Hyundai’s Ship-Building Division, HHI-SBD, has ordered 8 × MAN B&W 8G95ME-LGIM (Liquid Gas Injection Methanol) engines, in connection with the building of 8 × 16,000-teu container ships for A.P. Moller – Maersk, the global integrator of container logistics. Hyundai Engine & Machinery Division, HHI-EMD, will build the engines. The order contains an option for a further four engines, with the first of the confirmed vessels due to enter service in Q1, 2024. Methanol dual-fuel engines Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business, MAN Energy Solutions, said “This is a massive milestone, as these engines will be the largest methanol-burning engines ever constructed. They will be based on their well-proven 50-bore counterpart, which has already been in our engine portfolio for some time, gathering more than 100,000 running hours on methanol alone.” Bjarne Foldager adds, “The 95-bore’s development is another example of our commitment towards decarbonisation and providing solutions demanded by the market.” MAN Energy Solutions MAN Energy Solutions states that the new engines will be capable of burning bio-methanol MAN Energy Solutions states that the new engines will be capable of burning bio-methanol, as well as e-methanol. The new order closely follows that from July 2021, when MAN Energy Solutions won the order to supply the world’s first, low-speed, dual-fuel engine to run on methanol, within the container segment – a MAN B&W 6G50ME-LGIM type built by HHI-EMD – to a 2,100-teu vessel also ordered at Hyundai Mipo Dockyard, by A.P. Møller – Maersk. Thomas S. Hansen, Head of Promotion and Customer Support, MAN Energy Solutions, said “As a fuel, methanol is quickly becoming an option within the large container-vessel segment where, up until now, conventional fuel and LNG have long reigned.” Switching to methanol as fuel in other ship segments Thomas Hansen adds, “We expect that this significant order will spur further market interest in methanol as a fuel, also within other ship segments, such as bulkers. Our other ME-LGIM references show methanol to be a clean, efficient and safe, marine fuel that offers a clear path to decarbonisation, through significant greenhouse-gas reductions, when produced from renewable energy sources.” Brian Østergaard Sørensen, Vice President, Head of Research & Development, Two-Stroke at MAN Energy Solutions, said “We have developed the G95 LGIM technology at our R&D test centre, in Copenhagen, based on the extensive knowledge and experience within dual-fuel technology that we have built up, over the past decade.” MAN Energy Solutions’ dual-fuel engine portfolio Brian Østergaard Sørensen adds, “In general, as we move towards a zero-carbon future, MAN Energy Solutions’ dual-fuel engine portfolio is well positioned, to handle whatever challenges the market brings.” MAN Energy Solutions states that its low-speed, dual-fuel references now exceed 466 units, with its ME-GI type recording over 1.8 million operating hours on LNG alone, while the ME-LGI platform has accumulated more than 110,000 dual-fuel running hours. MAN B&W ME-LGIM engine MAN Energy Solutions developed the ME-LGIM dual-fuel engine for operation on methanol MAN Energy Solutions developed the ME-LGIM dual-fuel engine for operation on methanol, as well as conventional fuel. The engine is based on the company’s proven ME-series, with its approximately 5,000 engines in service, and works according to the diesel principle. When operating on methanol, the ME-LGIM significantly reduces CO2, greenhouse gas, particles, NOx and SOx emissions. Additionally, any operational switch between methanol and other fuels is seamless. Tests on the engine, when running on methanol, have recorded the same or slightly better efficiency, when compared to conventional, HFO-burning engines. High fuel efficiency MAN Energy Solutions developed the ME-LGI engine, in response to interest from the shipping world, in operating on alternatives to heavy fuel oil. Methanol carriers have already operated at sea for many years, using the engine and as such, the ME-LGIM has a proven track record, offering great reliability, in combination with high fuel efficiency.
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. Authority Comments 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.” 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.” Operation and testing EGR enables the significant reduction of methane slip while improving fuel efficiency in both gas and fuel-oil operation 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. ME-GA engine comes with EGR as a standard owing to its performance and environmental benefits 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 after treatment. 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 a standard.
