Cameron Highway Oil Pipeline System (CHOPS)

This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.

Cameron Highway Oil Pipeline System (CHOPS) is a deepwater crude oil pipeline system that transports production in the Gulf of Mexico to refineries in Texas, USA.[1] It is the longest offshore oil pipeline in the United States.[2]


The pipeline originates in the Gulf Coast waters (off Texas and Louisiana) and terminates in Texas City, Texas.

More specifically, the system originates at the Ship Shoal 332 A/B Hub as a 30-inch diameter pipeline, traverses the GB 72 platform, and divides into two, 24-inch diameter pipelines at the High Island A5-C platform.[1] The two 24-inch pipeline segments terminate in Texas City, Texas, and Port Arthur, Texas, respectively.[1]

As of November 2021, Genesis Energy LP owned 100% interest in the Cameron High Oil Pipeline Company, though it then sold 36% to an undisclosed financial party for about US$418 million.[4]


The Cameron Highway oil pipeline system consists of a 380-mile, 24-inch and 30-inch diameter oil pipeline that extends along the Outer Continental Shelf of the Gulf of Mexico and delivers crude oil from major deepwater oil fields to markets on the Texas Gulf Coast.[1] It was first announced in 2002.

As of 2017, it had "dedications from the Holstein, Mad Dog, Atlantis, K2, Constitution and Ticonderoga fields, all of which are located in the deepwater Green Canyon area offshore Louisiana."[1]

In August 2017, the Cameron Highway Oil Pipeline system went offline due to Hurricane Harvey.[6]
