Modelling of Pipeline and Cable Flotation conditions

This paper aims to give a new perspective on physical modelling investigation of pipeline/cable flotation in post-jetted fine grained soils. The effect of bed preparation on soil resistance was assessed by performing pipeline pull-out tests in clays at various moisture contents. Two bed preparation methods were compared. The penetration of the pipe/cable through the fluidised soil, drags water lenses into the clay and leaves the soil in a disturbed state that persists and affect the mobilization distance of the pull-out tests. The mobiliza-tion of resistance is found to be dependent on the simulation of pipeline/cable installation process and em-bedment ratio (H/D)
