Teekay celebrates MEGI vessel keel laying

LNG Industry,

Teekay has marked the keel laying ceremony of the Creole Spirit LNG carrier, the first of nine vessels powered with MEGI twin engines.

The newbuildings are currently under construction by Daewoo Shipbuilding & Marine Engineering (DSME) and are due for delivery in 2016, on a charter contract with Cheniere.

The project is already taking shape and approximately 60 000 insulation blocks per ship were installed temporarily for the assembly of the cargo containment system.

MEGI engine

Approximately 10 days after the keel laying ceremony, the M-type, Electronically Controlled, Gas Injection (MEGI) engine was installed on the Creole Spirit. Teekay is the first ship owner to order a MEGI-propelled LNG carrier, which are designed to be more fuel-efficient and have lower emission levels than other engines currently being used in LNG shipping.

The heart of the MEGI engine consists of a Burckhardt compressor and partial reliquefaction system. The compressor will take the boil-off gas (BOG) from the cargo tanks and compress it to 300 bar for direct injection into the MEGI engine. The partial reliquefaction will take any of the excess gas not used by the engine and return it to a liquid state to put back into the cargo tank by dropping the excess gas pressure from 300 bar to 3 bar in a pair of Joule Thomson valves.
