A recent Safety Flash by the International Marine Contractors Association (IMCA), focuses on an incident in which a member of the deck crew member put themselves in the line of fire during landing of a structure on the back deck of a vessel.
As IMCA informs, the installation aids (bumper bars) were insufficient to stabilise the load, resulting in the structure being landed narrowly missing the individual, and damaging an adjacent container. The bumper bars were a critical barrier for keeping the banksman safe on the walkway but as they were not spaced far enough apart for the structure, they allowed a rotational movement of the load.
What went right
- Before landing the structure, the area had been barriered off and non-essential personnel removed from the area;
- All the containers were checked to ensure no-one was working inside them during the lift.
What went wrong
- The individual was focused on landing the structure in a tight space and was relying on the bumper bars to keep him safe in the event of unplanned movement of the structure;
- Even though the design of the installation aids (bumper bars) was within the vessel’s design code, they were not there to protect people, but there as aids to landing and moving structures around the deck without damage. As they were not designed for personnel protection, the distance between them was not considered.
Lessons learned
- There was a general misconception that installation aids can be used as personnel protection devices, but this is not their design nor their appropriate use;
- Moving the counterweight location and bumper bars was seen as an improvement by the vessel team and therefore they did not go through a Management of Change (MOC) process. Even perceived improvements may have negative consequences and need to be managed;
- Despite all the good work done in pre-job planning, the banksman still put himself in the line of fire. In hindsight, this area should have been a complete no-go zone.
- Take into account when planning work, the difference between “work as imagined” and work as actually done;
- Remain aware of your close environment and understand that during lifting activities, the exclusion zone may change;
- Review tasks where installation aids are being relied on for personnel protection. Should a wider exclusion zone be put in place for these tasks?
