The project was included in CB&I's backlog in the third quarter of 2016.

The scope of work includes detailed engineering, procurement services, construction management services and commissioning services of multiple process units, including a 2.5 million ton per annum hydrocracker unit licensed by Chevron Lummus Global, a joint venture between CB&I and Chevron.

CB&I previously announced awards for the technology license and FEED contract for multiple process units, as well as detailed engineering, procurement, fabrication and supply of a steam methane reformer for a large-scale hydrogen plant, hydrocracking heaters and Breech-Lock exchangers.

"CB&I is pleased to extend our relationship with NefteGazIndustriya and appreciate their confidence in our integrated capabilities," said Philip K. Asherman, CB&I's President and Chief Executive Officer. "The Afipsky refinery modernization is significant for NefteGazIndustriya and building this high-conversion unit will allow it to become one of the most modern and competitive refineries in Russia."
