The consortium was one of three groups competing for the engineering, procurement and construction (EPC) award. The others were: Paris-based Technip, with Turkey’s Gama; and Italy’s Techint, with the US’ Black & Veatch Oil, Gas & Chemicals.

Washington Group will carry out detailed engineering in its Denver and Bucharest offices. Overall project completion is set for late 2008, with an intermediate start-up set for 2007.

The expanded facility will serve several oil and gas ventures based at Ras Laffan. With liquefied natural gas (LNG) exports expected to triple and gas-to-liquids (GTL) capacity set to soar, sulphur production is forecast to rise six-fold to an estimated 12,000 million t/d by 2010.
