Abstract
As the size of offshore structures has been increasing, the interest for foundation systems with large capacity is also rising. Along with this trend, the studies of suction piles, which are widely used as mooring anchor systems, that can develop large capacity are in progress. In this paper, the concept of multiple suction pile anchors which are composed of several suction piles connected in parallel is introduced. Two types of multiple suction pile anchors are presented, and one type is that two single suction piles are connected, and the other type is composed of three single suction piles connected in parallel. The pullout behavior of the single suction pile anchor and the two types of multiple suction pile anchors are investigated using numerical analysis. Numerical simulations using ABAQUS software are performed and the three dimensional model is deployed to duplicate the body shape of suction pile anchors. The load and displacement of the suction pile anchors are computed under continuous horizontal loading, and the pullout capacity of each type of suction pile anchors are evaluated.evelop large capacity are in progress.
