CB&I Lands $250-500M Contract to Build Five LNG Storage Tanks for Commonwealth LNG in Louisiana
According to Rigzone, The Woodlands, Texas-based CB&I has won a contract to build five 50,000-cubic meter (1.77 million cubic foot) LNG storage tanks for the Commonwealth LNG project in Cameron Parish, Louisiana, with the contract valued between $250 million and $500 million.
A Major Gulf Coast LNG Project Moves into Execution
CB&I was subcontracted by Netherlands-based Technip Energies NV, which received a full notice to proceed (FNtP) from project owner Caturus HolCo LLC on May 18, 2026. CB&I’s scope covers foundation design and construction, piping to grade, and LNG tank top platforms. Work will be managed out of CB&I’s Houston-area and Plainfield, Illinois offices, with construction scheduled to begin in Q3 2026 and mechanical completion targeted for 2029.
The broader Commonwealth LNG project reached a final investment decision on May 15, 2026, backed by a $13 billion commitment from Caturus, a joint venture of Kimmeridge Energy Management Co LLC and Mubadala Investment Co. The project also secured $9.75 billion in additional financing, with total commitments reaching $21.25 billion. Long-term offtake agreements are in place with EQT, Glencore, Mercuria, PETRONAS, and Aramco Trading. The project holds federal authorization to export up to 9.5 million metric tons per year of LNG and is expected to begin operations in 2030, generating more than $3 billion in annual export revenue.
Technip’s scope includes delivery of six identical liquefaction trains using its SnapLNG modular solution. “By employing a single design replicated across all six trains, SnapLNG by T.EN offers accelerated project schedules and optimized costs, alongside improved predictability and certainty at scale,” Technip said in its FNtP announcement.
What It Means for Subcontractors
- Civil and foundation work is coming. CB&I’s scope explicitly includes foundation design and construction, meaning civil subcontractors in the Cameron Parish and Southwest Louisiana area should be positioning now ahead of a Q3 2026 construction start.
- The project timeline is firm and funded. With $21.25 billion in total commitments and a confirmed FNtP, this is not a speculative project. Subcontractors can pursue pre-qualification and bidding with confidence in project continuity.
- Piping and mechanical contractors should take note. Piping to grade is part of CB&I’s awarded scope, and with six liquefaction trains and five storage tanks in play, the downstream mechanical and piping workload at this site will be substantial through the 2029 mechanical completion target.
- Modular construction creates structured workflow. Technip’s SnapLNG approach uses a single replicated design across all six trains, which tends to favor subcontractors who can demonstrate repeatability, quality consistency, and scalability across multiple identical units.
- Get on the supplier lists early. With CB&I managing execution from its Houston-area offices, subcontractors in the Gulf Coast region should be reaching out to CB&I and Technip Energies now to establish relationships before the major procurement phases lock in preferred vendors.
