- Auxiliaries Systems: The auxiliaries Systems can be described and summarized as per the following:
| Auxiliaries System | Description | ||
| 1. | Fuel Handling System | Components: HFO day tank 300 m3; HFO buffer tank 80 m3; LFO storage tank 2500 m3; LFO day Tank 300 m3 ; HFO unloading pumps; HFO transfer pumps; HFO separation: 3x SA 871; ALFA LAFAL HFO separator unit; HFO feeder pumps; HFO auto & manual filters; LFO unloading pumps LFO transfer pumps | |
| 2. | Lube Oil Handling System | Components: New lube oil unloading pump; New lube oil tank 35 m3; New Lube oil transfer pump; Lube oil service tank 13 m3; Lube oil service tank transfer pump; Used lube oil tank 35 m3; Lube oil mobile transfer pump; Lube oil separators SA 871 Separation System Alfa Lava | |
| 3. | Oily Water & Sludge Handling System | The oily water system collects oil-contaminated water and separates it into clean water and sludge.
The collecting pits are emptied to the oily water buffer tank by transfer pump units. The transfer pumps operate according to signals from level switches in the collecting pits. The system also receives sludge from units equipped with separate sludge pumps. Components: Oily water feed pump unit; Oily water transfer pump unit; Oily water treatment unit, Sludge loading pump unit. |

| 4. | Water Treatment System | Components: Raw water tank; Raw water pumps, Multimedia Sand filter 6 m3/h; Active carbon filter 6 m3/h; Softener with auto flowing control, 2 parallel resin tanks; High pressure pump; Reverse Osmosis device with membranes; Pure water tank 3 m3, Pure water pumps; Daily concentrate water tank; Daily concentrate water pumps; Deaerator 5 m3; Feed water pumps. | |
| 5. | Steam System | Components: Waste gas heat recovery; Boiler 3 x 150 kg/h, 8 bar, 175 C ° EGS1.5-0.8NS; LFO Auxiliary boiler 150 Kg/h; HFO auxiliary boiler 200 Kg/h
Condensate tank 3 m3; Condensate water pumps. |
|
| 6. | Compressed Air System | The compressed air system includes two subsystems with separate compressor units.
a. The high-pressure air 30 bar needed for starting the engine is provided by the starting air unit b. The instrument air units supply air at lower pressure 7 bar to pneumatically operated devices on the engine and in the auxiliary systems. The starting air unit also has an outlet line with a pressure reducer, connected to the instrument air units. This enables the starting air unit to be used as a backup for the instrument air compressors. components: Starting air compressors; Starting air vessels, Instrument air compressors; Instrument air bottles. |
|
| 7. | Control System | The generating set can be controlled in automatic and manual mode; The main functions of the control systems can be listed as the following:
§ Start and stop of the generating set. § Synchronization § Engine speed and load control § Generator output control § Control of auxiliary systems § Monitoring and alarm handling § Safety functions, such as start blocking, shutdown and load reduction. Components: § Local control panels § PLC: The PLC system controls the operation of the generating sets and some of the auxiliaries. It collects data, executes controls, generates alarms and performs measurement scaling for the WOIS terminal. § WOIS (Wartsila Operator’s Interface System) workstation § WISE (Wartsila Information System Environment) workstation |
