Delfin Midstream has issued a limited notice to proceed (LNTP) to Siemens Energy for the purchase of several major components for its second floating liquefied natural gas (FLNG) production vessel, known as FLNG2.
The order covers four SGT-750 gas turbines and mixed-refrigerant compressors for the vessel, which will be located off the coast of Louisiana, US.

The issuance of the LNTP is an important step prior to the final investment decision (FID), which Delfin aims to reach by the end of 2026.
At the same time, Delfin and MidOcean Energy, a liquefied natural gas (LNG) company established and managed by EIG, have entered into an agreement under which the latter may acquire up to a 50% stake in the FLNG2 project.
This arrangement would also provide MidOcean with a corresponding portion of LNG production, subject to a positive FID and meeting standard conditions.
The FLNG2 facility is set to replicate the design of Delfin’s first FLNG vessel, FLNG1, which reached an FID in June 2026 and is now in the execution phase.
The repeat-design approach is intended to improve cost predictability and accelerate delivery schedules.
FLNG2 will have an expected nameplate capacity of 4.4 million tonnes per annum (mtpa).
Plans call for FLNG2 to be moored in the Gulf of Mexico, connecting to existing offshore pipelines via the Delfin Deepwater Port.
Delfin CEO Dudley Poston said: “This milestone underscores the commercial readiness of our floating LNG platform and is another significant step towards global energy security rapidly following a positive FID for Delfin’s FLNG1.
“Securing manufacturing slots for critical long lead equipment with Siemens Energy is an important advancement in de-risking the project schedule as we work toward FID for the second vessel.
“We are pleased to partner with MidOcean, whose deep LNG expertise and financial capabilities make them an ideal partner for FLNG2 and beyond.”
Delfin and MidOcean are also exploring the potential for a third FLNG vessel following FLNG2, underlining their interest in increasing LNG supply from the Gulf Coast.
MidOcean CEO De la Rey Venter said: “MidOcean’s potential participation in FLNG2 is consistent with our strategy to build a diversified, cost-competitive global LNG portfolio. The project’s repeat-design approach offers an attractive risk-return profile and meaningful execution advantages for all project stakeholders.
“We look forward to continue working with Delfin towards a final FLNG2 investment decision and to exploring further growth opportunities together, including the acceleration of FLNG3.”
