What is the significance of Delfin Midstream's final investment decision for Delfin FLNG 1?

Delfin Midstream's final investment decision for Delfin FLNG 1 marks the approval of the first floating liquefied natural gas (FLNG) vessel in the United States and the largest FLNG project globally, with an expected export capacity of 4.4 million tonnes of LNG per year. The project is under development offshore Louisiana in the Gulf of Mexico and is backed by long-term LNG sales agreements with global energy companies including Vitol, Expand Energy, Centrica, and Gunvor.

What caused the delay in Delfin LNG's financial approval, and how was it resolved?

The Delfin LNG development was delayed for months following an explosion on a pipeline near Holly Beach and Johnson Bayou in Louisiana — a pipeline expected to supply gas to the facility. According to Eduard Ruijs, head of investment at Vitol (a stakeholder in the project), the development would have secured financial approval earlier if not for that pipeline blast. The delay was ultimately overcome, leading to the positive final investment decision announced by Delfin Midstream.
