UL Solutions provides a wide number of testing, inspection and certification services for new and aging onshore and offshore wind farm projects.
Our work includes many facets, including performance and mechanical load testing, grid code compliance, project certification and lifetime extension. We can help you on your journey toward energy transition.
Focus on offshore wind farms
Compared to onshore wind farms, offshore installations remain more complex in terms of structural design, installation and maintenance. For sites built farther from the coast, the entire wind farm, as well as its turbines and components, must go through thorough development and evaluation to demonstrate that they are a worthwhile investment.
UL Solutions has pioneered research in the offshore environment, and our organization has gathered knowledge and expertise from various offshore projects. The certification process for offshore wind turbines and components is similar to the certification process for onshore installations. However, the process may require integrating additional technical criteria similar to those found in the testing and certification process.
Relatedly, the foundations for offshore turbines are often designed for specific projects. UL Solutions offers assessment services for construction documents and can help you interpret existing rules and guidelines so you can establish an effective, cost-efficient design.
Offshore Wind Energy Services
Providing independent technical advisory, software, certification, testing and inspection services to the offshore wind energy industry.
Accreditations and participation in technical committees
UL Solutions is dedicated to technical excellence and quality across the globe. Our DAkkS accreditation (Accreditation Certificate D-ZE-11326-01-00 according to DIN EN ISO/IEC 17065:2013) is proof of our commitment to quality and competence for such activities as creating a conformity assessment body according to internationally harmonized standards. Within the wind industry, the DAkkS accreditation helps facilitate the acceptance of tested components, parts and wind energy technology and supports safer, compliant and cost-effective wind farms.
UL Solutions actively participates in major national and international committees and working groups that are defining wind energy standards including:
- International Electrotechnical Commission (IEC)
- International Electrotechnical Commission Renewable Energy (IECRE)
- American Wind Energy Association (AWEA) – U.S. National Standards Development
- German Commission for Electrotechnical, Electronic, and Information Technologies (DKE)
- DPInst – Committee of German Certification Bodies for Wind Turbines
- Federal Maritime and Hydrographic Agency of Germany (BSH)
- Federation of German Windpower and Other Renewable Energies (FGW)
