This project conducted research with an intent to improve the in-ditch NDE measurements and subsequent assessments of SSWC. To do this, pipe joints containing natural SSWC samples were sourced from multiple PRCI operator members who consented to having the pipe destructively tested (post-NDE evaluation) to obtain a truth data set against which NDE techniques’ accuracies could be assessed. The SSWC characteristics observed with destructive testing were documented and formed a stand-alone data set for use both in this study and for future research. The study also evaluated previously issued...
This project conducted research with an intent to improve the in-ditch NDE measurements and subsequent assessments of SSWC. To do this, pipe joints containing natural SSWC samples were sourced from multiple PRCI operator members who consented to having the pipe destructively tested (post-NDE evaluation) to obtain a truth data set against which NDE techniques’ accuracies could be assessed. The SSWC characteristics observed with destructive testing were documented and formed a stand-alone data set for use both in this study and for future research. The study also evaluated previously issued industry guidance for identifying SSWC (and provides updated guidance) as well as determining the in-ditch performances for SSWC depth sizing for multiple NDE technologies. These performances were documented, and a best practice recommendation was put forward for determining SSWC groove depths for future NDE validation digs.
