Engine Room Fire

• Fire occurred in a vessel's engine room
• Fire was detected by a crew member
• Attempts to extinguish the fire with portable extinguishers were unsuccessful
• The fire escalated rapidly, impacting the starboard main engine and surrounding areas
• Temperatures exceeded 660°C, causing significant damage, destroying the engine room and adjacent spaces
• Response from fleet and local authorities was swift, preventing further escalation and ensuring crew and passenger safety

Near Miss: Smoke and Fire on Main Engine Exhaust

• Smoke and fire were observed during sea trials, originating from the turbocharger flange to the exhaust manifold of one engine
• The gasket on the turbocharger flange was damaged, the wrong gasket was installed
• The installed gasket was designed for a maximum temperature of 300°C, while the correct gasket should have been rated for 500°C
• Residual material from the combustion chamber may have contributed to the issue

Inappropriate Automatic Activation of Fixed Fire-Fighting System

• The fixed firefighting system in a harbor tug's engine room automatically activated, emptying all tanks
• Activation occurred after two consecutive blackouts within a 24-hour period
• The system was triggered by a sudden rise in battery voltage following a solenoid valve malfunction
• The tug's electrical system may not have sufficient power to supply critical equipment during emergencies
• Lack of indication on the bridge or in the engine room regarding the electrical system's operation, making it impossible to discern normal or emergency mode

NTSB: Fire on Vessel – Escaped Exhaust Gases

• A fire broke out in a stateroom on a towing vessel
• The fire was extinguished, the crew evacuated safely with no injuries and no reported pollution
• The fire originated behind panels in the pilot's stateroom, located between two engine exhaust stacks
• Cracks in the starboard muffler allowed hot exhaust gases from the running engine to escape into the stack area
• Combustible materials in the stateroom contributed to the fire's spread
• The NTSB suggests that undetected cracks in the muffler allowed hot exhaust gases to ignite wood structures
