Wind turbines

Maintaining wind turbines along with their associated installations in proper condition is a significant challenge. The primary goal of wind turbine maintenance is to extend its operational uptime between planned shutdowns and minimize the risk of failures.

As a company with extensive experience in repairs, we can offer a range of services related to wind turbine maintenance.

Disassembly

Non-destructive testing

Non-destructive testing allows for the detection of all types of defects and cracks, which can be very dangerous for the equipment. A broken piece can cause cascading damage throughout the entire gearbox area.

The non-destructive testing (NDT) methods we use include:

Visual inspection
Magnetic particle testing
Penetrant testing
Ultrasonic testing
Radiographic testing
Endoscopic testing

Destructive testing

Measurements

Measurements of wind turbine components include:

Measurements of body geometry (flatness, perpendicularity, concentricity, etc.) using the Leica Tracker measurement system
Measurements of bearing housing sockets – using micrometers
Measurements of runout – using dial indicators

Technical condition assessment

Re-engineering of defective components

Replacement of standardized components

The wind turbine also contains various standardized components, such as gaskets, rings, seals, screws, washers, nuts, etc. However, the main and most important standardized components are bearings. Through collaboration with leading bearing manufacturers, we are able to select and replace them with new ones accordingly.

Assembly

Comprehensive assembly includes:

Steam cleaning of all parts directly before assembly
Degreasing the meshing of teeth
Securing screws with adhesive to prevent loosening due to vibrational nature of operation
Tightening screws to the appropriate torque
Ensuring proper bearing clearances
Bearing assembly while adhering to temperature regime guidelines

Disassembly

Disassembly of the wind turbine gearbox is commonly employed to conduct a comprehensive diagnosis of its components and determine the cause of its stoppage or failure.

The non-destructive testing (NDT) methods we use include:

Visual inspection
Magnetic particle testing
Penetrant testing
Ultrasonic testing
Radiographic testing
Endoscopic testing

Destructive testing is carried out on those gearbox components that have been disqualified due to poor technical condition. We perform these tests to determine the cause of failure. For example, metallographic examinations of broken tooth fragments are conducted as part of this process.
