Another deep dive into offshore natural gas transportation

New deepwater projects, storage expansion potential strengthen Enbridge’s footprint on the U.S. Gulf Coast

May 06, 2025

Opportunity runs deep for Enbridge in the Gulf.

In this case, thousands of feet deep.

With 12 active natural gas gathering and Federal Energy Regulatory Commission (FERC)-regulated natural gas transmission pipelines traveling well below the water’s surface, Enbridge is the largest transporter of offshore volumes in the Gulf.

We transport about 60% of total natural gas production in the Gulf—and deliver about 1 billion cubic feet per day (Bcf/d).

“Sometimes I think people don’t realize it, (but) we are the real deal in offshore (transportation),” Enbridge President and CEO Greg Ebel recently remarked during our Enbridge Day investor community conference in New York on March 4.

Presently, he added, “you’re seeing a further revival of Gulf supply . . . and it makes a lot of sense, because of all the LNG (export) facilities that are there.”

Pipeline welding and a pipeline drill bit Enbridge’s offshore natural gas assets include the Cleopatra, Destin, Garden Banks, Manta Ray, Mississippi Canyon, Nautilus, Okeanos, Vito Gas and Walker Ridge systems, and individual laterals to the Magnolia, Neptune and Shenzi developments.

In October 2024, Enbridge announced plans to build, own and operate deepwater pipelines to support bp’s Kaskida development. A 12-inch-diameter natural gas line, known as the Canyon Gathering System, will transport up to 125 million cubic feet per day, connecting with our existing offshore network via the Magnolia gathering and Garden Banks transmission lines.

The US$700-million project also includes a 200,000 barrel-per-day oil pipeline known as the Canyon Oil Pipeline System. Both lines are expected to enter service by 2029.

Enbridge is also developing the deepwater Sparta Gas Pipeline, a 50-50 joint venture with Shell, to transport up to 30 million cubic feet per day in the Garden Banks corridor and connect with our Magnolia line. Also part of this Sparta Field development is the Sparta Oil Pipeline, another 50-50 JV between Enbridge and Shell that’s expected to transport 86,000 barrels per day; expected in-service date for both lines is 2028.

A prize Permian plan: Our Whistler assets in West Texas

As Cynthia Hansen, our Executive Vice President and President of our Gas Transmission and Midstream business, noted on Enbridge Day, these offshore activities are just one part of our growing—and formidable—presence on the Gulf Coast.

That includes our Permian egress pipeline plays, our comprehensive LNG export connectivity—and also our strategic gas storage facilities in Texas and Louisiana. Between the Tres Palacios, Moss Bluff, Egan and Bobcat facilities, we have about 105 Bcf of net working capacity on the Gulf Coast, with storage expansion potential of another 24 Bcf.

“We are connected to all the LNG export facilities on the U.S. Gulf Coast. We’re the largest offshore pipeline operator on the gas side. And we have a really large storage position,” she said.

“In fact, that storage that we have is incredibly valuable. We have 10% of all the (gas) storage in North America and 105 Bcf right on the Gulf. And that gives our customers unparalleled access to reliable energy.”
