When performing jacking operations in layered soil conditions, a punching failure mechanism may occur. Punching failure is a brittle phenomenon. It can lead to rapid leg penetration, which could have dramatic consequences for the jack-up structure. Several approaches are available, in literature and relevant standards that allow assessing the punching capacity. In the current paper, Authors focus on one of the more recent methods (by Hu et al. 2014) and calibrate this model with in-situ measured peak punching capacities.
