Mullins Flow St2ti4n t Supervisor operations PRt315 sb7-659-5362 907-fi59.8732 On June 7, 1998, at 20:44 hours, the 1802 gas generator tripped off line due low hydraulic control pressure. Operations personnel Chec-ced the unit and found the hyl3ravtic oil reservoir empty and refilled the reservoir, but were unable to Iccate the Teak which had emptied the reservoir. Because the hydraulic oil pump does run unless the unit is starting or running, they attempted to restart the unit at 21:10 hours. The unit tailed to start tlt,e to tow hydraulic pressure; caused by air accumulation in the hydraulic controls system. After the gas generator roiled tc a stop and the shutdown sequence completed. the operator again attempted to start the unit at 21:19 hours. The second start sequence failed when the power turbine failed to reach the speed necessary to satisfy the start sequencer in th2 allotted time, and at 21:30 hours, the Lead Operator called out tvro InstrurnEnt teohnicians to assist in starting the unit. They arrived at 21:40 hours. Far safety rea3ons, and to facilitate finding the leak, the Qperators ~emdved the grating surrounding the engine and cleaned up the spilled hydraulic oil from beneath the turbine. They initiated a third start attempt at 22~t4 hcurs with the Instrument Technicians an site. During this attempt the operator monitoring the turbine was able to identify the leak and the unit wa3 shutdown for repair. Two of the hydraulic control lines had been rubbing together, warn through, and caused the leak. After replacing the hyorauiic lines, and adjusting the speed governor, a fourth start attempt vvas made at 23:!)0 hours. The unit started rorrnally and ramped to idle at 23:18 hours. The Qperator drained a high level in a seal drain pot, to clear a high level alarm, and allowed the unit to warm up for a few minutes to mitigate any vibration problems that might be encountered during acceleration of the void turbine. The unit accelerated and loaaed normaity; +laring ceased at 23:26 hours. The spa*e unit, 1801, which normally would have been started when 1802 failed to start, was unavailable. It hdd been removed from the compressor unit on June 5, to complete 2 scneduted 4,000-hour Inspection. Jim Mullins Flow Station 1 Operations Supervisor. ARCO AlaskG.

Volume flared: 150A MSCF Time on flare: 333 minutes The event occurred while servicing a PSV for the B gas train cooler. (This was a routine PM function.) In order to test a PSV in this service, the upstream block valve is closed, isolating the pressure source, and the PM conducted. Normally, the PSV is actuated, reseated and put back in service. In this case, the PSV was actuated and would not completely reseat. The failure to reseat would normally be anon-event, but in this case the upstream block valve was also leaking. After a short time, the leak rate through the closed upstream block valve and partially seated PSV caused law level flaring from the third stage HP/1P flare. Once this flaring was traced to the leaking PSV/ block valve pair, isolation procedures were initiated. Mechanics were sent to try to stop the block valve leakage by actuating the valve and then by pumping sealant into the valve body. This effort failed and the decision was made to cut rates and to isolate the entire gas train. The gas train isolation then ran into problems when one of the isolation valves would not seal off. This delay compounded the flaring event and led to a more extensive isolation of additional plant coolers. Once the final valve was isolated, the depressurization went smoothly.
