Flashcards
What was the cause of the finger injury?
What was the cause of the finger injury?
During an emergency recovery of an ROV, an individual's finger was trapped between a crane wire and the ROV's recovery hook.
What were the circumstances of the incident?
What were the circumstances of the incident?
The incident occurred during an emergency recovery of the ROV. A small boat, an FRC, was used to facilitate connecting the ROV emergency rigging sling to the crane hook to allow recovery of the ROV to deck.
How did the finger injury occur?
How did the finger injury occur?
Before retrieving the crane hook, the worker had to release the ROV hook, attached to the crane wire with a thin rope, using a knife. As the worker did so, their finger was pinched, resulting in amputation.

Study Notes
Incident Details
- A worker suffered a finger injury while recovering a remotely operated vehicle (ROV)
- The injury occurred when the worker's finger was caught between a crane wire and the ROV recovery hook.
- The incident happened during an emergency ROV recovery operation using a small boat (FRC).
- Crane hook attached to an emergency sling on the ROV.
- The ROV hook was initially secured using a rope.
- The worker was tasked with attaching the emergency rigging back to the crane, and connecting to securing lines.
- The worker's task included releasing the ROV hook using a knife.
- The worker's finger was caught and amputated while detaching the hook.
Recovery Process
- A small boat (FRC) facilitated the connection of ROV emergency rigging to the crane hook.
- The crane's headache ball was submerged slightly.
- The crane was controlled by a forerunner with ropes.
- The plan was for a second person to use a boathook to retrieve the ROV hook.
- The crane operator retrieved the emergency rigging from the ROV and secured it to the FRC.
- The FRC moved away from the vessel.
Root Cause Analysis and Actions Taken
- Critical step of releasing the ROV hook from the crane wire was not identified.
- Insufficient planning and procedure detailing.
- Fault-finding procedures weren't implemented prior.
- Reviewed and updated Emergency recovery procedures.
- Enhanced planning, risk assessment, and task evaluation.
- Implemented regular training in emergency recovery scenarios using the FRC.
