| Abstract: | Outer loading condition of subsea systems in deep water is discussed. The mostly used types of foundations for subsea production equipments are compared. The relative merits of pipe pile, suction pile and mud mat is commented. The load applied on the suction pile in working con- ditions is analyzed. Based on the loading condition, the method used for axial and lateral bearing capacity calculation of pipe pile is suggested for the calculation of the bearing capacity of suction pile. The validity and limitation of the method is discussed. |
