What happened?
During a routine rescue drill the self-righting frame assembly fell off the Fast Rescue Craft (FRC) into the water while the FRC was transiting at approximately 15 knots.

What went right?
- The hazards and risks of the rescue drill had been identified and discussed in the Toolbox talk with all personnel involved.
- Appropriate protocol was followed, and Bridge crew were kept in communication throughout the recovery operation.
- The FRC was repaired promptly to Original Equipment Manufacturer (OEM) specification.
What went wrong?
- A third-party inspection of the FRC had been completed two months before the incident. The inspection required only a visual check of the self-righting frame and did not include checking the integrity of the frame securing arrangements.
- Over time the securing arrangements were stressed and showed signs of galvanic corrosion.
What lessons were learnt?
- The integrity of self-righting frames should be periodically inspected. This may involve the removal of the frame.
- Reviewed FRC inspection checklist and procedure to ensure the self-righting frame is periodically removed and inspected.
