Louisiana Offshore Oil Port (LOOP), the nation’s only deepwater port, is located eighteen miles southeast of Port Fourchon and uses the port as its land base. Constructed by a group of major oil and pipeline companies in 110 feet of water, LOOP serves as the central unloading and distribution point for all incoming supertankers to the Gulf region.

Large supertankers continuously offload millions of barrels of crude oil into the LOOP pipeline. The oil then travels north to the Galliano Salt Dome in Lafourche Parish, where it is stored and piped to 50% of this nation's refining capacity. LOOP handles approximately 10% of the country's imported oil and about 10% of the nation's domestic oil.
