Diesel spill during vessel re-fuelling

  • What happened?

    The officer of the watch (OOW) was proceeding to transfer fuel to the day-tank. While walking from the starboard fuel manifold to the port day-tank, he caught his foot on the hoses he had been using for cleaning and slipped.

    He went to the bridge to check up on himself and report the accident, but he forgot to stop the transfer pump before going up there. When he realised that he had left the pump running, he went back to the engine room and shut it off.

    Around 90 gallons (409 litres) in total of diesel got spilled, and approximately half of that total reached the sea.

  • Why did it happen?

    Pumping operations were left unattended.

    The scup plug was not installed before the transfer.

    Multiple unfinished work tasks led to the slipping hazard.

  • What did they learn?

    Make sure pumping operations are not left unattended.

    Workers should perform one task at a time to prevent potential hazards from carrying over to the next task.

    Verify integrity of secondary containment (in this case scup plug) before fuel transfer operations.

    Make calculation prior to refuelling to determine the time required to refuel the day-tank.
