BS EN 16991 is a European Standard that focuses on a risk-based inspection framework. BS EN 16991 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.
RBIF encompasses both inspection and maintenance, BS EN 16991 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.
BS EN 16991 on risk-based inspection framework is useful for:
Inspection and maintenance approaches in the 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 unscheduled downtime due to corrective maintenance, to avoid shutdown due to equipment failure and/or to reduce undesirable impacts on process safety.
BS EN 16991 provides the essential elements of risk-based assessment of industrial assets according to the approach developed and demonstrated in the European pre-standardization document CWA 15740:2008.
The BS EN 16991 is intended for managers and engineers establishing the RBIM (Risk-based Inspection and Maintenance) policies in the process, power, steel and other relevant industries. BS EN 16991 is intended to be used in conjunction with the relevant internationally accepted practices, national regulations and RBI company policies. BS EN 16991 aims to provide a common reference for formulating the RBI policies and developing the corresponding inspection and maintenance programs.
The main goal of BS EN 16991 and the former RIMAP project is to support 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.
