This International 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;
• 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 International 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.
The following main categories of data are to be collected:
1. Equipment data, e.g. equipment taxonomy, equipment attributes;
2. Failure data, e.g. failure cause, failure consequence;
3. Maintenance data, e.g. maintenance action, resources used, maintenance consequence, down time.
Clause 9 gives further details on data content and data format.
Standardisation of data collection practices facilitates the exchange of information between e.g. plants, owners, manufacturers and contractors. This International Standard establishes requirements that any in-house or commercially available RM data system shall meet when designed for RM data exchange. Examples/guidelines/
It describes data collection principles and associated terms and definitions that constitute a "reliability language" which can be useful for communicating operational experience. It defines failure modes in the normative part of this International Standard that can be used as a "Reliability thesaurus" for various quantitative as well as qualitative applications. It also describes Data quality control and assurance practices are outlined to provide guidance for the user.
