According to analized the turbine and diesel plant reliability, we were able to picked up some problems to make large amount of Failure Rate or Manning Index.<BR>1) Mainly trouble of auxiliary equipment caused by low grade fuel. The most affected equipment is the fuel purifier and also following equipment affected too, <BR>Diesel Plant: LO purifier, Auxiliary boiler, DIG, M/E, FO filter LO filter, Incinerator. Turbine Plant: Main boiler burning equip.<BR>2) Automatic equipment failures occurred 18 days each and need 8.5 MH. MI and FR are occupied approximately 1/3 of whole plant. These are judged ghost & unknowm reason that is about 50 to 70%.<BR>3) Turbine plant are needed much recovery time to maintenance for cooling down the steam line, move the big mass of heavy weight and valve operate for complex construction. Mainly cause are aging, defective fitting and poor materials.<BR>So, we should make some counter plan to reduce the Failure Rate and Mannind Index as follows.<BR>a) To be developed fully automatic treatment system of fuel and waist oil (FWTS) to reduce a failure ratio of fuel and LO purifier, auxiliary boiler, etc.<BR>b) To be developed Total Distributed Control System (TDCS) with back up controller to increasing continuous running of control equipment and quickly recoverling.<BR>c) To be set the central fresh water cooling system (CCFW) to reduced a pipe corrosion and Maintenance man hours.
