The Becht Equipment Reliability Planning (ERP) Work Process was designed to comply with the risk based inspection program as described in API RP-580 - Risk Based Inspection. It also complies with the ASME PCC-3 Inspection Planning Document. In addition, terminology and data are to a large extent consistent with API RP-571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry, and API RP-581, Base Resource Document-Risk Based Inspection.
Risk-Based Equipment Reliability Planning programs are an important component of total life cycle analysis for facilities. In addition, appropriate use of risk-based decision making during the design and construction phases of a project, as well as for short term maintenance decisions (e.g. repair of a pump on an emergency basis or rely on the running spare for a few days) is also very important for integrity management. These decisions are facilitated by appropriate benefit/cost analyses that are used in all phases.
The resulting inspection and maintenance plan for each item can be tabulated and sorted both by decreasing benefit to cost ratio, and S/H/E risk levels. This allows task prioritization and enables the client to get the highest return on inspection and maintenance costs. A graphical summary of an ERP assessment sorted by decreasing benefit to cost ratio is shown below.
