Safeguarding sustainable offshore wind investments.
Offshore wind installations are more complex than onshore wind parks in terms of structural design, installation of the turbine and maintenance. Sites far from the coast demand thorough planning for each stage of the project.
With over 25 years of offshore research and industry knowledge, UL can help you evaluate your turbine and its components. UL has performed research into incoming wind and wake of turbine, water pressure rings, wave loads, and acoustics and operational noise, all of which impact performance of an offshore turbine.
When developing new wind turbines, extensive measurements of the mechanical loads acting on the prototypes during operation are indispensable. The results of these load measurements are used in the design validation and certification of wind turbine prototypes. Design validation and certification represent the key to a mechanically reliable wind turbine that is ready for series production.
In addition, UL offers online load monitoring of wind turbines and their components. As a cost-effective alternative to IEC-type load measurements, this is particularly suitable for determining local strains or stresses in the material, and enables a direct comparison that can be made between the site-related loads and data simulated in the design development by extrapolating the measured data.
UL is accredited to EN 45011 for certification of offshore wind turbines and offshore wind farms, and is currently performing measurement (loads, noise and power curve) and R&D Services from our dedicated offshore wind office in Hamburg, Germany.
