Abstract
Jack-up drilling rigs are usually founded on three shallow footings. Under wind, wave, and current loading off shore, the footings of these tall multi-footing systems transfer large moment loads in addition to self-weight, horizontal load, and even torsion to the underlying soil. To be able to deploy a jack-up safely at a particular offshore site, the unit's capacity to withstand a 50 year return period storm is required to be checked in accordance with current guidelines (Site specific assessment of mobile jack-up units, The Society of Naval Architects &Marine Engineers). As the overall system behaviour is influenced significantly by the footing restraint, models that account for the comple..
