Abstract

The research has aimed to support the transition of oil and gas developments into deeper water and more remote conditions by developing analytical solutions for axial pipe-soil interaction and structural behaviour of pipelines impacted by submarine slides and high temperature fluctuations due to operating cycles. Analytical and numerical solutions were developed to estimate elastic stiffnesses for on-bottom pipelines, the impact of axial debris loading on pipelines and the critical lateral buckling load, and also to investigate pipeline walking mechanisms under cyclic thermal conditions.
