N2  - Failure due to corrosion defects has been the major problem in maintaining pipeline integrity. The loss of metal due to corrosion usually results in localized pits with various depth and irregular shapes which occur on its external and internal surfaces. An interacting defect is one that is located sufficiently close and able to interact with neighbouring defects in an axial or circumferential direction. The maximum allowable pressure that can be sustained in a pipeline with interacting defects is lower than it is in single defect due to interaction of neighbouring defects. Several methods are available to assess the corrosion metal loss defects in order to evaluate the Fitness-for-Services (FFS) of the corroded pipeline. In this study, extensive finite element simulations have been carried out to determine the burst strength of corroded pipeline with interacting defects. The Finite Element Analysis (FEA) showed that the failure pressure results of corroded pipeline with interacting defects were higher than the empirical values obtained from DNV-RP-F101 Code. © 2012 Asian Network for Scientific Information.
