A plasticity model is presented to describe the drained vertical load-displacement response of untrenched offshore pipelines on calcareous sand. The predicted plastic response during monotonic loading and elastoplastic behaviour during reloading is shown to compare well with experimental data. The model can be used to evaluate total settlement of a pipeline under both monotonic and cyclic loading conditions. Using the framework presented in this paper, it is possible to extend the model to simulate the vertical load-displacement response of other types of shallow foundations and to cover undrained conditions.
