MAN B&W Diesel to Power LNG Ships
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 cu. m. 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%).
