MAN Diesel & Turbo’s 6-cylinder S70ME-GI dual-fuel low-speed engine (graphical rendition)
Knutsen OAS Shipping, a Norwegian shipping company, has placed an order for 2 × 2 7G70 ME-GI engines in connection with the building of two 176,300 m3 capacity LNG carriers. Depending on relative price and availability, as well as environmental considerations, the ME-GI engine gives shipowners and operators the option of using either HFO or gas – predominantly natural gas. To date, MAN Diesel & Turbo has clinched orders for 42 dual-fuel units, representing a power output of 780 MW.
Within the company’s low-speed engine portfolio, the ME-GI engine is officially designated as ME-C-GI (M-type, Electronically Controlled, GI for Gas Injection).
MAN Diesel & Turbo has verified that, even when compared to the best modern Dual Fuel Diesel Electric (DFDE) propulsion solution, an ME-GI engine delivers fuel savings of more than 30 tonnes of gas per day when operating at a normal ship speed of 15-17 knots. The environmentally friendly ME-GI engine also delivers significant reductions in CO2, NOx and SOx emissions without any methane slip.
MAN Diesel & Turbo sees significant opportunities arising for gas-fuelled tonnage as fuel prices rise and modern exhaust-emission limits tighten.
