Robotic Inspection and Repair System for Wind Turbine Blades

energyTestedTRL 6

Imagine a robot that can climb wind turbine blades to find and fix cracks. Instead of just looking at the surface, it uses special heat-sensing tools to see hidden damage deep inside the material. Once it finds a problem, it uses a robotic arm to weld and patch the blade, so humans don't have to dangle from ropes hundreds of feet in the air.

The business problem

What needed solving

Wind turbine maintenance currently relies on humans dangling from ropes, which is dangerous and inefficient. Furthermore, standard drone inspections only find surface cracks, missing dangerous internal defects.

The solution

What was built

A robotic deployment system featuring a combined inspection unit (thermography and shearography) and a robotic repair arm using resistance welding.

Who can put this to work

Wind Energy
enterprise
Target: Wind farm operator

If you are a wind farm operator dealing with dangerous and slow manual rope-access maintenance — this project developed a robotic system that performs both surface and subsurface repairs remotely. This removes the need for humans to work at height and reduces curing times for repairs.

Offshore Logistics
mid-size
Target: Offshore wind service provider

If you are an offshore service provider dealing with the high risk of deploying technicians to turbines at sea — this project developed a system operated from a vessel. This allows engineers to inspect and repair blades without leaving the ship.

Composite Manufacturing
enterprise
Target: Wind turbine blade manufacturer

If you are a manufacturer dealing with long curing cycles for adhesive blade repairs — this project developed a resistance welding method for joining composite components. This significantly reduces the time needed for surface treatment and curing.

Frequently asked

Quick answers

How does this reduce maintenance costs?

Based on available project data, it reduces costs by replacing dangerous human rope access with remote robotic operation and shortening repair curing cycles through resistance welding.

Is this system ready for industrial scale?

The project includes field trials on wind towers to validate the system, indicating a move toward industrial scaling, though it is currently in the development and validation phase.

Who owns the IP or licensing for the technology?

Based on available project data, the technology is developed by a consortium of 10 partners, including SMEs like Aerones, Front Technologies, and Alerion, but specific licensing terms are not provided.

How is the system integrated into existing operations?

The system is designed to be operated remotely by engineers on the ground for onshore farms or from vessels for offshore farms.

What is the timeline for deployment?

The project period runs from 2022-09-01 to 2026-05-31, suggesting that final validation and deployment readiness occur toward the end of this window.

Consortium

Who built it

The consortium is heavily industry-driven with a 70% industry ratio, consisting of 7 industrial partners and 4 SMEs. This strong commercial lean, led by end-user EDP Labelec and specialized SMEs in robotics (Aerones), inspection (Front Technologies), and AI (Alerion), suggests the project is focused on market viability rather than pure academic research.
