Accurate prediction of the spudcan penetration behaviour is essential for the safe installation of offshore jack-ups despite the complex challenges due to uncertainties. In this research, a novel probabilistic approach is proposed by defining and accounting for uncertainties as well as incorporating measurements of historical spudcan installations. This approach offers more reliable and cost-effective prediction for future spudcan penetration at both sampled and unsampled locations. A statistical range of the spudcan penetration profile and the severity of the punch-through failure is defined, which provides engineers with informative guidance about what actions should be taken before any jack-up installation.
