Pre-bunkering Checking Check List Oil spill response material in place e. Red fag ()by day /red light at night →。 Sandpiper pump prepared with hoses connected Deck to be drained for any water Scupper plugs to be replaced immediately (stand by when draining of water). All scuppers on deck must be tightly plugged
Pre-bunkering Checking Check List • Oil spill response material in place • Red flag (B) by day /red light at night. • Sandpiper pump prepared with hoses connected • Deck to be drained for any water. Scupper plugs to be replaced immediately (stand by when draining of water). • All scuppers on deck must be tightly plugged
e Pre-bunkering Checking check List Drip trays under the bunker manifold and ventilation pipes from bunker tanks to be drained for any water and the plugs to be replaced immediately(Stand by when draining of water) Anti-pollution prepared and ready for use. Oil absorbing material(sand, sawdust, etc. )to be ready at the manifold and around oil pollution drain. NO SMOKING? Sign to be displayed

Pre-bunkering checking check list Check that all bunker tank air pipes are open and unblocked Ensure that all sounding pipe caps are tight, except when sounding tank. Reconfirm space remaining in all bunker tanks to be filled Fire extinguishers(powder and fire loses)to be prepared ready at the manifold
Pre-bunkering checking check list • Check that all bunker tank air pipes are open and unblocked. • Ensure that all sounding pipe caps are tight, except when sounding tank. • Reconfirm space remaining in all bunker tanks to be filled. • Fire extinguishers (powder and fire hoses) to be prepared ready at the manifold
Pre-bunkering checking check list \. Ensure that bunker hose is correctly and safely connected →· Ensure that all unused bunker manifolds on booth sides of the vessel are secured and blanked tightly with bolts in every flange hole. The required bunker specifications must be obtained Both the officer in charge and the assisting crew must be familiar with the piping and valve line up

Pre-bun kering checking check list The procedures for Emergency Shutdown, Topping Tanks and Draining of lines and hoses to be agreed upon Inspect hose and couplings for damages. Discuss bunkering plan with supplier Discuss vessel's emergency response procedures with supplier
Pre-bunkering checking check list • The procedures for Emergency Shutdown, Topping Tanks and Draining of lines and hoses to be agreed upon. • Inspect hose and couplings for damages. • Discuss bunkering plan with supplier • Discuss vessel’s emergency response procedures with supplier
Pre-bunkering checking check list Discuss suppliers own emergency response procedure. Establish signaling system with supplier. Commence pumping -Reduce pumping rate- Cease pumping -Emergency stop Agree maximum pumping rate and pressure. Sampling prepared. Prepare filling line and open all relevant Ines

Bunkering instructions Mixing of fuels should be avoided due to possible incompatibility problems. Bunker tank utilization must be managed in such a way that mixing of fuels from different sources is reduced to a minimum. It is also important to consider the possible problems with slack tanks. Mixing stable fuel oils with equal performance may result in unstable fuel oil with a total dififerent performance
