Project Overview

Delfin LNG is proposing the first offshore floating natural gas liquefaction project in the United States. The project is currently in the deepwater port license application process with the United States Coast Guard (USCG) and Maritime Administration (MARAD). Delfin expects to be operational in 2020.

The Delfin LNG Deepwater Port project has four main parts:

  • Newly built onshore gas compression on existing site (brownfield)
  • The use of existing 42-inch pipelines to transport natural gas nearly 50 miles offshore
  • The offshore port complex comprised of four moorings
  • Four floating LNG vessels (FLNGVs) with total export capacity of 13 million metric tonnes per year

Delfin initiated the purchase of the UTOS Pipeline (now Delfin Offshore Pipeline) from Enbridge Inc in 2012 and closed the transaction in 2014. The pipeline was originally built to transport gas from offshore wells in the Gulf of Mexico into the U.S. natural gas market; however, Delfin LNG will build an onshore compression facility to reverse the flow of the pipeline to deliver processed gas from onshore sources to the Delfin LNG Deepwater Port.

The Delfin LNG Deepwater Port will receive natural gas from the Delfin Offshore Pipeline and have four mooring facilities (detailed maps below) for FLNGVs. The FLNGVs moored at the port will have the capacity to liquefy and store natural gas. Periodically, the LNG will be transferred from storage tanks on the FLNGV to an LNG carrier where it will be delivered to customers around the world.

Delfin is convinced that floating liquefaction will be the future of LNG production. Floating liquefaction is environmentally friendly, cost competitive, economical with limited scale, moveable in the event of a hurricane, and has a shorter and more efficient schedule relative to an onshore plant. Further, in the event that global energy markets drastically change in the coming decades, a floating liquefaction plant provides greater flexibility for decommissioning and re-deployment. The offshore location of the Delfin LNG Deepwater Port, nearly 50 miles off the coast of Louisiana, will significantly reduce coastal LNG carrier traffic while minimizing near shore environmental impacts.
