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 be the
world’s largest LNG carriers, each able to transport 265,000 m3 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. (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).
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%).
The engines of choice for LNG carriers are either 6 or 7 cylinder versions of the MAN B&W Diesel two-stroke, electronically controlled S70ME-C. These engines are used in a variety of applications where flexibility and reliability are essential for uninterupted vessel operation.
