MAN Energy Solutions has announced that its MAN B&W ME-GA engine, the latest addition to its dual-fuel portfolio, has landed 40 orders since its market unveiling in March 2021. The company attributes the order surge to the market’s demand for the latest generation of Otto-cycle, two-stroke engines and the low levels of methane slip it can unlock. Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business, MAN Energy Solutions, said: “We had high expectations for the ME-GA upon its launch as we recognised a strong desire – primarily from the LNG carrier market – for an alternative to our successful ME-GI engine. Judging alone by the fact that ME-GA has won references from all three major shipyards in Korea, these expectations have been met and even exceeded.” As its pre-mixed combustion results in low NOx emissions, the ME-GA engine is inherently Tier II and Tier III compliant in gas-operation mode. EGR enables the significant reduction of methane slip, while simultaneously improving fuel efficiency in both gas and fuel-oil operation. Ultimately, EGR actively reduces emissions and improves efficiency in both Tier II and Tier III.MAN Energy Solutions aims to start testing the first, commercial ME-GA design by the end of this year, with the first engine delivery scheduled for early 2022.The MAN B&W ME-GA engine delivers a low CAPEX solution aimed at certain vessel types and applications, such as LNG carriers, that are able to use ‘boil-off’ gas as a source of fuel. It could also be of appeal to smaller vessels 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 unique gas-admission system that delivers safe and reliable operation. The ME-GA furthermore features minimal operational costs, simple supply and purging concepts, and low maintenance costs for its fuel-gas supply system. With Tier III compliance in gas mode, the engine meets all current and upcoming NOx emission regulations with the addition of EGR. The ME-GA joins the well-established ME-GI Diesel-cycle engine in MAN Energy Solutions’ two-stroke-engine portfolio, which now offers both low- and high-pressure, dual-fuel solutions for operation on LNG.
