MAN Energy Solutions experiences that its first ME-GA Otto-cycle engine has accomplished gasoline trials in an LNG provider constructed by Hyundai Samho Heavy Industries (HSHI) for Norwegian delivery firm, Knutsen OAS Shipping.
“This successful gas trial is a very important milestone in the development of the ME-GA engine,” mentioned Bjarne Foldager, head of two-stroke enterprise at MAN Energy Solutions. “We developed this engine for easy application to most contemporary LNG carrier designs and, indeed, all ME-GA orders to date have been exclusively for this segment.”
Built by HHI-EMD, the Knutsen ME-GA engine is supplied with exhaust gasoline recirculation (EGR) which reduces methane-slip emissions in comparison with first-generation, Otto-cycle engines with out EGR.
“We have had more than 260 orders for the ME-GA since its launch in May 2021 and our orderbook contains ME-GA engine orders for ship deliveries stretching all the way into 2027,” mentioned Brian Østergaard Sørensen, vp and head of R&D, two-stroke enterprise at MAN Energy Solutions. “EGR as standard enables the ME-GA to significantly reduce emissions, while simultaneously improving fuel efficiency and operation in both gas and fuel-oil operation.”
“It’s been very pleasing to follow the steady progress of the ME-GA engine ever since we began its development back in 2018,” mentioned Thomas S. Hansen, head of promotion and buyer assist at MAN Energy Solutions. “Following its Factory Acceptance Test, Type Approval Test and first shipyard delivery, this completion of sea- and gas-trials marks another significant step in its timeline as it approaches its commercial debut.”
LOW CAPEX SOLUTION FOR LNG CARRIERS
The MAN B&W ME-GA engine delivers a low CAPEX resolution geared toward LNG carriers which might be ready to make use of ‘boil-off’ gasoline as a supply of gas.
Based on the well-proven MAN B&W dual-fuel design with minimal set up necessities, the MAN B&W ME-GA makes use of an environment friendly ignition idea and distinctive gas-admission system designed to ship protected and dependable operation.
Other options of the ME-GA are minimal operational prices, easy provide and purging ideas, and low upkeep prices for its fuel-gas provide system. It joins the well-established ME-GI Diesel-cycle engine in MAN Energy Solutions’ two-stroke-engine portfolio, which now affords each low- and high-pressure, dual-fuel options for operation on LNG.
