Comprehensive Wind Turbine Service
We offer a full range of wind turbine service – from scheduled maintenance, through mechanical, electrical and hydraulic repairs, to specialist drivetrain component replacements. All work is performed in accordance with OEM documentation and safety procedures.
Scheduled turbine and infrastructure maintenance
We perform wind turbine service inspections on annual, semi-annual and other cycles according to OEM maintenance schedules or operator requirements.
Scope of inspections:
• Gearbox and generator inspection
• Electrical installation review
• Hydraulic and brake system checks
• Safety system verification
• Technical documentation with recommendations
We perform electrical inspections of substations serving wind farms and associated energy infrastructure.
Scope of inspections:
• MV and HV equipment – condition assessment, connection checks
• Protection and switching equipment
• Auxiliary circuits and controls
• Electrical measurements
• Audit-ready documentation
Mechanical and hydraulic component repairs and replacements
We perform mechanical component repairs and replacements on wind turbines, both scheduled and emergency.
Scope of work:
• Drivetrain components – gearboxes, shafts, couplings
• Bearings and rolling elements
• Brake systems – service and repairs
• Nacelle and tower structural elements
• Required assembly tolerances maintained
We provide hydraulic system service for wind turbines, critical for safety and stable operation.
Scope of work:
• Cylinders and hydraulic valves
• Hydraulic pumps – service and replacements
• Hydraulic accumulators
• Brake systems
• Diagnostics – pressure drops, leaks, wear assessment
Measurements, repairs and electrical component replacements
We perform electrical circuit measurements in wind turbines and associated infrastructure, including nacelles, towers and substations.
Scope of measurements:
• Insulation resistance measurements
• Circuit continuity and connection measurements
• Protection system measurements
• Substation measurements – MV and HV installations
• Audit-ready measurement documentation
We perform electrical equipment component repairs and replacements on wind turbines responsible for power, control and communication.
Scope of work:
• Control cabinets and switchgear
• Protection and switching equipment
• Cabling and electrical connections
• Control and communication elements
• Electrical system fault diagnostics
Specialist drivetrain work
We have particularly extensive experience in specialist drivetrain work on wind turbines. These are operations requiring precision, design knowledge and strict adherence to OEM procedures.
We perform generator and HSS (High Speed Shaft) bearing replacements on wind turbines from various manufacturers and generations.
This is work of critical importance for drivetrain reliability.
Indications for replacement:
• Increased vibration levels
• Elevated operating temperatures
• Abnormal CMS readings
• Mechanical noise
We perform replacements on: Vestas, Siemens Gamesa, GE, Enercon, Senvion (Repower), Vensys, Fuhrländer
We perform specialist gearbox bushing replacements on Vestas V112–V150 series wind turbines.
This work requires excellent knowledge of planetary gearbox design and OEM procedures.
Models covered:
V112, V117, V126, V136, V150
Assembly tolerances:
• Radial clearance: 0.05–0.12 mm
• Axial clearance: max. 0.08 mm
• Surface roughness: Ra ≤ 0.8 μm
