TRAIN 6

TRAIN 6: THE COMPANY’S FIRST IN A NEW GENERATION OF LNG MEGA-TRAINS, EACH CAPABLE OF PRODUCING 7.8 MTA OF LNG

RasGas Train 6 produced its first LNG in July 2009. The following month its first cargo, a 212,000m3 shipment of LNG, was loaded aboard the RasGas Q-Flex tanker Al Utouriya. The new train was formally inaugurated in October 2009. The start-up of Train 6 boosted RasGas’ LNG production capacity to 28.5 Mta.

Train 6 forms part of the RasGas Expansion Phase 2 Project (RGX2), a multi-billion dollar expansion project that brought the company’s LNG production capacity to approximately
37 Mta in 2010, with the completion of seven operational trains.

The mega-trains build on the success of existing RasGas expansion projects in terms of technology, design, project specifications, existing infrastructure and location. Train 6 is fed by an expansion to RasGas’ offshore facilities that also serves Train 7, including two offshore 12-well platforms and two 100km 38-inch export pipelines to the shore.

Each pipeline has an eventual transmission capacity of up to 2.1 Bscfd. Helium recovered from the raw input stream will supply a second Qatar helium refining plant.

RasGas’ strong relationships with contractors have helped it to maximise performance and to learn through continuous improvement. For example, from the time construction of Train 6 was completed, just 45 days passed before it produced its first LNG.

Through full engagement of both company and contractor leadership, RasGas project management has developed a structured and disciplined safety management approach that has generated world-class results in safety performance. RasGas’ goal is an incident-free workplace and the safety results of the Train 6 and Train 7 projects are a true step in that direction.

Train 6 in numbers

The primary process equipment for Train 6 occupies 14 hectares and rises to 59 metres in height. The heaviest machinery (an amine absorber, which removes hydrogen sulphide and carbon dioxide) weighs 1,286 tonnes.

The rate of flow of sour feed gas (raw material) to Train 6 is 1,450 Mmscfd and its daily outputs are:

  • Lean LNG – 23,000 tonnes
  • Field condensate – 48,000 barrels
  • Plant condensate – 7,000 barrels
  • Propane –1,300 tonnes
  • Butane – 800 tonnes
  • Molten sulphur – 466 tonnes
