Rule Section: §192.917(e)(2)

Cyclic fatigue.

Rule Hierarchy:

• 192.917  How does an operator identify potential threats to pipeline integrity and use the threat identification in its integrity program?
  • 192.917(e)  Actions to address particular threats.
    • 192.917(e)(2) Cyclic fatigue.

Rule Language:

An operator must evaluate whether cyclic fatigue or other loading condition (including ground movement, suspension bridge condition) could lead to a failure of a deformation, including a dent or gouge, or other defect in the covered segment. An evaluation must assume the presence of threats in the covered segment that could be exacerbated by cyclic fatigue. An operator must use the results from the evaluation together with the criteria used to evaluate the significance of this threat to the covered segment to prioritize the integrity baseline assessment or reassessment.
