MAN To Power Norwegian LNGCs
Market adoption of dual-fuel, low-speed engines grows
Norwegian shipping company Knutsen OAS Shipping has placed an order for four MAN Diesel & Turbo 7G70ME-GI engines to power (two engines per vessel) two new 176 300 m3 capacity LNG carriers.
MAN said the engines are based on its ultra-long-stroke, G-type concept, which can deliver fuel savings of more than 30 tonnes/dy of gas when operating at a normal ship speed of 15 to 17 knots.
The ME-GI engine gives shipowners and operators the option of using either heavy fuel oil (HFO) or gas (predominantly natural gas), the company said, adding that an ME-LGI counterpart that uses LPG and methanol is being developed.
MAN research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions. Furthermore, the company said the ME-GI engine has no methane slip and is environmentally friendly.
Hyundai became the first MAN Diesel & Turbo two-stroke licensee to demonstrate the ME-GI concept in Korea in late-2012, with Mitsui following in April 2013.
