HCE DESIGN GROUP’s Post

The #planning phase for the repowering project in Meppen-Teglingen is coming to an end. The existing Enercon E66 wind turbines will be replaced by nine #Vestas V172 wind turbines. This week, we are delivering the execution planning (static calculation as well as formwork, pile and reinforcement plans) for the foundation and pile construction. The overall design requires a #hybridtower variant due to the hub height of 175 meters. The concrete tower extends to around 104 meters above ground level. The location of wind turbine number 3 has a special feature that is not uncommon in repowering projects. Like the dismantled existing plant, the new construction also requires a #foundation on piles due to the difficult ground conditions. The pile arrangements of the old and new plants overlap. Therefore, a special pile pattern must be taken into account when dimensioning the deep foundation, which makes the static considerations complex. In this case, the foundation is constructed on reinforced concrete driven piles of the Centrum type with an edge length of 450 mm and a length of around 17 m. A total of 80 #piles are required for the new Vestas V172. The old plant was supported on exactly half that number of piles. This and our graphic shows the enormous development of the #windenergy industry over the last 20 years. #EPC-M for your #repowering
