Enbridge U.S. Operations

The Enbridge Offshore Pipelines—which include the UTOS, Stingray, Garden Banks, Nautilus, Manta Ray, Mississippi Canyon and Destin systems—provide joint venture interests in 12 transmission and gathering pipelines in six major pipeline corridors in Louisiana and Mississippi offshore waters of the Gulf of Mexico. The system moves on average 3 billion cubic feet per day of natural gas—about 40 percent of all deepwater Gulf of Mexico natural gas production. EOP map.gif
