A low pressure compressor at FS-3 tripped off line at 1630 hours on July 13, 1996 due to a high ten~perattue tndtcation and alarm an the T/C power supply unit This high temperatunr indication largely resulted from the high ambient temperal:ure conditions existhig that day. The turbine was cranked in an effort to rcdttcc the unit's temperature. Several attempts were made to restart the T(C unit, starting as early as 1 S minutes after initial trip. Minor adjustments were ultimately made to the louvers on the waste heat. recovery unit to facilitate and expedite the restart process. In total, six restart attempts were made prior to successful restart at 2000 hrs. By 2015 hours, the snit was fully loaded, and flaring ceased, When tlic T/C went down a prudent decision was rnadc to attempt to restart the tJnit in an expeditious a manner as possthle, thus ending the flare and minimizing the volume of ga<s ultimately flared. It. was anticipated that restart could Ue achieved in less than 30 minuses. 13y contrast, shutting in pmduction to remove the necessity for flare would have taken much longer, requiring shut in of 40 - .50°l0 of the Flow Station watcrflood production, This choice would also have required significant adjustments to gas lift and gas tranhit system operations slid would have placed other Flow Stations and Gathering Centers in significant risk of flaring while the production shut in was initiated and optiinizcd. With restart of the T/C ucut expected every 15 to 45 minutes, it appeared restart of the unit continued to be the most efficient manner of minimizing the volume of gas flared. if you have any questions or concerns, please contact me at 659-5922. .'mil --- - John A.
