Blending on-Board (BOB) technology allows owners to produce a Fit-for Purpose cylinder lubricant onboard, by blending the in-use system oil with a higher-BN cylinder oil product, which facilitates the addition of fresh system oil to the engine sump. Marine Fluid Technology and the BOB system is sold in Germany by Bindemann Group.
BOB gives the engineers onboard the possibility to adjust the BN of the cylinder oil to meet different Sulphur contents and detergency needs in the engine without raising the feed rate, the need for additives can be adjusted with the BN and not with the feed rate as has been the norm previously.
On vessels using compliant fuel this has shown to be a huge benefit. With a blender they can blend the cylinder oil to a BN number that gives enough detergency without causing over lubrication issues which makes it easier to optimize the feed rate.
No matter if the vessels are using scrubbers or compliant fuels the use of system oil from the engine and renewal of the oil in the engine keeps the system oil renewed and clean which reduces the build up of deposits in sensitive areas of the engine like the piston crowns and reduces the wear on sensitive hydraulic components in modern engines.
The blender is connected to the oil system onboard taking high BN cylinder oil from the storage tanks, used system oil from the main engine settling tank and then feeding the blended oil to the day tank. The installation can be done by the crew onboard while the vessel is sailing.
