Onshore Renewable Asset Support – UK
Hydrafly provides drone assisted cleaning solutions for onshore wind turbines across the UK.
Our heavy lift, tethered multi-rotor system enables safe access to turbine blades and towers up to 100 metres under CAA authorisation, without the need for scaffolding or complex access equipment.
The service can be deployed as a standalone cleaning solution or as part of a wider turbine maintenance programme, working alongside O&M contractors and other access methods where required.
Services
We provide wind turbine blade and tower cleaning, de-icing application and 4K visual inspection support. Cleaning can also be deployed in preparation for inspection or repair works.
Technical Capability
Hydrafly operates a Drone Volt Hercules 20 heavy-lift UAV, configured for tethered industrial cleaning operations.
Authorised to operate up to 100 metres under CAA Operating Safety Case
Heavy-lift tethered octocopter system
High-pressure (3500 PSI) hot water cleaning
Integrated safety and recovery systems
Where Drone Cleaning Adds Value
Drone assisted turbine cleaning provides a flexible, lower intervention option within structured maintenance programmes. It can support asset operators;
Between scheduled major maintenance cycles
As preparation prior to inspection or repair works
During seasonal icing conditions
Where access mobilisation is logistically complex
- 01What height wind turbines can you clean?
Hydrafly is authorised under our CAA Operating Safety Case to operate up to 100 metres above ground level. Higher hub height deployments can be discussed subject to site access strategy and regulatory approval.
- 02What environmental controls are in place?
Hot high pressure water is prioritised wherever possible to minimise chemical use. Where additives are required, environmentally considerate products are selected in line with site and land management requirements.
- 03How long does it take to clean a turbine?
Typically 1–2 turbines per day depending on turbine height, blade condition and weather conditions.
- 04Can you operate in high winds or cold conditions?
We can operate in wind speeds up to 31mph and temperatures down to -20°C, subject to site specific risk assessment and weather monitoring.
- 05Can drone cleaning be integrated with existing maintenance teams?
Yes. The system can be deployed independently or incorporated into structured maintenance programmes alongside existing site operations.
