Speaking to Windpower TV, Force Technology product manager Morgan Troedsson said technology required to check for faults in blades needed to evolve as blades become bigger.
He said the use of ultrasound technology was commonplace, with checks for weaknesses taking place in the factory.
Additionally, ultrasound is used to detect corrosion on monopiles and foundations offshore. "They are in the sea and corrosion control was neglected for a long time. Now it's a hot topic.
"We go down with scanners for a subsea inspection to monitor the corrosion on the legs or monopiles. It's becoming important to make sure that offshore turbines last a long time."
