Lube Oil Care Marine Diesel Engines (4-stroke) | Supply Vessel
Customer Case
Marine Diesel Engines
Ship: Supply ship
Engines: BERGEN, 2,500 kW/750 rpm (2 units), 4-stroke diesel engines
Lube Oil: SHELL GADINIA AL 40
Test: Centrifuge vs CJC® lube oil filter
Test period: > 10,000 operating hours
Test start: at 144,992 operating hours
Test end: at 155,123 operating hours
Conventional lubricating oil treatment: One centrifuge (lubricating oil separator) per engine. Volume flow: 550-810 l/hour.
Newly installed CJC® Lube Oil Filter: During the test period, a CJC® Lube Oil Filter 27/108 was installed on one of the two engines (ME 2) for continuous fine filtration and dewatering (24/7/365). The automatic temperature controlled flow ensures optimum operation and the highest filtration efficiency. Pump flow: 1,150 L per hour (0.3 L/kW) nominal
Savings benefits
Approx. 97.5% lower energyconsumption≅ 229,774 kW/year and centrifuge
- ME 1 with centrifuge, energy consumption ≅ 235,468 kW (26,88 kW for operation + preheater)
- ME 2 with CJC® Lube Oil Filter, energy consumption ≅ 5,694 kW (0.65 kW for operation)
Approx. 97.8% less CO2 emissions ≅ 159,649 kg/year and centrifuge saved
The combustion of 1 liter of diesel or thermal disposal of 1 liter of waste oil/oil sludge produces approx. 2.6 kg of CO2.
Lower energy consumption:
- ME 1 with centrifuge ≅ 143,246 kg CO2
- ME 2 with CJC® Lube Oil Filter ≅ 3,463 kg CO2*)
*) Based on consumption of approx. 187 g fuel per kWh.
Lower amount of sludge to be disposed of:
- ME 1 with centrifuge ≅ 19,929 kg CO2
- ME 2 with CJC® Lube Oil Filter ≅ 62.4 kg CO2
Approx. 99.7 % less oil sludge ≅ 7,641 liters/year and centrifuge
- ME 1 with centrifuge, discharge of sludge ≅ 7,650 Litres
- ME 2 with CJC® Lube Oil Filter, filter insert replacement ≅ 24 Litres
Approx. 60 % less lubricating oil consumption ≅ 8,940 liters/year and centrifuge
- ME 1 with centrifuge, discharge and diesel engine ≅ 14,900 Litres
- ME 2 with CJC® Lube Oil Filter, filter insert replacement and diesel engine ≅ 5.960 Litres
Approx. 60 % fewer person hours ≅ 8 hours/year and centrifuge
- ME 1 with centrifuge, Ø time for maintenance ≈ 20 hours
- ME 2 with CJC® Lube Oil Filter, Ø time for maintenance ≈ 12 hours
Approx. 86.25 % less operating costs ≅ EUR 30,199/year and centrifuge
