SolAres Srl, a joint venture between Solgeo and Aresys, is the supplier of e-vpms®: Eni's innovative technology for Pipeline Leak Detection and Pipeline Integrity Monitoring. Already deployed worldwide on over 1,700 km of pipelines, the technology proved to dramatically reduce the number of Third Party Interferences and their economic and reputational impacts.

The technology, after the installation of a minimal set of non-invasive sensors on existing derivations, elaborates in real-time the vibroacoustic waves propagating inside the pipeline.

The system is able to detect and precisely localize events as leaks and impacts occurring on the pipeline, with excellent reliability, precision and response time.
The vibro-acoustic system (e-vpms®) was developed by Eni SpA mainly to localize leakages, although has shown over the years the capability of detecting impacts and illegal tapping precursor events. This technology is able to detect and localize third party interferences (TPIs), such as the manual digging close to the pipeline, by exploiting similar physical phenomena involved in shell/fluid stimulation by impacts and tapping operations. Such a sensitive system requires sensor specifications stricter than in the case of leak detection; in particular, with respect to the acquisition frequency and the inter-distance among vibro-acoustic stations. The fullest deployment configuration of the e-vpms® provides an integrated platform able to cover a wide spectrum of events related to the “life-cycle” of illegal activities, from digging, passing through illegal tapping to the leakage itself.
