Rev 6/22/97 Flare report information ~ ~ M Subject: Flare report information Date: Fri, 8 Jan 1999 19:15:47 -0500 From: "PBU, NS Optimization Engineer" <PBLTNSOptimizationEngineer@bp.com> To: "'wendy mahan"' <wendy_mahan@admin.state.ak.us> CC: "PBU, Prod Opt TL" <PBUProdOptTL@BP.com> Wendy, Per our phone discussion I have received the following information from GC3 regarding the 10/26 and 10/28-29 GC3 flaring events. A key point is highlighted in bold print in the explanation for the 10/26 event. I am sure that we will become much more proficient at troubleshooting and restarting K5500 as operations gains experience with this piece of equipment. Along with that proficiency will come improved estimates for restart timing, thus improving our ability to make the judgment call that a restart is imminent or that additional steps (a full plant shut down is required to completely stop flaring) must be taken to reduce or stop flaring. If you require additional information, please do not hesitate to contact me via email or at 659-4382. Also please respond to this email so that I can be sure it made its way through the BP network to your desk top. Thank you, Hal Tucker 10/26 Reason for flaring: K-5500, wet gas compressor, shutdown. GC3 had several start attempts during the troubleshooting exercise. GC3 ultimately had to abandon a pair of wires and switch to a spare pair running to the position limit switch on the suction SDV. The two things causing the delay in this instance were a wire or pair of wires that generally don't just fail and the compressor is new to GC3 and the operators have little history regarding its operation yet. GC3 also replaced a PLC output card. During this time GC3 felt that they were on the verge of getting it restarted. 10/28-29 Reason for flaring: K-5500, wet gas compressor, shutdown. K-5500 had been S/D due to electrical work on the suction valve. Start-up was attempted but was held out due to an oil injection pressure transmitter fault (PAXX-5220). Controls techs ensured that the transmitter was calibrated and working correctly. After an attempt was made to start the machine with the Aux. lube oil pump in the hand position, a low level in the lube oil vessel (VSP-5500) was encountered. Lube oil was added and the vessel repressured clearing the transmitter fault. Subsequent restart attempts were unsuccessful as the compressor shut down immediately due to low suction pressure. After the suction pressure was increased twice, it was determined that the compressor was trying to load up too quickly causing a shut down due to low 1 of 2 1/11/99 8:13 AM Flare report information suction pressure. Restart was then attempted with the capacity control in local control instead of PLC control. By preventing the machine from loading beyond 10% capacity the machine remained on through the warm up period. After a successful warm up (suction and discharge valves both open) the compressor was slowly loaded. At approximately 96% capacity the capacity control was switched from local to PLC and returned to normal operation. 2 of 2 1/11/99 8:13 AM ALASKA OIL AND GAS CONSERVATION COMMISSION FACILITY REPORT OF PRODUCED GAS DISPOSITION Facility Operator Field(s) Month/Year of Disposition GATHERING CENTER 3 BP EXPLORATION ALASKA WESTERN OPERATING AREA-PBU Sep-98 • • Disposition 1.
