Extended Analysis for Initiation of Local, Lateral Displacements in Heated Submarine Pipelines

Abstract

Earlier solutions for this pipeline lateral-buckling problem are reviewed. A new, straightforward solution procedure is presented with illustrative problems and design curves. The new procedure can be implemented easily with a simple digital computer program. The solution gives a theoretical upper bound for the axial load that can be developed through heating. This upper bound can be helpful in the early stages of pipeline design.
