Qatargas was established in 1984 as one of the main vehicles to develop the extensive offshore North Field.

By 2010 it will be exporting approximately 42 million tonnes per annum (mtpa) of liquefied natural gas (LNG) to markets in Europe, Asia and the North America.
Qatargas began as a project with three trains of two mtpa capacity. 
Following the successful completion of a debottlenecking project in 2005 the capacity of the trains increased to 9.7 mtpa.
In 2005 Qatargas celebrated the delivery of its 1000th cargo.  Today, Qatargas has a fleet of 11 ships which services customers in Japan and Europe. 
In 2007 Qatargas celebrates its 10th anniversary of operations.  During this time Qatargas has achieved many milestones whilst continuing to be a reliable supplier of clean energy to its customers in Japan and Spain as well as providing spot cargoes to France, Italy, Turkey and the United States to name a few. 
During these past 10 years and into the future, the company’s commitment to reliability, customer satisfaction and improving its safety performance have been the cornerstones of its success and will continue to be so during the expansion and start-up of the new trains.
Currently, the Company is undergoing a period of rapid expansion.  There are three projects under way, which will add an additional four trains. 
These projects are being developed in partnership with the leading companies in the industry including ExxonMobil, Total, ConocoPhillips, Shell and Mitsui. 
The expansion projects include the development of a new fleet of LNG ships, the installation of six offshore platforms, and the development of a receiving terminal in Milford Haven with associated pipeline infrastructure and extension of the existing Port facilities.
Each of the four new trains will have a capacity of 7.8 million tonnes per year.  The two trains of Qatargas 2 will serve predominantly the United Kingdom’s gas market.  Qatargas 3 and Qatargas 4 will supply LNG to Europe and the United States.
The fleet of new LNG ships which are currently being built in Korea are known as Q-Max and Q-Flex.  This new generation of LNG ships will be up to 80 per cent bigger than the current LNG ships that Qatargas uses. 
With a cargo capacity of between 210,000 and 266,000 the new ships deliver economies of scale in the transporting of LNG to Europe and the United States.
In addition, Qatargas is constructing a condensate refinery, Laffan Refinery to maximise synergies in the production of LNG and other related products.
