Design Assessment Of Wind Turbine Foundations

Design Assessment Of Wind Turbine Foundations

Based on IEC 61400 series: the IEC international standard for wind turbines

BUSINESS CHALLENGE

Foundation integrity is one of the most critical considerations in wind turbine design. Interaction between foundation and

soil has important effects on the wind turbine behaviour. For the manufacturers of wind turbine foundations, the

certification by an International Recognised Certification Body is a must and, depending on the country, it is a mandatory

requirement.

BENEFITS FOR YOUR BUSINESS

Confidence in your Design - Design Assessment certificate confirms that the wind turbine foundation is designed and documented in conformity with design assumptions, specific standards and other technical requirements, improving confidence of all stakeholders in the safety and stability of the foundation.

 

International Recognition - Bureau Veritas Certification France is accredited for the certification of wind turbine type and component by COFRAC* for IEC 61400 standards. Bureau Veritas Certification France is also recognized as a certification body by IECRE. Upon request, Bureau Veritas Certification France can certify against other specific standards.

 

OUR APPROACH

Wind turbine foundation analyses are performed by expert engineers with a strong technical expertise in wind and geotechnics. For each certification project, Bureau Veritas Certification sets a project organization with a multidisciplinary background: design review, independent analyses, material expertise and more.

Process: The certification process verifies all the foundation elements taking part in the structural design:

  • Standards applied;
  • Materials;
  • Load calculations;
  • Calculation notes:
    • Overall stability;
    • Soil bearing capacity;
    • Anchors resistance;
    • Rotational stiffness;
    • Punching; etc.

In addition, Bureau Veritas Certification has developed an innovative tool to perform independent analyses on wind turbine foundations according to IEC 61400-1 and Eurocodes.

SKILLS AND TOOLS

We bring decades of experience to complete your structural wind turbine challenges. Our services are delivered by highly

qualified and trained engineers performing calculations with the most appropriate and reliable software, such as LMS

Samtech Samcef Wind Turbines, Abaqus, ANSYS and more. A specific software to calculate wind turbine gravitybased

foundations has been developed by Bureau Veritas Certification engineers. Calculations are performed taking into

account soil characteristics, wind loads, and all structural elements constituting wind turbine foundation. The engineering

team can simulate all structural aspects of the foundation – conducting linear static analyses that reveal stresses and

deformations, durability based on fatigue calculations and overall stability. The design complexity must be handled

efficiently by advanced solver techniques that reliably capture structure behavior.
