Columbia Gas (TCO) declared a force majeure following an oil pump failure on a unit at Walbridge Compressor Station in Wayne County, WV. Coupled with a Line P construction outage, the oil pump failure has resulted in the inability to receive production from meters on Lines BM-39 and BM-19, TCO said. Operating capacity at 18 meters was taken to zero Tuesday, while capacity at another meter was allocated downward by 14%.

Tennessee lifted a systemwide Imbalance Warning Saturday. The pipeline also rescheduled a line abandonment project for the 523M-7300 and 523M-7600 lines offshore Louisiana to Wednesday through Oct. 4.

As part of its 823X-1300 Line abandonment project, Tennessee will suspend physical flow from Monday through Sept. 22 at the Vermilion 51 and McIlhenney RIP 823X 1351 meters. Additionally, Tennessee said, this project will result in the inability to flow north from the Bluewater Pipeline, and in the event of a “liquid upset” all meters on Bluewater may be required to shut in. The work was moved up from previously scheduled dates of Sept. 1-31.

Xcel Energy said its Colorado utility will complete in October the upgrade of a six-inch diameter natural gas transmission pipeline to a 16-inch diameter line running in the west-central part of the state.

The utility added a third construction crew to overcome delays and keep the project on schedule.
