Transco

Transco will perform piping modifications at North Padre Island Block A42 beginning Thursday. The work is expected to last two days; during that time no flow will be allowed at North Padre Island Blocks 892/893 and A12 or at Mustang Island Blocks 31A and 31B.

Initial work was completed early this month on Transco’s McMullen Lateral in South Texas in conjunction with a state highway widening project (see Daily GPI, Sept. 19), but additional maintenance will be required Wednesday and Thursday. All flows upstream of Milepost 47.866 on the lateral will be shut in at that time, affecting about 35 MMcf/d. See the bulletin board for a list of affected points.

Transco completed construction work at Station 35 and station capacity was nearly back to normal as of Friday afternoon, a spokeswoman said. The project, which was causing an allocation bottleneck at downstream Station 40, began in May and was originally scheduled to end July 1 but got delayed (see Daily GPI, July 23). There will be additional commissioning outages in coming weeks that will restrict Station 40 capacity temporarily, but most will be only one day long, the spokeswoman said.

The New York Mercantile Exchange (Nymex) will launch over-the-counter (OTC) energy clearing services for 25 of the most commonly traded OTC energy contracts, giving the energy markets new products to trade, much needed trading security and new trading flexibility. Nymex plans to launch the services on May 31.

Transcontinental Gas Pipe Line has placed its Sundance Expansion Project into service, increasing capacity by more than 236,000 Dth/d mainly for traditional markets and new power plants in Georgia and the Carolinas. The project includes four pipeline loops, totaling 38 miles, along the company’s existing mainline system and 41,225 hp of compression at two existing compressor stations in Georgia — Station 115 in Coweta County and Station 125 in Walton County.

Transco lifted Monday a restriction on scheduled quantities through Station 40 in East Texas to primary firm transportation only; it had been imposed Thursday (see Daily GPI, Sept. 27). The pipeline also ended Monday a restriction on due-pipeline imbalance make-ups but said it will maintain a limit on positive imbalances at all pooling points.

Tennessee lifted a pro rata seal through Secondary Services atthe Transco Rivervale meter Wednesday but replaced it with asimilar one at the Algonquin Mendon meter.

After raising its IT availability into the Zone 6-NYC pool to itshighest level in more than a month Tuesday (see Daily GPI, Jan. 11), Transco said that effectiveFriday there will be only about 25,000 dth/d of IT available throughthe Linden (NJ) Regulator Station and zero IT upstream of Station 90and on the Leidy Line for deliveries downstream of Centerville, NJ.

Transco continues to ratchet upward IT availability into itsZone 6 market-area pool. Effective today until further notice, thepipeline said Monday, 100,000 dth/d each of interruptible capacitywill be available through the Linden (NJ) Regulator Station and forLeidy Line deliveries downtstream of the Centerville (NJ) RegulatorStation. It will offer another 100,000 dth/d of IT between Stations90 and 180 in Tiers I and II, but zero will be available in TierIII (Station 180 through East).
