The cause of the event was a failure in a PCM which disrupted instrumentation and control of both GC1 LPS machines. All GC1 and Pt. Mac 2 low pressure production had to be shut in to stop flaring. The extended event began at 09:57 and ended at 11:10 for a duration of 73 minutes, with a total flared volume of 12,674 MSCF. Per your request for courtesy notification of events that exceed 5,000 MSCF in volume, an event earlier on March 19 resulted in a flared volume of 6,646 MSCF. The duration of this event was 29 minutes (04:57 - 05:26). This was the initial failure associated with the PCM that eventually resulted in the 73 minute event noted above.

The first event is a follow up to the flaring events at GC2 described in Dwight Warner's April 14 e -mail. GC2 continued to experience intermittent flaring from K205/K208 through April 14 and 15 until 12:13 AM on April 16 when sufficient process heat was restored to enable second and third stages to break out enough gas to allow K205/K208 to maintain forward flow. Process heat, from the turbine /compressor K7000 Waste Heat Recovery Unit, was restored once repairs to the combustion section of K7000 were completed. The damage to the combustion section was discovered during routine maintenance. During the flaring event, operations cut total field gas rate and gas rates at all 3 GC's to reduce the back pressure on K205. Additionally, process changes (decreased gas cooler temperature to increase condensate yield, and increased suction KO drum temperature to increase flashed gas) were made to increase the available gas volume to the suction of K205. These changes enabled K205 to intermittently attain forward flow and thus reduce flare volumes: Flare duration and volume [in addition to what Dwight has already reported] were 46 hours 23 minutes and 50,175 MSCF. For approximately 23 hours of that duration, flaring was intermittent. An extended event occurred at GC1 on April 19. The event was part of the turbine cool down procedure in preparation for routine water washing. The flaring event began at 1658 and ended at 1840 (102 minutes), the total volume flared was 3,188 MSCF. The third event, which occurred at FS1 on April 19, is being reported at your request. This event had a volume of greater than 5,000 MSCF. Turbine /compressor 1804 shut down on a vibration alarm. The flaring event began at 0627 and ended at 0720 (53 minutes), the total volume flared was 6,592 MSCF. If you require additional information, please don't hesitate to call me.

The flaring began at 00:00 and ended at 24:00 (1440 minutes), total volume flared was 73 MSCF. This event began 8/10; total volume flared to date is 365 MSCF. Vessel work is ongoing. GC1 flare whilst depressurizing C slugcatcher, 8/16 An extended flaring event occurred at GC2 on 8/16 in preparation for a planned TAR. The C slugcatcher was used to de- pressure LDFs from E and G -pads; the gas remaining once the slugcatcher had been drawn down to the lowest pressure possible with the LP compressors was flared, between 01:04 and 02:39, a total volume of 660 MSCF. GC2 flare during TAPS pro- ration, 8/16 An extended flaring event occurred at GC2 on 8/16 during the TAPS pro- ration. In order to meet the 36% pro- ration, rate was cut, reducing the flow to the LP compressor to such a degree that it shut down. Wells were re- routed to bring more gas to GC2, and the compressors were successfully restarted. Flaring took place between 14:12 and 15:57, a total volume of 1094 MSCF. GC2 flare during slugcatcher PSV work, 8/16 An extended flaring event occurred at GC2 on 8/16 during work on the B slugcatcher PSVs. The slugcatcher was de- pressured, and flaring took place between 08:20 and 09:00, a total volume of 556 MSCF. The flaring ceased when the slugcatcher was depressured.

I notified Jim Regg by phone on the 29th once the uncontrolled release was contained. The estimated volume associated with this release was 2.775 MMSCF which was sent on 10/1 to AOGCC in the 5 day report. A follow -up 30 day report will be submitted to the AOGCC once BP completes their investigation of the incident. The incident review should be completed next week. At that time it will require inspections and line replacement to be able to bring P -Pad and Y -Pad back on line. The expected duration of these pads being shutdown is not known at this time. In order to insure that the LDF coming from P/Y Pads did not freeze it was necessary to purge this line. This was completed on 9/29 in the evening, but I am still awaiting the volumes to report to you. I have provided the flare report that is in the system below, but the volume needs to be entered once engineering has completed the calculations. An extended flaring event occurred at GC1 on September 29 when the Y/P Pad LDF was depressured to avoid freezing after the Y -Pad gas lift line incident. The flaring began at 21:30 and ended at 23:37 (127 minutes), total volume flared will be provided by Monday 10/5. If you require additional information, please don't hesitate to call me.

