On June 2, 2016, C-FER’s Brian Wagg presented at the Pipeline Safety Seminar in Daegu, Korea to over 400 industry leaders. During the presentation, Mr. Wagg provided insights on integrity management.
At the 10th annual International Pipeline Conference in Calgary, Alberta, C-FER presented a paper that analyzes the performance of an ultrasonic testing (UT) tool in detecting stress corrosion cracking (SCC) features using the ILI run results and excavation data from several operating pipelines. Analysis of the excavation data shows that the POD for SCC features is dependent on both the maximum depth and the longest interacting length of the feature.
At the 10th annual International Pipeline Conference in Calgary, Alberta, C-FER presented a paper on the results of PRCI project NDE-4E which examined the performance of various crack ILI technologies based on an industry data mining exercise.
Maintaining pipeline integrity in the face of progressive deterioration mechanisms, like corrosion and cracking, is an ongoing challenge for pipeline operators. In general terms, the process for defect specific integrity management involves four key steps:
Identify significant features;
size the features;
project feature growth with time; and,
assess the features' remaining life.
