Availability, reliability and maintainability (ARM), risk based inspection and criticality analysis

Availability, reliability and maintainability

Availability, Reliability and Maintainability (ARM or RAM) analysis determines the likelihood of plant failure and the time necessary to return the plant to an operational state.  This allows the operator to meet availability targets for production throughput and reliability targets for systems to have sufficient spares and maintenance personnel, and to assure ease of maintenance.

Risktec provides a comprehensive ARM service, including:

  • Reliability data collection and analysis
  • FMEA and FMECA
  • Criticality analysis
  • Reliability block diagrams (RBDs)
  • Fault tree, event tree and Monte Carlo
  • Reliability-centred maintenance (RCM)
  • Risk-based inspection (RBI)
  • Performance standards
  • Human reliability assessment

By applying ARM techniques in the early phases of the project lifecycle, Risktec identifies any shortfalls against targets and proposes practical solutions which yield significant improvements in availability, reliability and maintainability.

"Our consultants have a proven track record in the practical application of ARM techniques to manage system downtime and reliability, and assure compliance with statutory requirements, minimise process interruptions and reduce costs."
