risk) are given a higher priority for inspection than items that are high probability but for which failure has low consequences. This strategy allows for a rational investment of inspection resources. Objectives RBI assists a company to select cost effective and appropriate maintenance and inspection tasks and techniques, to minimize efforts and cost, to shift from a reactive to a proactive maintenance regime, to produce an auditable system, to give an agreed “operating window”, and to implement a risk management tool. The purposes of RBI include: To improve risk management results To provide a holistic, interdependent approach for managing risks To apply a strategy of doing what is needed for safeguarding integrity and improving reliability and availability of the asset by planning and executing those inspections that are needed To reduce inspections and shutdowns and provide longer run length without compromising safety or reliability To safeguard integrity To reduce the risk of failures To increase plant availability and reduce unplanned outages To provide a flexible technique able to continuously improve and adopt to changing risks To ensure inspection techniques and methods consider potential failure modes Standards International engineering standards and recommended practices outline requirements, methodologies and the implementation of RBI.
