Cylinder lubricaton for every engine

Hans Jensen Lubricators is the leading provider of cylinder lubrication systems for 2-stroke marine engines. We’re the only supplier of cylinder lubricators to both MAN, J-Eng (MHI) and WinGD (Wärtsila/Sulzer) engines, in the World.

Our lubricators can be chosen for new buildings or as retrofit. In the case of retrofit, the installation of our products is flexible meaning we can upgrade the Main Engine outside of the docking period. In fact, the majority of the installation can be done while the vessel is sailing, and only a part of the installation needs to be done while vessel is in port.

At HJL, we know that your priority is your vessel schedule, so we fit OUR job into YOUR schedule – not the other way around.


Tripling liner life time

Hafnia, a member of BW Group, upgraded the engine’s cylinder lubrication system onboard their Medium Range Product Tanker, BW Egret, in January 2020. Liners previously had a wear rate that exceeded the maximum allowable limit.

Transparent partnership

We have experience working with Technical Managers and values long-term relationships built on mutual benefits and development. We offer our partners an extensive training program within product installation and maintenance as well as cylinder condition analysis.

Our digital lubrication platform HJ Smartlink™ takes cylinder lubrication online and presents live data on a number of parameters.

The data brings you full transparency of lubricator performance and allows for proactive actions for running as efficient as possible.

Backed by the leading, independent company within cylinder lubrication and condition analysis, you can develop your business even further into new value adding customer relations.

Mitigating risk

The pace of changes within the maritime sector has never been as high as now. The green transition presents a number of challenges, some of which, are more obvious than others.


Low load operation threatens cylinder condition

The most common method for EEXI compliance is Engine Power Limitation. This most likely means that the engine load is lowered by various means.

When the engine load is reduced, the original cylinder lubrication system reduces the injection frequency of the cylinder oil into the combustions chamber. In other words, the engine will run on “old” oil, during an increased number of “dry piston strokes” thereby deteriorating cylinder condition at reduced loads.

Here lies a serious risk of increased wear of the piston rings and liner. Read our article on how to mitigate this risk.


Requires flexible lubrication technology

All new fuel types have reduced lubricity due to the desulfurization process which removes the natural lubricating properties of the fuel. The lack of lubricity needs to be compensated for by maintaining a thin and stabile oil film in order to prevent bore polishing and scuffing.

Our technology injects fresh cylinder lube oil during each piston stroke and utilizes atomizing spray of lube oil for optimal cylinder lubrication regardless of fuel type and load.
