Garden Banks Gas Pipeline is an offshore natural gas pipeline in the Gulf of Mexico.

Location

The pipeline runs entirely within the Gulf of Mexico. It runs from the Cardamom oil and gas field to the Titan Mini-Basin just south of Cameron, LA, where it connects to 4 existing interstate pipelines to move gas onshore.

Background

Garden Banks pipeline is one of six offshore natural gas pipeline corridors off the coast of Louisiana and Mississippi in the Gulf of Mexico. The Enbridge Offshore Pipelines 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. The Garden Banks pipeline extends from Garden Banks Block 128 to South Marsh Island Block 76, where it interconnects with 4 existing interstate pipelines to move gas onshore. Transports production originating from the Auger platform in Garden Banks Block 426, the Enchilada platform in Garden Banks Block 128, the Baldpate platform in Garden Banks Block 260, the platform in South Marsh Island (SMI192) and the Magnolia Platform in Garden Banks 783. The Garden Banks pipeline transports natural gas from the Cardamom oil and gas field in the Gulf of Mexico, which is drilled using the Auger tension leg platform (TLP) owned by Royal Dutch Shell.

Enbridge Offshore Gas Transmission LLC acquired Garden Banks Gas Pipeline from an affiliate of Amerada Hess Corporation in March 2005.

In August 2020, Enbridge declared force majeure on the Garden Banks, following Hurricane Laura.
