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.
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. These design merits have made the engine the standard propulsion system for the LNG-fuelled fleet.
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-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.
