Delfin Midstream has signed a deal with Siemens and entered an early works programme with SHI and Black & Veatch for its Louisiana-based LNG export project
US-headquartered Delfin Midstream is working with multiple companies on progressing its Port Delfin LNG offshore LNG export terminal some 40 nautical miles from the coast of Louisiana.
The company intends for the project to be built around a trio of FLNG Vessels, each vessel capable of producing 4 million tonnes per annum (mta) of LNG and each connected to existing offshore pipelines, that transport natural gas from the US pipeline grid to the FLNG vessels.
The company successfully conducted all permitting work under the Deepwater Port Act, governed by the Maritime Administration (MARAD), received the Deepwater Port License from MARAD and received the non-FTA export license from the Department of Energy for 13.2 million tons of LNG per annum covering all three FLNG Vessels.
Contracts, early works and progress towards FID
Delfin Midstream has entered into an agreement with Siemens Energy to reserve manufacturing capacity for four SGT-750 gas turbine mechanical drive packages.
The Siemens Energy SGT-750 systems will be used to drive the mixed-refrigerant compressors for Delfin’s LNG liquefaction system. Siemens Energy Executive Board Member Karim Amin said its gas turbine mechanical drive packages are modular in design, with a high power-to-weight ratio.
At the same time, Delfin also announced that it has agreed to an early works program with Samsung Heavy Industries (SHI) and Black & Veatch (B&V) to refine FLNG vessel design specifications in preparation for an Engineering, Procurement, Construction, and Integration (EPCI) contract as the basis for contractors to execute the project in the near-term.
“This work will de-risk project execution and ensure both contractors are prepared for immediate project execution following a positive FID,” Delfin Midstream said in a statement to investors.
Delfin CEO Dudley Poston said all workstreams are on schedule and the project is currently on track for FID.
“By making this large investment to lock-in critical manufacturing capacity, we have secured our execution schedule with the anticipated delivery of our first FLNG Vessel from Samsung Heavy Industries shipyard in 2029,” he said.
“The company’s activities are in support of a Final Investment Decision (FID) anticipated in [Q3] 2025 for its leading US energy infrastructure project under development in Louisiana and offshore in the Gulf,” Delfin Midstream said.
The company’s subsidiary Delfin LNG received the first deepwater port license from the Maritime Administration (MARAD) in March 2025, authorising Delfin LNG to build, operate and own an offshore LNG export plant in the US.
“Delfin’s brownfield deepwater port requires minimal additional infrastructure investment to support up to three floating LNG vessels producing up to 13.2 million tonnes of LNG annually. The Delfin floating LNG project has the potential to not only be the first LNG export deepwater port facility in the United States, but a significant economic contributor and job creator over the long-term,” Delfin Midstream said.
The company cited its progress in developing the Port Delfin LNG project and said it is actively pursuing additional deepwater port projects in the US Gulf of Mexico (Gulf of America).
