The axial resistance to movement of a marine pipeline is an important factor in the assessment of the stability of subsea and onshore pipelines. Furthermore, the axial resistance of a pipeline is an important component in various geotechnical design applications. A number of factors are responsible for evaluating the axial resistance such as pipe displacement, relative roughness of the pipe-soil interface and the conditions at which the mobilization is taking place (drained or undrained). Current design of pipelines is based on empirical pipeline-soil interaction model that cannot be applied to a wide range of situations/types of seabed in the field. The aim of this project is to develop and experimentally validate a phenomenologically based pipeline-soil interaction model for practical implementation in pipeline design standards.
