Holding capacity of suction anchor according to loading position using p-y method

Abstract

Suction Anchor is an efficient mooring anchor that can carry heavy load in deep water. The uplifting bearing capacity of suction anchor is changed respect to loading position of anchor. There are previous researches on the behavior of suction anchor with different loading point and direction. In this study, holding capacity of suction anchor with large diameter according to loading positions was evaluated by p-y method which is widely used in the evaluation of lateral behavior of foundation based on the theory of beam on elastic foundation. Especially, size effect of suction anchor with large diameter, base shear and moment reaction are considered in this study. The analysis on holding capacity of suction anchor using p-y method is simple and can be easily used than other previous conventional analysis methods. Through comparing analysis results with established results of previous study, the holding capacity of suction anchors with the new proposed method using p-y method were estimated in this study.
