Criticality & FMECA Analysis

Not every asset deserves the same attention. FMECA establishes which failures actually threaten safety, production or compliance, so that maintenance effort and capital go where the consequences are greatest instead of being spread evenly across everything.

What this covers

  • Criticality ranking — a consistent scoring framework applied across the asset base.
  • Failure mode identification — the realistic ways each asset fails in your operating environment.
  • Effects analysis — local effect, system effect and end effect for each mode.
  • Consequence categories — safety, environmental, production, and repair cost assessed separately.
  • Detectability — whether a failure gives warning, and whether current monitoring would catch it.
  • Risk prioritisation — a ranked register that drives where to spend next.
  • Spares implications — which failure modes justify holding critical spares.

What you receive

  • FMECA worksheets for the assets in scope
  • Criticality ranking with the scoring basis documented
  • Prioritised risk register
  • Recommendations on monitoring, spares and mitigation

Standards and references

Analysis follows IEC 60812 for FMEA and FMECA technique, supported by ISO 14224 for equipment taxonomy and reliability data where oil and gas assets are in scope.
