Abstract: Subsea pipeline can always relate to corrosion. Different extends of corrosion, making pipeline behaviors unpredictable. It is vulnerable to damages due to the fishing trawl gears and most of the buckling problems are caused by impact and pull-over loads especially the most common practice of using beam trawl. In this research, finite element analysis Abaqus/CAE 6.13-1 was used to study the effect of maximum allowable operating pressure for flawed pipe relates to lateral buckling behavior of straight unburied pipelines on flat clay seabed induced by beam trawl pull-over loads with the usage of different types of steel grade. The primary purpose of this research is to provide a better description of various corrosion depth parameters incorporated with beam trawl pull-over loads and to examine the differences in usage of steel on their performance.
