Williams Partners’ Mid-South natural gas pipeline expansion now in service

Williams Partners LP’s expansion of its interstate Transco pipeline into parts of the Southeast U.S. is completed and in service. the Tulsa-based natural gas transporter announced Monday.

The fuel is going to power generators in North Carolina and Alabama as well as a local distribution company in Georgia. The expansion’s added capacity provides enough natural gas for service to approximately one million homes, Williams Partners estimated in its release.

“This expansion represents another milestone in our build-out of Transco, the nation’s largest gas pipeline system and a significant platform for growth,” Rory Miller, Williams’ senior vice president of the Atlantic-Gulf unit, said in a statement. “We’re executing on more than $1.5 billion in additional Transco expansion projects primarily to create efficient access between the prolific natural gas production areas in the Northeast U.S. to growing demand centers in numerous Southeast and Atlantic Seaboard states.”

The Mid-South Expansion includes about 23 miles of new pipeline, a new compressor facility in Dallas County, Ala., and upgrades to existing compressor facilities in Alabama, Georgia, South Carolina and North Carolina.

Transco is one of three interstate pipelines owned and operated by Williams Partners. The 10,200-mile system moves natural gas from the Gulf Coast to the eastern United States. Tulsa-based Williams Cos. Inc. owns a controlling stake in Williams Partners.

Gas pipeline connections start on Transco expansion

Written By Renée Kiriluk-Hill/Hunterdon Democrat at www.nj.com

Steps have been completed as work proceeds on the Transco pipeline expansion project in Franklin and Union townships in Hunterdon County.

In this area Williams Co. has completed pre-construction surveys, cleared and graded land, trenched — moving topsoil to separate mounds in agricultural areas — strung pipe near the trench.

According to the company, once pipe sections are welded together they are “placed on temporary supports along the edge of the trench. All welds are then visually and radiographically inspected. Line pipe, normally mill-coated or yard-coated prior to stringing, requires a coating at the welded joints. Prior to the final inspection, the entire pipeline coating is electronically inspected to locate and repair any coating faults or voids” before the pipe is placed in the trench and backfilling begins.

That is followed by testing the pipeline and restoration of the work area.

The pipeline is intended to supply the New York-area market with natural gas from the Marcellus Shale, primarily in Pennsylvania

Williams Partners seeks Transco Pipeline expansion to NYC

Williams Partners LP is seeking federal approval for an $182 million expansion of its Transco Pipeline to New York City, the Tulsa-based natural gas infrastructure company announced Monday.

The Rockaway Delivery Lateral Project would move about 647,000 dekatherms of natural gas per day to National Grid’s distribution system in the Brooklyn and Queens boroughs of the city, according to reports. Construction on the pipeline expansion, once approved by the Federal Energy Regulatory Commission, would begin late this year with service expected by the second half of 2014.

“The project would create an additional delivery point from the existing Transco system into National Grid’s distribution network, enhancing service reliability and serving growth in the region,” Frank Ferazzi, general manager of the Transco system, said in a statement.

“This project is critical to providing the additional natural gas supplies New York City needs.”

The 26-inch diameter Rockaway delivery project would include 2.9 miles of offshore and 0.3 miles of onshore pipeline.

Williams would utilize subsurface directional drilling in the sea-to-shore portion of the pipeline to avoid impacts to beaches and near-shore areas.

Last month, Williams Partners announced it would seek federal approval for a Transco natural gas pipeline expansion in Virginia and North Carolina.

The $298 million Virginia Southside Expansion, scheduled for service by 2015, would move 270,000 dekatherms of natural gas to the nearby markets.

The Transco Pipeline is a 10,500-mile interstate system bringing natural gas from the Gulf Coast to the Northeast. The system moves about 9.7 million dekatherms per day, with a dekatherm being equivalent to one million British thermal units of energy.

Williams Partners gets FERC approval for pipeline

Williams Partners LP said Wednesday that it received federal approval for a $341 million expansion of the Transco natural gas pipeline, which should expand capacity in the Northeast by this time next year.

Williams said the project will expand the Transco Leidy Line and Transco mainline in Pennsylvania and New Jersey, to transport natural gas to the Northeast. It will add 12 miles of new pipe, mostly along existing pipeline routes, and a compressor facility in Essex County, N.J.

Construction of the compressor station begins this month, with pipeline construction starting in the spring. The new line should be in service by November 2013, the company said.

The project needed approval of the Federal Energy Regulatory Commission.

Corrosion cited in Alabama pipeline explosion

A corroded pipe has been deemed the culprit of a massive natural gasoline explosion in Sweet Water, AL last December.

A Transco natural gas pipeline ruptured at approximately 3:07 p.m. Dec. 3 with an explosion that could be heard for more than 30 miles while shooting flames nearly 100 feet in the air for over an hour.

The pipeline was shutdown immediately after the failure as firefighters battled the blaze for the next 90 minutes.

“Although we have systems and processes in place to prevent and identify corrosion, our investigation indicated there were multiple factors working in conjunction that led to this problem not being recognized,” said Transco spokesman Chris Stockton. “Extremely corrosive soil conditions, combined with failures in the pipeline’s protective coating and cathodic protection system ultimately weakened the pipe, causing it to rupture.”

Stockton said the rupture forced the company to make several changes in its corrosion control program.

“These changes are designed to more closely monitor levels of pipeline protection from corrosion, assure a higher degree of protection equipment uptime, and provide higher standards for levels of corrosion protection,” he said. “We are also continuing our investigation into this failure to better enhance our corrosion control procedures in the future.”

Williams Gas and Pipeline has also been working under a PHMSA (Pipeline and Hazardous Materials Safety Administration) Corrective Action Order, which details actions required to be completed to ensure the safety of the pipeline prior to putting the pipeline back in service. In addition, he said, the company is taking steps above and beyond regulation to ensure the pipeline is safe.

“All anomalies are being carefully investigated and any metal loss indications will be repaired prior to placing the pipeline back in service,” Stockton said. “Once all anomalies have been repaired, the pipe will be hydrostatically tested, which involves filling the pipe with water and pressure-testing it at considerably higher pressures than our normal operating pressures. Once all of these tests are complete, we will seek PHMSA’s permission to restore the line back to service.”
