Abstract Helical piles have been widely used onshore which can withstand compressive and tensile loads. As a promising foundation for offshore wind developments in deep water, helical pile has advantages of quiet installation and significant uplift capacity. In this paper, numerical analyses are conducted to investigate the load bearing mechanism considering the contributions from shaft and helical plate. The effects of helical plate embedment depth, interface roughness and shaft diameter ratio are studied. A discussion is presented on the terminology adoption depending on the contribution from the helical plate and the shaft.
