IN-SERVICE MECHANICAL BEHAVIOUR OF HEATED PIPELINES LAID ON SEABED SURFACE

An estimate is made of the maximum axial load that may exist in a long pipeline resting on the ground when carrying hot or pressurised fluids. Lateral deflections of the pipeline are considered with the use of a specific pipe-soil interface model as well as beam pre-buckling and initial post-buckling equilibrium studies. The determination of offshore pipelines in-service maximum axial loads is useful for mechanical design of pipeline ends systems, appraisal of pipeline behaviour along suspended spans and similar design considerations.
