.
The crane operator attempted to free both containers, but the space on deck was too restricted, and he was forced to land the containers on top of a nearby tubular stack.
What were the causes?
An investigation revealed that:
- There was limited space to manoeuvre the containers due to lack of deck space.
- Whilst on location, the number of lifts declared for offload and backload changed significantly.
- The snagged bridle could not be seen from deck level or from above by the bridge team or the crane operator.
- The corners of the 10ft container were fitted with guiding pins, which prevented the snagged bridle from slipping free.
- The snagged bridle was not ‘tucked away’ or secured when the tank was backloaded.
What actions were taken?
- The deck crew removed the bridle once it was safe to do so.
- The containers were safely discharged, and the deck items were securely re-stowed.
- The charterer was informed in accordance with company procedures and this helped contribute to an effective and conclusive investigation taking place.
What recommendations were given?
- A toolbox talk (TBT) took place prior to the start of the operation – this TBT included the subject of checking for potential snag hazards. The vessel owner highlighted the need for all vessels to continue this practice and to continue searching for potential snag hazards both prior to and during operations.
- The deck crew were safe and clear of any risk during the operation. Crew members should remain in a safe place whilst lifting operations are taking place.
- The bridle of the tote tank could have been tucked away after disconnecting the hook – these actions would not have prevented the incident from taking place, but may help prevent future similar incidents.
- The bridge team should take time to research reporting requirements when going on hire and before a potential incident could occur.
