MAN B&W ME-GA with superior EGR design

The MAN B&W ME-GA two-stroke dual-fuel LNG engine is the perfect fit for most contemporary LNG carrier designs. Based on the proven MAN B&W dual-fuel design, the ME-GA enables an easy integration into LNG carriers. Performance is optimized by the proven MAN exhaust gas recirculation (EGR) design. The engine uses an efficient ignition concept, while a unique gas admission system ensures safe and reliable operation. The engine benefits from a proven and cost efficient EGR design that reduces methane slip emissions compared to first-generation, first-generation Otto cycle engines without EGR. The low-pressure fuel gas supply system (FGSS) is easy to integrate and offers low maintenance costs.

Easy integration in LNG carrier designs

In addition to the advantages of using boil-off gas from LNG carriers, the MAN B&W ME-GA is exceptionally cost-efficient in other ways, such as its minimal installation and operational costs, simple supply and purging concepts, and the low maintenance costs of the fuel gas supply system. In combination with the cost-effective and proven EGR design, this puts the ME-GA engine in a very strong position compared to other two-stroke low-pressure LNG engines.

The well-known engine room design simplifies installation, and the distinctive features from the ME-GI platform are familiar to many crews.
