Korean engine builder Doosan Engine has delivered the first dual-fuel, low-speed ME-GI engine to the NASSCO shipyard in San Diego for the first of two 3,100teu container ships ordered by US operator TOTE.

The engines were ordered from MAN Diesel & Turbo licensee Doosan in 2013, since which time the first ME-GI unit has successfully passed through design, manufacture, and test-run stages. Doosan Engine also tested the ME-GI’s 300 bar fuel gas supply system at its Changwon plant. After two months of extensive tests, the system passed all ABS and the US Coast Guard regulations.

The TOTE ME-GI engine will primarily operate on LNG, which is currently more competitively priced than bunker-C oil in the US. The contract provides for the construction of two newbuild container ships – with an option for three more vessels – for primarily domestic services. Each will be powered by a single 8L70ME-GI dual-fuel engine. This, says MAN Diesel & Turbo, will make them the most environmentally friendly containerships in the world.

MAN Diesel & Turbo says it sees significant opportunities arising for gas-fuelled tonnage as fuel prices rise and modern exhaust-emission limits tighten, and its ME-GI technology is well placed to deliver substantial reductions in NOx and SOx emissions as well as significantly lower greenhouse gas emissions as the high-pressure gas system eliminates methane slip.
