Delfin's $5bn FLNG FID Puts US Offshore Export Model to the Test
First US floating LNG terminal clears final investment decision as domestic gas output expands and five new projects target 2027 ramp-up.
Delfin Midstream announced on Wednesday (2026-06-03) a $5 billion final investment decision to build the United States' first floating LNG facility off the Louisiana coast. The project, approved last year by the Trump administration, will be the largest FLNG development globally.3,2
The decision tests whether deepwater floating liquefaction can break the permitting and construction bottlenecks that have constrained US export capacity additions. The US currently operates nine large-scale LNG terminals with roughly 15.4 Bcf/d of liquefaction capacity.4,2
Delfin FLNG 1 is the anchor of a broader buildout. The company plans to pair this near-term floating project, targeted for 2027 operations, with a larger 12-30 mtpa land-and-sea export complex. That staged approach spreads capital across two very different regulatory and construction timelines.3
The FID arrives as US gas supply fundamentals tighten. EIA data show L48 marketed production averaged 117.2 Bcf/d in the first quarter of 2026, up 4% year-on-year. The agency forecasts full-year output to rise another 3%, driven mainly by the Permian, expected to produce 29.2 Bcf/d this year, a 6% gain.1
Constraint relief later this year should unlock Permian growth of 10% in 2027, according to EIA projections. The Haynesville, the gas-dominant region most directly tied to Gulf Coast LNG feedgas demand, is forecast to grow 6% this year and 8% next.1
Those supply gains map directly onto the export ramp. EIA's April STEO projected US LNG exports would grow nearly 30% by the end of 2027 as five projects start operations and ramp. Delfin is now one of those five, giving buyers a firm 2027 start date rather than another speculative announcement.5
The floating design carries distinct advantages. Delfin's hull-mounted liquefaction avoids the land-based permitting fights that have delayed rival projects in Texas and Louisiana. But it also carries execution risk — no US operator has built an FLNG facility before, and the technology's track record is concentrated in smaller Australian and Malaysian projects.2
The US export picture is not purely one-directional. Last year's disruption in global supply pushed US LNG to supply 93% of worldwide export growth in 2025, according to Forbes, and that dominance exposes domestic prices to overseas weather events and geopolitical shocks.6
For Delfin's backers, the 2027 timeline is the selling point. Spot JKM for Asian LNG printed $21.24/MMBtu on the August 13 screen, keeping Atlantic arbitrage economics competitive with NYMEX Henry Hub front-month gas at $2.78/MMBtu.6 [LIVE_PRICES]
But those same economics cut the other way. The 2025 US supply surge that underpinned the export boom also compressed domestic prices, and the EIA expects storage withdrawals and winter demand to tighten the balance through the coming season. Delfin's feedgas will be competing with every other Gulf Coast terminal for the same Permian and Haynesville molecules.1,6
Watch the project's financing documentation for a firm 2027 commissioning date. Delfin remains a single-project entity, and the $5 billion FID is the first test of whether institutional lenders will back US floating LNG at scale. If the facility hits its schedule, expect the remaining 12-30 mtpa expansion to move quickly. If it slips, the technology has no US track record to fall back on.3,2
