초록

To meet the increasing demand for energy around the world, offshore and subsea energy development is constantly being conducted.
This trend is accompanied by an increasing demand for pipeline installation, which brings numerous problems, including those related toaccessibility, high pressure, and corrosion. Among these, corrosion is a primary factor in pipeline fractures, and can cause severe environmental andindustrial damage. Hence, accurate corrosion assessment for corroded pipelines is very important. For this reason, the present study investigated themechanical behavior of an idealized corroded subsea pipeline with an internal/external pressure load using the commercial FEA code ABAQUS.
Then, the analysis result was compared with corrosion assessment codes such as ASME B31G, DNV RP F101, ABS. Finally, a fitness-for-serviceassessment was conducted.
