A set of four operating coke drums experienced variable degrees of bulging and bulging-induced cracks. Internal laser scans were obtained for these drums to accurately define their geometry. Then, the severity of bulging was analyzed using stress and strain analysis techniques. In this paper, results of the two methods are presented and compared to failure history.
