   DIESEL OIL SYSTEM General Process system description: Ships marine diesel engines run on Heavy Fuel Oil (HFO), nowadays a low sulphur content, or Marine Diesel Oil (MDO) or Marine Fuel Oil (MFO). The diesel oil system has as its purpose, Receiving          Storage        Purification and distribution of diesel oil to the various users on the FPSO. The main function of the diesel oil system is to provide purified diesel oil to Topsides Main  Turbo Generators (Package A/B/C) Port and Starboard (Package D/E/F),  Fire water pump Day Tank  (5-TA-  1710A/B/C/D),  Inert  Gas  generators  Day  Tank  5  TA  1210  A/  B  and  Hull  users Essential diesel generator DO day Tanks 4TA 6520A/B/C,  Emergency diesel generator DO day tank 4TA 6710, Life Boat  refuelling, Crew Boat refuelling and Fast Rescue Craft refuelling.

BILGE SYSTEM 1.1.1      BILGE SYSTEM The Bilge is the lowest compartment on a ship, below the water line, where the two sides meet at the keel. Introduction: The bilge system enables water and oily water to be removed from machinery spaces, pump rooms, void spaces and other compartments.  There are two suction lines for emptying each bilge well. The first line is connected to the bilge through bilge main pumps (or daily bilge pumps) which have 5-10 m3/hr capacity. The second line is the direct bilge suction (or emergency bilge suction) and must be connected directly t emergency bilge pumps suction. This is used in emergency and at least two direct bilge suctions (or emergency bilge suction) must be provided at machinery space in each pontoon area in semi-submerisbile project and pump room and aft & forward machinery spaces in FPSO project. It is a classification requirement that the bilge system has an emergency connection that is connected to the largest seawater pump. This is pro
