Characterisation of Marine Pipelines Behaviour During Fabrication Process and in Laying Conditions

The aim of the study has been the development of the numerical model of marine pipelines for deep water applications: since very few experimental data are available about pipes behaviour beyond 2 000 m depths, it is particularly important to laying contractors the availability of good simulation models. Many factors play a significant role in pipe resistance to external pressure, among which pipe thickness, diameter and material but also the load history must be taken into account, due to the high non-linearity of the mechanical syste
