Brief description Mobile jack-up structures perform most of the world's offshore drilling in water depths up to 120m, but have a higher accident rate then fixed installations. To improve their safety, this research will develop the framework for the integrated assessment of jack-up behaviour in three dimensions. To achieve this, an advanced plasticity model that describes cyclic behaviour of the circular shallow foundations of jack-ups in both clay and sand will be developed and incorporated with random wave loading of seas in a dynamic structural analysis program. The anticipated advantages of the modelling techniques will be assessed against existing two dimensional industry guidelines and monitored field data.
