Shell Marine 40 extends life of high-speed diesel engines on tugboats

Tug operators can call on a new product for high-speed diesel engines with lubrication issues. Shell Marine has introduced an engine oil formulated for high-speed diesel engines.

Shell Marine 40 improves performance of the diesel engines as it reacts to the combustion processes inside them. Shell Marine global marketing manager Marcus Schaerer said this lubricant provides added protection and extends machinery life, helping to reduce wear on the engine from long-term operations.

“Poorer-quality oils can thicken or break down,” he explained. “Either way, the engine can become dirty and less efficient than its designers intended,” Mr Schaerer warned.

“The change is typically very gradual, almost imperceptible, so it is hard to detect on a day-to-day basis, but over time the degradation accumulates.”

Shell Marine 40 was produced to mitigate these problems. Its additive system controls piston deposits and helps to maintain good standards of engine cleanliness to ensure more efficient burning and higher reliability, said Mr Schaerer.

He went on to say that Shell Marine 40 helps to lower maintenance outlay and hence helps to improve vessel availability.

“High-speed engines that power tugs face a vastly different operational profile to a container ship or a dredger. We deliver lubricants that recognise and match the differing needs to help ensure that vessel engines can perform their jobs reliably and efficiently.”