Jim and I find this report lacking in several respects. Please send us a more detailed summary of the investigation with - Root cause analysis - why did this line rupture? - Events leading up to the rupture - were there any indications of a leak? - was work oin on with the line or shut -down devices at the time of the failure? 9 g - Metallurgy? - Corrosion? External /internal? - summary of how the safety systems performed in response to the failure - schematics showing the line, ESDs - pressure plots up and downstream of line before /after the event. - If an anomoly indicating a potential leak - prior to the break - please also show that, and when this was noted. - metalurgy report - evaluation or plans for evaluation of risk associated with other gas lift lines - details of how you will address any other risks - where are the high risk areas, how will you inspect, do you see indications elsewhere of problem areas? - Is your investigation complete? If not please provide a time -line of your planned activities. In review of the September gas disposition report for GC1, the volume noted for the depressurization of the Y- LDF was 854 Mscf. The leak of gas was not reported on this form (which had been stated to be 2.66 MMscf on the incident report. The form needs to be revised to include this. In addition, we want to know the details of how you determined the volume. See the attached e-mail sent from Jane Williamson to James Chesher on Oct. 11, 2008 concerning requested information. • 11/20/2008 Y -pad gas release September 29, 2008 - 30 day report Page 2 of 2 Please provide this information as soon as possible.

A well disconnect crew of nine employees was working at Y -5 and Y -9. An additional grease crew of two employees was working outside skid 62. The pipeline involved was the P -496 (GLT- P- 8 "/89) with the following characteristics: • Diameter: 8.625 -inch OD • Wall Thickness: 0.312 -inch • Specified Material: API 5L X60 • Design Pressure /MAOT: 2160 psig @ 100 ° F • Operating Pressure: 1900 -2000 psig Safety systems were online and fully functional, although pressures did not exceed operational set points and therefore were not triggered. Safety device set points are: Safety Device WOA PSDH 2063 psi PSV 2130 psi As per the safeout, the Gas Lift GLT Y Shut Down Valve (SDV) 6988 was closed at approximately 12:14. SCADA information documents that pressure increased from 1866 psi to 1939 psi over a ten minute period, not exceeding the operating range. At 12:20, the Y Pad Well Pad Operator heard a loud gas release and felt a vibration. The operator went outside and observed the 8" GLT supply line to P Pad coming from behind the 507 MI skid after it had parted. The Area Operator and all crews shut down their equipment and evacuated to a safe area. The Pad Operator called for a Y Pad shut in and requested the Emergency Response Team. Incident Response The GPB Emergency Response Team was dispatched. The incident scene was secured and the evidence collection team was activated. The appropriate regulatory agencies were notified, including the AOGCC, the PSIO, and EPA. Sequence of Events (Timeline leading up to, during and after incident) Date Time (Times are approximate) 1998 Insulation was removed at a pipeline anchor adjacent to the failure site. Insulation was removed to evaluate welded components for manufacturing defects. No defects were observed. In accordance with the approved practice for gas pipelines at that time, the anchor was not re- insulated. The failure location is at the site of the insulation edge. 2003 The insulation edge area in the vicinity of the failure was excluded from the 2003 external inspection schedule. Inspection notes indicate the area was covered in snow at time of the scheduled inspection. Sequence of Events — Cont'd 2008 Inspection layout of the pipeline was completed in preparation for an external corrosion survey. The segment at the failure site was included in the planned survey. The inspection had not started prior to the failure occurring. Sept 29, 2008 Y & P Pad are under normal operations. Permitted work crews are located at Skid 62, wells Y -5, and Y -9. Y &P Pad Operator started safeout for the GLT Slot Y -09 for the upcoming rig work over. 1210 SDV 6988 was closed for the GLT safeout and HVY 5100 was 2/3 open. This action isolated GLT supply to Skid 62 while leaving GLT supply to P -Pad and Skid 96 operational. 1214 As a result of closing SDV6988, the Pressure Transmitter PTY6989 showed significant pressure drop downstream of SDV 6988 due to the bleed down from HVY5100. 1214 Pressure increased from 1866 psi (PTP3108A) to 1940 (measured upstream of SDV 6988 over a 10 minute period. 1220 Operator went outside and observed the 8" GLT supply line to P -Pad had parted. Area Operator and crews working on the pad shut down all equipment and evacuated. 1224 Peak pressure of 1939 psi on P3108, which did not exceed the maximum allowable operating pressure. 1230 Pad Operator called for Y -Pad Shut In. 1235 Pad Operator called BP radio and requested ERT. 1245 GLT & MI Shut In for both Y- and P -Pads; and Well Shut In for P -Pad; Pad Shut Down for Y -Pad. Investigation The investigation team was formed and convened on October 1, 2008. The team Summary complied with the Terms of Reference and followed the investigation process as outlined in BPXA's Incident Investigation Manual. The investigation has been completed and the investigation report is being finalized. Lab analyses are pending. Critical Factors The critical factors of the incident were determined to be: 1. The removal of a portion of the insulation in 1998 to evaluate pipeline anchor welds. The insulation was not re- installed, which was in accordance with the approved practice for gas pipelines at that time. The apparent location of the failure is the interface of the insulated and un- insulated sections of pipe. 2. Planned 5 -year external corrosion re- inspection in 2003 excluded this area due to snow drifts. No follow -up was conducted. 3. Pipe wall thinned due to external corrosion to the point where it could not contain internal pressure. Corrective 1. Develop a standard, which includes timing requirements, for mitigation and Activities reinsulation of pipelines and /or seal the ends on sections where insulation has been removed. 2. Develop and implement a scope and schedule to address historical back -log of uncoated, uninsulated pipeline inspection locations. This includes a prioritization based on risk. 3. Identify an execution plan for the reinsulation program of pipeline inspection locations, Use the scope and standard developed by the CIC group. 4. Develop and implement a process to track and close out missed CUI inspections. Ensure that any missed inspections are flagged and managed similar to overdue inspections of safety Critical Equipment and implement the Management of Change Process, if warranted. 5. Develop a scope of work and schedule for the evaluation of high pressure gas pipelines of similar wall thickness that were identified to have areas of increased corrosion potential based on risk assessment. 6. Develop the evaluation / mitigation plan on high pressure gas pipelines of similar wall thickness in those areas that were identified to have increased corrosion potential. bp BP Exploration (Alaska), Inc.

