Pipe Stresses Induced in Laying Offshore Pipeline

Abstract

Part 1: No reverse curvature. Part 1 of this paper considers the bending stresses induced in the unsupported length of pipe as it feeds off of the supporting stinger with no change in sign of curvature. The effect of various parameters on the stresses is treated. Part 2: Reverse curvature. Part 2 considers the case which occurs when the pipeline tips over the end of the stinger and undergoes reversed curvature before coming back into contact with the stinger.
