A modern gas turbine carries a nameplate lifespan of 25–40 years and a replacement cost of $8M–$80M depending on class. What happens between the commissioning signature and the decommissioning order determines whether that asset delivers its full economic potential — or costs 30–50% more than it should while delivering 15–20% less than it could. The maintenance history recorded in year 3 influences the overhaul scope in year 12. The overhaul decisions in year 12 determine the remaining useful life projection in year 22. And the lifecycle cost analysis in year 22 tells you whether a refurbishment at year 25 is financially rational or whether capital is better deployed on a replacement unit. OxMaint's turbine lifecycle management platform tracks every event, decision, and data point across that entire arc — so that every decision your team makes is informed by the complete asset history, not just last month's work orders.

The Complete Turbine Lifecycle: Six Stages, One Platform
Every turbine moves through six distinct lifecycle stages. Each stage generates critical data — commissioning baselines, routine maintenance records, degradation trends, overhaul findings, and end-of-life assessments. When these records live in separate systems, on paper logs, or in the memories of technicians who left three years ago, the next decision is made partially blind. OxMaint captures every stage's data in a single, continuously accessible turbine record. Talk to our lifecycle specialists to see how the platform maps to your current fleet documentation state.
Stage 01
Installation & Commissioning
OxMaint captures commissioning test results, baseline vibration signatures, thermal performance curves, alignment records, and OEM acceptance criteria as the permanent reference baseline for all future health comparisons.

The Major Overhaul Intelligence Gap: Where Most Plants Lose the Most Money
Major overhauls — typically every 24,000–32,000 equivalent operating hours for gas turbines — represent the single largest planned maintenance expenditure in a turbine's life, ranging from $2M to $18M depending on turbine class and findings. Yet most plants walk into these events with minimal advance preparation, then spend 40–60% of the overhaul duration reacting to findings they could have predicted from their own maintenance data. OxMaint closes that gap by making overhaul planning an evidence-driven process.
Without OxMaint Lifecycle Tracking
6 Months Before Overhaul
Generic scope based on OEM hour-based recommendations. No insight into which components are actually degraded. Parts ordered based on previous overhaul lists, not current condition.
During Overhaul
Surprise findings on 3–5 components requiring expedited parts. 8–14 day average schedule overrun. Emergency engineering consultations. Contractor standby time during parts wait.
After Overhaul
New baseline lost in paper records or disconnected SCADA. Findings not linked to future maintenance triggers. Next overhaul scope still starts from OEM generics.
Avg cost overrun: 28–42% above budget
With OxMaint Lifecycle Intelligence
6 Months Before Overhaul
Scope built from 3–12 years of maintenance history and condition data. RUL estimates identify exactly which components need replacement. Parts pre-ordered 14–20 weeks ahead based on predictive findings.
During Overhaul
Actual findings compared in real time against predicted condition. 92% of required parts already on-site. Average schedule adherence within 2 days of plan. No standby costs from parts delays.
After Overhaul
Post-overhaul performance reset captured as new baseline. All findings automatically linked to future maintenance triggers and next overhaul scope model. Continuous lifecycle record updated.
Cost overrun reduced to under 8% · Duration 22% shorter
Lifecycle Cost Visibility: What OxMaint Tracks Across Every Turbine Year
The most important financial question in turbine fleet management is not "what did this turbine cost to maintain last year?" It is "what has this turbine cost across its entire life, what will it cost over the next five years, and at what point does the lifecycle cost curve of continued operation cross the replacement threshold?" OxMaint's lifecycle cost intelligence module makes that analysis available on demand for every turbine in your fleet.

Every Turbine Decision Gets Better When It Is Built on Complete Lifecycle Data
OxMaint starts building your turbine's permanent lifecycle record from day one — and every maintenance event, inspection finding, and performance trend that follows makes the next decision smarter than the last.
Turbine Fleet Management: Multi-Unit Lifecycle Visibility
A power plant operating four turbines does not have four independent maintenance problems — it has a fleet management challenge where lifecycle stages, overhaul windows, and capital replacement timings need to be coordinated across units to optimize generation availability and capital deployment. OxMaint's fleet view overlays every turbine's lifecycle position, health trend, and upcoming milestone on a single planning canvas.

Frequently Asked Questions
How does OxMaint handle turbines with incomplete historical maintenance records?
Most turbines that onboard to OxMaint have gaps in their historical records — paper logs, lost files, or maintenance performed under previous ownership. OxMaint handles this through a structured onboarding process that captures whatever historical data exists, uses condition-based assessment at onboarding to establish a current-state health baseline, and then begins building the forward record from day one. For missing historical context, the platform's AI models weight recent condition data more heavily than historical trends until sufficient record depth is established, typically within 12–18 months. The system clearly flags where historical data gaps affect confidence levels in lifecycle projections so your team can make informed decisions.

Can OxMaint manage lifecycle records for both gas and steam turbines simultaneously?
Yes. OxMaint supports gas turbines (heavy-frame and aeroderivative), steam turbines, and combined cycle units within the same fleet view. Each turbine class has distinct lifecycle parameters — gas turbines are tracked against equivalent operating hours (EOH) and equivalent starts, while steam turbines use service hours, thermal cycling counts, and material life fraction calculations. The lifecycle stage boundaries, overhaul trigger thresholds, and failure mode libraries are configured per turbine class, while the dashboard, work order system, and reporting structure are unified across all types. You manage a mixed gas and steam fleet from one platform without configuring separate tools for each technology.
How far in advance can OxMaint project overhaul needs and capital expenditure requirements?
OxMaint's lifecycle forecasting module produces overhaul milestone projections at 12, 24, 36, and 60-month horizons with confidence intervals that tighten as the event approaches. At 60 months, projections use statistical degradation models and historical EOH accumulation rates — sufficient for budget planning and procurement lead-time management. At 12 months, projections incorporate live condition data, actual EOH accumulation, and component-level RUL estimates — sufficient for scope definition and parts pre-ordering. Capital expenditure forecasts are aggregated across the fleet and presented in a planning dashboard that shows monthly cash flow requirements, helping your finance team align CapEx planning with plant budget cycles.

What does the decommissioning documentation package include and how is it generated?
OxMaint generates a complete decommissioning package from the turbine's full lifecycle record with a single report export. The package includes: a chronological maintenance and inspection history spanning the full operational life, component-level condition assessments at decommissioning (supporting salvage value or secondary market transactions), accumulated operating hours and starts against design life limits, environmental compliance records for all relevant inspection periods, and regulatory documentation meeting NERC, FERC, or applicable regional compliance frameworks. For turbines being transferred to secondary markets or parts harvesting programs, the documented condition history significantly increases component recoverable value by providing buyers with verifiable service records that most decommissioned turbines lack.
