Certification

Certification

As renewable energy technologies advance, their continued safety, reliability, and performance must be assured. As safety science experts, UL helps clients navigate these risks through certification for products, projects, and gird code compliance. The UL certification extends compliance and provides assurance and confidence in the reliability of renewable energy technology.

Wind

UL offers comprehensive certification services for wind turbines, components and systems according to international and national standards and regulations (e.g., IEC 61400 series, GL guidelines, UL 6141 and IECRE). We address customer needs by aligning our wide range of services to find a combination of solutions that most rapidly and efficiently brings their product to market.

Accreditations and Quality Agreements

UL is dedicated to technical excellence and quality across the globe. Our DAKKS accreditation is proof of our commitment to quality and competence for activities as a conformity assessment body according to ISO/IEC 17065. For the wind industry the DAKKS accreditation helps ensure that once tested, components, parts and wind energy technology are accepted everywhere making wind energy technology safe, compliant and cost effective. Certificates are available upon request or at www.dakks.de.

UL is a member of major national and international committees that are defining wind energy standards including:

  • IEC – International Electrotechnical Commission
  • IECRE – International Electrotechnical Commission Renewable Energy
  • AWEA – US National Standards Development
  • DKE – Deutsche Kommission Elektrotechnik Elektronik-Informationstechnik in DIN und VDE
  • DPInst – Committee of German Certification Bodies for Wind Turbines
  • BSH – German Federal Maritime and Hydrographic Agency
  • FGW – Federation of German Windpower and other Renewable Energies

Offshore

Compared to onshore wind farms, offshore installations are more complex in terms of structural design, installation and maintenance. Particularly those sites far away from the coast demand thorough development and planning of the turbine, its components and the entire wind farm as a solid base for the investment. Based on pioneer research work in the offshore environment and the accumulated know-how from various offshore projects, UL can help to facilitate your access to the offshore business.

Certification of Turbines or Components
The certification process of an offshore wind turbine or its components is similar to an onshore certification process. Depending on the applied guideline, additional technical requirements have to be integrated in the certification process.

Assessment of Construction and Foundation
While offshore wind turbines are usually type-certified serial products, the foundations are usually designed for the specific projects. Special focus must be given to the generation of the appropriate load assumptions for the foundations, in order to allow an adequate and cost-efficient design. UL offers assessment of construction documents and interpretation of existing rules and guidelines.

Project Certification
Project certification confirms that a specific offshore wind project complies with a set of rules and guidelines. The scope of the project certification usually includes environmental analysis and design basis, structural design, manufacturing and erection.
