Port Fourchon is Louisiana’s southernmost port, located on the southern tip of Lafourche Parish, Louisiana, on the Gulf of Mexico. It is a sea port, with significant petroleum industry traffic from offshore Gulf oil platforms and drilling rigs as well as the Louisiana Offshore Oil Port pipeline. Fourchon's primary service markets are domestic deepwater oil and gas exploration, drilling, and production in the Gulf of Mexico. Port Fourchon currently services over 90% of the Gulf of Mexico's deepwater oil production. There are over 600 oil platforms within a 40-mile radius of Port Fourchon. This area furnishes 16 to 18 percent of the US oil supply.
Port Fourchon was developed as a multi-use facility. It has historically been a land base for offshore oil support services as well as a land base for the Louisiana Offshore Oil Port (LOOP). In addition, it has served as a commercial and recreational fishing mecca, foreign cargo shipping terminal, and a unique area for recreation and tourism.
The Board of Commissioners of the Greater Lafourche Port Commission is charged with ensuring the progress and continued development of Port Fourchon and the South Lafourche Leonard Miller, Jr. Airport. Nine members seated at-large comprise the Commission in lettered seats A through I. Every six years, the people of the Tenth Ward of Lafourche Parish elect all nine commissioners.
The Greater Lafourche Port Commission, established by the state of Louisiana in 1960 as a political subdivision of the state of Louisiana, exercises jurisdiction over the Tenth Ward of Lafourche Parish south of the Intracoastal Waterway, including the seaport and the airport. The Port Commission facilitates the economic growth of the communities in which it operates by maximizing the flow of trade and commerce, largely through Port Fourchon.
