Abstract

This study has established a novel spudcan shape, with a flat base and four holes through the base, for easing spudcan ­footprint interactions, which is one of the major concerns to the jack-up industry. By comparing with the performance of a conventional spudcan, the novel spudcan was shown to reduce the maximum horizontal force and moment by 42% and 46%while installing next to a footprint. The global response of a jack-up rig was captured through numerical modelling. Finally, the effectiveness of the novel spudcan was confirmed through centrifuge model tests, varying footprint geometries, strength of clay, offset distance of reinstallation.
