Pipeline Revalidation using Quantum Sensors
Abstract
To ensure ongoing safety, compliance, and operational efficiency, WWU uses in-line inspection tools (commonly known as PIGs) to monitor the internal condition of these pipelines. These tools are critical for detecting corrosion, cracking, deformation, and other defects.
A significant challenge within the existing P18 pipeline network is the uncertainty surrounding weld integrity. For many legacy sections, the original inspection records are incomplete or unavailable; without reliable weld data, it is difficult to determine whether these joints remain structurally sound or if deterioration may be developing below detection thresholds.
The project endeavours to determine whether advanced sensing can effectively assess the condition of target pipeline welding and other features, defects, or degradation, and whether advanced sensors can be applied to existing or new PIGs to perform the weld inspection required.
The technology will provide a more comprehensive understanding of the condition of the existing network and its overall integrity and longevity, beyond what is achievable through current testing methods. This enhanced insight will enable Gas Distribution Networks (GDNs) to reclassify pipelines where appropriate, thereby avoiding significant capital expenditure associated with uncovering welds of unknown quality during capital projects or damage assessments. Furthermore, as reliance on natural gas declines, this capability will enable the repurposing of existing assets, rather than leaving them redundant or decommissioned.
