Teekay LNG Partners L.P. (Teekay LNG) has entered into two, five-year time-charter contracts with Cheniere Marketing, LLC (Cheniere) to provide them with Liquefied Natural Gas (LNG) transportation services using ships powered by MAN MEGI gas injection engines.

The fixed-rate time-charter contracts will be serviced by the two 173,400 cubic meter LNG carrier newbuildings ordered by Teekay LNG in December 2012. The newbuildings are currently under construction by Daewoo Shipbuilding & Marine Engineering of South Korea and are scheduled to be delivered in the first half of 2016. The newbuildings will be constructed with M-type, Electronically Controlled, Gas Injection (MEGI) twin engines, which are designed to be significantly more fuel-efficient and have lower emission levels than other engines currently being used in LNG shipping.

“We are excited to be supporting Cheniere, which will be exporting volumes from the Sabine Pass LNG export facility, the first LNG export facility project in the contiguous United States to receive approval for LNG exports,” commented Peter Evensen, Chief Executive Officer of Teekay GP LLC. “This is a pioneering transaction which combines one of the first U.S. LNG export facilities with the first MEGI-propelled LNG carriers to be chartered.”

MAN Diesel’s publication — LNG Carriers with ME-GI Engine and High Pressure Gas Supply System — states a tailor-made ME-GI propulsion solution together with a fuel gas supply system optimises the key application issues such as efficiency, economy, redundancy and safety. Utilizing boil-off gas, the high-pressure gas injection system offers the advantage of being almost independent of gas/oil fuel mixture, as long as a small amount of pilot oil fuel is injected for ignition.

On a laden voyage, MAN estimates boil-off gas equals about 80-90 % of fuel requirements, and in ballast voyage 40-50 % of the energy needed for the LNG vessel operating at full power. Additional gas could be generated by forced boil-off. In an LNG carrier having an LNG storage tank which is thermally-insulated, as heat is continually transmitted from the outside to the LNG in the LNG storage tank, the LNG is continually vaporized and boil-off gas is generated in the LNG storage tank during the voyage.
