Study Notes
Safety Flash Highlights
- IMCA Safety Flashes are designed to share critical safety information and incidents, promoting learning across the community.
- Emphasis on anonymizing data to ensure confidentiality while sharing crucial safety alerts.
Loss of Pressure to Diver's Air Supply
- A diver experienced a pressure drop in their high-pressure supply regulator; recovered safely.
- Inspections revealed dried lubricant causing friction affecting the regulator’s performance.
- Light breathing from the diver led to insufficient pressure for proper regulation.
- Diving supervisor managed the situation effectively, ensuring diver safety without activating the secondary supply.
Equipment Related Injury
- An incident occurred where equipment fell on a worker's leg during a movement task.
- Incident highlights the risk in storage areas, particularly while cleaning equipment rooms.
Emergency Musters and Drills
- Incident 1: A stuck emergency alarm button delayed activation during a drill, raising concerns about equipment reliability.
- Recommendation to regularly test emergency alarm systems to ensure functionality.
- Incident 2: A smoldering fire from improper disposal of a cigarette butt could escalate due to negligence.
- Importance of adhering to fire safety protocols in designated areas.
Bunker Hose Damage during Connection
- Damage to a bunker hose occurred during offshore operations due to stretching from vessel movements.
- Hose was tied off to the supply vessel while still connected to the crane, complicating the operational dynamics.
- Resulting actions included a review of risk assessments and bridge communication protocols regarding hose handling during bunkering.
- Highlighted the critical need for procedure adherence to prevent environmental spills and operational delays.
Overview of Incidents
- Loss of azimuth control affected thruster operations on a Floating Production Unit (FPU).
- Divers were safely recovered due to prompt communication and supervision by the Diving Supervisor.
- The turret rotation was locked, mitigating risks during the incident.
What Went Right
- The dive was aborted successfully.
- Divers returned to the surface safely through a controlled operation.
What Went Wrong
- Routine maintenance should not occur during diving operations with only one thruster in service.
- Lack of risk assessment in heading control and Emergency Preparedness Plan contributed to incident severity.
- Communication from FPU control regarding diver status was unclear.
- Greasing of the main steering pump was not typically allowed during diving operations.
- No Lock-out/Tag-out (LOTO) procedures for standby unit led to unexpected failures.
Incident Contribution Factors
- A 26 cubic metre tank, larger than planned, was unfamiliar to operators with no prior documentation.
- Tank design required manual air inlet valve operation to prevent vacuum—this step was omitted, leading to implosion.
- Inadequate supplier onboarding and familiarization regarding new equipment specifications.
- Insufficient insight into new suppliers' experiences during risk assessments.
Specific Equipment and Procedures
- MEG (Monoethylene glycol) is used to prevent hydrate formation in subsea pipelines.
- Third-party operators lacked knowledge of the carbon fibre tank specifications.
Subsequent Actions
- Emphasis on enhanced onboarding for new suppliers and better familiarization with equipment.
- Operators to be trained on equipment specs and risk assessment documentation.
- Management of Change (MoC) processes to be reinforced when changing equipment, particularly with third-party gear.
United States Coastguard Alert (USCG)
- Safety Alert 02-24 issued about hazards from discarded munitions, which include active explosives and chemical agents.
- Significant amounts of munitions remain buried post-1970 dumping practices posing risks to ocean floor workers.
Clamming Vessel Incident
- A deckhand was burned by an unexploded canister while dredging clams, highlighting risks with discarded munitions.
Chain Hoist Incident
- An electric chain hoist failed, causing a 30kg container to fall onto a crew member, resulting in bruising and contusion.
Tank Slip Incident
- A crew member slipped exiting a freshwater tank due to pooling water during cleaning operations, resulting in a closed fracture of the forearm.
- Safety controls and training were in place, but a slippery surface was the primary cause of the incident.
