RESIDUAL STRESSES IN LARGE STIFFENED TUBULARS USED IN OFFSHORE STRUCTURES

The residual stresses in large stiffened tubulars which are used in offshore structures are studied. Formulae were developed for estimating weld shrinkage forces, and classical cylinder theory was then applied to determine the response of a stiffened tubular to these forces. The theory was verified by taking measurements on a model tubular, and then used to estimate residual stresses present in the full size tubulars in three existing structures in the North Sea. The information is being used in Britain in an assessment of buckling rules for these members. Changes in fabrication procedures which would reduce levels of locked-in stress have been proposed.
