Nordex Delta 4K Type 1 maintenance in Ukraine

Scheduled maintenance on 9 wind turbines

The project ran from 24 November 2025 to 25 March 2026 on 9 Nordex Delta 4K turbines in Ukraine. Turbine work was completed on 21 March, followed by the final project close-out and reporting period.

The campaign totalled 69 turbine-days, averaging approximately 7.7 working days per turbine. The figure covers actual Type 1 maintenance days assigned to individual turbines and excludes travel, standby and office time.

Type 1 maintenance scope

The campaign combined scheduled maintenance activities with measurements, inspections and technical-condition records. Work followed project requirements and safety rules, while detailed technical procedures remain confidential.

• scheduled wind turbine maintenance
• laser shaft alignment of the drivetrain
• inspection and service of lubrication systems
• bolted connection inspection
• functional checks and completed-work documentation

Repeatable delivery and traceable reporting

A consistent work organisation method supported comparable inspections across all 9 turbines. Each stage was documented, with measurements and completed activities recorded in the project documentation.
