The demand for deep-sea oil and gas supply is increasing due to the higher demand on energy and security of energy supply. The pipelines for transporting oil and gas are constructed by joining high strength steel linepipes. Stresses and strains develop at various critical locations in the pipe during the manufacturing processes. The residual stress in the pipe can potentially lead to failure during welding and in-service. To achieve a defect-free pipe and to have a better understanding of the integrity of the pipelines when pressurized in-service, it is necessary to know the residual stress distribution in the pipe and the weld. In this study, detailed measurement of residual stress/strain will be carried out to improve our understanding of failure mechanisms of linepipes and to develop a capability to be able to control the residual stresses in the linepipes.
