Equipment criticality analysis
Know which assets can stop production, and which can run to failure.
If every asset is treated as important, none of them are. Maintenance effort spreads evenly across the plant while the few assets that can shut you down get the same attention as a toilet extract fan. We help operators rate every asset by the consequence of its failure through a structured criticality analysis, so maintenance, spares and engineering time follow the risk.
How we
do it.
System by system, from your own documents
Criticality done from a spreadsheet of tag numbers misses how assets work together. We assess one system at a time from P&IDs, O&M manuals and CMMS data. Engineers then check every tag against the drawings, so nothing is rated in isolation.
Consequence rated C1 to C3
Vague high, medium and low ratings get argued about and then ignored. We rate each asset C1 to C3 against safety, environment and production consequence in a criticality analysis that draws on NORSOK Z-008, ISO 14224 and ISO 31000, with redundancy taken into account. Every rating has a written reason you can defend at audit.
Workshops with the people who run the plant
A rating your operators disagree with will not survive the first breakdown. We test the draft ratings in short workshops with operations and maintenance, so the final register reflects how the plant actually runs.
Loaded into your CMMS
A criticality register that lives in a report changes nothing. We load the ratings into your CMMS so they drive work order priority, PM strategy and spares decisions from day one.
What you get.
- Criticality register, every asset rated C1 to C3 with rationale
- Consequence matrix agreed with your team
- CMMS-ready upload file
- Shortlist of C1 assets recommended for FMECA
Common
questions.
What is equipment criticality?
A ranking of assets by the consequence of their failure on safety, environment and production. It decides where maintenance effort and spares spend go first.
What does C1, C2 and C3 mean?
C1 assets have the most severe consequence of failure, C3 the least.
Which standards does your criticality analysis follow?
It draws on NORSOK Z-008 for consequence classification, ISO 14224 for reliability and maintenance data, and ISO 31000 for risk management. We adapt them to your plant rather than applying any one standard rigidly.
How often should criticality be reviewed?
After any significant plant change, and as a rule every few years.
