In this context, the economy of jacket foundations has gradually emerged. The jacket foundation of an offshore wind turbine needs to drive steel pipes into the water through a pile driving positioning frame. The diameters of steel pipes are different for different projects. Especially when a project involves jacket foundations with different pile diameters, if there is no suitable pile driving positioning frame, it will affect the construction progress and increase the construction cost.
