Reliability Centered Maintenance
RCM based on SAE JA 1011

Achievements (chemical plants):

• Up to 30 % reduction of production losses
• Up to 40 % reduction of maintenance costs
• Significant safety improvements (including environment)

Reliability Centered Maintenance (RCM) allows to formulate recommendations on maintenance. RCM is a systematic and structured approach and gives answers on following questions:

• Which maintenance approach should be applied
  (safety, environment, operation)
• What are the reasons for the implemented maintenance strategy
• Is there a way to reduce maintenance costs
• Is the selected maintenance strategy cost effective or should it be redesigned

The seven RCM questions (SAE JA 1011):

• What are the functions and associated desired standards of performance of the asset in its present operating context (functions) ?
• In what ways can it fail to fulfil its functions (functional failures) ?
• What causes each functional failure (failure modes) ?
• What happens when each failure occurs (failure effects) ?
• In what way does each failure matter (failure consequences) ?
• What should be done to predict or prevent each failure (proactive tasks and tasks intervals) ?
• What should be done if no suitable proactive task cannot be found (default actions) ?
