CGF shutdown Boosters 1801 & 1802 to repair wiring on the governor control. This in turn caused Tandem compressor 1885 to shutdown which caused high back pressure on the gas transit line causing GC1 & GC2 to automatically go to flare (for reaching their pressure safety limits). 1.1 BCFPD of gas was immediately shutin, but the flare valve at GC1 did not reset for 2 hrs and 13 mins (5450 MSCF) due to high pressure on the gas transit line/plant inlet HP separator and finally the suction knockout drum. GC2 flared for 45 minutes (938 MSCF) before their flare valve reset. Also, FS2 took A gas train down for vessel inspection/recertification. This requires depressuring the train to atmosphere, so the gas was sent to flare. A total of 378 MSCF was flared intermittently over 2 hrs and 20 minutes. It takes an extended period of time in order to completely depressure to 0 psi. Please don't hesitate to call me with any questions.
