1.6 Oil fuel transfer Oil fuel transfer arrangements provide for receiving stations at an upper deck level, port and starboard, furnished with valves, elbows, pressure gauges, filters and relief valves

1.6 Oil fuel transfer From these receiving stations. the oil flows to double-bottom, peak or BUNKERING ROUTINES Guidelines for bunkering of fuels deep bunker tanks and can be transferred from forward to aft and 7 fro om port to starboard (and vice versa) and from settling to service tanks via filters separators and clarifiers thence to boilers or engines

1.6 Oil fuel transfer • From these receiving stations, the oil flows to double-bottom, peak or deep bunker tanks and can be transferred from forward to aft and from port to starboard (and vice versa) and from settling to service tanks via filters, separators and clarifiers, thence to boilers or engines

1.6 Oil fuel transfer Fire is an ever-present hazard and often has its origin in apparently unremarkable happenings There are stringent rules governing flash points, permissible temperatures, storage and handling of oil fuel These rules should be carefully studied and observed

1.6 Oil fuel transfer • Fire is an ever-present hazard and often has its origin in apparently unremarkable happenings. • There are stringent rules governing flash points, permissible temperatures, storage and handling of oil fuel. • These rules should be carefully studied and observed

1.6 Oil fuel transfer The flash point(closed test)should be above 65C e do should not be heated to more than 51C for settling or purification; if necessary this may be increased to a figure 20"C beneath its known flash point Settling tanks must have thermometers and the sounding arrangements must be proof against accidental egress of oil

1.6 Oil fuel transfer • The flash point (closed test) should be above 65℃; DO should not be heated to more than 51℃ for settling or purification; if necessary, this may be increased to a figure 20℃ beneath its known flash point. • Settling tanks must have thermometers and the sounding arrangements must be proof against accidental egress of oil

1.6 Oil fuel transfer SELF CLOSING COCK Drain cocks must be self- DECK CONTROLLED closing and the outlet valves VALVE should be capable of being closed from safe positions SERVICE TANK outside the engine room In passenger ships, this rain applies also to suction and valve leveling valves on deep tanks

1.6 Oil fuel transfer • Drain cocks must be self￾closing and the outlet valves should be capable of being closed from safe positions outside the engine room. • In passenger ships, this applies also to suction and leveling valves on deep tanks.

1.6 Oil fuel transfer Overflow pipes and relief valves not in closed e circuit must discharge to an overflow tank having an alarm device, the discharge being visible Tank air pipes must have 25% more area than their filling pipes and should have their outlets situated clear of fire risks They should also be fitted with detachable wire gauze diaphragms Provision should be made for stopping oil fuel pumps from outside the machinery spaces

1.6 Oil fuel transfer • Overflow pipes and relief valves not in closed circuit must discharge to an overflow tank having an alarm device, the discharge being visible. • Tank air pipes must have 25% more area than their filling pipes and should have their outlets situated clear of fire risks. • They should also be fitted with detachable wire gauze diaphragms. • Provision should be made for stopping oil fuel pumps from outside the machinery spaces

1.6 Oil fuel transfer From the filling stations, pipes descend to the oil fuel mains These will probably be two pipes, one for heavy oil and one for diesel fuel They extend forward and aft in the engine and boiler rooms, possibly extending along the shaft tunnel, and in some ships, a forward pipe tunnel

1.6 Oil fuel transfer • From the filling stations, pipes descend to the oil fuel mains. • These will probably be two pipes, one for heavy oil and one for diesel fuel. • They extend forward and aft in the engine and boiler rooms, possibly extending along the shaft tunnel, and in some ships, a forward pipe tunnel

1.6 Oil fuel transfer These connect to the fuel transfer pumps and to distribution valve chests, from which pipes run to the fuel tanks Water ballast is also sometimes carried in these tanks and the chests are arranged so that they cannot be connected to oil and ballast mains at the same time(old tanker) Midship tanks have center and wing suctions; the forward and aft peak, and keep tanks have center suction only

1.6 Oil fuel transfer Transfer pumps draw from the oil mains, from overflow and drain tanks and from the oily bilges-parts of the engine and boiler room bilges separated from the remainder by coamings-to which oil spillage is led e. The pumps discharge to settling tanks the oily water separator and the oil mains
