With the new S50ME&B, which will be designated Mk 9, we have introduced a competitive engine designed for new modern hull designs, based on more efficient propellers with a lower optimum propeller speed.

The engine will adopt the design features introduced on the smaller ME&B engines, and will be introduced with a mep of 21 bar at 117 rpm. However, as the ME&B technology has clear cost benefits for engines in the lower power bracket, we have decided to make this available also for the existing S50 Mk 7/8 range. This will make it possible to benefit from this technology also in existing ship designs if application of the advanced S50ME&C type is not considered feasible.
