Fluor Corporation announced that the company signed contracts with Valero Energy Corporation to provide engineering, procurement, construction and construction management services for its Unified Hydrocracker (HCU) Program projects at its St. Charles, La., and Port Arthur, Texas refineries. The contracts for the HCU Program expansion projects totaling $1.2 billion were booked in the second quarter of 2008.

The two projects are part of a major growth program for Valero at their St. Charles and Port Arthur refineries. They have been designed to capitalize on the production of ultra-low sulfur diesel transportation fuels through the addition of two hydrocrackers.
