CB&I Baton Rouge is one of the most strategically important facilities in North American tank and terminal construction — a hub for engineering, fabrication services, and major LNG project execution that has delivered some of the largest storage structures on the Gulf Coast. Located on Industriplex Boulevard in Baton Rouge, Louisiana, the operation sits within reach of the region’s most active LNG, refining, and petrochemical project corridors.
CB&I Baton Rouge: Facility Overview
CB&I has maintained a significant Baton Rouge presence for decades, with its Louisiana operations registered under CB&I Storage Tank Solutions LLC and CB&I Group Inc. The Industriplex Boulevard address serves as the base for engineering and fabrication services teams supporting projects across the Gulf of Mexico region. At its peak, the Baton Rouge operation employed between 1,000 and 4,999 workers according to commercial registry data, reflecting the scale of project activity passing through the Louisiana office.
The facility sits within Baton Rouge’s Industriplex industrial corridor — a concentrated zone of energy-sector operations southwest of the city centre that provides direct logistics access to the Gulf Coast project pipeline. CB&I’s presence here positions it close to the refining and petrochemical clusters of the Mississippi River corridor, as well as the LNG export infrastructure building out along the Louisiana coastline.
Tank Fabrication Capabilities
CB&I is the world’s leading designer and builder of storage facilities, tanks and terminals, with more than 60,000 structures completed across a 130-year operating history. Its fabrication capability spans ambient and cryogenic storage, full containment LNG tanks, crude and product terminals, petrochemical storage, and water storage infrastructure. The Louisiana operations feed directly into this global execution model, with the Gulf Coast region representing one of CB&I’s highest-density project markets worldwide.
A defining technical capability associated with CB&I Baton Rouge is air-raise roof installation — a method used on large-volume LNG and petroleum storage tanks where the completed roof assembly is lifted into position using low-pressure compressed air rather than cranes. CB&I has completed more than 1,000 air raises since 1962, a figure that reflects both the longevity of the technique and the scale at which it has been deployed on projects across Louisiana and beyond.
Venture Global Calcasieu Pass: A Flagship Louisiana Project
The most significant recent deployment of CB&I Baton Rouge’s LNG fabrication capability was the construction of dual 200,000 m³ full containment LNG storage tanks at Venture Global’s Calcasieu Pass export facility in Cameron Parish, Louisiana. CB&I Storage Tank Solutions — operating at the time as a division of McDermott International — won a contract valued at approximately $200 million for the tank scope, one of the largest single tank construction awards on the US Gulf Coast.
Both tank roofs were air raised in spring 2020. The first, a 1.8 million pound dome assembly, was raised on 24 April 2020 in under two hours using 0.25 psi of pressure — completing ahead of schedule just eight months after the project’s final investment decision. The second roof was raised on 19 May 2020, nearly three months ahead of the original programme. The Calcasieu Pass facility — now operational at 10 MTPA capacity — stands as one of the most cited examples of CB&I’s full containment LNG tank construction capability on the Gulf Coast.
CB&I subsequently secured the tank construction contract for Venture Global’s Plaquemines LNG project, covering the first two storage tanks in Phase 1 and two further tanks in Phase 2. The Louisiana project pipeline has made CB&I a critical infrastructure partner for one of the US’s most active LNG developers.
CB&I Baton Rouge in Context: Ownership and Structure
The CB&I operating entity in Baton Rouge sits within the broader CB&I corporate structure, which was separated from McDermott International following the latter’s 2020 Chapter 11 restructuring. CB&I is now owned by a consortium of financial investors led by Mason Capital Management LLC, operating as a focused storage and asset solutions business with two global units: Storage Solutions (tanks, terminals, storage systems) and Asset Solutions (operations, management, wells and decommissioning).
The separation from McDermott restored CB&I’s identity as a dedicated tank and terminal contractor — the business it built across more than a century before the 2018 McDermott merger diluted that focus. For the Baton Rouge operation, this means continued alignment with Gulf Coast LNG, refining, and petrochemical terminal projects rather than the broader offshore and process plant EPC work that characterised the McDermott era.
CB&I’s wider global tank and terminal profile covers operations across every major energy region, with the Baton Rouge facility forming part of a strategically distributed North American construction network. For operators and developers assessing North America’s leading tank terminal EPC contractors, CB&I’s Louisiana presence and its LNG full containment track record remain central to its competitive positioning.

Where is CB&I’s Baton Rouge facility located?
CB&I’s Baton Rouge operation is located on Industriplex Boulevard, Baton Rouge, Louisiana 70809. The Louisiana entity — CB&I Storage Tank Solutions LLC — has been registered in the state since 1983 and serves as a base for engineering and fabrication services across the Gulf Coast project region.
What does CB&I do in Baton Rouge?
The Baton Rouge facility supports CB&I’s tank fabrication, engineering, and Gulf Coast project execution operations. Services include full containment LNG tank construction, API 650 petroleum storage tanks, air-raise roof installation, and EPC contracting for terminals and storage facilities across the Louisiana and Gulf of Mexico corridor.
What is CB&I’s air-raise technique and why is it used?
Air raising is a method where a completed tank roof assembly is lifted into position using low-pressure compressed air — typically around 0.25 psi — rather than cranes. The technique allows the roof to be fabricated and erected concurrently with the tank shell, compressing the construction schedule. CB&I has completed more than 1,000 air raises globally since 1962, including both LNG storage tank roofs at Venture Global’s Calcasieu Pass facility in Louisiana.
What major LNG projects has CB&I Baton Rouge worked on?
The most significant recent project was Venture Global’s Calcasieu Pass LNG export facility in Cameron Parish, Louisiana, where CB&I built dual 200,000 m³ full containment LNG storage tanks under a contract valued at approximately $200 million. Both tank roofs were air raised in April and May 2020, ahead of schedule. CB&I also holds the tank construction contract for Venture Global’s Plaquemines LNG project, covering four storage tanks across two phases.
Who owns CB&I now?
CB&I is owned by a consortium of financial investors led by Mason Capital Management LLC. The company was separated from McDermott International following McDermott’s 2020 Chapter 11 restructuring, restoring CB&I as a focused tank and terminal EPC business operating through two global units: Storage Solutions and Asset Solutions.
