A member shares two incidents of hand injuries during mooring operations; one was very serious and resulted in the loss of a finger.
What happened – hand injury
Following the replacement of a damaged mooring line on an FPSO, two crew members installed protection to secure the new line. The task occurred during rough weather. As the mooring line slackened, one of the workers grabbed it to position the protective material. As they did so, the swell caused the vessel to move. The mooring line tightened, trapping and injuring the hand of the worker, who was not wearing suitable gloves at that point.
What happened - finger crushed
A deck foreman and riggers were at the aft mooring station port side, adjusting the floating aft Yokohama fenders to start mooring. The Deck foreman took over one of the rigger’s positions and while securing the mooring rope to the guardrail got his finger trapped between the handrail and the rope by a sudden movement of the rope. His middle finger was crushed and had to be amputated.
What went wrong?
- Hand rails were being used to secure the Yokohama fender because there was no dedicated mooring point.
- Manual adjustment of the arrangement for the Yokohama fender was not covered in the job safety analysis/risk assessment.
- The Deck foreman directly intervened in the operation rather than supervising.
- The Deck foreman was not wearing appropriate Impact Gloves at the time.
- Opportunities to stop the job were not taken.
Lessons to learn
- Dedicated and proper designed mooring points should be available and used to secure fenders.
- Supervisors need to supervise and resist the temptation to involve themselves in the actual task.
- Be ready to STOP THE JOB – stay proactive and alert during mooring operations.
- Be aware of risks to your hands and fingers when mooring – it takes only a split second for something to go wrong.
- Take great care if the weather is causing the vessel to move: if possible, consider doing the task later;
