The low-pressure MAN B&W ME-GA engine delivers best-in-class CAPEX for LNG carriers
The low-pressure MAN B&W ME-GA two-stroke dual-fuel LNG engine delivers a low CAPEX solution that is the perfect choice for certain vessel types and applications, such as LNG carriers which are able to use "boil-off" gas as a source of fuel, or smaller ships where low capital outlay is a priority.
Based on the well-proven MAN B&W dual-fuel design with minimal installation requirements, the MAN B&W ME-GA uses an efficient ignition concept and a unique gas admission system that delivers safe and reliable operation at the lowest possible cost.
The engine benefits from a proven and cost efficient Exhaust Gas Recirculation (EGR) design for significantly lower NOx, CO2 and GHG emissions.
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, for example with minimal installation and operational costs, simple supply and purging concepts and low maintenance costs of the fuel-gas supply system, which in combination with the cost effective and proven EGR design, put the ME-GA engine in a very strong position compared to other two-stroke low-pressure LNG engines.Well-known engine room design accommodates simple installation, and the distinctive features from the well known ME-GI platform enables you to take advantage of crews existing ME-GI know how

ME-GA - The latest dual-fuel MAN B&W two-stroke engine
The ME-GA engine design concept is the premixed Otto principle, and the efficient performance of the engine is the result of an in-house developed exhaust gas recirculation (EGR) solution. The high-pressure EGR solution has been optimised for the ME-GA engine with performance-enhancing results, which include high performance efficiency, significantly reduced methane slip, and Tier III compliance when operating on conventional fuel oils. Moreover, the development of the ME-GA engine solution, which requires only a low-pressure fuel supply, has been performed with focus on reducing capex for the LNG carrier segment. This paper introduces the unique on-engine gas admission system, and discusses the new engine optimisation achieved with the proven EGR system. The first ME-GA engine available in our engine programme is a 70-bore engine aimed at the LNG carrier segment.
