DEMAND FOR LOW METHANE SLIP BRINGS MARKET SUCCESS FOR MAN B&W ME-GA WITH EGR

DEMAND FOR LOW METHANE SLIP BRINGS MARKET SUCCESS FOR MAN B&W ME-GA WITH EGR

Friday, August 20, 2021 

MAN Energy Solutions has announced that its MAN B&W ME-GA engine the low-pressure version of its dual-fuel two-stroke engine has landed 40 orders since its market launch.

The company originally concentrated on the high-pressure diesel-cycle ME-GI for LNG-fuelled marine propulsion applications, but announced the low-pressure Otto-cycle alternative in March 2021. Although commercial deliveries are not scheduled to start until early 2022 , the engine has attracted a surge of orders, primarily from the LNG carrier sector. The company attributes the success to the increased focus in the market on methane slip, brought about by demand for lower levels of greenhouse gas emissions.

Bjarne Foldager, SVP 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.” 

Thomas S Hansen, Head of Promotion and Customer Support, MAN Energy Solutions, said: “As industry leaders committed to lowering emissions, the ME-GA comes with our high-pressure EGR as standard, a technology we have refined over the past decade. The increased focus on methane-slip reduction – as well as other operational/technical benefits – has established EGR technologies as the new standard for contemporary LNG-carrier design featuring Otto-cycle engines.”

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.

Foldager added: “The ME-GA engine is just MAN Energy Solutions’ latest initiative to decarbonise shipping and further the maritime energy transition to sustainable fuels. Our dual-fuel engines continue to act as standard bearers for environmentally-friendly, reliable propulsion-technology with their seamless switching between fuels. Ultimately, we expect the ME-GA to become standard among LNG carriers.”

Based on the proven MAN B&W dual-fuel design, the ME-GA uses an efficient ignition concept and specially-developed gas-admission system that delivers safe and reliable operation. Operational costs are expected to be low, with simple supply and purging concepts and low maintenance costs for its fuel-gas supply system.
