CMScore

Although new wind turbines often come equipped with modern condition monitoring systems, older turbines frequently need to catch up. These less efficient pioneers generate less energy while your costs rise as the turbines age.

Avoidable outages force you to make an investment decision. Should you invest in a repowering project, which depending on its scope and local permitting requirements, will take a significant amount of time, or continue operating your existing fleet? Our answer: A cost-effective retrofit with our CMScore condition monitoring system.

Calculate your payback period in three easy steps. Use our ROI calculator.

In many cases, the initial investment in CMScore pays for itself within the first year of installation. Use our ROI calculator to find out exactly when your system will start to benefit from the installation.

Here's what CMScore has to offer

CMScore is designed for condition-based maintenance of the powertrain. It enables early damage detection and predictive maintenance.

Quick payback

Many installations pay for themselves within the first year. This allows you to make a cost-effective investment and ensure the long-term operation of your existing systems.

Take advantage of over 10,000 reference projects

Reliable and field-proven analyses are based on the evaluation of measurement data from more than 10,000 wind turbines.

Centralized analysis in the WebLog Suite

Process measurement data from CMScore and third-party systems in a single, unified interface. This allows you to keep track of your entire fleet at all times.

Fast installation

In many cases, existing sensors and wiring can be reused. This reduces installation time and minimizes your plant's downtime.

Compact and lightweight

At just 2.6 kg, the CMScore is lightweight and compact. It can easily be transported and installed in your gondola without taking up much space.

Flexible and reusable

The CMScore system remains usable even when a turbine is repowered or decommissioned. The system can be removed and used in another turbine.

Trusted monitoring expertise

16,000+ monitored wind turbines
32+ turbine manufacturers
340+ offshore structures
Over 25 years of monitoring experience

Signs of wear and tear in aging fleets

As plants age, the risk to the powertrain increases. CMScore detects this damage before it threatens continued operation.

Main Bearing Damage

The main bearing supports the entire rotor load at very low speeds. Damage develops gradually over months without being noticed. If detected early, a replacement can be scheduled during a maintenance window instead of requiring an emergency crane call.

Gear tooth damage in the transmission

Pitting, micropitting, and tooth fractures are caused by continuous loading and cyclic load changes. They can be identified by characteristic gear mesh frequencies long before they become noticeable during operation.

Bearing damage in the transmission

Rolling bearings in planetary and spur gear stages typically exhibit raceway and rolling element damage. If left unnoticed, these particles can carry the damage further through the oil circulation system, ultimately leading to the need for a gearbox replacement.

Generator bearing damage

This is the most common type of damage to the drivetrain, and it can be repaired with reasonable effort as long as it is detected in time. If overlooked, however, it can spell the end of continued operation for older systems.

Imbalance and misalignment

After repairs or as wear increases, the generator and transmission are no longer precisely aligned. This results in continuously increased forces on the clutch and bearings—a cause, not a symptom.

Generator Electrical Faults

Winding faults and air gap asymmetries also produce characteristic vibration signatures. Vibration analysis detects these anomalies before they lead to generator failure.

How It works

CMScore acquires measurement data directly from the turbine and transfers it to the WebLog Suite. There, the data is processed, analyzed, and automatically converted into alarms and reports. Data from third-party systems can also be integrated, giving you a unified view of your entire fleet in a single interface.

How the data is monitored is up to you. You can perform the analysis yourself using the WebLog Suite, or rely on our DNV-certified Remote Monitoring team to monitor your assets on your behalf—including alarm management and actionable maintenance recommendations.
