Project details

• Operator: Shell Midstream Partners LP
• Owner: Shell Midstream Partners LP
• Parent company: Shell Midstream Partners LP
• Capacity: 360,000 barrels per day (bpd)
• Length: 350 miles
• Diameter: 24 inches, 22 inches, 20 inches
• Status: Operating
• Start year: 2013

Background

The pipeline originally ran from Houma, Louisiana to Houston, Texas, and was known as the Houma-to-Houston (Ho-Ho) pipeline. In 2013 parent company Shell plc reversed the pipeline, naming it the Houston-Houma (Ho-Ho) Oil Pipeline, to supply U.S. Gulf Coast refineries with crude from oil plays in the Eagle Ford, Bakken, Permian Basin and other shale regions. From Houma, the Ho-Ho pipeline branched into two segments.

One segment carries oil to a refinery in St. James Parish, replacing and increasing the capacity of the prior Houma-St. James line. A second segment carries oil to the Clovelly oil storage facility near Galliano, which connects to the Louisiana Offshore Oil Port, or LOOP, an international oil terminal. A third segment was added as an expansion project, running from Port Neches to Houma, Louisiana.

As of May 2021, 7.5% of ownership interest in the Zydeco Pipeline was transferred from Shell Pipeline Company LP to Shell Midstream Partners, L.P, which now holds 100% ownership interest in the Zydeco Oil Pipeline.

In November 2022, the pipeline began operating at reduced capacity due to project work at Port Neches, and was expected to remain at reduced capacity until mid- to late December 2022.

Expansion projects

St. James Expansion Project

There is a proposed 40 mile expansion from Houma to St. James, Louisiana, this expansion was first proposed in 2015 by Shell plc. The project will replace a segment of the existing Zydeco Houma-St. James line that is currently operating with a capacity of 270,000 barrels per day. This expansion project would add 40 miles of new pipeline to the existing 48 miles, and the diameter would increase from its current 18-inches to 24-inches.

There is a proposed 40 mile expansion planned from Houma to St. James, Louisiana.

There have been no updates on the progress of this expansion project since 2019, however the pre-expansion segment from Houma to St. James, Louisiana is still in operation.

Houma-to-Clovelly Expansion Project

The expansion increased the transport capacity from Houma, Louisiana, to Clovelly, Louisiana, from 400,000 barrels per day to 500,000 barrels per day.

The expansion runs from Houma, Louisiana, to Clovelly, Louisiana.
