MAN B&W powers largest LNG carriers

MAN B&W Diesel has received a contract to supply slow speed diesel engines for the six 265,000 m3 Q-max LNG carriers ordered by Qatargas II from Daewoo Shipbuilding and Marine Engineering in Korea. These vessels will be the world?s largest LNG carriers and each vessel will be powered by two MAN B&W Diesel 7S70ME-C electronically controlled two-stroke low speed diesel engines.

The vessel will operate with a reliquefaction plant for operation of boil off gas to the cargo tanks. All twelve engines will be built by Korea?s Doosan Engine company. Each main engine is rated at 21,770 kW at 91 rpm and each vessel will also be fitted with four MAN B&W Diesel 9L32/40 Holeby Gensets. The 24 gensets will be built by the STX Corporation in Korea.

Including projected vessels, six Q-max and four Q-Flex, this order brings the total number of identified vessels up to 36 for LNG carriers with MAN B&W Diesel two-stroke engines operating on HFO in conjunction with reliquefaction plants. In total, 72 MAN B&W Diesel S70ME-C engines with 6 or 7 cylinders are now on order or delivered for installation in LNG carriers.
