INSUS reads vibration, temperature and operating point the turbine already logs, estimates how gearbox and main-bearing wear is moving, and shows the outage window while it can still be planned. Reliability keeps the stop.
01
Gearbox and main-bearing stops dominate drivetrain downtime.
02
Condition is read from monitoring the turbine already has.
03
Advisory only. The crane and the stop stay yours to schedule.
The problem
A gearbox or main-bearing stop is rarely just a part. It is a crane, a crew, a spare and lost energy while those are found. Temperature alone is easy to dismiss because it moves with power and speed as well as with damage. By the time the turbine has tripped, the crane date is no longer a plan.
The shift
Nothing here changes the repair or trips the turbine. It changes when the reliability team can see that a gearbox or main bearing is using life faster than the calendar says.

How it works
This fits Predictive Maintenance as drivetrain decision support above SCADA, the condition-monitoring system and the CMMS. Access is read-only. It does not trip a turbine or dispatch a crane.
Connect
Connect read-only to power, rotor speed, wind speed, gearbox and main-bearing temperatures, oil pressure and filter differential where logged, vibration and oil-debris channels where a condition-monitoring system is already fitted, plus work orders, inspections and prior replacements.
Understand
A hot bearing on a high-power day is not the same event as the same temperature at low load. The model learns this turbine model's thermal and vibration behavior against power, speed and ambient, and keeps the main bearing separate from gearbox stages.
Predict
Project how the deviation is moving, using this turbine's trend and peers of the same model in the fleet. The output is a remaining-life range in operating time, not a catalog L10 and not a single date. A flat or missing vibration channel is reported as a limit, not filled in.
Advise
Show which turbines still have time for a planned stop, given forecast wind, spare lead time and crane availability you supply. Engineers decide. A serial defect, a gearbox campaign or a bearing already on order can override the estimate, and the advice should say so.
Verify
Each inspection and replacement is set against the flag that preceded it: damage found, damage missed and flags that found nothing. Those outcomes improve the model on this fleet. A failure mode with no preceding signal is recorded as a data limit, not hidden.
Getting started
For wind plants where gearbox and main-bearing stops drive crane cost and lost energy. Delivered through Predictive Maintenance as drivetrain decision support. Expert Services can help with data assessment and validation. Advisory and read-only. A plant with only a power reading is not this use case.
Related for renewables
Gearbox and main-bearing life sits beside soiling cleaning economics and curtailment capture on the same renewables portfolio.
Gearbox and main-bearing wear often stays hidden until the turbine stops and a crane is forced. This use case estimates a remaining-life range from signals the turbine already logs so a planned window can still be booked.
SCADA with power, speed and bearing or oil temperature, plus inspection and replacement history. A remaining-life estimate that is more than a temperature trend needs vibration or oil-debris data the turbine already collects. No new sensors to start.
No. Reliability engineers review the advice and decide whether to book the crane. Access to SCADA and the controller is read-only.
Possibly nothing, and discovery should establish that honestly. Where the portal shows an alarm or a temperature but not a remaining-life range tied to your crane lead time and this fleet's own replacements, that gap is the use case.

They are population and published cost context, not a forecast for your turbines and not our result. Main-bearing and gearbox stops are widely reported as high downtime contributors, and replacement cost is dominated by crane and crew as well as the part. Value is measured on your own replacements and lost energy.
Temperature without vibration is a weak remaining-life signal. Some failure modes give little warning in the channels a turbine logs. Estimates do not transfer cleanly across turbine models. Crane availability and spare lead time can override the estimate, and the advice should show that.

A back-test on replacements you have already made will show whether the signals were there, and how much of the stop was still a choice.
