Abstract: Operators and contractors have been running pigs successfully for years. Every so often, a problem occurs and one becomes stuck, stalled, or damaged in the pipeline. As the need for innovative one-off pigs for specialist applications arises, the risk of this occurring increases. Sufficient planning and analysis should be performed to allow the pigs to run successfully and perform their duty in the line effectively; this includes stringent testing, CAD work, and analysis. This paper looks at the main reasons for pigs sticking and stalling in lines, and examines what can be done about it. The paper also looks at several different categories of failure, identifies the root cause of the problem, and looks at how these scenarios might best be avoided. The figures incorporated in the paper may be used as guidelines for consideration and avoidance of the problems discussed.
