South Korean shipyard Hanwha Ocean Co. Ltd., has ordered 4 × MAN B&W 5G70ME-GI Mk10.5 engines in connection with the construction of 2 × 174,000 cbm LNG carriers for an undisclosed shipowner. Hanwha Engine Co. Ltd. will build the engines in South Korea and the contract contains an option for two additional vessels. Each engine will come integrated with MAN Energy Solutions’ proprietary EGRBP (Exhaust Gas Recirculation ByPass) system.

To date, we have achieved a total of more than 890 ME-GI references, either on order or in service, with over 110 of those within the LNGC segment alone. The ME-GI engine has several favourable characteristics, including a best-in-class performance, the highest thermal efficiency for methane-fuelled two-stroke engines, as well as millions of reliable operating hours. The ME-GI—not being sensitive to fuel properties—is furthermore capable of operating on bio-methane and synthetic natural gas that render it net-zero, providing a viable decarbonization pathway for shipowners.

The ME-GI engine provides ship owners, charterers and operators with a solution within 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’s operational principles feature a seamless change-over between gas and diesel operation. The ME-GI engine is the most environmentally-friendly technology available within the LNG-fueled, two-stroke engine segment, the company said.

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.
