133836 - Managing Pipelines’ Total Stress Landscape With Advancements in In-Line Inspection-Based Bi-Axial Stress Measurement Technology 

Abstract: 

Over 15 years ago, pipeline operators requested the development of an in-line inspection (ILI) axial strain measurement tool to support their geohazard management programs. Since then, Axial Strain Measurement Inspection Service (AXISS^TM) has been employed on over 25,000kms of pipeline with many high strain locations successfully identified and mitigated. Like any new technology, it took AXISS^TM a few years to become a unique, established and proven tool for a pipeline operator to assess geohazards, movement and other strain-related threats. Over the years, the operators’ experience has provided key insights as to where the current technology strengths lie and of course where enhancement with additional information could further optimize their integrity engineers’ more complete understanding of stress and strain-based threats to develop proactive mitigation strategies and importantly conduct more cost-efficient repair programs, ensuring their pipelines’ safe operation.

This paper presents Baker Hughes’ response to these learned and clearly defined needs and introduces a new AXISS^TM EPS stress measurement inspection technology that adopts all the needed advancements by providing detailed information on the entire stress landscape of both active loading and residual stresses. The proprietary Baker Hughes sensing technology utilized by the new tool is a mature stress measurement technique that has been successfully used for the last three decades to deliver bi-axial stresses for flexible pipeline riser systems in the offshore oil and gas industry.

This paper will provide a comprehensive overview of the new bi-axial stress tool technology, its rigorous validation and test results. In addition to that, it will give an insight to some of the game-changing and unique capabilities it provides to further discriminate the criticality of the pipeline stress condition at any given location along the pipeline driving necessary and timely repair. Furthermore, comparison of this new AXISS^TM EPS stress data relative to the earlier axial strain inspection data will be provided to demonstrate the additional benefits these new capabilities will provide in efficiently and effectively managing pipeline strain based threats.
