Lubricating Dual-Fuel Auxiliary Engines: A Practical Approach

As an increasingly diverse marine fuels market adds complexity for ship operations, owners are looking for simplified solutions to optimise engine performance. Chevron Marine Lubricants’ recent work with dual-fuel four-stroke engines highlights a practical approach to these challenges.

Dual-fuel LNG engines are being installed on more and more vessels, driven by an expanding fleet of LNG carriers as well as the rise of LNG-powered propulsion in other vessel segments. Along with emissions benefits in gas mode, these engines provide fuel flexibility, with the ability to run on either LNG or fuel oil dependent on availability. That flexibility means that lubrication requirements for the same engine can change depending on how the fuel is used.
