CB&I, an engineering, procurement and construction firm, has secured a $300m contract by Williams Olefins for a petrochemicals expansion project in Geismar, US state of Louisiana.

The scope of the contract includes the license and basic engineering for the ethylene technology, the supply of the cracking furnaces, and the detailed engineering, procurement, and construction of the expansion project.

The plant capacity is expected to be increased from 1.35 to 1.95 billion pounds per year.

CB&I president and CEO Philip K. Asherman said the company is pleased to be selected for this important US ethylene project.

"The petrochemicals market is re-emerging in the US due to the abundance of lower cost ethane feedstock, directly attributable to increased shale gas production," said Asherman.

"This award reflects the industry’s confidence in CB&I’s ability to provide both proven technology and EPC services to the petrochemicals market."
