Blades, hub, tower and nacelle in a single intervention, in one day per machine, with nobody climbing the turbine.
With rope access, a full clean takes four to five days per turbine: rigging, abseiling from the nacelle, section by section coverage, then de-rigging. The machine is down for most of that week.
Eolinet delivers the same scope with drones flown from the ground by accredited pilots. The whole crew stays on the ground throughout. On site that means one day per turbine and downtime measured in hours rather than days.
What the full scope covers
Blades and hub, the complete tower shaft and the outer nacelle housing, in the same visit. We work with water, pressure equipment, compressors and degreasers, with the turbine held in maintenance position.
Visual inspection is part of the same flight. Every machine is handed over with its own before and after photographic report, included in the service rather than sold as an extra.
What we need from the site
Two things, both under your control: the turbine held in maintenance position (yaw and pitch) for the duration of the intervention, and preventive sealing of the nacelle before we start. Everything else is ours, aviation permits included.
How a cleaning campaign runs
You send us three facts: number of turbines, location and rotor diameter. We return a fixed quote per machine and scope. Once the order is confirmed, we file the aviation paperwork with the Spanish authority (AESA), which takes around 3 weeks.
On site, the crew arrives with the drone, pressure unit and generator, holds a toolbox talk, sets an exclusion zone and cleans one turbine per working day. Each machine is handed over with its before and after photographs, and the campaign closes with a report for your maintenance records.
Where we work
At wind farms across Spain, on nacelles up to 100 metres, with campaigns from 4 turbines. Portugal and the rest of Europe are assessed case by case.
We work for wind farm owners, O&M service providers and turbine manufacturers. For manufacturers and service providers we can deliver the scope inside your service agreement with the owner: see cleaning for OEMs.
Safety and supplier qualification
Removing work at height takes out the biggest risk of the job. The rest is covered by a documented HSE system: risk assessment, method statement, field forms and a file for every pilot, ready for your contractor coordination platform. Details in HSE and supplier qualification.
When the full scope makes sense
When the machine is coming down anyway and the window is worth using. Also when the turbine has gone years without an intervention and the soiling is not confined to one area. If you only need blades, tower or nacelle, each scope is available on its own.
Tower and nacelle cleaning on the same turbine, before and after the intervention, with the same crop on both photographs. The blades were not part of this campaign. What is still visible is the most ingrained grime: getting one hundred per cent of it off a surface that has spent years outdoors is not possible, and we would rather show the real result than a retouched photograph.
Questions about this service
What exactly does the full clean cover?
Blades, hub, tower and nacelle in the same intervention, with before and after photographic evidence for every machine.
Can we clean only part of the turbine?
Yes. Blade and hub cleaning, tower cleaning and nacelle cleaning are separate services and are quoted independently.
How long is the turbine down?
One day. The turbine has to be in maintenance position for the duration of the intervention, against four to five days with rope access.
What do you need to send a quote?
Number of turbines, location of the wind farm and rotor diameter. With those three facts we return a fixed price per machine and scope.
Do you work outside Spain?
We operate across Spain and assess campaigns in Portugal and the rest of Europe case by case, depending on the number of turbines and the aviation rules of each country.

Three data points are enough: number of turbines, location and rotor diameter. We come back with a fixed price per machine and scope within two working days.
