An engineering inspection determined that the equipment must be shut down for repair. The GHX plant was shutdown at 21:00 on December 21. The GC1 plant stayed on line with limited production at -50 mbpd and a gas rate of 1045 mmscfd the normal through put is approximately 100 mbpd and 2.5 bcfpd. This shut down resulted in a lack of IP /LP available gas for compressors K - 105 and K -107 which resulted in back pressure in V -136 which is relieving to the LP system resulting in a clean vertical flare of approximately 6 mmscfd. All potential and controllable options to reduce flare volume have been taken into consideration and acted upon. There are two crews working 24 hours a day to repair the vessel as soon as possible. This requires a safe out and entry into the vessel to inspect the welds that make up the water boot to the vessel. We will not know the duration of the incident until the vessel has been entered and inspected. If you require additional information, please don't hesitate to call me.

Steve & Jim, I got this response from the GC-1 Ops Lead regarding the GC -1 pilot purge increase: ::; "No Flare work was done. The pilot gas was increased due to black smoke, wisping. We are currently max scale, above 480 mscfd. We are reducing that rate down to 400 mscfd immediately. The Rover is aware of this situation and will be monitoring. The plant will also be surveyed to see if we have any PSV's leaking." WHR means "waste heat recovery". Let me know if you need more information.

If this increasing trend is linked to something specific - e.g., the flare tip changeout - then it would be helpful to know what the usage volume will stabilize at (most other facilities show stabilized rate for pilot -purge gas); if there are other reasons for the increasing trend. we would like to know what they are. Not sure if you were involved in the discussions at FS -3 but it turned out the increasing volumes being reported were finally attributed to leakage past PSVs and the apparent lack of testing and maintenance of those valves. Took some investigating/reviews to get to the real cause. We want to make sure this or similar circumstances are not the case here. Thank you for looking into this; if you prefer, I am available to discuss directly with appropriate facility /engineering personnel. Jim Regg AOGCC Benson. Gary A wrote: Steve & Jim, I've sent a note to the Slope requesting an explanation of the increased pilot purge. Just to clarify, the volume has been in the 44- 45,000 mcf per month range for 2005 until October when it jumped to about 50,000 mcf. So that's a 5 -6,000 mcf per month increase since October, not a 10,000 mcf per month increase since July. Or am I misunderstanding your note below?

PBU GC -1 flaring from July thru December 2005 shows a large volume increase, an upward trend of over 10,000 mcf for the period. Why the large increase? Does this increase have anything to do with flare tip change out and if it does, what would the future target rate be for the pilot purge at GC -1? Looking back over the recent history (beginning April 2002 thru June 2005), it appears flaring increase 10,000 mcf in a 3 year period and recently there has been that much of an increase again. They had flare tip change out last Summer. Please provide an explanation of the increase flare for this duration and what BP will do to mitigate the problem leading to larger volume flared at GC -1.

Both events resulted from problems with GC1 process automation. The first event began at 22:35 on February 27 and lasted for 3 hours and 13 minutes. Total volume for this event was 4,979 MSFC. The second event began at 22:02 on March 2 and lasted for 2 hours 19 minutes, this event was closely followed with a full plant shut down that caused a 1 hour and 52 minute flare event. Total volume for the second event series was 5,055 MSCF. After the first event, the process automation techs changed out a bad power supply on an I/O processor. The second event resulted in a change out of a data highway that was associated with the previously worked on I/O processor. An extended flare event is in progress at GC2. The event began at 0700 on March 2 when GC2 was shut down due to a leak in the oil transit line. 2 MMSCFD of stripping gas and water tank purge gas is being maintained to keep the plant warm. We intend to maintain this condition until the plant can be restarted. Likely duration of the shut down is unknown at this time.

During this period, the ambient temperature increased from -5 to +20 deg. The GC1 LP /IP compressor bundles were originally designed to pump a heavier mole weight gas and these machines are scheduled to be rewheeled this summer due to their inability to handle leaner gas now coming from the reservoir. The combination of increasing ambients and the inability of the GC1 LP /IP compressors to pump leaner gas resulted in intermittent flaring. Gas production from GC1 has been reduced to prevent this condition from continuing. Intermittent flaring occurred over 34 hrs and 53 minutes, total volume flared was 10,174 MSCF If you require additional information, please don't hesitate to call me.

The events occurred at GC1 (6/21 -23), GPMA (6/21 & 22), and FS1 (6/21). The GC1 flare event began after a full plant shut down at (1830 6/21) caused by an automation glitch. Due to the combination of low oil rates as the plant was coming back on and high ambient temperatures, the IP and LP compressors failed to load up. A second automation glitch knocked the plant back down at 2115 on 6/23. Flaring continued intermittently across both events until sufficient oil rate was brought on to enable the LP and IP compressors to load up. Duration of intermittent flaring was 40 hours and 58 minutes, total volume flared was 15,323 MSCF. Two extended flaring events occurred at GPMA. The first event was a shut down of the STV /IP compressor 1801 due to bad exhaust stack temperature switch. Restart of 1801 was hampered due to a bad fire eye. Duration of the event was 3 hours and 12 minutes of intermittent flaring. Total volume was 778 MSCF. A second event occurred at 1306 on June 22 when STV /IP compressor 1800 shut down due to high discharge temperature which was a result of high ambient temperatures. 185 MSCF was flared during the 61 minute intermittent event. On June 21 at FS1, a planned depressuring of the A -HP separator, scrubber and liquid pot for blinding occurred. Duration was 3 hours and 30 minutes, total volume flared was 128 MSCF. If you require additional information, please don't hesitate to call me.

In preparation for the GC1 turn - around, rate was reduced to perform a full plant ESD test. With the reduced rate, there was insufficient oil rate to allow the IP /LP compressors to bite. Duration of the event was 5 hours and 25 minutes of intermittent flaring, total flared volume was 2,708 MSCF. The event ended when the ESD test was performed. Following the ESD test, the plant and associated equipment required depressuring for safe -out activities. Depressuring for safe -outs continued for 11 hours and 15 minutes, with a total volume of 1,630 MSCF. 1 of 1 7/18/2006 10:44 AM 1 Facilir Number 0290000031 2 Facih Name N � PBU GC 1 3.

IP compressor K207 experienced a seal leak on Aug 19 and requires a new seal. The spare IP j machine (K208) has a short in the motor, requiring the motor to be replaced and therefore is unavailable at this time. Due to the current circumstances at GPB, we have determined that leaving the plant partially running during the K207 maintenance is the most prudent course of action at this time. We have taken the following actions to minimize the total flare volume: 4$ K 70F We are anticipating completion of the work and K207 restart late Tuesday - early Wednesday, Aug 23.
