Screw pile design optimisation under tension in sand [PDF]
Proceedings of the XVII ECSMGE-2019, 2019 Many applications in offshore engineering, such as floating or jacket-founded wind turbines or wave energy converters, require a significant uplift capacity of their foundations to be kept in place. Straight-shafted or suction piles in sands have a limited uplift capacity as they resist by friction only.
