Finite Element Analysis of Corroded Pipelines

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
