Doosan Engine has confirmed the delivery of the world’s first dual-fuel, low-speed ME-GI engine to the American National Steel and Shipbuilding Company shipyard in San Diego, USA. The new engine is capable of operation on LNG and/or bunker C oil and will power the first of two 3,100-teu containerships ordered by TOTE, the American marine transportation company.
The Korean engine maker originally won the order to build the ME-GI engines in 2013, since which time the first ME-GI unit has successfully passed through design, manufacture, and test-run stages. On 3 June 2014, Doosan Engine successfully completed the engine’s official trial run in the presence of the shipowner, shipyard, and classification society representatives.
Doosan Engine also tested the ME-GI’s Fuel Gas Supply System (FGSS), which has 300 bar of operating pressure, at its Changwon plant. At the culmination of two months of extensive testing, the gas system had passed all regulations and restrictions as regulated by the American Bureau of Shipping (ABS) and United States Coast Guard (USCG).
The TOTE ME-GI engine will primarily operate on LNG, which is currently more competitively priced than bunker-C oil. The ME-GI is a next-generation, eco-friendly engine, which reduces polluted material such as carbon dioxide, nitrogenous compound, and sulphur compounds compared to existing diesel engines.
The TOTE contract provides for the construction of two newbuilding, state-of-the-art containerships – with an option for three more vessels – for primarily domestic services. The vessels will each be powered by a single 8L70ME-GI dual-fuel gas-powered engine.
