Natural Gas Pipelines

Offshore Pipeline Transportation


We own approximately 1,200 miles of offshore natural gas pipelines, primarily servicing deepwater production in the Gulf of Mexico.

The pipelines typically receive natural gas from production facilities and other pipelines through interconnects and transport the natural gas to downstream pipelines or processing facilities. An overview of the pipeline systems and our ownership interests is below.