I notified Jim Regg by phone on the 29th once the uncontrolled release was contained. The estimated volume associated with this release was 2.77E 2.662 MMSCF which was sent on 10/1 to AOGCC in the 5 day report. A follow -up 30 day report will 10/9/2008 RE: GPB Gas Flaring Event and Incident at Y -Pad Page 2 of 2 be submitted to the AOGCC once BP completes their investigation of the incident. The incident review should be completed next week. At that time it will require inspections and line replacement to be able to bring P -Pad and Y -Pad back on line. The expected duration of these pads being shutdown is not known at this time. In order to insure that the LDF coming from P/Y Pads did not freeze it was necessary to purge this line. This was completed on 9/29 in the evening, but I am still awaiting the volumes to report to you. I have provided the flare report that is in the system below, but the volume needs to be entered once engineering has completed the calculations.

I notified Jim Regg by phone on the 29th once the uncontrolled release was contained. The estimated volume associated with this release was 2.775 2.662 MMSCF which was sent on 10/1 to AOGCC in the 5 day report. A follow -up 30 day report will be submitted to the AOGCC once BP completes their investigation of the incident. The incident review should be completed next week. At that time it will require inspections and line replacement to be able to bring P -Pad and Y -Pad back on line. The expected duration of these pads being shutdown is not known at this time. In order to insure that the LDF coming from P/Y Pads did not freeze it was necessary to purge this line. This was completed on 9/29 in the evening, but I am still awaiting the volumes to report to you. I have provided the flare report that is in the system below, but the volume needs to be entered once engineering has completed the calculations.

This caused Low and High gas alarms in Module 54, and the pad was shut down. Lou Grimaldi, AOGCC inspector, was notified by telephone at approximately 6.45pm. An unknown volume of gas was released - the volume will be provided on the 5 -day report. In order to secure the pad, the wells were shut in and flowlines and the LDF were depressured through the B- bank slugcatcher. This resulted in an extended flaring event, starting at 19:16 and finishing at 21:02, a duration of 106 minutes. The total volume of gas flared was 834 MSCF.

This was caused by a loss of electrical power to the CGF utilities section at approximately 20:58, which caused the tandems and booster compressors to shut down on high lube oil temperature. This increased the transit gas pressure, and several facilities (listed below) were forced to flare. Rate was reduced by shutting in high gas wells until CCP could handle the gas load from the field. The cause of the electrical shutdown is under investigation. CGF began coming back online at approximately 00:10, and was fully operational by approximately 09:00 on 10/15/08.

This was due to 1801 shutting down on an instrumentation trip and would not ramp up out of warm -up mode. 1801 was then manually shut down at idle speed, restarted and loaded. An extended flaring event took place at GC1 starting on 12/23/08 at 01:00 and stopping on 12/23/08 at 04:25 (205 minutes) with a volume of 5000 (MSCF). This was due to depressuring the Y/P LDF via the B slug catcher in preparation for line lifts and inspections. Please contact me if you have any questions.
