Argent LNG selects Chart’s liquefaction tech

Argent LNG has selected LNG equipment maker Chart Industries to supply its mid-scale modular liquefaction solution for the planned LNG export terminal in Port Fourchon, Louisiana.

US-based Chart said in a statement this move represents a “significant departure” from conventional large-scale LNG facilities, challenging the industry’s traditional operational paradigm.

Chart will supply its IPSMR (integrated pre-cooled single mixed refrigerant) process technology, brazed aluminum heat exchangers, cold boxes, and air coolers to the project with a capacity of up to 20 mtpa.

Also, the company said it has begun engineering work related to the project and anticipates booking an IPSMR technology and equipment order in 2025.

Worley deal

Argent LNG said in a separate statement it has selected Australian engineering firm Worley as a partner to move its project forward.

The initial focus is on developing the site layouts and selecting the most appropriate technology to deliver the optimal outcome for capital cost, and operating efficiency and carbon intensity.

Worley will initiate the Federal Energy Regulatory Commission (FERC) process with Argent LNG and move into the pre-FEED phase where greater definition of the development will be achieved, it said.

Worley’s services will be delivered through its Houston and Baton Rouge offices while leveraging global LNG subject matter expertise.

Other contractors and suppliers will be engaged as the development matures, Argent LNG said.


These announcements follow Argent LNG’s long-term lease agreement with the Greater Lafourche Port Commission, securing 144 acres of land at Port Fourchon.

This strategic agreement paves the way for the development of Argent LNG’s export facility with a projected capacity of up to 20 mtpa pending a waterway suitability assessment and overall Federal approval, Argent LNG said on Tuesday.

According to Argent LNG’s website, the initial phase of the project would have a capacity of 10 mtpa and this would be then further increased to 20 mtpa.

The facility is designed with Worley as program managers and also Kiewit as the EPC contractor.

Additionally, the project includes a smaller-scale liquefaction plant tailored to supply LNG for LNG-powered offshore supply vessels (OSVs) in the Gulf of Mexico, according to Argent LNG.

The company said it expects to start commercial operations of the first phase in 2029/2030.
