KBR, a US construction company, won an engineering and project management contract for a planned 400,000 barrel-a-day refinery at Jazan in Saudi Arabia from state oil producer Saudi Aramco.

Aramco is developing the $7 billion project to meet domestic demand for refined products and boost economic growth. The value of the KBR contract wasn’t revealed.

Aramco is building the refinery at a planned industrial area and port on its southwest Red Sea coast.

KBR will complete an engineering and design study for the refinery and port facilities, conduct the bidding process for building the plant and oversee construction.

The facility will process 250,000 to 400,000 barrels of crude a day.

The Jazan refinery is one of three new plants that Aramco is building in the kingdom. Aramco is looking for partners to develop a 400,000 barrel-a-day refinery at Yanbu on the Red Sea coast and is working with Total SA to build a $12 billion, 400,000 barrel-a-day refinery and chemical project at the Jubail industrial city on the Gulf coast.
