Collection and Exchange of Reliability and Maintenance Data for Equipment
Petroleum and natural gas industries—Collection and exchange of reliability and
maintenance data for equipment
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. It describes data-collection principles and associated terms
and definitions that constitute “reliability language” that can be useful for
communicating operational experience. The failure modes defined in the normative
part of this standard can be used as a “reliability thesaurus” for various
quantitative as well as qualitative applications. This standard also describes
data quality control and assurance practices to provide guidance for the user.
contractors. API 689 establishes requirements that any inhouse or commercially
available RM data system is required to meet when designed for RM data exchange.
Examples, guidelines and principles for the exchange and merging of such RM data
are addressed. ·
