Regardless of the size of your project, Global Wind Service offers the complete package of blade services for both on and offshore wind farms. This includes everything from inspections, cleaning and painting to complex structural repairs and application of leading edge protection technologies.
As experts in blade repair and service we have participated in leading edge maintenance campaigns for many years and have built up competences with all the current protection technologies.
Our wide-ranging expertise covers all major wind turbine models and includes both retrofit work as well as scheduled service and maintenance.
We offer everything from specific services on an individual technician level, to complete service teams with project management and full-scope solutions.
For quick access and high mobility, we use rope access on low complexity projects. This method secures a more speedy process, requires less preparation and is ultimately a less costly method compared to the use of
platforms. All of our rope access works are of course carried out in accordance with IRATA guidelines and all our specialised technicians are trained accordingly.
For the more complex and time-consuming works we use platforms, which allows us to work at the same spot for a longer time and to carry with us more tools.
Like in everything else we do, our focus lies on safety, quality, flexibility and having the right people with specialised competences. Combined with our vast experience this makes us your ideal partner for blade repair and service.
Adding to this, Global Wind Service has experience working from jack-up installation vessels offshore. We can deliver full repair teams or provide you with a turnkey package solution covering the complete scope of your blade campaign.
Together with our related company, Fred. Olsen Windcarrier, we have developed a unique model for offshore blade exchange and repair directly from the vessel while

Repowering and Life Extension of wind turbines
Wind turbine repowering is the process of replacing aging, generally smaller wind turbines and turbine parts with new and more efficient units. This leads to higher capacity and more efficient turbines, significantly increasing the amount of energy generated from a given wind farm. As such, power production goes up while extending wind farm lifetime.
Repowering existing wind turbine technology is a complex process that requires the ability to blend new upgraded technology and equipment with aging machines – sometimes even of different manufacturers. Projects may include increasing the turbine tower height, installing a larger rotor, upgrading gearboxes (generators), hubs, drive trains, main bearing assembly or the whole nacelle.
Our many years of turbine installation and service of all major turbine makes and models has given us extensive knowledge about the turbines, making us the ideal partner for your repowering project.
At Global Wind Service we offer complete repowering and life extension services for all types of wind turbines.
