Qatargas 3 - Economies of scale

The Qatargas 3 (QG3) project involved the construction of a new LNG mega-train (Train 6) with a capacity of 7.8 million tonnes per annum (MTA). Production from Train 6 started in November 2010.
The LNG produced by QG3 is transported to market on a fleet of ten ships each with a capacity of approximately 210,000 - 266,000 cubic metres. The upstream platforms and infrastructure consist of three unmanned platforms, 33 wells and two subsea pipelines, all of which are shared with the Qatargas 4 project. Qatargas 3 produces 1.4 billion standard cubic feet of gas per day, delivering LNG and substantial volumes of condensate and LPG.

Qatargas 3 utilises the same Air Products proprietary APX process technology as Qatargas 2. This helps to achieve economies of scale and integration which puts Qatargas ahead of its competitors. The Qatargas 3 and Qatargas 4 projects were developed and executed by a Joint Asset Development Team to capture synergies between the two projects.

QG 3 Train 6 ships its LNG predominantly to the United States, Asia and Europe. At full operational capacity, the train is capable of providing approximately one billion cubic feet of gas per day for 25 years.
