Overview
Delfin LNG is the commercial name associated with Delfin LNG LLC, a wholly owned subsidiary of Delfin Midstream. The company’s principal disclosed role is tied to the Port Delfin LNG Project, an offshore natural-gas export development located approximately 40 nautical miles off the coast of Louisiana. Delfin Midstream describes itself as a North American developer of LNG export projects using floating LNG technology. The Port Delfin project is planned around three floating LNG (FLNG) vessels. Each vessel is designed for capacity of 4 million tonnes of LNG per year and is to connect to existing offshore pipelines carrying natural gas from the US pipeline grid. The project’s development materials also describe a licensing basis covering exports of 13.2 million tons of LNG per annum for all three vessels. These are project plans and authorized export capacity, not evidence that the facility is operating or producing LNG. Delfin LNG LLC owns the UTOS pipeline, which runs from Station 44 to the WC-167 platform. Delfin Midstream also reports a long-term lease for the HIOS pipeline from WC-167 south to the planned deepwater port location. The company presents access to existing offshore pipeline infrastructure as part of the project’s development approach. The parent company says it completed permitting work under the Deepwater Port Act, received a Deepwater Port License from the US Maritime Administration (MARAD), and obtained a non-FTA export license from the Department of Energy. Delfin Midstream is also pursuing additional deepwater-port projects in the Gulf of America. The supplied company information lists offices in Pensacola, Florida, and Oslo, Norway, but does not identify a corporate headquarters, founding date, or founder.
History
Delfin LNG LLC is presented in the supplied company material as a wholly owned subsidiary of Delfin Midstream. The available sources do not state when Delfin LNG LLC was founded, identify its founder, or provide a dated account of the company’s formation. Its documented history is therefore best described through the development of the Port Delfin LNG project and the associated pipeline and permitting work. Delfin Midstream describes its broader business as developing North American LNG export projects with floating LNG technology. The parent company says its team has experience developing, constructing, and operating floating LNG assets, including LNG carriers, floating LNG import terminals, and floating LNG export terminals. The central project associated with Delfin LNG is Port Delfin, an offshore LNG export terminal planned approximately 40 nautical miles from Louisiana’s coast. The project concept comprises three FLNG vessels, each designed to produce 4 million tonnes of LNG per year. The vessels are intended to connect to existing offshore pipelines that transport natural gas from the US pipeline grid. Delfin LNG LLC owns the UTOS pipeline between Station 44 and the WC-167 platform. Delfin Midstream reports a long-term lease for the HIOS pipeline running south from WC-167 toward the planned deepwater-port location. The parent company has described the UTOS line as a 42-inch pipeline and said it was formerly owned and operated by Enbridge. Delfin Midstream reports that it completed permitting work under the Deepwater Port Act, received a Deepwater Port License from MARAD, and obtained a US Department of Energy non-FTA export license covering 13.2 million tons of LNG per annum for all three FLNG vessels. The supplied information does not give dates for these permitting milestones. It also does not establish that the planned terminal has reached a final investment decision, been constructed, or begun commercial operations. The parent company describes further growth opportunities, including additional deepwater-port development in the Gulf of America and expansion potential involving the Avocet LNG project and a Texas DWP project. It also describes commercial and financial structures for the individual FLNG vessels and participation opportunities for LNG buyers, strategic investors, and other value-chain stakeholders. These are presented as development and expansion opportunities rather than as proof of completed projects. Company contact information lists offices in Pensacola, Florida, and Oslo, Norway. The materials do not specify a headquarters or provide founding, ownership-transfer, listing, or executive appointment dates for Delfin LNG LLC.
