Purpose of Equipment Criticality Review is to...

• Identify the relative importance of equipment and systems to an operation to determine priorities in applying risk measures that mitigate the consequences of failure or loss of equipment function
• Ensure the risks associated with equipment failure or loss of function are considered in terms of their impact on both Commercial and Integrity performance of an asset
• Consider Production interruption as a commercial impact due to the loss of equipment function
• Consider Safety of Personnel and Environment as an Integrity impact due to the failure of equipment or materials
• Ensure a balanced approach is taken when considering the commercial and Integrity aspects of equipment criticality

Value of Equipment Criticality is simply…

• Deliver clear understanding and basis to prioritize maintenance tactical measures that reduce risk exposure
• Aligns the organization in their understanding of equipment based operational risk and relative importance
• Engages the people who have relevant experience of equipment performance to share and capture their knowledge in a structured fashion
• Provide a foundation and rationale for balancing the effort, activity levels and focus on all equipment that constitutes the asset – It is not practical to apply the same maintenance tactics to all equipment
• Provide the means to decide which equipment maintenance strategy to apply – Scheduled preventive maintenance, condition based maintenance, run to break maintenance or other
• Allows prioritization of equipment procurement efforts, equipment spares and operating documentation
• Determines where additional equipment performance review such as FMEA is applied
