Geothermal brines carry dissolved silica, calcium carbonate, and hydrogen sulfide at temperatures and pressures that attack well casings, turbine blades, heat exchangers, and pipelines simultaneously — and a plant operating without condition-based CMMS tracking for its brine chemistry, scaling rates, and well integrity is running blind in one of the most chemically hostile environments in renewable energy.

Geothermal Power Plant Maintenance Software & Best Practices
Geothermal plants can sustain 90–98% availability — but only when scaling, corrosion, well integrity, and turbine degradation are tracked continuously. Most plants lose capacity silently, without a single alarm, because there is no system connecting brine chemistry data to maintenance work orders.

The Maintenance Threat Landscape
Four Active Threats That Degrade Geothermal Assets Around the Clock
Unlike solar or wind, geothermal maintenance is not about inspecting static components on a schedule. The resource itself — the brine — is constantly attacking your infrastructure. These four processes never stop between maintenance windows.
Silica & Carbonate Scaling
5mm deposit = 20% more friction loss in a 200mm production pipeline
Scale builds inside pipelines, separators, heat exchangers, and injection lines. It reduces internal diameter, increases pressure drop, cuts mass flow to the turbine, and eventually causes flow blockages that require expensive cleaning or pipe replacement. Without periodic scale thickness measurements and chemistry tracking, you only discover the problem after output has already dropped.
Track in Oxmaint: Scale thickness logs, brine chemistry intervals, separator inspection records, cleaning work orders
Corrosion & Material Degradation
Chlorides, H₂S, carbonic acid attack steel surfaces continuously
Geothermal fluids contain chlorine, hydrogen sulfide, sulfuric acid, and heavy metals that drive uniform corrosion, pitting, and stress corrosion cracking across well casings, turbine flow paths, heat exchangers, and control panel enclosures. Corrosion coupon programs require systematic data capture — not periodic sampling that lives in a lab notebook nobody can find during an audit.
Track in Oxmaint: Corrosion coupon readings, wall thickness measurements, coating inspection records, component replacement history
H₂S Exposure & Safety Compliance
OSHA 8-hr TWA limit: 10 ppm — geothermal sites routinely approach this
Hydrogen sulfide is present wherever geothermal fluid is handled — wellheads, separator stations, turbine buildings, and injection pump areas. Every H₂S alarm must create a documented safety event record, not just sound a siren. OSHA compliance requires a full audit trail of exposure events, equipment checks, and corrective actions — impossible to reconstruct from paper logs weeks after the fact.
Track in Oxmaint: H₂S alarm events, sensor calibration records, PPE inspection logs, safety incident work orders
Turbine Blade Erosion & Fouling
Brine carryover and pH spikes can erode conventional blade materials rapidly
Flash steam turbines face blade erosion and scaling from brine carryover. ORC turbines face working fluid degradation and heat exchanger fouling. Dry steam turbines face particle impingement and NCG-driven corrosion. Each turbine type needs its own condition-monitoring protocol — and that protocol is worthless without a CMMS linking inspection results to maintenance actions and trending over time.
Track in Oxmaint: Vibration spectrum logs, blade inspection records, steam path erosion assessments, bearing clearance measurements
These Four Threats Are Active Right Now at Your Plant
Oxmaint connects brine chemistry data, sensor feeds, corrosion coupon readings, and inspection records into a single maintenance platform — automatically generating work orders the moment a threshold is crossed. No manual triage. No data stuck in a lab notebook.

Common Questions
Questions Geothermal O&M Teams Ask Before Getting Started
How does Oxmaint handle maintenance tracking for both flash steam and binary ORC geothermal plants?
Oxmaint supports multiple asset types and PM trigger logic within the same platform — flash steam turbines use runtime-hour and steam quality triggers, while binary ORC systems use heat exchanger fouling thresholds and working fluid sampling intervals. Each technology gets its own maintenance protocol inside the same unified CMMS. Book a demo to configure your specific plant technology type with our team.
Can Oxmaint connect to our brine chemistry lab system or SCADA for automatic data entry?
Yes. Oxmaint connects to existing SCADA systems, lab information management systems (LIMS), and sensor networks via standard APIs. Chemistry readings can flow directly into asset condition records, triggering work orders automatically when silica saturation or H₂S levels cross configured thresholds — no manual data transfer required. Start a free trial and test the data integration from your first week of operation.
How does Oxmaint support OSHA H₂S compliance documentation at geothermal sites?
Every H₂S alarm event creates a timestamped safety record in Oxmaint — linked to the specific sensor location asset, the personnel notified, and any corrective work order raised. These records are exportable instantly for OSHA inspections without manual reconstruction from alarm logs or paper safety sheets. Book a demo to see the full H₂S compliance documentation workflow.
Our wellfield has 20+ production and injection wells across a large area. Can Oxmaint manage this at scale?
Oxmaint's asset hierarchy is built for large distributed infrastructure — each well is a discrete asset with its own inspection history, PM schedule, and condition record. Portfolio dashboards show the health status of every well simultaneously, and mobile offline capability means field technicians can log wellpad data without connectivity. Start free and build your wellfield asset registry — most teams have all wells loaded within a single day.
How long before Oxmaint gives us meaningful trending data on our geothermal assets?
For high-frequency measurements like brine chemistry and H₂S readings, meaningful trends emerge within 30–60 days. For longer-cycle assets like turbines and well casings, you can backfill historical inspection records to build baseline condition data from day one — so trending starts immediately, not after years of fresh data collection. Start free today — your first trending data will be visible within your first month of use.
