MAN B&W power for Q-Max LNG ships

The world's largest LNG carriers will each be powered by two MAN B&W Diesel 7S70ME-C electronically controlled two-stroke low speed diesel engines.

The ships are the six 265,000 cu.m Q-max LNG carriers ordered by Qatargas II from Daewoo Shipbuilding and Marine Engineering in Korea.

Qatargas II is a joint venture between Qatar Petroleum (70%) and ExxonMobil (30%).

All 12 of the 7S70ME-C engines will be built by the Doosan Engine Co. Ltd. (Korea). Each main engine is rated at 21,770 kW at 91 rpm.

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 (Korea).

The vessels will each be equipped with a reliquefaction plant.

Including projected vessels--six Q-max and four Q-Flex--this order brings to 36 the total number identified LNG tankers 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 each are now on order or delivered for installation in LNG carriers.
