Characterization of measurement uncertainties in crack profiles assessed by in-line inspection tools

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

Measurement quantities representing crack profile geometric parameters are evaluated for their influence on the failure pressure of pipelines. Several representative cases of pipe designs are considered to isolate the influence of geometric parameters from that of pipe parameters such as pipe size, grade, wall thickness, and toughness. The results indicate the ratio of crack profile area to the crack length as the most influential geometric quantity. Using this measurement quantity, it becomes straightforward to evaluate the reliability of the ILI measurements for crack profiles and quantify the associated measurement uncertainties with probabilistic measures.
