COSCO: 10 Vessels with Hans Jensen Lubrication System

One of the world’s biggest shipping companies, China COSCO Shipping Group, has placed an order for 10 large ore carriers from China State Shipbuilding Corporation. COSCO specified the order to include the cylinder lubrication system ‘HJ Lubtronic SIP’ from Hans Jensen Lubricators A/S, as it enables large cost savings through reduced cylinder oil consumption, and reduced wear on cylinder liners and piston rings. The first vessel is scheduled for delivery in January 2018.


Today’s energy efficient diesel engines for marine vessels are designed to reduce environmental footprints and fuel costs. However, the engines operate under different pressure and temperature conditions compared to older engines, and thus, corrode faster. This require new standards for cylinder lubrication to ensure lowest possible wear at the lowest possible oil consumption.


“Corrosion happens when the acid condensates on the liner surface. To reduce corrosion, it must be neutralized with cylinder oil. However, the standard lubrication system used by many engine makers, cannot deal with these challenges efficiently with their technology. Our technology, however, is designed to meet exactly these challenges and deal with them in the most effective way,” says Christian H. Jensen and continues: “COSCO chose our HJ Lubtronic SIP system because it enables shipowners to reduce cylinder oil consumption by 30-60 percent without increasing wear of the cylinder liners nor piston rings – quite the contrary, as the wear rate with a HJ Lubtronic SIP system is often reduced even with a lower consumption of oil. This also reduces costs of replacing the liners and other components, and minimize interruptions of the vessel operation.”


Future-proofs engines on newbuilds and retrofits

The HJ Lubtronic SIP system combines the SIP oil injection technology for two-stroke marine diesel engines, with the HJ Lubtronic pump unit, for all kinds of cargo vessels with two-stroke marine engines.
