Oil Spill During Bunkering Operations
The vessel is bunkering heavy fuel oil at a terminal. The OIM is supervising. Suddenly, a hose connection on the ship's manifold fails, spraying oil onto the deck and into the water. Approximately 200 liters have spilled. The terminal's spill response team is not immediately available. The vessel's crew is trained in spill response. The weather is calm, and the spill is contained by the deck scuppers, which are plugged. However, some oil has reached the water. The port authority requires immediate notification. The OIM must act quickly.
1. What are the immediate actions to contain and clean up the spill, and what notifications are required?

Immediate actions:
- Stop bunkering immediately: Signal to terminal to stop pumping. Close manifold valves.
- Contain spill on deck: Use absorbent materials, sawdust, or spill kits to prevent further spread. Ensure scuppers are plugged.
- Prevent oil from reaching water: Deploy booms if available around the vessel.
- Clean up: Use absorbents to soak up oil on deck and water. Collect used absorbents in designated containers.
- Notifications: Inform terminal, port authority, and company as per SMS. Notify local coast guard if required.
- Activate shipboard oil pollution emergency plan (SOPEP).
- Record details: time, amount, actions taken.
Notifications: Port authority, terminal, company DPA, flag state, and coastal state if applicable.

Investigation:
- Inspect hose and connection: Check for wear, damage, or improper coupling.
- Review procedures: Was the connection properly made? Was pressure tested? Was a drip tray in place?
- Check crew training and supervision.
- Review bunkering checklist.
Prevention:
- Replace damaged hose.
- Ensure proper connection and tightening.
- Use drip trays and absorbents during bunkering.
- Conduct toolbox talk before bunkering.
- Implement stricter supervision.
- Update SMS if necessary.
