Delfin Midstream and SEFE Securing Energy for Europe have signed a heads of agreement for the long-term supply of 1.5 million tonnes per annum (mtpa) of liquefied natural gas (LNG) for a minimum of 15 years.

The LNG will be sourced from Delfin-deployed floating LNG (FLNG) vessels located 40 miles offshore near Cameron, Louisiana, on the US Gulf Coast.

The free-on-board deliveries will begin immediately after the construction and commissioning of the FLNG vessels, ensuring SEFE can provide LNG supply security to its customers.

Delfin CEO Dudley Poston said: “We are very pleased to enter into this agreement with SEFE and continue to build on Delfin’s position as a leading source of reliable low-cost energy from the safety of the United States. We look forward to continuing to advance our critical energy infrastructure project for the benefit of our US stakeholders and international commercial partners.”

Delfin LNG is a brownfield deep-water port project that the developer claims will require only minimal additional infrastructure investment to accommodate FLNG vessels capable of producing up to 13.2mtpa of LNG.

In 2015, Delfin submitted its application for a deep-water port licence and subsequently received a favourable Record of Decision from the Maritime Administration. Additionally, the company obtained the Deepwater Port Licence and secured approval from the Department of Energy (DOE) for long-term LNG exports to countries without free trade agreements with the US, allowing for exports of up to 13.2mtpa.

SEFE CCO Frederic Barnaud said: “This long-term agreement with Delfin enables SEFE to further diversify its LNG portfolio with greater destination flexibility. This in turn ensures the security of supply of SEFE’s customers in Europe and around the world.”

Earlier this month, the US DOE approved an extension to Delfin LNG’s export permit, providing Delfin with more time to initiate exports from its planned offshore project in Louisiana.

Delfin, which is majority-owned by Fairwood Peninsula, Talisman Global Alternative Master and Talisman Global Capital Master, expects to take a final investment decision (FID) later this year.

It plans to commence construction of its offshore FLNG vessel following the FID.
