This will assist in calculating savings, based on a variety of real life scenarios, the company claimed.
The SEA-Mate BOB system enables the crew on board the vessel to blend an engine-specific cylinder lubricant with the optimal neutralisation and detergent properties.
In-use 2-stroke engine system oil is blended with a high BN cylinder oil. The resulting cylinder lubricant composition matches actual engine operating conditions and fuel sulphur levels, making it possible to reduce cylinder oil consumption and mitigate issues, such as cold corrosion and excessive cylinder wear.
Under normal operating conditions, regular consumption of a 2-stroke engine’s system oil does not take place. Its additives are depleted and viscosity increases over time. As BOB generates a consumption of the system oil being used, the crank case oil is replenished with fresh oil with fresh anti-wear and detergent additives, etc.
As the refreshment becomes a reoccurring event, system oil viscosity is returned to its original state, reducing friction in the engine and thereby providing proven fuel savings of up to 1.5%.
The calculator allows customers to evaluate the different potential savings from their particular engines and running conditions and a vessel-specific savings potential report is generated.
This report highlights potential cylinder oil, as well as energy and consumption savings related to continuous refreshment of the system oil. Calculations are made on actual system and cylinder oil consumption and cost for both main engine and auxiliaries.
It also includes an estimate for expected reduction of maintenance cost – reduced cost for change of cylinder piston rings and liners, reduced cost for purifier maintenance and more.
The resulting report is emailed to the company’s inbox for further evaluation and support when building a business case.
Sune Lilbaek, head of sales at Maersk Fluid Technology, explained: “By using the value calculator, it is easy to see the potential cost savings achievable with the introduction of a BOB system. With over 200 installations to date, we have proven it is possible to achieve lubrication at, or close to, the lowest allowed consumption of lubricant as specified by the engine manufacturer.
“This results in proven reductions of up to 40% in 2-stroke engine cylinder oil consumption, as well as significant fuel and maintenance savings,” he claimed.
