3 S Fuel pumps Diesel engines consume Heavy Fuel Oil (HFO), Marine Diesel oil (MDO) or Intermediate Fuel Oil (IFO).

4 Modern Diesel engines are run on IFO, a fuel whose grade lies between that of HFO and MDO. HFO is a residual oil that is made suitable for driving Diesel engines by adding certain flammable substances. MDO is a high-grade fuel of low viscosity that is used when the vessel is manoeuvring.

5 Engine Fuel pumps HFO MDO From the Heavy Fuel Oil bunkertank the preheated fuel is led to the settling tank. Settling tank

6 In the settling tank water and impurities are separated from the fuel and drained off. s Drain-valve Engine Fuel pumps HFO MDO Settling tank

7 Engine Fuel pumps HFO MDO From the settling tank the fuel is led through a heater to preheat the fuel.

8 From the heater the fuel is led through a separator (purifier / clarifier) to purify the fuel. Engine Fuel pumps HFO MDO

9 sound Engine Fuel pumps HFO MDO From the separator the fuel enters the daily service tank for HFO.

10 There are two daily service tanks, so that one tank may be used while the other is being filled. sound Engine Fuel pumps HFO MDO Daily service tank

11 s Engine Fuel pumps HFO MDO From the daily service tank the fuel is pumped to a heater by the low pressure fuel pump (or booster pump).

12 Engine Fuel pumps HFO MDO From the heater the HFO is passed through a viscosity regulator.

13 Engine Fuel pumps HFO MDO From the viscosity regulator the fuel is passed through a fuel strainer, which filters the fuel.

14 sound Engine Fuel pumps HFO MDO From the fuel strainer the oil is led to the fuel pumps in the engine.

15 Diesel oil is used for manoeuvring and is stored in the MDO bunkertank. Engine Fuel pumps HFO MDO

16 After the DO has been pumped up from the bunkertank, the fuel passes through a purifier. Engine Fuel pumps HFO MDO

17 s Engine Fuel pumps HFO MDO From the purifier the DO enters the DO storage tank.

18 s Engine Fuel pumps HFO MDO From the DO service tank the fuel is led to the high-pressure fuel pumps in the engine.

19 A mixing tank is used for a gradual transition from HFO to DO. sound M ixing tank Engine Fuel pumps HFO MDO

20 sound Buffer tank (Circulating tank) The mixing tank, or buffer tank, can hold a quantity of fuel which will be circulated and led to the engine. Engine Fuel pumps HFO MDO

21 s Engine Fuel pumps HFO MDO The hot fuel fumes can escape through the air vent in the mixing tank. Air vent

23 Modern Diesel engines are run on IFO, a fuel whose grade lies between that of HFO and MDO. HFO is a residual oil that is made suitable for driving Diesel engines by removing certain flammable substances. MDO is a low-grade fuel of high viscosity that is used when the vessel is manoeuvring. …..because: 1

24 From the Heavy Fuel Oil bunkertank the fuel is led to the settling tank. 2 Engine Fuel pumps HFO MDO Settling tank

25 In the settling tank the fuel is drained off after it has been separated from water and impurities. 3 …..because: Engine Fuel pumps HFO MDO Settling tank

26 From the settling tank the fuel is first led through a purifier and then through a separator. 4 …..because: Engine Fuel pumps HFO MDO Settling tank

27 From the separator the fuel enters the daily service tank. 5 Engine Fuel pumps HFO MDO Settling tank

28 There are two daily service tanks: one to preheat the fuel, the other to purify the fuel. 6 …..because: Engine Fuel pumps HFO MDO Settling tank

29 From the daily service tank the fuel is pumped to a heater by the booster pump. 7 Engine Fuel pumps HFO MDO Settling tank

30 From the heater the HFO is passed through a separator. 8 …..because: Engine Fuel pumps HFO MDO Settling tank

31 A fuel strainer preheats and filters the fuel. 9 …..because: Engine Fuel pumps HFO MDO Settling tank

32 From the fuel strainer the oil is led to the low pressure fuel pumps in the engine. 10 …..because: Engine Fuel pumps HFO MDO Settling tank

33 Diesel oil is used for manoeuvring and is stored in three daily service tanks. 11 …..because: Engine Fuel pumps HFO MDO Settling tank

34 After the DO has been pumped up from the bunkertank, it is passed through a purifier. 12 Engine Fuel pumps HFO MDO Settling tank

35 From the purifier the DO enters the settling tank. 13 …..because: Engine Fuel pumps HFO MDO Settling tank

36 14 From the DO service tank the fuel is led through a separator, heater, viscosity controller and strainer to the fuel pumps in the engine. …..because: Engine Fuel pumps HFO MDO Settling tank

37 A mixing tank is used to drain off water and impurities from the fuel. 15 …..because: Engine Fuel pumps HFO MDO Settling tank Mixing tank

38 The hot fuel fumes can escape through the air vent into the mixing tank. sound 16 …..because: Engine Fuel pumps HFO MDO Settling tank Mixing tank
