Accurate and objective evaluation of waves and wrinkles helps blade producers building higher quality blades

8tree, a globally operating provider of 3D optical surface inspection tools, has contracted DNV to certify its latest innovation waveCHECK according to DNV’s standard for wind turbine rotor blades (DNVGL-ST-0376). The inspection tool aims to make measurement and evaluation of composite waviness much simpler and faster.

“During the past several years we have learned from stakeholders and experts in the wind industry, that waves and wrinkles in the load-carrying composite structure of wind turbine rotor blades are a critical problem”, said Erik Klaas, CTO at 8tree. “The accurate and objective evaluation of waves and wrinkles helps blade producers building higher quality blades and reduce the risk of failure during operation. As the industry’s interest in waveCHECK continues to grow, we believe that obtaining DNV certification will be an important milestone on our journey to enabling the renewable energy market.”

“With DNV, we have chosen the world’s most trusted partner in certification in the renewable energy sector”, says Johannes Georg Leib, 8tree’s Program Manager Wind. “We are very confident that DNV will find that waveCHECK conforms to DNV’s standard for Wind Turbine Rotor Blades”.

“The improvement of quality and reliability of rotor blades is an important topic in the wind industry and we are happy to see that new technologies that support wind turbine blade manufactures are entering the market,” said Ramakrishna Parasarampuram, Head of Section for Renewables Certification at DNV. “Certification of 8tree’s waveCHECK will include assessment of the system’s hardware, software as well as the scanning process itself and its boundaries.“
