An operation monitoring unitfor acquiring process data from sensorsinstalled to a gas turbine and operation information of the gas turbine; communication unitsfor transmitting each of said two kinds of data on the gas turbine acquired in the operation monitoring unit; an analysis serverwhich calculates values of equivalent operating time using each of the two kinds of data obtained through the communication units, the value of equivalent operating time evaluating a degree of damage of a diagnosed position for each of a plurality of degradation-and-damage modes, and calculates a value of whole equivalent operating time by adding the values of equivalent operating time for the individual degradation-and-damage modes; and a facility management unitclient-server systemized using the analysis serverand a WWW browseror WWW serverare provided. By acquiring the above-described two kinds of data relating to the gas turbine during operating the gas turbine into the analysis serverthrough the communication units, a highly accurate analysis result of damage condition can be speedy obtained from values of equivalent operating time for a plurality of degradation-and-damage modes. Further, it is also possible to provide convenience that a person in a remote site can speedy and easily view the analysis results using the WWW browserthrough the client server system.
