To study the effects of spudcan penetration on the adjacent foundations of offshore platforms, experiments and numerical simulations (using business software ABAQUS) are carried out. It is shown that the penetration of spudcan can cause the soil layer affected in an annular zone. The affected zone has a maximum width of one times the diameter of the spudcan. The deflection of the platform’s fou...

This study investigated the behavior of spudcan foundation jack-up vessels offshore wind turbines during undrained vertical penetration into thin stiff-over-normally consolidated clay. Large deformation finite element (LDFE) analyses were used to simulate continuous seabed surface. Detailed parametric analysis was performed explore a range normalized soil properties and layer geometry roughness...

When a jack-up installed at a clay location and then leaves; it can create several meter deep footprints. In case of soft clay, the spudcan may have actually penetrated much deeper than the observed footprints. When the penetrated spudcan is pulled out, much of the soft remolded clay will flow around it and go back into the hole. This event, leaving a deep region of disturbed soil. The disturbe...

The nonlinear behavior of spudcan foundation will lead to the decrease rotational stiffness spudcan, leading increase stress at critical member offshore jack-up drilling platform. Secant is used represent value linear model when soil changes from elastic elasto-plastic and then plastic. In this paper, “wished in-place” small strain finite element analysis (SSFE) simulate load-displacement respo...
