The first event occurred when MI compressor 1855 was shut down to repair an integrity concern. When the MI compressors are shut down MI is backed out of the system gradually to allow the plant to adjust to changing process temperatures and levels, thus avoiding a more severe plant upset. Total duration and volume for this event were 2 hours and 14 minutes and 2,180 MSCF. / The second event was during restart of the same machine. Logic problems caused 1855 to require four restart attempts. Three times the machine had to be shutdown and blown down before logic was fixed and a successful restart was achieved. Total duration and volume for this event were 1 hour and 1,161 MSCF. Please call or email if you need additional clarification.

Total duration was 1 hour and 36 minutes, total volume was 14,139 MSCF. The second event was a process gas leak on Tic 1805 at 14:14 resulting in the stabilizer overhead venting to flare. Total duration was 1 hour and 6 minutes, total volume was 3,554 MSCF. During the same period of time, Tic 1805 was depressured to 0 (via the flare). Depressuring began at 14:14 with a total duration of 2 hours and 6 minutes of intermittent flaring and a total volume of 387 MSCF.

This is a note giving you a courtesy "heads up" on the greater than one hour flare events you will be seeing in the monthly gas disposition reports prepared by the Anchorage Volume Accounting Team. * GC3 experienced three flare events on June 24, 25 and 26 due to K5500 shutting down on high lube oil temperature. Temperature probes, RTD's and switches were changed out during the three days in attempts to eliminate that root cause of the shut downs. K5500 procedures were followed to minimize flaring. Total volume for the three events was 1,261 MSCF, total duration for the three events was 7 hours and 17 minutes. * FS1 experienced one extended flare event beginning at 10:00 June 17 and ending at 02:45 June 18 when the 1801 STV/IP compressor shut down due to high ambients. Several attempts were made to restart and reload the machine. Total flare volume for the event was 8,491 MSCF over 16 hours and 45 minutes. * GC2 experienced two flare events on May 30 and 31 due to PLC malfunction in the produced water section of the plant. The production cuts resulting from the water section upset caused the skid 18, IP and LP compressors to surge intermittently due to the low GC oil rate. The compressors loaded up as GC2 oil rates returned to normal. Total volume for the two events was 920 MSCF, total duration was 5 hours and 31 minutes. * ~experienced two flare events on June 17 and 18. The first event occurred when the 1884 tandem shut down 3 times due to high ambient temperatures over a 2 hour period. Each shut down resulted in 15 minutes of flaring. This event should have been captured as three separate flaring events and should not be considered as a greater than one hour event. The second event occurred when the 1805 MI compressor shut down a recycle trip while loading the boosters. Flaring stopped when 1805 was restarted. Total duration for the 1805 event was 1 hour and 14 minutes, total volume was 8,677 MSCF. * LPC experienced one flare event on June 17 when the 1808 gas reinjection turbine shut down. Flaring stopped when 1808 was restarted. I oaf2 6/28/20047:02 AM GPB Flaring Incidents ~Gas was cut during the event to reduce flare volume. Total duration for the event was 1 hour and 16 minutes, total volume was 5,804 MSCF. * FS3 experienced two flare events on June 17 and June 20. The first event occurred when the 1801 STV/IP compressor shut down due to high ambients and plant upsets. After three failed restart attempts, the spare machine (1802) was started, ending the flare event. Total duration for this event was 1 hour and 10 minutes, total volume was 466 MSCF. The second event occurred when the 1806 gas lift machine shut down due to instrumentation problems. 1806 was secured and depressured, ending the flare event. Total duration of the event was 6 hours of intermittent flaring totaling 685 MSCF. If you require additional information, please do not hesitate to call me.
