Operational Intervention Quality, quantity, time loss, spillage, leakage, and overflow are important elements to consider during physical bunker replenishment operations. If we generalize all spillage, leakage and overflow as spills, these types of incidents are the primary source of petroleum pollution from ships.
Experience has shown that most bunker spills, leakage and overflow are caused by human error. All fuel replenishment operations should be carefully planned and completed in accordance with MARPOL regulations. In particular, the pollution caused by Fuel Oil is harmful and difficult to clean up.
The responsible personnel should not be distracted by any other work and should not leave their duties during topping-off. This is extremely important in order to prevent conflicts between fuel and cargo personnel during the simultaneous loading of bunker and cargo on the ship. Spills often occur as a result of personnel being distracted by other tasks.
Companies should demand that all fuel replenishment operations be carried out in accordance with the procedures of the ship’s Safety Management System and in a controlled manner. They should ensure that the risks associated with the operation have been reviewed and controls are in place to minimize them. In the event of a spill, essential and immediate measures should be known and implemented immediately.
