Narrative
At 5:17 (rmt) on december 4, 2020 the magellan commerce city to fountain 6" pipeline experienced a loss in pipeline pressure initially believed to be an operational upset due to upstream product supply. At 6:41 (rmt) a code red was initiated and field personnel were dispatched to isolate the pipeline. A release was identified near mp 0.17 along 56th ave. Cleanup activities were initiated and the pipeline failure was cutout for metallurgical failure analysis. Results of the metallurgical analysis indicate the failure originated at an erw selective seam corrosion groove. A crack initiated at the base of the groove and grew to a depth where the remaining ligament could not sustain the internal pressure of the pipeline. Supplemental/final (6/7/2021): parts d4, d4a, d8c, d8d, d8e,g1, part h updated based on metallurgical analysis.
