    New engine standard arises for LNG carriers as increased focus on methane-slip drives new orders for low-pressure, dual-fuel engine and accompanying EGR

    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, according to the company's release. 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.

    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.”

    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.

    About ME-GA

    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.

    About EGR

    In November 2020, MAN Energy Solutions announced that it would offer its proprietary EGR (Exhaust Gas Recirculation) system as an emissions solution for the ME-GA. EGR is a NOx-emissions-reduction technique that ensures IMO Tier III-compliance in diesel mode for the ME-GA.

    The company reports that EGR will enable the ME-GA to reduce specific gas consumption by ~3%, and specific fuel-oil consumption by 5%. It will also significantly reduce methane slip by 30 to 50%, and improve the stability of the Otto-cycle combustion process. EGR will enable the ME-GA to meet Tier III requirements in both fuel oil and gas modes without additional aftertreatment.

    The ME-GA EGR solution is an engine-integrated design that interacts with the exhaust gas before the turbocharger, and can be integrated into existing engine-room designs since the EGR unit itself does not change the engine footprint. Its design-similarity to that of ME-C engines’ EGR systems will lower its price point, since the supply chain and components are already matured.

    The volume requirements of the ME-GA EGR system are also significantly lower with, for example, less pipework required than for low-pressure EGR solutions.

    Due to its performance and environmental benefits, each ME-GA engine comes with EGR as standard.
