Leak detection in buried pipelines

A technique of leak detection in buried pipelines transporting hazardous chemicals has been reported in an article. The article mentions that "Distributed strain/deformation and temperature sensing for pipeline integrity monitoring is a useful tool that ideally complements the current monitoring and inspection activities, allowing a more dense acquisition of operational and safety parameters. The measurements can be performed at any point along the pipeline. Furthermore, the monitoring is continuous and does not interfere with regular pipeline operation in the way that other maintenance can. The method can also be applied to non-piggable pipes".
The article also mentions that the technique successfully detected a leak in a buried pipeline carrying brine. Read the article in this link.
