REDUNDANT INDICATION WHICH WILL VERIFY ALARM:
o FEED PUMP VIBRATION PANEL INDICATION.
OPERATOR ACTIONS FOR A VALID ALARM:
o IF IN ALERT, THEN CONTACT ENGINEERING FOR RECOMMENDATIONS FOR FURTHER PUMP OPERATION.
o IF IN DANGER, THEN REDUCE TURBINE LOAD UNTIL ALARM CLEARS.
IF ALARM WILL NOT CLEAR, THEN CONSIDERATION SHOULD BE GIVEN TO SHUTTING D0WN THE PUMP.
o MONITOR FEED PUMP BEARING TEMPERATURES ON PLANT COMPUTER.
