Remote monitoring
Live DCS graphics and key process parameters create a real-time operating picture.
From DCS process parameters to vibration spectra, health scores to asset records—Domex-Engine unifies field signals into one diagnostic context for proactive inspection, trend alerts, and AI-assisted diagnosis.
Live DCS graphics and key process parameters create a real-time operating picture.
Point comparisons, health scores, surge analysis, and alert history capture early baseline deviations.
OEE, energy, vibration spectra, and characteristic frequency analysis provide the engineering layer for AI decisions.
Asset records, maintenance history, alert logs, and knowledge base entries make every diagnosis traceable.
Nine modules spanning vibration, surge, energy, and maintenance decisions help crews enter the right analysis by issue type.
Imbalance, misalignment, looseness, bearing, and oil whirl—hit rates for five common root causes.
| Type | Characteristic frequency | Hit |
|---|---|---|
| Rotor imbalance | 1×RPM dominant | Low |
| Misalignment | Prominent 2× (with 1×) | High |
| Mechanical looseness | 3×–4× | Low |
| Bearing defect | High-frequency BPFO / BPFI | Low |
| Oil whirl | 0.42–0.48×RPM | None |
Prioritize coupling alignment and anchor bolt tightness.
Calculates distance from operating point to surge and control lines in real time to determine load reduction.
| Operating point X | 62.4% |
| Surge line X | 48.1% |
| Control line X | 54.0% |
| Surge margin | 14.3% |
| Control margin | 8.4% |
Recommendation: hold load; trigger reduction if control margin narrows below 5% within one hour.
Envelope spectra compared against bearing characteristic frequencies (BPFO / BPFI / BSF / FTF).
| Feature | Expected frequency | Hit |
|---|---|---|
| Outer race BPFO | 3.05×RPM | Moderate |
| Inner race BPFI | 4.95×RPM | High |
| Ball BSF | 1.98×RPM | Low |
| Cage FTF | 0.41×RPM | None |
Conclusion: early inner-race pitting likely—offline retest within 7 days and stage matching spare.
Breaks energy changes by point, duty, and time period to locate abnormal contributors.
Primary drivers: elevated inlet temperature (check cooling) + pressure ratio above design point.
Decomposes OEE decline across availability, performance, and quality.
Primary driver: performance efficiency decline, strongly linked to yesterday's surge margin narrowing—review process adjustment records.
Searches platform history, ranks by similarity, and attaches resolution records.
| Time | Point | Resolution | Duration |
|---|---|---|---|
| 2025-08-14 | 1# drive-end vibration | Coupling alignment recheck | 3.5h |
| 2025-04-02 | 3# drive-end vibration | Anchor tightening + alignment | 5.0h |
| 2024-11-19 | 2# NDE vibration | Coupling disc replacement | 12h |
Scheduled night and day-shift summaries with anomaly lists and recommendations.
Two anomalies (2# NDE vibration 2× rise + 2# elevated inlet temperature); day shift to verify.
Priority-ranked maintenance tasks with labor, parts, and owners—one-click work orders.
Cross-unit health ranking plus 7-day anomaly probability heat map.
Surfaces anomalies before morning meetings, explains causes, and packages next steps crews can execute.
After night shift, the platform auto-generates crew summaries with points to watch, trends, and recommended actions before morning meetings.
Example: 2# bearing temperature—platform reads collected data and AI-forecasts trajectory to catch baseline deviation early.
Operators ask directly; platform combines live data, alert history, and knowledge base with evidence-backed advice.
Combines health trends, similar events, spares, and windows for maintenance priority and next actions.
Consolidates risk, diagnostics, and experience so O&M moves from ad-hoc judgment to repeatable workflows.
Surfaces health scores, margins, and trends before anomalies become shutdowns.
Delivers conclusions plus spectra, history, and troubleshooting sequence in one evidence chain.
Every consultation, alert, and action becomes a retrievable event record for the next similar issue.
From site assessment and installation through remote commissioning—Domex-E engineering leads end to end to minimize customer coordination.
