Study Notes
Brass Screws Incident
- Specified maximum torque for brass screws is 4N; minimal force causes overtightening.
- Investigation revealed 22 screws failed due to inadequate strength against wave force.
- Screws were poorly manufactured and had been overtightened during installation.
- Actions taken include checking other screws, overhauling scuttles, discussions with metallurgists, and amending cabin procedures.
Dropped Cargo Incident
- Cargo weighing over 400kg fell approximately 5m onto the vessel deck, nearly injuring crew.
- Two wooden crates were improperly secured to a pallet, allowing movement and instability.
- A gust of wind contributed to the fall as the crane turned during lifting operations.
- Recommendations include using only certified crew for lifting, visual inspections of cargo, and avoiding lifting wooden pallets.
Fast Rescue Boat (FRC) Launch Incident
- During FRC testing in dry dock, an improperly removed lashing line caused a collision with a railing.
- Hydraulic piping leaked, necessitating an immediate halt to the operation; no injuries occurred.
- Issues included a lack of pre-launch checks, clear procedures, and communication.
- Proposed actions focus on comprehensive risk assessments and training for crew members.
Wedge Failure Injury Incident
- A crew member injured after a wedge shattered while attempting to open a cargo hold hatch using a sledgehammer.
- The wedge remained lodged and broke instead of coming out, causing debris to injure the crew member.
- Emphasizes the need for thorough checks and consideration of safe practices before using heavy tools.
- Lessons include evaluating the swing direction and force required to prevent accidents.
