NUMERICAL OPTIMISATION ASSOCIATED WITH THE INFLUENCE OF EXTERNAL FACTORS AND PATCH REPAIR FACTORS ON PIPELINES

Abstract Pipeline maintenance is an important process for increasing the useful life of the various structures used to transport fluids, reducing leaks and improving pipeline operation. In this work we have used numerical optimisation to determine the main factors affecting the repair of cracks in pipeline structures. We studied the most important environmental factors present around pipelines, such as humidity and the thickness of the patch used to maintain the pipeline structures.
