Prediction of Spudcan Penetration Depth in Multiple Layers with Sand Overlying Clay
The conventional prediction of spudcan penetration depth in multiple strata, especially the strata with sand overlying clay profile, usually has a certain deviation with the field data. In this paper, a numerical method was proposed to analyze the ultimate penetration depth for spudcan in the multi-layered profiles with sand overlying clay, and the feasibility of this method was verified by the field data. Comparisons with the approach recommended in SNAME (2002) were also included, and the proposed method showed a significant improvement in predicting spudcan penetration depth in the multiple strata with sand-over-clay profile.
