Seaway Oil Pipeline
|This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.|
The Seaway Crude Pipeline System (SCPS), commonly known as the Seaway Pipeline, is an oil pipeline in the United States. It consists of both the 400,000 barrel per day (bpd) Seaway Pipeline and a 450,000 bpd parallel pipeline, Seaway Twin Pipeline.
The pipeline system runs from Cushing, Oklahoma to Jones Creek, Texas, and then east to the ECHO Terminal near Houston and terminating in Beaumont/Port Arthur, Texas.
- Operator: Enterprise Products Partners (50%), Enbridge (50%)
- Current capacity: 850,000 barrels per day
- Proposed capacity:
- Length: 805 kilometers (500 miles)
- Status: Operating
- Start Year: 1976
The Seaway system includes 500-mile, 30-inch diameter pipelines between Cushing, Oklahoma and the Freeport, Texas area, and a terminal and distribution network in Texas City, Texas, that serves refineries in the Greater Houston area. It consists of both the 400,000 barrel per day (bpd) Seaway Pipeline and a 450,000 bpd parallel pipeline, Seaway Twin Pipeline.
The Seaway system is currently adding drag reducing agents to boost capacity on the Seaway 2 Pipeline.
Seaway Crude Pipeline Company LLC (Seaway) is a 50/50 joint venture between Enterprise Products Partners L.P., the operator, and Enbridge Inc., which purchased its ownership interest from ConocoPhillips on November 16, 2011.
The Seaway Pipeline was originally built by a consortium of oil industry firms (Phillips Petroleum Company, among others) formed in 1974 named Seaway Pipeline, Inc. for transferring (then) cheap foreign oil from Texas ports to refineries in the midwest. After two years of construction, the system became operational on 23 November 1976, and pumped crude oil north until 1982, when it became inactive at times as the economics of crude transfer changed.
In 1984, the other consortium members were bought out by Phillips. Seeking to capitalize on the line's location to gather raw natural gas in Oklahoma and Texas for transport to the company's refinery complex at Sweeny, Texas, (and other refineries near Houston) Phillips converted the system to ship natural gas south instead of shipping crude oil north (Phillips called that arrangement the "Seagas Pipeline").
In 1995, Atlantic Richfield bought a 50% interest from Conoco through a subsidiary (ARCO Pipeline), and the system was converted from shipping natural gas south to shipping oil north to Cushing in 1996.
In 2000, Texas Eastern Products Pipeline Company (TEPP or TEPPCO), an indirect subsidiary of Duke Energy through TEPPCO Partners, bought the stock of ARCO Pipeline, acquiring their 50% interest in the system, and became primary operator.
In late 2011, Canadian pipeline company Enbridge bought Conoco's remaining 50% interest in the company for $1.15 billion. The Seaway Crude Pipeline Company LLC (joint venture between Enterprise Products and Enbridge) became the pipeline's operator.
After the reversal the pipeline's capacity increased from 150,000 to 400,000 barrels per day (bpd).
A new pipeline, which parallels the existing Seaway pipeline, more than doubled its capacity to 850,000 bpd following completion in July, 2014. It is known as the Seaway Twin pipeline.
The Seaway reversal and expansion projects have given shippers access to Enterprise's ECHO crude oil storage facility in southeast Houston and the Port Arthur/Beaumont refining complex.
On January 30, 2017, a road crew punctured the Seaway pipeline. Two days later, it was unclear how much oil had spilled, although 4,000 barrels of oil (168,000 gallons) had been recovered, according to Texas Railroad Commission. After the incident, supply concerns reportedly helped push "oil prices 2% higher in early trading to nearly $54 a barrel."
