Delfin Midstream has announced an extension of its letter of award (LoA) with Samsung Heavy Industries (SHI), marking a step forward in completing the first floating liquefied natural gas (FLNG) vessel for the Delfin LNG project off the coast of Louisiana, US.
Delfin LNG is a brownfield deep-water port project that requires minimal additional infrastructure investment to accommodate up to three FLNG vessels.

The potential output of the project is up to 13.2 million tonnes per annum (mtpa) of liquefied natural gas (LNG).
The extension of the LoA is seen as a pivotal step toward the final investment decision (FID), which is expected to be made next month.
The original LoA with SHI was established in October 2025, designating the latter as the exclusive contractor for the first vessel.
SHI has been appointed as the sole engineering, procurement, construction and installation contractor for the vessel.

By GlobalDataThe LoA also granted Delfin Midstream exclusive rights to construct the vessel at SHI’s dock.
Separately, Delfin Midstream has executed a purchase order with Siemens Energy via Black & Veatch, with whom it has formalised a concurrent LoA.
This follows an agreement reached in July 2025 that reserved manufacturing capacity from Siemens Energy for the SGT-750 Gas Turbine Mechanical Drive Packages.
Delfin Midstream had previously issued a limited notice to proceed during the autumn of 2025 to commence initial execution work on these packages.
Under the new arrangement, Black & Veatch will serve as the primary subcontractor to SHI, undertaking responsibilities for topsides engineering, procurement, and pre-commissioning and commissioning services.
To further secure the project’s timeline and execution schedule, Delfin Midstream has allocated additional equipment and reserved crucial manufacturing slots related to both the hull and topsides components.
The project will implement Black & Veatch’s patented PRICO liquefaction technology, known for its utility in various LNG applications including onshore, nearshore and floating scenarios.
Delfin Midstream CEO Dudley Poston said: “With the last parts of the project coming together, we are very pleased to plan for the FID and immediate execution by ordering and reserving key equipment. Our project represents a significant milestone in the development of critical energy infrastructure in the US.
“We are excited by our progress and our continued collaboration with SHI, Black & Veatch, Siemens Energy and key vendors as we finalise the necessary commercial and financing workstreams to bring the country’s first offshore LNG project to market.”
In March 2025, Delfin Midstream and SEFE Securing Energy for Europe entered into a heads of agreement for the long-term supply of 1.5mtpa of LNG for a minimum of 15 years.
