Abstract
Offshore jack-up drilling rigs are subjected to loading from wind, waves, and current in addition to their self- weight. This applies combined loading in all six degrees-of-freedom in space on the footings. Although the foundation- soil interaction is crucial to the overall response of a jack-up structure, current state-of-the-art models to predict jack-up footing behaviour, developed using data from single footing experiments, have not been validated for such multi-footing systems under general combined loading. This paper introduces the experimental development of a three-legged model jack-up and loading apparatus designed to investigate the rig's response - in particular the footing load ..
