Our Services

Structural engineering for on-shore wind turbine foundations


CTE Wind presents its range of services and solutions to meet all your demands :


  • Verification of geotechnical interpretative reports to confirm if all necessary soil values are provided
  • Synthesis and grouping of soil values for foundation optimization for wind farms
  • Site Assessment to determine the required geotechnical site investigation campaign
  • Procurement Support in the selection of geotechnical contractors for the establishment of the geotechnical report


  • Designs following international standards and specific wind guidelines by respecting local country regulations
  • Preliminary designs (report and schematic drawing) to identify potential cost optimisations based on the geotechnical report and to compare required designs for different wind turbine models under consideration
  • Detailed designs (full structural report and construction drawings) based on our experience and the requirements of turbine manufacturers, ensuring a safe, reliable and economical design. Complete verifications including : loads, partial security factor, dynamic rotational stiffness, SLS and ULS, the analysis of fatigue loads and the calculation of reinforcements
  • Bankable reports: Designs which can be submitted for approval by the insurers, banks, manufacturers and others. We accompany our customers until the final validation with these organizations

Complementary competences

  • Anchor cage design : detailed dimensioning including fatigue verification, grout determination, bolt post-tension forces and fabrication drawing
  • Design of all types of piles (driven, bored, etc.) adapted to different soil conditions including the geotechnical calculation to determine their length and allowable stresses
  • Innovative design solutions (high pedestal, soft-spot, rock anchor foundation, near-shore foundations and others). Engineering foundation solutions for turbine prototypes (i.e.: Offshore prototype, two-blade turbine, guyed mast, folding mast, etc…)
  • Design Reviews/CAT III Checks: full independent calculations and cross checking against design by 3rd party consultant with proposal for improvement/optimization of these foundations if necessary


  • Fact finding Site visits to visually inspect anomalies
  • Root Cause Analysis Assessments
  • Site inspections to verify satisfactory repair of damaged foundations


  • On-site inspection upon reception of the reinforcements before concrete casting
  • Construction Monitoring of foundations
  • Construction Quality Assurance of foundations through verification of checklists and test results
