If I have hydrostatically tested my pipeline to a test pressure different than those listed in table 3 of ASME/ANSI B31.8S, how can I determine an extended reassessment interval?
Operators may use straight-line interpolation to determine acceptable intervals between the 5, 10, 15, and 20 year intervals listed in Table 3. In no case must operators reassess more frequently than once every seven years unless such frequent reassessments are determined necessary by risk assessment. • Remediation [Top] [Bottom] FAQ-56. Do the anomaly repair schedule requirements in 192.933(d) apply to all previous internal inspection runs performed by the operator, or just the integrity assessments required by Subpart O (i.e., the baseline assessment and subsequent integrity assessments)? [06/09/2004]Answer: The anomaly repair schedule requirements in 192.933(d) apply to baseline assessments and subsequent re-assessments required by the new integrity management rule. Prior internal inspection tool runs do not need to comply with the 192.933(d) criteria unless the pipeline segment inspection is declared to be a baseline assessment as described in 192.921(e).
