Spanish engineering company Tecnicas Reunidas S.A. (TRE.MC) Monday confirmed that it won a contract to design and build the destillery and water treatment plants of a planned refinery on Saudi Arabia's Persian Gulf coast.

The contract, worth roughly EUR1.2 billion, is one of 13 that were awarded by a joint venture of Saudi Arabian Oil Co. and Total S.A. (TOT) of France.

The refinery project, called Saudi Aramco Total Refining and Petrochemical Co., or Satorp, has a total budget of $9.6 billion.

The joint venture last Thursday said Tecnicas Reunidas had been selected for the contract, along with France's Technip SpA (TEC.FR), and several South Korean companies.

The refinery will have a capacity of 400,000 barrels a day and is scheduled to be fully operational by the second half of 2013.
