Teekay's first MEGI-powered LNG tanker completes first year


Fuel consumption of MEGI vessels is said to be lower than most DFDE propulsion systems.

Teekay's first M-type, electronically controlled, gas injection (MEGI)-powered liquefied natural gas (LNG) vessel, the Creole Spirit, completed its first year in operation on 17th February.

The vessel, which was initially floated out at the Daewoo Shipbuilding & Marine Engineering (DSME) shipyard in South Korea on 29th May 2015, has been on charter contract with Cheniere Marketing since February last year.

Commenting on the vessel's fuel efficiency in 2016, Teekay noted: "The two-stroke engine technology provided by MAN Diesel, the MEGI propulsion system, is driving a step change in global LNG vessel efficiency. Whilst the most efficient dual-fuel, diesel-electric (DFDE) propulsion systems have daily consumptions in the region of 125 to 130 tonnes including sea margin, the MEGI vessels have a consumption of 100 tonnes."

In addition to the lower fuel consumption, the vessel's two-stroke technology is said to also offer a reduction in the number of cylinders requiring overhaul, a reduction in the size of the complex electrical systems and the introduction of a passive partial reliquefaction system - designed to improve efficiency and further help to reduce the unit freight cost.
