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.]]>Kusha, A., M.R. Mogadam and F.S.M. Meysam Abutorabi,20111120002005ANSI/ASME,1991pp: 55pp: 55Belachew, C.T., M.C. Ismail and K.
