/ Convertible Pre-piling template

With offshore wind farms being built in ever deeper waters, there is a growing demand for jacket foundations to support the increasingly larger Wind Turbine Generators. These jacket foundations come in different designs to accommodate the varying conditions and parameters of the wind farm locations. Therefore, pre-piling templates have to meet the specific dimensions and geometry that each offshore wind farm demands. Investing in tailored pre-piling templates for single-use is very cost-inefficient. 

 

Huisman introduces the Convertible Pre-Piling Template, an economic and reliable solution for accurate piling.
