Decommissioned Sites and Abandoned Wells

Pipeline crossings at waterways represent areas of elevated risk. For operators, maintaining accurate knowledge of pipeline location and condition at these crossings is essential. Consistent with PHMSA expectations, monitoring pipeline position and movement at water crossings enables early identification of exposure or instability, supports timely mitigation measures, and helps reduce the likelihood of pipeline failure and environmental impact.

Bending strain can develop in pipelines as a result of ground movement, geohazards, or changes in support conditions, increasing the risk of mechanical damage or loss of integrity. These effects are often localized and may not be apparent through traditional inspection approaches alone. Consistent with PHMSA integrity management expectations, identifying and characterizing bending strain supports early recognition of abnormal loading conditions, enables risk-based assessment, and informs timely mitigation actions to maintain safe pipeline operation.

Pipeline depth of cover represents a primary protective measure against third-party interference and external damage. Changes in terrain, erosion, construction activity, or environmental conditions can reduce cover over time, increasing exposure and risk. Consistent with PHMSA integrity management expectations, monitoring depth of cover supports early identification of exposure, enables risk-based assessment, and informs timely mitigation actions helping operators maintain safe, reliable, and sustainable pipeline operations.
