Louisiana LNG and Beyond: Tracking the Gulf’s LNG Pipeline
New terminals and expansions will create jobs, strengthen U.S. export leadership, and deliver global energy security from Louisiana’s LNG corridor.
The next 3–5 years will be a pivotal period for LNG development along the U.S. Gulf coast with Louisiana, and adjacent Mississippi, hosting a wave of new liquefaction terminals and export expansions. Major LNG projects in Louisiana and Mississippi are advancing through permitting, engineering and construction phases. These developments will extend U.S. export capacity and anchor regional industrial ecosystems.
Commonwealth and Cameron LNG
Among the headline projects is Commonwealth LNG, a 9.5 Mtpa export terminal on the west bank of the Calcasieu Ship Channel in Cameron Parish, Louisiana.
Commonwealth LNG has secured FERC’s final approval and is targeting a final investment decision later in 2025, with first production slated for 2029. Commonwealth is pursuing an engineering-modular approach intended to reduce field labor exposure and compress schedule risk.
Meanwhile, the Cameron LNG expansion phase is under active development. The additional train(s) will expand an already mature export hub along the Calcasieu channel, reinforcing local supply, pipeline interconnectivity, and fabrication demand. The expansion dovetails with broader Gulf-coast export capacity growth.
Monkey Island LNG
Another emerging opportunity is Monkey Island LNG, a multi-phase liquefaction project in Cameron Parish. The developer has contracted McDermott under a Master Services Agreement to lead front-end engineering and execution planning, with engineering and permitting set to begin in 2026.
The project envisions up to five liquefaction trains (each ~5 Mtpa), with later expansion to ~26 Mtpa. Monkey Island has selected ConocoPhillips’ optimized cascade technology for its liquefaction process. The first production is targeted for the early 2030s.
Baja LNG (Mexico)
Baja LNG (in Mexico, leveraging Gulf-source gas) remains another relevant reference point for cross-border export ambition, offering a potential complement to U.S. Gulf terminals by accessing Pacific markets with shorter shipping distances. While not U.S.-based, its development remains relevant to Gulf export dynamics and trade flows.
These new and expanding facilities will carry substantial regional and national impact.
Locally, they will spur demand for marine services, heavy fabrication, modular construction yards, pipeline hookups, and skilled workforce deployment across coastal Louisiana and Mississippi.
On a macro level, these projects strengthen the U.S. role as a flexible global LNG supplier, increase resilience in gas supply chains, and influence competitive dynamics in global gas pricing.
“OGCS is excited to bring proven experience to these new and developing initiatives,” says Ed Comiskey, Executive Vice President, OGCS Americas. “Our expertise and long-term commitment to Louisiana LNG shows how OGCS is delivering real value in real time.”
“Our team is ready to support clients through commissioning, contractor coordination and the critical early-operations phase, with specialist manpower and services for every stage.”
“From workforce mobilization to commercial services on complex EPC scopes, OGCS will help owners and contractors convert plans into delivered capacity, safely and efficiently,” he adds.
