CCPS Generic Failure Rate Data Base Taxonomy

CCPS Generic Failure Rate Data Base Taxonomy... 

Chapter 5—CCPS Generic Failure Rate Data Base Contains tables of generic process equipment reliability data that are structured by the CCPS Taxonomy. The data are extracted from data resources in Chapter 4. The chapter includes a discussion of the selection, treatment, and presentation of the data in the Tables. 

Section 5.4 describes the use of the CCPS Generic Failure Rate Data Base. Lastly, Section 5.5 contains tables of data in the Generic Failure Rate Data Base, organized by the numbers used to structure the CCPS Taxonomy. 

SAIC provided much of the data used in this book from its proprietary files of previously analyzed and selected information. Since these data were primarily from the nuclear power industry, a literature search and industry survey described in Chapter 4 were conducted to locate other sources of data specific to the process equipment types in the CCPS Taxonomy. Candidate data resources identified through this effort were reviewed, and the appropriate ones were selected. Applicable failure rate data were extracted from them for the CCPS Generic Failure Rate Data Base. The resources that provided failure information are listed in Table 5.1 with data reference numbers used in the data tables to show where the data originated. 

Ideally, maintenance records should be organized by a classification method compatible with the CCPS Taxonomy in Appendix A and the equipment boundaries in Section 5.5, Generic Failure Rate Data Base. It is important to remember that the taxonomy presented was developed to group equipment into classes that are differentiated by their reliability rather than their design characteristics. Records maintained in this fashion allow the analyst to more easily determine the total pieces of equipment and number failures. 

The CCPS Taxonomy developed for this book is one step toward accumulating and collating equipment reliability data for the CPI. Ideally, it will be expanded and modified as more companies make chemical process equipment failure rates and reliability data available. We expect that CCPS will update this book and the CCPS generic data base as new information becomes available. The taxonomy may also require modification where experience shows it is needed. We would appreciate any contribution from readers to these ends.
