MAN B&W Diesel to Power New LNG carriers

Posted on April 18, 2006

The Shipping Requisition Team has confirmed orders for six Q-max LNG carriers. Each vessel will be powered by two MAN B&W Diesel 7S70ME-C electronically controlled, two-stroke, low speed diesel engines. These vessels will reportedly be the world’s largest LNG carriers, each able to transport 265 000 cubic meters of LNG. The vessel will operate with a reliquefaction plant for operation of boil off gas to the cargo tanks.

All 12 MAN B&W Diesel 7S70ME-C engines will be built by the Doosan Engine Co. Ltd. of Korea. Each main engine is rated at 21 770 kW at 91 r/min. Each vessel will also be fitted with four MAN B&W Diesel 9L32/40 Holeby GenSets. The 24 gen-sets will be built by the STX Corporation.

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