It is well known that mechanical damage is the leading cause of failure in both gas and liquid transmission pipelines. These damages often involve pipes inflected with injurious dents containing gouges. Over the past several years, significant levels of research have been conducted around the world in an effort to address the critical issues associated with mechanical damage. These efforts have involved both experimental and analytical efforts. The principal aim has been to assess defect severity in terms of future behavior involving both static burst and cyclic pressure conditions. The intent of this paper is to present an overview of the current research observations including first-hand knowledge of the author as well as insights available from the current literature. In addition to issues relating to mechanical damage, information is provided relating to constrained dent configurations such as those created by rocks. Also discussed are several remedial options for repairing damaged pipes. The anticipation is that pipeline operators and others in the industry can benefit from this information in assessing defects discovered using tools such as in-line inspection.
