Roughly 88% of power plants still run calendar-based maintenance as their primary strategy, even on balance-of-plant equipment where sensors are already signaling drift, heat buildup, and wear. Cooling water pumps, compressed air systems, lube oil skids, and fuel forwarding equipment rarely get the same attention as turbines and generators, yet four categories of rotating BOP assets account for the majority of unplanned generation losses when they fail without warning. OxMaint's condition-based maintenance platform extends the same predictive monitoring used on critical assets to your balance-of-plant equipment, turning sensor drift into scheduled work before it becomes a forced outage. Book a demo to map your BOP assets to a CBM strategy.

BOP Systems
Balance-of-Plant Systems and the Parameters That Predict Failure
Circulating Water System
Monitors: Pump bearing vibration, motor current, screen differential pressure
Common failures: Cavitation, fouling, bearing wear
Compressed Air System
Monitors: Discharge pressure, dew point, compressor vibration
Common failures: Valve leakage, desiccant degradation
Lube Oil System
Monitors: Oil temperature, particle count, viscosity trend
Common failures: Contamination, filter clogging, pump wear
Fuel Forwarding System
Monitors: Discharge pressure, filter differential pressure, flow rate
Common failures: Filter blockage, seal leaks
Cooling Towers
Monitors: Fan vibration, gearbox oil temperature, blade balance
Common failures: Gearbox wear, fan imbalance, basin fouling
Water Treatment Plant
Monitors: Flow rate, conductivity, membrane differential pressure
Common failures: Membrane fouling, dosing pump drift
Don't Wait for Balance-of-Plant Failures to Become Forced Outages
OxMaint extends condition-based monitoring to pumps, compressors, cooling towers, and fuel systems — not just your turbines and generators.
Asset Strategy
Asset Criticality Decision Matrix for BOP Equipment
| Asset Criticality | Example BOP Assets | Recommended Strategy | OxMaint Action |
|---|---|---|---|
| High | Boiler feed pumps, primary compressors, main cooling water pumps | Continuous condition-based monitoring | Threshold breach auto-generates a severity-ranked work order with fault classification |
| Medium | Cooling tower fans, secondary pumps, fuel forwarding skids | Condition-based with periodic inspection | Sensor trend alerts combined with scheduled inspection rounds |
| Lower | Auxiliary valves, non-critical motors, standby equipment | Preventive, time or usage based | Standard PM schedule with run-hour and usage tracking |

Industry Insight
Why Balance-of-Plant Equipment Gets Overlooked
Most maintenance programs prioritize turbines, generators, and boilers, leaving balance-of-plant equipment on fixed calendar intervals even when those assets already have sensors capable of signaling early degradation, which means usable condition data often goes unused.
Based on condition-based maintenance adoption research
Industry-reported figures place the downtime reduction from condition-based strategies at 70-75% compared to reactive approaches, a gap large enough that even partial coverage of BOP rotating equipment can meaningfully change a plant's forced outage profile.

FAQs
Frequently Asked Questions
What is condition-based maintenance and how is it different from preventive maintenance?
Preventive maintenance acts on fixed time or run-hour intervals regardless of actual equipment condition. Condition-based maintenance triggers work only when sensor data shows real degradation. Start free to see both strategies side by side.
Which balance-of-plant systems benefit most from condition-based maintenance?
Circulating water pumps, compressed air systems, lube oil skids, and cooling tower drives see the fastest returns, since their failure modes like cavitation, fouling, and bearing wear show up clearly in sensor trends well before failure.
How does OxMaint decide which BOP assets to monitor first?
OxMaint uses a criticality matrix based on consequence of failure, monitoring feasibility, and existing sensor coverage to rank assets, so the highest-impact equipment is brought under condition-based monitoring first.
Can condition-based maintenance be added without replacing our existing PM schedules?
Yes. OxMaint layers condition-based triggers on top of your existing preventive maintenance program, so lower-criticality assets keep running on schedule while high-value assets shift to sensor-driven work orders.
How quickly can OxMaint generate CBM-driven work orders for BOP equipment?
Once sensor or historian data is connected, baseline models are typically trained within a few weeks, after which threshold breaches generate work orders automatically. Book a demo to scope your BOP rollout.
