  • IMCA provides lessons learned from an incident in which during a routine rescue drill the self-righting frame assembly fell off the FRC into the water.
  • Lesson learned: Reviewed FRC inspection checklist and procedure to ensure the self-righting frame is periodically removed and inspected.

IMCA provides lessons learned from an incident in which 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, reports Safety4sea.

Furthermore, as the International Marine Contractors Association (IMCA) informs in its Safety Flash, the self-righting frame was recovered by the FRC crew and returned to the vessel, where the cause of failure was identified, and repairs completed. Furthermore, IMCA examined the incident finding:

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.

Lessons learned

  • 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.
