Wind turbine maintenance

The global focus on renewable energy means the wind turbine industry is growing rapidly. But how do you maintain wind turbines to ensure they function properly?

What does wind turbine maintenance involve?

Any wind turbine requires regular routine maintenance performed by professional wind turbine technicians to avoid component failures and unscheduled fault repairs.

Such planned maintenance is carried out once or twice a year and can take up to a day per wind turbine. The wind turbine technician will inspect all equipment to check if any repair is needed for the various components — these include air filters, the rotor shaft, yaw system, gearbox, electrical cabinet, and more.

Another important wind turbine maintenance task is to check and replenish oil and lubrication levels. Correct greasing is vital to lower failure probabilities, increase equipment lifetime and reduce operating costs.

All in all, planned maintenance performed by skilled wind turbine technicians is critical for any wind farm to avoid failure on components and drive down life cycle costs.

Why maintaining wind turbines is tricky

The several different types of equipment in a wind turbine mean it can be very difficult to amend component failures. Especially as the repair needs to be carried out in remote areas and spare parts for any equipment must be carried vertically several hundred feet.

Some components are relatively easy to repair or replace, but failures in the gearbox or around the wind turbine blades are very tricky to repair. Such failures usually entail significantly longer outage periods with unscheduled maintenance resulting in lost revenue.

Performing maintenance tasks is not for the faint-hearted

This makes the job of the wind turbine technician extremely important in any wind farm. These so-called grease monkeys probably have the most physically demanding job in the industry. To perform maintenance tasks they must climb up and down ladders with heavy equipment, spare parts, and grease containers in all weather conditions.

The emergence of ergonomic solutions, such as Easy Grease and the Hove Cartridge has made a huge difference in the technicians’ working environment. And with the new Hove Smart Lube, a wind turbine technician can also plan, track and document his work more easily.

Bigger wind turbines, bigger maintenance demands

Such solutions have become increasingly valuable, as both land-based and offshore wind farms are installing larger and larger wind turbines. This development places a heavy demand on performing correct turbine maintenance.

With the large components in modern wind turbines, component failure is a very cost-heavy occurrence with unscheduled stoppages and time-consuming repairs. By running preventative maintenance and ensuring correct lubrication levels based on accurate data, wind turbines can run at their highest capacity for years, driving down the operations’ maintenance costs.

    maintenance FAQ

    Wind turbine failures are hard to repair due to numerous reasons. The majority of turbines are located in remote locations, and workers face repairs up to 300 meters above ground.

    Maintenance techniques for wind turbine equipment are typically preventative actions performed at a periodic interval according to manufacturers’ specifications.

    Predictive maintenance uses data and AI to estimate the condition of wind turbine equipment and determine when maintenance is needed.

    The physical movement of the blades puts a heavy toll on all other components inside the wind turbine. A failure can occur when components aren’t adequately maintained.

    Failure of turbine components results in unplanned interruptions and costs in cranes and repairs, and revenue loss. A maintenance program helps prevent these incidents. The maintenance plan must be carefully designed to prevent unnecessary damage.
