Compressor train uptime +12% over twelve months.
Multivariate health model catches degradation hours before trip on a critical gas compressor.
What was happening before.
Trips happened with little warning. Vibration alarms tripped only after damage had already started, and bearing temps were a late indicator.
- Asset is uninstrumented for some health proxies; we use what's in the Historian.
- Cannot recommend manual operator action without an MOC sign-off.
- Maintenance windows are scarce; the model must be confident enough to justify pulling forward an outage.
What we built, on what data.
- › Historian tags: vibration RMS, bearing temp, suction/discharge P&T, lube oil ΔT, motor current
- › Maintenance log: work orders, parts, downtime hours
- › Trip log
- 01Define a healthy envelope per operating modeUsed Data Explorer to label clean steady-state runs across the past three years.
- 02Train a multivariate residual modelAnomaly score rises hours before trip; validated on three historical events.
- 03Forecast time-to-eventProject residual forward to recommend the next safe maintenance window.
- 04Hand off to maintenance planningRecommendations land directly in the planner's queue with severity and confidence.
Who uses it, and where it fits in the day.
Used by the rotating-equipment engineer daily. Maintenance planner sees recommendations in the queue. Operations notified only when severity warrants.
Quantified, with timeframe and caveats.
- R1Audited uptime +12% on the critical compressor train.
- R2MTBF +41% vs prior 12-month baseline.
- R3Three confirmed early-catch events with post-mortem sign-off.
Operational outcome (proof rule): Audited uptime on the critical compressor train improved 12% over 12 months; MTBF up 41% with three confirmed early-catch events.
"We schedule the intervention. We don't get woken up at 2am for it anymore. That's the difference."
Relevant for teams trying to…
Oil & gas teams responsible for compressors, pumps, or turbines with scarce maintenance windows.
- One healthy envelope per operating mode beats a single global model on rotating equipment.
- Wire recommendations into the planner's queue, not a separate dashboard, or they don't get acted on.
- Three confirmed early catches is enough to fund the next two years. Document them carefully.
