scope:

This Standard provides a comprehensive basis for the collection of reliability and maintenance (RM) data in a standard format for equipment in all facilities and operations within the petroleum, natural gas and petrochemical industries during the operational life cycle of equipment. Annex A contains an equipment summary that this standard is meant to cover. Its objective is to enable the collection, exchange and analysis of data based on common viewpoints. It recommends a minimum amount of data that shall be collected and it focuses on the two main issues: a) Data requirements for the type of data to be collected for use in various analysis methodologies; b) Standardised data format to facilitate the exchange of reliability and maintenance data between plants, owners, manufacturers and contractors. The main areas where such data are being used are: • Reliability, e.g. failure events and failure mechanisms; • Availability/Efficiency, e.g. equipment availability, system availability, plant production availability; • Maintenance, e.g. corrective and preventive maintenance, maintenance supportability; • Safety and environment, e.g. equipment failures with adverse consequences for safety and/or environment. This Standard does not cover: • Data on (direct) cost issues; • Data from laboratory testing and manufacturing (e.g. accelerated lifetime testing); • Complete equipment data sheets (only data seen relevant for assessing the reliability performance); • Additional on-service data that an operator on individual basis may consider useful for operation and maintenance; • Methods for analysing and applying RM data. However, principles for how to calculate some basic reliability and maintenance parameters are included in the Annexes.
