Paris-based Litwin has won an estimated $20m engineering, procurement and construction (EPC) contract to improve the quality of the gasoline Abu Dhabi Oil Refining Company (Takreer) produces at its Ruwais refinery complex.

The company submitted the lowest price for the deal in a 14 March bid round and was formally awarded the contract in early April, sources close to the scheme tell MEED.

The contract covers the construction of facilities to process high-octane gasoline products. Takreer has called the scheme, the isomerate quality improvement project.

Spain’s Tecnicas Reunidas completed the front-end engineering and design on the project in late 2009. Contractors value the project at about $20m.

At least five companies were prequalified to bid on the deal, including Italy’s Saipem, Paris-based Technip and Germany’s Uhde, according to sources close to the scheme (MEED 17:3:2010).

Abu Dhabi has spent more than $10bn on schemes to increase the volume and quality of the refined oil products it produces at the Ruwais complex in the past year. The state refiner awarded $9.6bn of EPC deals in November 2009 as part of a major new scheme to boost the refinery’s output by 400,000 barrels a day (b/d).
