Methane-Fuelled ME-GI Engines Lead Way With Lowest Methane Slip

  • The dual-fuel low-speed electronically controlled MAN B&W ME-Gl two-stroke engine is the most efficient marine gas engine in the portfolio of MAN Energy Solutions and on the market, capable of running on conventional and alternative fuels.
  • With relatively low fuel prices and an existing advanced network of bunkering stations in many ports around the world, LNG has become a very attractive option for new buildings and retrofit projects.
  • Most ME-C engines in the Marine Engine Programme of MAN Energy Solutions can be offered as dual-fuel ME-Gl gas engines, thereby ensuring that all ship types can be converted to dual-fuel operation.

Times Shipbuilding Co. Ltd. of Jiangsu province, China has ordered 12 × 8G95ME-GI (-Gas Injection) Mk10.5 main engines in connection with the construction of 12 × 18,000 teu container vessels for Eastern Pacific Shipping (EPS), reads a MAN-ES release.

Bjarne Foldager – Country Manager, Denmark – MAN Energy Solutions, said: “This new, sizable order reflects the great momentum the ME-GI engine has experienced during the building boom that the Very Large Container Vessel segment is currently experiencing. EPS is an old acquaintance of MAN Energy Solutions with whom we have built an excellent relationship over the years. This is just the latest in a series of mutual, recent ME-GI projects and we thank them for placing their trust in us again.”

Thomas S. Hansen – Head of Two-Stroke Sales and Promotion – MAN Energy Solutions, said: “The ME-GI’s mature technology brings a number of advantages to the table, not least its guaranteed, extremely low levels of methane slip that make it the most future-proof methane engine on the market. It also has the highest fuel efficiency in its class, which explains why the G95ME-GI Mk10.5 has been specified for more than 60 Very Large Container Vessel newbuilds in just the past two months. The ME-GI is furthermore capable of operating on bio-methane and synthetic natural gas that render it net-zero and provide a viable decarbonisation pathway for shipowners.”

The ME-GI engine – the industrial standard

MAN Energy Solutions successful ME-GI (-Gas Injection) engine has set a new industrial standard for two-stroke propulsion engines aboard – among others – RoRo vessels, PCTCs, container vessels, bulk carriers, tankers and LNG carriers. The ME-GI engine provides ship owners, charterers and operators with a peerless solution within environmentally friendly and high-efficiency, two-stroke technology but without the prominent methane-slip emissions that are characteristic of competing engines.

The Diesel principle not only provides the ME-GI engine with high operational stability and efficiency, but also ensures 100% reliable operation during load changes on gas with just normal additions of pilot-oil amounts. Furthermore, the ME-GI operational principles features a seamless change-over between gas and diesel operation. The ME-GI engine is the most environmentally-friendly technology available within the LNG-fuelled, two-stroke engine segment.

MAN Energy Solutions has also developed an ME-LGI (-Liquid Gas Injection) dual-fuel engine that expands the company’s dual-fuel portfolio, enabling the use of sustainable fuels such as green methanol.
