Abstract

Pipelines are the safest and reliable way for oil and gas transmission. Failures due to corrosion defects are of major concern in maintaining pipeline integrity. A number of solutions have been developed for the assessment of remaining strength of corroded pipelines. Methods of assessing the corrosion metal loss defects have been available for decades, for instance the ASME B31G method. ASME B31G and Recommended Practice DNV-RP-F101 are the available coded methods that are used as reference codes for corroded pipelines. They provide guidelines for evaluating the remaining strength of corroded pipelines subjected to internal pressure loading and combined with longitudinal compressive stresses for single defect, multiple defects and etc. In this project, a corroded pipe will be simulated using ANSYS Software. The Finite Element Analysis (FEA) simulations will be conducted for various idealized geometry of the corrosion defects subjected to internal pressure loading only. The results from the simulations will then be compared to the coded methods; ASME B31G, DNV-RP-F101 and the experimental results. The Maximum Allowable Burst Pressure (Pb) and the best approach for evaluating the remaining strength of corroded pipelines will be determined from the simulations
