Sea Robin began unscheduled maintenance Tuesday at East Cameron 265; it is expected to last through Wednesday. Operators upstream of Vermilion 149 could experience lower pressures and pressure fluctuations as a result. Deciding to conduct other work in conjunction with the East Cameron 265 project, Sea Robin plans to perform annual maintenance at the onshore Erath (LA) Compressor Station and pigging from Vermilion 149 to the onshore Devon processing plant on Wednesday and Thursday, which could lower daily pressures downstream of Erath and will reduce capacity at the Sea Robin-Trunkline interconnect. The East Cameron work has been postponed three times since early May (see Daily GPI, May 6).

NGPL continued to work Tuesday with operators of three receipt points in trying to allow production that had been shut in after a Friday morning rupture in the pipeline’s TexOk zone to resume a limited amount of flow (see Daily GPI, May 17). NGPL had authorized 25,000 Dth/d each in Tuesday gas day nominations at the Enbridge/Panola, GulfTerra/Panola and EastTrans/Panola points, and said the volumes were being raised to 75,000 Dth/d at each point for Wednesday’s gas day. Those locations are dually connected to NGPL’s Gulf Coast #1 and #2 mainlines, which were not damaged by the blast. Shut-ins remained in force at 10 other points connected to the Gulf Coast #3 mainline, which was the one that ruptured. NGPL repeated that pipeline segment capacity is not impacted at this time and it does not anticipate curtailing primary firm or in-path secondary firm transportation service or any firm storage service.

Without setting a bidding timeline, Northwest said Tuesday it seeks to buy about 400,000 dekatherms at fixed prices for system use. Northwest wants to acquire the gas “on an ongoing basis until the needed quantity has been fulfilled.” The pipeline said it will consider sale offers at any valid receipt point based upon price and operational conditions, but currently would be unable to receive purchased gas south of the Vernal (UT) Compressor Station “due to the fact the primary firm shippers are fully utilizing the available capacity there.” See the bulletin board for details.
