Threats and Integrity Management -- Anomaly Detection and Characterization

NYSEARCH, with its contractor Analatom, completed lab and field testing on corrosion sensors currently used by aircraft for corrosion monitoring. While primarily applied to coated steel, these sensors can measure corrosion rates in real time on the external surfaces of pipe using a unique linear sensor array. The tests provided positive confirmation that the micro-linear polarization resistance sensors can be practically applied to provide real-time monitoring of corrosion on natural gas pipelines. More work is needed to further validate their use and to advance it to commercialization.

The technology addresses one of many challenges of an effective corrosion monitoring program to measure corrosion rates in real-time specifically in conditions where corrosion potential is known or suspected to exceed the norm. This technology improves the ability to conduct a thorough inspection leading to increased safety.

Increased Safety - External inspection and corrosion monitoring are one of the critical components of a pipeline integrity program. Real-time monitoring provides an effective means to detect and correct corrosion issues.
