1 Introduction
Failure data for powerplants have been collected for quite some time. Statistical data are present at NRG dating back to 1976. Failure data analyses have been performed and discussed at the powerplants by KEMA ever since 1988. All this information is documented in still readily accessible databases. The 4 Dutch production companies that were operating together as Sep gathered statistics for databases in operation from 1994 on, however this stopped in 1997. NRG continues to update its databases with data gathered during projects, to be used at future projects. In the original Sep SBS databases, information about the failure or event could be filled in by the powerplants production & maintenance personnel and sent to Sep, while reports from other Sep powerplants could be read online for all parties having access to the databases.
The results of the combined efforts are that data for the analyses of power plant failures are available from 1976 on. These data are not only collected or analyzed. The data have also been extensively used, for instance to optimize the availability and maintainability of powerplants such as the combined steam and gas plant (STEG) as shown in figure 1.1. The data can readily be applied from a special database, see figure 1.2, while the original data are still accessible for further analysis.
