Delfin Midstream Inc. (Delphin) has entered into an agreement with Siemens Energy Inc. (Siemens Energy) to reserve manufacturing capacity for four SGT-750 gas turbine mechanical drive packages.
Delfin also announced that it has agreed to an early works program with Samsung Heavy Industries (SHI) and Black & Veatch Inc. (B&V) to further detail floating liquefied natural gas (FLNG) vessel design specifications as basis for the Lump Sum Turn-Key Engineering, Procurement, Construction, and Integration (EPCI) contract and to prepare both contractors for the execution of the project. Delphin’s activities are in support of a final investment decision (FID) anticipated in the Fall of 2025 for its US energy infrastructure project under development in Louisiana and offshore in the Gulf of Mexico.
The agreement with Siemens Energy reserves manufacturing capacity for four SGT-750 gas turbine mechanical drive packages which will be used to drive the mixed-refrigerant compressors for Delfin’s LNG liquefaction system. Delfin’s early works program agreement with Samsung and B&V will further detail FLNG Vessel #1 design specifications as basis for the Lump-Sum Turn-Key EPCI contract. This work will de-risk project execution and ensure both contractors are prepared for immediate project execution following a positive FID.
Dudley Poston, Delfin CEO, said, “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.”
On March 21, 2025, Delfin LNG LLC (Delfin LNG), a subsidiary of Delfin, received the first deepwater port license from the Maritime Administration (MARAD) authorizing Delfin LNG to own, construct, operate, and export liquefied natural gas (LNG) from the United States.
Delfin LNG is a brownfield Deepwater Port requiring minimal additional infrastructure investment to support up to three FLNG Vessels producing up to 13.2 MTPA of LNG. Delfin purchased the UTOS pipeline in 2014, the largest natural gas pipeline in the Gulf of Mexico. Delfin LNG received a deepwater port license from MARAD and approval from the Department of Energy for long-term exports of LNG to countries that do not have a Free Trade Agreement with the United States.
The Delfin Newbuild FLNG Vessel uses gas turbine driven technology and air-cooling for both liquefaction, process, and utility cooling duties. The FLNG design is a liquefier concept that receives pipeline quality feedgas and is therefore not producing from a reservoir like an LNG FPSO. As such the design is significantly less complex and lower in costs, according to Delfin.
