Valve

Trunkline shut in all receipts and deliveries between Cypress Compressor Station north of Houston and Gate Valve 32 after experiencing a rupture early Wednesday downstream of the station. No fire or injuries resulted from the break. All receipts upstream of Cypress must have nominated deliveries upstream of Cypress. Available upstream delivery points include Cokinos-San Patricio and DEFS Katy, the pipeline said. It encouraged shippers to call their downstream delivery point operators to see if they would be accepting gas from Trunkline during the outage. In a late afternoon update, Trunkline said the outage will extend through Friday’s gas day, but it would accept nominations through the shut-in segment for Saturday flow beginning Thursday. The affected section of pipe will be required to operate at a reduced operating pressure that will limit its capacity to 250 MMcf/d until further notice.

El Paso began emergency maintenance Wednesday on Line 1201 downstream of Valve City Station, reducing San Juan Basin capacity by 100 MMcf/d through Friday. Capacity of the North Mainline will also be reduced by 60 MMcf/d during the same period. El Paso extended the duration for unscheduled repairs of Bondad Station’s 2A turbine, causing a Bondad capacity cut of 100 MMcf/d, through Aug. 8. The pipeline previously had expected to complete the work Aug. 2 (see Daily GPI, Aug. 1).

Tennessee reported Wednesday it had discovered a pinhole leak in a valve on its East Cameron 49B compressor platform. While repairs are made Thursday through Sunday, physical receipts will be suspended at 13 upstream meters. Other meters will experience higher than normal pipeline pressure.

Tennessee will perform pipeline modifications Oct. 14-24 to the 500 Line at the Yscloskey Gas Processing Plant, located near Main Line Valve 529 in southeast Louisiana. The work will not impact available capacity on the 500 Line, but the Eloi Bay meter will be out of service during the entire period. In addition, Tennessee will be unable to deliver gas to Yscloskey for processing starting Oct. 14. On or about Oct. 18, Tennessee anticipates resuming deliveries of about 600 MMcf/d to Yscloskey, with full deliveries due again after Oct. 24.

Panhandle Eastern said an outage at the Louisburg (KS) Station to replace a gate valve will begin at 8 a.m. CDT today and last about one day and eight hours. The KN Pony Express point will be shut in during the work, affecting 75,000 Dth/d.

Texas Eastern said it had finished valve repairs on its Venice Lateral in the East Louisiana Zone (see Daily GPI, July 26) and brought the line back into service Thursday morning, allowing affected production to resume at scheduled volumes. Shipper imbalances incurred during the brief outage may be made up through the end of the month, Texas Eastern said.

El Paso will shut in Line 3079 (Lusk Line) in Lea County, NM, today for repairs. There will be no flow between Valve 1 and Lusk, affecting the IGCNMLSK, IMEWLUSK and IPHFUEL1 interconnects and any supplies south of Lusk destined for the San Juan Crossover. An Unauthorized Overpull Penalty situation remained in effect Tuesday for the El Paso system.
