Retrofit and Replacement of Wind Turbine Components
Replacing wind turbine components can improve efficiency, address wear and tear issues and prolong the lifespan of the wind turbine asset.
This is an important element of wind turbine maintenance and requires an expert approach to removing the redundant component and lifting the new component into place, before connecting it to the wind turbine so that it can be commissioned.
Our expert teams are trained and certified to allow them to isolate the wind turbine safely and disconnect the electrics to enable the redundant wind turbine component to be removed.
We can then lift the new wind turbine component into position and make all the required connections so that the wind turbine can become operational again.


Our Wind Turbine Component Replacement Services Include:
- Planning, method statement and risk assessment for the wind turbine component replacement.
- Isolation of the wind turbine to allow component replacement to take place.
- Wind turbine component disconnection and removal.
- Lifting a new wind turbine component into position.
- Commissioning support for your wind turbine component replacement project through our partners.

Our wind turbine component replacement project experience includes retrofitting of upgrades to wind turbine components including:
- Blades
- Gearbox
- Generator
- Blade Bearings
- Main ring bearings
Replacing heavy components like generators requires precision lifting at height, which is why AIS Wind Energy operates its own in-house fleet lifting teams specialising exclusively in the wind energy sector. By utilising our wholly owned lifting equipment—specifically suited for the unique demands of wind turbine operations—we can guarantee equipment availability and the highest safety standards. Our solutions range from high-capacity mobile cranes to internal on-board systems and hydraulic gantries, all managed by LOLER-qualified ‘Appointed Persons’. These specialists draft meticulous lifting plans to mitigate ‘wind window’ risks, ensuring that even the heaviest nacelle components are lowered and raised safely in challenging weather conditions.
Yes. We provide a full logistical support package, including the transport of oversized components such as blades or gearboxes via Abnormal Load vehicles. If your replacement part arrives before the site is ready or the weather window opens, we offer secure, internal industrial storage to protect the asset from environmental degradation, ensuring it remains in “as-new” condition for installation.
