Doosan Engine has confirmed delivery of what it refers to as "the world’s first dual-fuel, low-speed ME-GI engine" to the
American National Steel and Shipbuilding Company (NASSCO) shipyard in San Diego, USA.
The new engine is capable of operating on LNG and/or bunker C oil and will power the first of two 3,100-teu container ships ordered by
TOTE, the American marine transportation company.
The Korean engine maker originally won the order to build the
MAN Diesel & Turbo ME-GI engines in 2013, since which time the first ME-GI unit has passed through design, manufacture, and test-run stages.
On 3 June 2014, Doosan Engine 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 was deeemd to have 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 contract
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.
According to MAN Diesel & Turbo, the two 3,100 TEU vessels will be "the most environmentally friendly containerships in the world", powered primarily by LNG, and will operate between
Florida and
Puerto Rico. The ship design will allow the transport of conceivable products.
The ME-GI engine
The ME-GI engine represents the culmination of many years’ work. Depending on relative price and availability, as well as environmental considerations, the ME-GI engine gives shipowners and operators the option of using either heavy fuel oil (HFO) or gas – predominantly natural gas. An ME-LGI counterpart is also being developed that uses
liquefied petroleum gas (LPG) and
methanol.
MAN Diesel & Turbo says it sees significant opportunities arising for gas-fuelled tonnage as fuel prices rise and modern exhaust-emission limits tighten.
"Research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions. Furthermore, the ME-GI engine has no methane slip and is therefore the most environmentally friendly technology available. As such, the ME-GI engine represents a highly efficient, flexible, propulsion-plant solution," MAN Diesel & Turbo said.
