Argent LNG taps GIS Engineering for Port Fourchon LNG permitting work

Argent LNG has hired Louisiana-based GIS Engineering to handle marine, environmental and site engineering work for its proposed 25 MTPA LNG export terminal at Port Fourchon. The contract is meant to support the project’s FERC permitting process and advance Argent LNG’s Louisiana-first supply chain strategy.

Why it matters: - The contract moves Argent LNG’s proposed Port Fourchon terminal deeper into the federal permitting process. - The award also reinforces Argent LNG’s Louisiana First procurement strategy, which is designed to keep more work, expertise and spending in-state. - The project is a proposed 25 million tonne per annum LNG export terminal and one of the largest planned LNG projects in the U.S.

What happened: - Argent LNG awarded GIS Engineering, LLC a comprehensive marine, environmental and site engineering services contract. - The work supports the federal permitting process for the proposed LNG export terminal at Port Fourchon, Louisiana. - Argent LNG said the award is part of its systematic execution of its FERC permitting roadmap. - The announcement was made July 7, 2026.

The details: - The contract covers six integrated service packages: - Storm surge analysis. - Maritime traffic and navigation study. - Ship simulation study. - Marine facility basis of design and dimensional design suitable for FERC filing. - Flood wall sizing and design suitable for FERC filing. - Soil improvement and site preparation dimensional design suitable for FERC filing. - Wetland delineation studies and wetland mitigation report for FERC approval. - Argent LNG said the deliverables will be developed to FERC submission standards and folded into the company’s ongoing pre-filing application. - The work is intended to support environmental review under the National Environmental Policy Act and the project’s marine, site preparation and mitigation design. - Argent LNG has submitted 11 Resource Reports to FERC so far. - Those reports cover general project description, water use and quality, fish and wildlife, cultural resources, socioeconomics, geological resources, soils, land use, air and noise quality, alternatives and visual resources. - The company said the contract is the next phase of the technical work program needed to move toward a Draft Environmental Impact Statement and eventual project authorization. - Argentin LNG continues to advance FERC permitting, DOE export authorization, commercial offtake development and financing preparation in parallel. - The company said it remains on track toward a final investment decision and construction start. - GIS Engineering is headquartered in Galliano, Louisiana, and traces its roots to 1948 in Grand Isle. - The firm said it has nearly 3,000 employees, 21 facilities and 20 service lines. - GIS’s Coastal Design and Infrastructure Division focuses on marine facility design, coastal restoration, flood protection, wetland science and Gulf Coast infrastructure development. - More information is available in the company’s announcement.

Between the lines: - The GIS award shows Argent LNG is choosing local firms for technically specialized work, not just routine procurement. - That matters because permitting for a Gulf Coast LNG terminal depends heavily on coastal, maritime and environmental analysis. - The Louisiana First strategy is also a political and economic message, tying the project’s success to local jobs and suppliers.

What's next: - Argent LNG said it will keep reporting Louisiana First procurement milestones as the project advances. - The company’s near-term focus remains completing the technical work needed for the FERC review process. - Longer term, Argent LNG is still working through DOE authorization, commercial contracts and financing before a final investment decision and construction. - GIS Engineering will produce the engineering and environmental deliverables needed for the filing package.
