The interaction between a spudcan and an existing footprint is one of the major concerns during jack-up rig installation.When a spudcan is located on or nearby an adjacent footprint slope, there is a tendency for the spudcan to slide towards the centre of the footprint, inducing excessive lateral forces and bending moments to the rig. Adverse spudcan displacement could result in an inability to install the jack-up in the required position, leg splay, structural damage to the leg, and at worst, bumping or collapsing into the neighbouring operating platform. This paper reports the results from a series of 1g and centrifuge model tests investigating spudcanfootprint interactions in clay. Three ..View full abstract
