A joint venture (JV) company will be formed between Saudi Arabia-based AYTB and KBR to carry out the maintenance work at the SATORP refinery for seven years.

The value of the contract will be between $140m to $170m, depending upon the services.

Under the contract, the JV will provide overall site management services and field supervision for mechanical, electrical and instrumentation.

AYTB CEO Abdulmohsen Al-Ogaili said, "This GMS contract could redefine how plant maintenance will be performed in the future."

"The hydrocarbon processing industry in Saudi Arabia and the region will closely observe the results of such atypical maintenance outsourcing strategy," Al-Ogaili added.

The joint venture will also provide detailed planning and scheduling services, execution of preventive and predictive maintenance programs, management of sub-contractor activities and procurement of tools and equipments.

In addition, the JV will also provide development services and reliability and cost optimization programs.

Production at the refinery is expected to begin in 2013.
