Enbridge Inc. on Sunday restored partial capacity on a section of the Texas Eastern Transmission (Tetco) system in southeast Ohio, about a week after part of the pipeline was damaged in an explosion.
The company managed to return Line 25 to service, one of the 30-inch pipes in the same right-of-way as Line 10, which exploded south of the system’s Berne compressor on Jan. 21 in Noble County near Summerfield, OH, cutting flows through the station to zero. Tetco said about 1.6 Bcf/d of north to south flows through Berne have been restored now that Line 25 is back online.
Genscape Inc. said early Monday, though, that only 511 MMcf/d was scheduled through the compressor.
Line 25 was isolated with Line 15, which remains closed, to inspect their integrity after the blast. Tetco said over the weekend that it isolated more of Line 10 between the Athens, OH, and Uniontown, PA, compressor stations, which are respectively downstream and upstream of the Berne station. That cut flows through Uniontown by about 200 MMcf/d to 4.1 Bcf/d, which has since been restored.
The remainder of Line 10 is isolated. The explosion cut about 1.4 Bcf/d of natural gas flows on that line. The blast injured two residents and damaged three nearby homes. An investigation is underway to determine the cause. There is no timeline for repairs.
