Records may be supplemented or corrected and do not represent final agency causal findings.\n\nReport number: 20030035.\n\nOperator ID: 405.\n\nReported incident date: 3/23/2003.\n\nCause detail: BUTT WELD\n\nCause detail: THERE WAS A LEAK ON THE 2-501 36\" MAINLINE BETWEEN MLV 53 & 54, FOLLOWING THE DISCOVERY OF AN ICE FORMATION ON THE SURFACE OF THE RIGHT-OF-WAY. INITIAL DISCOVERY INDICATED A LEAK AND NO FIRE PRESENT. A PARTIAL THROUGH-WALL WELD CRACK, INTRODUCED IN THE IC AREA AT THE TIME OF THE WELD WAS MADE, WAS NOT DETECTED DURING RADIOGRAPHIC INSPECTION IN THE FIELD. A COMBINATION OF AXIAL STRESS AND APPLIED MOMENT, DUE TO MISALIGNMENT OF THE PIPE SECTIONS, OVERLOADED THE GIRTH WELD AND PROPAGATED THE PRE-EXISTING CRACK THROUGH WALL, CAUSING THE LEAK.\n\nPHMSA trend classification: significant incident, not serious.\n\nPHMSA standardized cause: MATERIAL FAILURE OF PIPE OR WELD — BUTT WELD.\n\nPHMSA indexed costs: $174,000 reported total cost, $117,487.179 in 1984 dollars, $144,256.41 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data. They do not represent final agency causal findings.","truncated":false,"body_characters":1444}
