The objective of this project is to assess the integrity of corroded pipelines due to pitting type of corrosion defects. The scope of this project will be the finite element analysis of corroded pipelines on pitting type of corrosion defects and its modelling. This project was focused on the offshore pipeline. The type of pitting considered was on the single type of pitting. This project considered only the internal pressure as the loading. The software used to model the pipeline is CATIA and the software used to do the analysis is named ANSYS. The results of FE modelling were compared to the results of available codes used by the industries. The results from the available codes were referred as the empirical results. There were 2 codes used in this project namely DNV RP F101 and ASME B31G. As a result from this project, the integrity of corroded pipeline as well as prediction of remaining strength of corroded pipeline will be obtained. The successful outcome of this project will be a great helping guidance for industrial application towards assessing the integrity of corroded pipeline subjected to internal pressure only
