Pragmatic Approach to Dealing with a Sea Water Leakage Flooding the Engine Room:

Immediate Actions

• Alert the crew and bridge: Immediately notify the bridge and slow down the main engine. Raise the emergency alarm to alert all personnel.
• Inform authorities: The Master must inform the Designated Person at the head office and other vessels.
• Secure the vessel: Initiate the Emergency Response Plan. Shut all watertight doors to contain the flooding and prevent it from spreading.

Damage Control

• Remove the water:
  • Start the bilge pumps to begin de-watering the engine room.
  • Rig up and activate portable pumps to supplement the main system.
• Monitor water levels: Continuously check if the water level is decreasing. If it is not, open the emergency bilge injection valve to increase pumping capacity.
• Locate and isolate: Find the source of the leak and, if possible, isolate it to stop or minimize the ingress of water.

Assessing and Mitigating Risk

• Evaluate the situation: Assess the danger to the crew, the vessel, and the potential for pollution.
• Address stability concerns: If the ship's stability is threatened, the Master should consider filling ballast water tanks to their maximum capacity. This can help to avoid the free surface effect, which can reduce the metacentric height and negatively impact stability.
• Prepare for power loss: In a severe scenario, the main engine and alternators may become powerless. Be prepared to switch to the emergency generator to maintain essential power and carry out repairs under these difficult conditions.
