Columbia Gas said its Line SM-123 will be out of service today and Wednesday due to a tie-in of a relocated portion.

NGPL said Monday a system leak at the Torch High Island 71 platform (see Daily GPI, Nov. 27) has been repaired and it resumed scheduling nominations for three affected receipt points.

NGPL also reported completing work on its #1 line in Segment 22 between Compressor Stations 301 and 302. Effective for today’s gas day, NGPL was accepting nominations of gas sourced out of the South Texas Zone for deliveries north or east into the Gulf Coast System. Repairs on the #2 line in Segment 22 will take place in 2002, the pipeline said.

Reliant declared a force majeure Monday, saying the electric unit at Buckley Compressor Station will be unavailable for about three weeks due to a cracked pulsation bottle. Higher pressure than normal may be experienced on Lines S, ST-1 and ST-10 during this outage. Reliant also said that due to maintenance on the Amber Station’s #3 compressor, West of Amber capacity is expected to be limited to 360,000 Dth/d through Friday.

In-line inspection work on the South Lateral has been completed, NOVA said, allowing an IT restriction in Segment 22 to be lifted Monday.

Sonat shut in the Placid Plant Station receipt point Monday and today for the installation of new equipment. The pipeline treated the shut-in as a force majeure action.
