The PERD Project is now managed by Reliability Dynamics. For information, please contact Tony Ciliberti at perd@aiche.org.
The CCPS PERD Project’s mission was to help processing and manufacturing industries minimize hazards and improve equipment availability with high-quality equipment reliability and maintenance data. This mission remains the same now that Reliability Dynamics is managing the project.
PERD design principals are to simplify, standardize and automate equipment reliability data processes. PERD methods are compliant with Industry Standard ISO 14224. The ISO 14224 standard gives CPI and HPI a roadmap for digitalization: a logical and standard manner for representing facilities; standard definitions for equipment; and standard failure data collection, merging, and assessment processes.
High-quality, structured data give companies better insight into equipment reliability and performance and thus enable data-driven decision making for equipment assets. High-quality data also support quantitative risk assessment (QRA). With PERD methods, participating companies can use high-quality data to quickly identify equipment failure events with the greatest consequences. They can analyze those failure events to identify failure patterns of the equipment causing them and obtain details necessary to take corrective action. They can then resolve the reliability issues by implementing corrective maintenance measures.
The Center for Chemical Process Safety has been providing quantitative risk assessment data to the chemical process industries since the 1980s and published the first of its “CCPS Guidelines for Process Equipment Reliability Data” in 1989 and “Guidelines for Improving Plant Reliability through Data Collection and Analysis” in 1998. Subsequent enhancements to this information-collection effort led to PERD, which provided deeper and more specific analyses of equipment availability, reliability, design improvements, maintenance strategies, and life cycle cost determination.
The PERD software component has been phased out as a CCPS product and now managed by Tony Ciliberti of Reliability Dynamics, on a personal basis. The original PERD taxonomy and publications are still available for purchase. For taxonomy and data book purchases, please contact ccps@aiche.org.
