Texas Eastern Pipeline Remains Shut after Kentucky Blast

The section of Texas Eastern pipeline that got damaged in a fatal explosion near Danville, Kentucky on last Thursday remains shut. The company is working with federal and state officials to investigate the incident. 

U.S. National Transportation Safety Board assumed control of the incident site and the company is supporting the investigation, Enbridge said. According to the Refinitiv data, about 1.7 billion cubic feet of gas was flowing through the damaged section of pipe toward the Gulf Coast at the time of the blast, from the Marcellus and Utica shale in Pennsylvania, Ohio and West Virginia.

The company said that Texas Eastern has three lines, Line 10, 15 and 25, between its Danville and Tompkinsville compressors in Kentucky and the blast occurred on Line 15. The three lines make up its 30-inch pipeline system.

Enbridge has not estimated when the damaged section of pipe will return to service at this time and has restricted north-to-south gas flows through the Danville compressor to zero.


North Dakota's TransCanada Keystone Pipeline Spill Likely From Crack Occurring During Install

The National Transportation Safety Board reported that the November 2017 TransCanada Keystone Pipeline spill that leaked in South Dakota was likely caused by an expanding crack that first happened during the installation phase.

The crack ended up leaking 407,000 gallons and probably occurred from a metal-tracked vehicle damaging the pipe, according to the report that was issued on Thursday, July 5th. The leaked oil was twice as much as the initially reported estimate, making it the 7th largest spill of onshore oil or petroleum product since 2010, as reported to the U.S. Department of Transportation.

Keystone’s detection system detected the spill and shut down the pipeline, but crude oil still spilled.

No injuries were associated with the incident and TransCanada was able to resume the pipeline’s use 12 days after the leak.

U.S. Safety Board to Begin Investigations Relating to Fatal Colonial Pipeline Accident

The U.S. National Transportation Safety Board is conducting an open investigation relating to the gasoline fire and explosion in near Helena, Alabama, which occurred last Monday and killed one worker and injured several others.

A section of Colonial Pipeline’s 5,500-mile Line 1 pipeline caught fire and erupted Monday in Shelby County, Alabama, just a mile near a section of the line that leaked hundreds of thousands of gallons of gasoline into a mine retention well and shut down gasoline to the U.S. Southeast for over a week.

The board announced Friday that a team of five members from the board will be in Alabama for several days to conduct interviews and collect evidence of the accident. Some will also visit Colonial Pipeline offices in Georgia to interview operations and engineering staff as well as to collect documents and data.

The fire that erupted on the line Monday during routine maintenance operations was finally fully extinguished on Friday, and operations have begun to remove residual gasoline from the pipeline and to replace the faulty section.
