What kind of tool can an operator use to conduct integrity assessments by internal inspection?
Operators must follow ASME/ANSI B31.8S, section 6.2 in selecting the appropriate internal inspection tool. Any tool(s) used must be appropriate to detect anomalies associated with threats identified for the line being assessed. OPS expects operators to evaluate the segment specific risks associated with each portion of the line that could affect an HCA and determine the appropriate assessment technology or combination of technologies to confirm whether or not those specific threats are present.
