    FAQs - Drone Based High Pressure Washing for Wind Turbines

    The cleaning frequency depends on environmental factors like dust levels and salt exposure. In agricultural or desert regions, cleaning every 3–4 months is recommended, while coastal turbines may need cleaning more frequently, possibly every 1–2 months to address salt buildup.

    No, for safety reasons, turbines must be shut down and blades must be feathered to a 0° pitch before cleaning. The cleaning process is coordinated to occur during scheduled turbine downtime to avoid disrupting power generation.

    Yes, the drone is specifically designed to clean turbines in coastal and nearshore areas where salt spray and marine fouling are common. It’s more effective in these conditions compared to traditional boat-based cleaning methods, which can be cumbersome and inefficient.

    Absolutely. The drone is designed to operate in off-grid, remote locations. It has a lightweight, durable design, and uses quick-swap water and battery modules to ensure minimal downtime, making it ideal for hard-to-reach wind farms where other cleaning methods might not be feasible.

    The drone utilizes AI-powered flight path planning to adjust pressure and spray angles based on environmental conditions like wind speed, moisture levels, and debris types. This ensures optimal cleaning while minimizing water usage and preventing damage to turbine blades.

    The system is suitable for a wide range of turbines, including utility-scale turbines in both onshore and offshore wind farms, as well as smaller turbines located in urban rooftop settings or industrial zones where traditional methods are not ideal.
