MAN sees ‘surge’ in orders for ME-GA engine

LNG carrier demand high
MAN Energy Solutions said it has landed 40 orders for its MAN B&W ME-GA engine – the latest addition to its dual-fuel portfolio –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.
“We had high expectations for the ME-GA upon its launch as we recognized a strong desire – primarily from the LNG carrier market – for an alternative to our successful ME-GI engine,” said Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business, MAN Energy Solutions. “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 the ME-GA comes with high-pressure EGR as standard, a technology the company has 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,” Hansen said.
As its pre-mixed combustion results in low NOx emissions, the ME-GA engine is inherently Tier 2 and Tier 3 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, the company said.
“The ME-GA engine is just MAN Energy Solutions’ latest initiative to decarbonize shipping and further the maritime energy transition to sustainable fuels,” Foldager said. “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.”
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 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 3 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.
