The jack-up rig is the most common type of mobile offshore platform that can be deployed in active faulting zones. However, its interaction with earthquake–induced fault ruptures is poorly understood. Fault rupture–foundation interaction is of paramount importance to the overall response of the structure to faulting–induced loading and in developing deployment or platform design strategies that may mitigate risk to the platform. In this paper 3D finite-element (FE) modelling is used to explore the interaction between ruptur-ing faults and spudcan foundations. The FE models are initially employed to explore the interaction between spudcan foundations and a rupturing normal fault, followed by a parametric study investigating the influ-ence of the fault rupture location on the structure.
