Narrative
The 5-6 line which transports finished lube products from the motiva port arthur refinery to the motiva port arthur marine terminal, was discovered to be leaking on july 5, 2017. As a result, the line was excavated for inspection and repair. Failure was observed along the longitudinal axis of the pipe in one area, measured to be approximate 17 inches long. Cross section of pipe containing the failure was submitted to an independent metallurgical testing lab for analysis. Based on extensive examination, the conclusion was made that in most likelihood, failure was the result of ductile fracture along a non-optimal erw seam. The failure onset was facilitated by: 1. Intermittent patches of lack of fusion along the erw joint and 2. Significant od surface wall loss due to preferential corrosion along the side of the pipe corresponding to the erw. It is suspected that the out of service, blocked in line over-pressured due to thermal expansion but exact failure pressure could not be determined through the failure analysis.
