ConsiderationsConsiderations::





Hardware Partitioning Considerations/Suggestions:Hardware Partitioning Considerations/Suggestions:• Must be a physical partition:Must be a physical partition:

• Each item should only be in one branch of the hierarchyEach item should only be in one branch of the hierarchy• Consider how failure data is recordedConsider how failure data is recorded• Manuals may provide logical divisions of equipment Manuals may provide logical divisions of equipment • Boundaries should be clearly identified:Boundaries should be clearly identified:

• List specific valves, terminal blocks, etc. that end one List specific valves, terminal blocks, etc. that end one system and begin anothersystem and begin another

• Boundaries should take into consideration functions of Boundaries should take into consideration functions of equipmentequipment

• General boundary statements can be usedGeneral boundary statements can be used• Be prepared to adjust boundaries:Be prepared to adjust boundaries:

• During an analysis, better partitioning may become During an analysis, better partitioning may become evident, especially when defining functions evident, especially when defining functions

• Partition one level below where the analysis will be performed:Partition one level below where the analysis will be performed: • Provides helpful information during the analysisProvides helpful information during the analysis

What level to perform RCM analysis?What level to perform RCM analysis?• System or Subsystem level is usually System or Subsystem level is usually

the best starting point the best starting point • Complexity or other factors may Complexity or other factors may

warrant a lower or higher level warrant a lower or higher level • Different levels can be used within Different levels can be used within
