22、2018EN 16991:2018 (E)IntroductionSince the late 1990s, inspection and maintenance approaches in industry have been globally moving from prescriptive, time-based towards risk-based ones. This trend has clearly been established by the wish to increase the on-stream production time, to reduce unschedul
23、ed downtime due to corrective maintenance, to avoid shutdown due to equipment failure and/or to reduce undesirable impacts on process safety.This European Standard provides the essential elements of risk-based assessment of industrial assets according to the approach developed and demonstrated in th
24、e European pre-standardization document CWA 15740:2008 1. The CWA 15740 document was updated in 2011, and from 2014 its further development continued within this document and the corresponding EU Project RIMAP (Risk-Based Inspection and Maintenance Procedures for European Industry) 2 3. The document
25、 is intended for managers and engineers establishing the RBIM (Risk-based Inspection and Maintenance) policies in the process, power, steel and other relevant industries. This document is intended to be used in conjunction with the relevant internationally accepted practices, national regulations an
26、d RBI company policies. The document aims to provide a common reference for formulating the RBI policies and developing the corresponding inspection and maintenance programs.The background of the RBIM methodology is provided by the EU project RIMAP (Risk-based Inspection and Maintenance Procedures f
27、or European Industry) 4. In this project, the industry independent methodology has been validated for chemical, petrochemical, power and steel industries and summarized in the respective RIMAP Application Workbooks 4.The main goal of this European Standard and the former RIMAP project is to support
28、the establishment and application of risk-based inspection and maintenance programs in industrial plants in a documented and efficient way, while at the same time maintaining or improving safety, health and environment performance. The RBIF addresses primarily static pressure equipment (e.g. tanks,
29、piping), but is also applicable to dynamic/rotating equipment (e.g. pumps, turbines, valves) and pressure relief devices, and it can be extended to other types of equipment, if appropriate. It addresses primarily the equipment and/or systems in the in-service phase of the operation, but can also be
30、applied in the design-phase for analysis and/or determination of maintenance/inspection strategies or life extension phases. Application of this RBIF in industry will take into account also the general developments in the industry and maintenance practices (e.g. The Industry 4.0).5BS EN 16991:2018EN
31、 16991:2018 (E)1 ScopeThis European Standard specifies the Risk-Based Inspection Framework (RBIF) and gives guidelines for Risk-Based Inspection and Maintenance (RBIM) in hydrocarbon and chemical process industries, power generation and other industries where RBI is applicable.Although RBIF encompas
32、ses both inspection and maintenance, this document focuses primarily on Risk-Based Inspection (RBI) and its applicability within the context of RBIM. The RBIF thereby supports optimization of operations and maintenance as well as asset integrity management.2 Normative referencesThere are no normativ
