In this article,emphasis is made on the checklists, safety precautions, SOPEP locker and SOPEPequipment, temperature and density correction to calculate the quantity of oil bunkered.The formula for calculation has been included Bunkering Oil Earlier we learned about the bunkering and what is means. Now we will study the process of actual bunkering operations and the practical details of the process of bunkering oil. Alltypes of ships needs fuel oil, lube oil, etc. and hence it is important for everyone to understand the actual process of bunkering, so here we go. Pre-bunkering preparations. The most important aspect of bunkering operation are the checklists , which form a part of company's safety management system (SMS) and I.S.M.,eliminating the possibility andnegligence of human and other operational errors. The pre-bunkering checklist must befollowed in-consultation with the Chief Engineer (C/E), as he is the person-in-charge for the bunkering operation. Before bunkering, usually it is 4th engineering officer, taking soundings of bunker tanks and calculates the volume of fuel oil available in every fuel oiltank of the ship. Then a Bunker-plan is made to plan the distribution of total quantity of bunker fuel oil.Shell V-Power Nitro+ Shell.com.ph/v-powernitro+ Treat your car to the Premium driving Experience.

For example, on owning a car, we tend to keep a check on its fuel consumption widely calledas mileage. It is the distance travelled by the vehicle for a unit volume of fuel used. In thesame way, as the ship consumes humungous quantity of fuel, whose costs are forming themajor part of ship's operation. Managers tend to keep a check on it. This is measured interms of specific fuel oil consumption of the main propulsion engine.Upon knowing the fuel oil consumption for aday and the next voyage plan, the quantity of fuel oil required is calculated and comparedwith the available bunker tank capacity. A requisition is placed through the C/E and Master of the vessel to the Managers. The requisition is processed and evaluated for the qualityand quantity of fuel to be supplied for the particular ship. Planning is done for the deliveryof bunker at a particular port where the oil is available at a comparitive lesser cost. Ontaking all these aspects into consideration, the Managers, deliver bunker to the vessel.Upon receiving the bunker, a sample collected during bunkering operation is sent for labanalysis to confirm the delivered oil meets the required standard for the safe and efficientoperation of the auxiliary engines & main propulsion engine. Pre-Bunker Checklist 1. State of adjacent waters noticed2. Vessel properly secured to dock 3. Check suppliers product corresponds to ordered product4. Agree quantity to be supplied5. Check valves open6. Day tanks full and supply valves closed7. Warning signs in position e.g. No Smoking8. SOPEP plan available9. Clean up material in place10. Oil Boom in place11. Foam fire extinguisher placed at bunker station12. Alfa Laval and transfer pumps off 13. Fuel tank supply valves open14. Agree stop/start signals between vessel and barge/truck 15. Bravo flag flying/red light showing16. Agree pumping/transfer rate17. Agree emergency shut down procedure18. Specification sheet received19. Check hose and couplings are secure and in good order 20. Fuel nozzle and hose secured to vessel21. Check barge/truck meters Reading:22. Check on board meters Reading:23. Bunker Valve open24. Unused manifold connections blanked off 25. Master informed26. Signal pumping to commence The above checklist has to be completely filled religiously by both the ship & barge personnel.

During Bunkering Procedures - Checklist 1. Witness taking and sealing of 2 representative product samples2. Monitor fuel connections for leaks fuel flow and control tank levels3. Change over of tanks whenever necessary.
