Study Notes
IMCA Safety Flash Overview
- IMCA Safety Flashes provide summaries of key safety incidents to improve learning and prevent recurrence.
- Members are encouraged to share safety incidents for broader awareness and learning.
Incident: Loss of Heading Control During Diving Operations
- Occurred at a Floating Production Unit (FPU) during diving operations.
- Only one operational thruster (aft port) was available after isolation of the forward thruster and failure of the starboard aft thruster.
- Standby pump did not start, leading to total loss of azimuth control, resulting in loss of heading.
- Diving Supervisor secured the work site and ensured safe recovery of divers to the surface.
- Key issues:
- Maintenance of thruster equipment deemed routine and allowed during operations.
- Lack of risk assessment for heading control and emergency preparedness.
- Unclear communication regarding diver safety during the incident.
Incident: Tank Implosion Due to Lack of Knowledge
- A tank implosion resulted from a vacuum created during the pumping of Monoethylene Glycol (MEG) into a reservoir.
- The delivered tank was larger and unfamiliar to the operators, lacking necessary documentation.
- Manual air inlet valve, essential to prevent vacuum, was not opened due to inexperience.
- New supplier’s capabilities not properly evaluated prior to operations.
- Actions taken:
- Increased focus on supplier onboarding and familiarization with equipment.
- Ensure management of change (MoC) protocols are followed, especially involving third-party equipment.
USCG Alert on Discarded Munitions
- The United States Coast Guard issued Safety Alert 02-24 about hazards from discarded ammunition, containing explosives or chemical agents.
- Significant amounts of munitions remain in coastal waters, posing risks to fishermen and ocean floor workers.
- A recent incident involved a deckhand suffering severe burns from a dredged canister containing explosives.
Incident: Chain Hoist Failure
- An overhead electric chain hoist container weighing around 30kg fell approximately 0.8m, injuring a crew member during pipelaying operations.
- The failure occurred at one of the hoist's securing points.
- The container hit the crew member's shoulder/back, causing contusions and bruises.
