As part of the deal, CB&I will involve in the engineering, procurement and construction of crude oil storage tanks at a grassroots refinery, which is being constructed by Petrofac in Saudi Arabia.

CB&I Fabrication Services operating group president Luke Scorsone said the company has provided tank and plate structure engineering, procurement, fabrication and construction services for projects in Saudi Arabia since the 1930s.

"Today, we operate a world-class fabrication facility, equipment yard and project office in Saudi Arabia," Scorsone added.
