... Abstract Mechanical damage is a leading cause of serious pipeline incidents worldwide. Anomalies caused by it, including those associated with third-party damage, are challenging to detect, classify and size. In particular, in-line inspection (ILI) systems have had difficulty inspecting dent...

... for dented pipelines. The proposed methodology can be used as a part of engineering assessments in mechanical damage integrity management programs to improve the pipeline operator’s understanding of a dent’s remaining life and enable a more appropriate repair timeline. mechanical damage dent...

... Mechanical damage, caused by externally applied forces, can deform the cylindrical shape of a pipe, scrape away metal, change material properties, and leave residual stresses and plastic strains. Mechanical damage is especially detrimental when it leaves the potential for delayed failure...

..., mechanical damage, arc strikes and girth weld defects. The volumetric corrosion defects included both isolated defects and pairs of interacting defects. All the defects and details such as the girth welds were assessed for fatigue failure in addition to failure at the Maximum Operating Pressure. This paper...
