Abu Dhabi Oil Refining Company (Takreer) has finalised contracts for the main construction packages on its Ruwais refinery expansion with four South Korean firms.

The engineering, procurement and construction contracts for five packages of the refinery expansion were awarded in November 2009.

A final agreement was signed with GS Engineering & Construction for the $3.1bn deal to build the residual fluid catalytic cracker on 3 March, according to Takreer. GS also signed a $500m deal to build marine facilities.

Samsung Engineering has signed a $2.7bn contract to build the offsites and utilities. Meanwhile SK Engineering & Construction has signed a $2.1bn deal to build the main crude distillation and downstream units.

Takreer has also signed a deal with Daewoo Engineering & Construction Company for the $1.2bn deal to build the tankage and associated interconnecting piping package.

The deals are part of Takreer’s plans to expand the production capacity of the Ruwais refining complex from 417,000 barrels a day (b/d) to 817,000 b/d. The expansion is scheduled for completion in 2013 and the work involved in the project is worth more than $10bn in total.

The refinery will be integrated with neighbouring petrochemical complexes and will supply about 1.1 million tonnes of propylene to the Abu Dhabi Polymers Company (Borouge) plastics complex at Ruwais.
