3.3 FUEL OIL SYSTEM
The engine fuel oil system is designed for a reliable combustion of Heavy Fuel Oil
as well as Diesel Fuel Oil.
- FO filter             : Auto filter
- FO viscosity controller: With FO heater, control panel
- FO booster pump     : Screw type, electric motor driven
- FO mixing tank       : Cylindrical, with de-gas v/v
- FO supply pump     : Screw type, electric motor driven
- Fuel piping & lines    : Heat traced
- FO service tank      : With steam heating coil, level gauge
- Fuel oil treatment unit: The fuel oil treatment unit is designed for proper cleaning of heavy fuel oil considering total fuel consumption of D/G set.
 
3.4 LUBRICATING SYSTEM
The engine has its own internal lubricating oil system with wet type oil sump, which supplies lubricating oil to all moving parts for lubricating as well as cooling.
