Location
Commonwealth LNG is developing a 9.5 Mtpa liquefaction and export facility on the west bank of the Calcasieu Ship Channel at the mouth of the Gulf of Mexico near Cameron, Louisiana. The facility will have five 50,000 M3 storage tanks and will be able to accommodate vessels up to 216,000 M3. Gas supply is via construction of a 3.0-mile pipeline interconnected to two major pipeline systems with significant excess transportation capacity.
Our Approach
Commonwealth’s engineering-focused approach features a highly modularized methodology, designed to streamline schedule and reduce capital costs.
The advantages of the modular approach are especially important in Southwest Louisiana. The area is the epicenter of U.S. LNG production, so the competition for construction labor and other required resources can be challenging.
Through modularization, Commonwealth can move more than 10 million workhours out of the field and into fabrication shops. This reduces field construction of the Commonwealth project to an average of less than 800 full time equivalent workers per month and less than 2,000 personnel during the peak of construction.
A typical field-built project of similar size would require a peak labor force of 8,000 to 10,000. Reducing the onsite labor force also reduces the strain on the local community’s need for additional police force, temporary infrastructure, and support.
Schedule
FID is targeted for H1’25. Using a highly modularized approach will enable the company to build the facility with greater schedule and cost assurance, allowing LNG production to begin by the end of 2028.
