`
`Purpose
`
`This procedure outlines the steps taken by pump station persoanel in the event of the following abnormal
`operanng conditions:
`
`s Vibration alarms of vibration shatdewns occur on a Mainling Unit Gas Generator (GG), Eeaction
`Turbine (ET) or Mainline Purmp (MLP)L
`
`* The GG is operating with a high (alarm) Exhaust Gas Temperature (EGT) spread.
`¢ The GG speed (M1 s continually below 6500 rpm.
`
`Responsible and Accountable Resources
`= PEO1 O&M Supervisor
`
`¢ PEOI Control Room Operator (CRO)
`
`SPECIAL INSTRUCTIONS
`
`This procedure does not have fo be physically present af the work site, initialed, or signed.
`
`* All steps in this procedure shall be completed in sequence unless specifically noted. The CRO will
`complete the steps and direct the actions performed for this procedure.
`
`* Analarm is normally a safe but sbnormal condition and should be acted upon. The degree of haste
`used in carrying out the actions can vary with circumstances. Common sense should be applied. A
`shutdown condition is normally caused by unsafe conditions, or a condition wherein the integrity of
`the equipment is threatened. Operation of equipment under a shutdown condition is not normally
`
`alllowred.
`
`Procedure
`
`ET or Mainline Pump High Vibration
`If vibration bevels are in an alarm condition, take the following action:
`
`1. Eecord the following parameters and provide the information to Maintenance Engincening:
`* Pump drive end vertical vibration:
`* Pump drive end horizontal vibration:
`¢ Pump free end vertical vibration:
`+ Pump free end horizontal vibration:

`Inspect plenum, bellmouth, and Inlet Guide Yanes (IGV) for ice accumulation. i
`Check anti-icing equipment for proper operation, I
`Check IGV freedom of movement,
`____ Inspect compressor for foreign object damage.
`— Check freedom of rotor.
`Check magmetic chip detectors.
`
`High Vibration Shutdown on Gas Generator, RT, or Main Line Pump
`
`If nene of the checks outlined in “Gas Generator High Vibration” have been performed, due to an
`unanticipated shatdown:
`
`1. bake a physical assessment of the moechine condition,
`Inspect plenum, bellmouth, and Inlet Guide Vanes (IGV) for ice accumulation. {
`Check anfi-icing equipment for proper operation.
`_ Check IGV freedom of movemeni.
`Inspect compressor for foreign object damage.
`Check freedom of rotor.
`Check magnetic chip detectors.
`__ Pull the transition piece and mspect the turbing section on the GG.
`
`2, Ifan obvious problem is found, report the condition to Maintenance Engineering before continuing
`with this procedure,
`
`3. If the problem is not obvious, & restart may be alempled.,
`
`If the restart is successful and everything appears normal, continue operating the unit per
`
`nrmnl procedures.
`
`If the restart is successful but o vibration alarm is showing, complete the checks outlined in
`“Cins Generator High Vibration™ and report the results to Maintenance Engineering,.
`
`If a vibration shutdown occurs on the restan, contact Maintenance Engineering and do not
`attempt & second restart,

`
`The EGT spread alarm is 2754
`
`If amn EGT spread alarm 15 encountered:
`1. Read and record the temperatures from each thermocouple.

`
`— MOTE
`Do not assume that the thermocouple is open, as it may be the case that a can has flamed out. If a can has
`actually flamed out, the average EGT readings displayed by the FT-100 and the strip chart recorder should
`
`2. Ifacan is cold, immediately stop the engine and troubleshoot.
`—— HOTE
`
`Low or high is a relative term, but implies that the can is alive but burning at a high or low temperature
`relative to the other cans.
`
`5, Ifacan is low or high in temperature, change the speed of the engine and observe what happens.
`
`— 4. Iftroubleshooting does not yield a solution, contact Maintenance Engincering.
`—— MNOTE
`The current FT-100 is not programmed for an EGT spread shutdown. The desired shutdown limit is 1490°F.
`Do ot operate the engine with an EGT spread in excess of 390°F. The only exception would be for
`troubleshooting purposes, when the amount of nonning time under an EGT spread shutdown condition
`should be imited to o few minutes.
`
`Operation of GG Below 6900 rpm
`
`== NOTE
`When N1 is below 6900 rpm, the vibration alarm and shutdown limits on the GG FT-100 monitor are
`tripled.
`
`The minimum allowabls GG speed (N1) for steady state operations is 6400 mpm,
`
`The maximum allowable GG vibration during steady state operation, with M1 below 6900 rpm, is 1.5 on
`the inlet end and 2.0 on the discharge end.
`
`L. Ifthe GG is operated for an extended peried of time below §900 rpm, eperational personnel are 1o be
`observant of the GG speed and vibration levels.
`
`2, Ifthe GG vibration levels approach the maximum allowable levels specified during steady state
`operation with N1 below 6900 rpm, change operating conditions as appropriate to increase the GO
`speed andfor lower the vibrations levels, I this is not possible, take the unit off-line and contact
`Maintenance Engineering.
