Research output: Book chapter/Published conference paperChapter


This chapter explores the effect of live pressure in pipelines on the design of composite overwrap repairs. At first the incorporation of the live pressure into the design of a repair in existing design codes is reviewed. Next, an analytical method is presented which shows that the live pressure does not have any effect on the repair design and it should not appear in the design equation. Finally, a finite element analysis model is presented that shows conformity with the analytical method and validates the recommendation to remove live pressure from the design codes formulae. © 2015 Elsevier Ltd.
