Narrative
Line segment was started after a period of inactivity and the line pressures and volumes indicated a possible leak. Line was shut down and an aerial surveillance revealed a spot located in the sam houston national forest near new waverly, texas. A contractor confirmed the leak. A girth weld on the bottom of the pipe had cracked. Metalurgical analysis revealed a combination of inadequate penetration at the weld root and a high-low offset condition providing a stress concentration that served as the origin of the fracture.The line segment was purged and integrity projects have been completed. The line was restarted on november 1, 2011 at 09:45.
