Unplanned

Citing unplanned engine maintenance at Buttermilk Compressor Station in its Southwest Gathering Area, ANR said based on high line pressures and current operating conditions it was required to reduce receipt nominations at its CenterPoint interconnect in the area to zero Tuesday through Dec. 10.

Transco said it is conducting unplanned maintenance to repair a leak on its Southeast Louisiana Lateral in Terrebonne Parish, LA, and asked operators of receipt points upstream of the affected area to shut in immediately. The outage affects flows of about 100,000 Dth/d, and Transco said effective Tuesday it was not scheduling or confirming quantities at the upstream points until the maintenance is complete, which it estimated will take seven days.

Citing a possible leak, ANR said it is performing an unplanned pipe inspection on its 747 Line that requires the shut-in of four South Marsh Island meters offshore Louisiana.

ANR said it began unplanned engine repairs Monday at Bridgman Compressor Station along its Michigan Leg South, which reduced total St. John W-E (west to east) capacity by 265 MMcf/d (leaving 1,030 MMcf/d available) until further notice. Based on current nominations, ANR anticipates that the reduction may result in the curtailment of IT and Firm Secondary nominations.

Due to a possible leak, ANR said Thursday it would begin unplanned pipeline inspection on the 708 Line in the Southeast Area Fuel Segment, causing the Cheniere Perdue location to be shut in until further notice.

Tennessee said Wednesday it was lifting a systemwide OFO Action Alert against positive imbalances.

ANR said unplanned pipe maintenance due to a possible leak at Eugene Island 188/189 offshore Louisiana is now expected to keep the point shut in until Sept. 30.

ANR reported shutting in the Eugene Island 188/189 meter offshore Louisiana until Sept. 15 to perform unplanned pipe maintenance “due to a possible leak.”

Texas Eastern said an unplanned outage at its Five Points (OH) Compressor Station (see Daily GPI, May 15) has been resolved and the station was returned to normal operation Friday. All restrictions on its 24-inch diameter system in the area were removed.
