First shipping sector deal for MAN 49/60 medium-speed engines

The MAN 49/60 engine successfully passed its type-approval test in March 2023 and features a power-per-cylinder of 1,300 kW, reducing the number of installed cylinders necessary to meet power demands. While in this particular project six-cylinder engines are applied, the L-type of the engine can accommodate up to 10 cylinders, which makes it capable of propelling ships typically powered by V-type engines. The 49/60 is also available as 12V and 14V engine variants.

According to MAN ES, "A key determinant in choosing the 49/60 engine was its ability to fulfil the load-acceptance requirements demanded by the TSHD’s diesel-electric propulsion system in diesel mode. The next-generation MAN common-rail system 2.2, in combination with the two-stage turbocharging system used by the engine, enables it to compromise between load acceptance and efficiency. Additionally, the next-generation SaCoS 5000 engine-automation system enables the engines to fulfil cyber-security requirements and offers enhanced remote-support possibilities."

MAN ES also announced continued sales of its ME-GA engines, with Japan’s Nippon Yusen Kaisha ordering four sets of engines for a series of four newbuild LNG carriers. All eight MAN engines have MAN ES’ exhaust gas recirculation bypass systems that aim to lower emissions. 

MAN Energy Solutions head of two-stroke business, Bjarne Foldager said, “We developed this engine for easy application to most contemporary LNG carrier designs and, indeed, all ME-GA orders to date have been exclusively for this segment. Demand for the engine has been continuously strong since its introduction, especially due to its accompaniment by our self-developed EGR system that comes proven by more than a decade of in-service, operational experience and optimisation.”
