Pile Design for WTG Foundations

A pile foundation transfers the WTG loads to the lower-lying ground, thereby providing an overall support to the structure. Geotechnical experience is a must for designing wind turbine foundation pile. CTE Wind designed piles with length varying from 10 to 70 meters.

Foundation piles transfer loads from the wind turbine foundation to lower-lying ground, thereby providing overall support to the structure. These piles carry concentrated loads and are subject to fatigue. As such, careful assessment of geotechnical conditions and proper interpretation of the soil reports’ drilling logs and laboratory data are critical, which is why CTE Wind has senior geotechnical engineers working on wind farm projects worldwide.

CTE Wind’s pile foundation designs solutions consider driven, bored and drilled piles as well as vibro piles and Franki piles. Once the pile solution has been chosen, the length and diameters, as well as the stiffness of the pile and the loads on top of it have to be determined. The compression, the tensile and the fatigue loads are taken into account to establish the calculation report and the final drawings stating the rebars and concrete volumes.

Piles for intertidal nearshore foundations

In current projects CTE Wind has designed pile foundations with lengths varying from 10 to 70 meters which is exceptional. The latter was designed and built in Asia in different nearshore projects on an intertidal sea-zone. CTE Wind also provided pile designs in Belgium, France, Germany, The Netherlands, Brazil, Serbia, Ukraine, Russia, and Finland to name a few.
