Pipeline networks are constructed with the aim of transporting different chemical and petrochemical products, in liquid and/or gas phase conditions, over long distances. Despite the effectiveness of pipeline transportation, unexpected and sudden leak events can cause not only unnecessary waste of limited resources but also serious environmental pollution problems. Crossing densely populated areas and natural reserves, the operational reliability of pipelines should be improved, minimizing the risk of leakages. Thus, proactive actions should be conducted on pipeline networks and one concrete example is the pipeline monitoring.

The object of this project is the development of a low cost and low energy wireless sensor system for the immediate detection of leaks in metallic piping systems for the transport of liquid and gaseous petroleum products in a noisy industrial environment. The method to be followed will be based on processing the changes monitored in the acoustic spectrum of sound signals appearing in the pipeline walls due to a leakage effect and will aim at minimal interference in the piping system. It is needed to use low frequencies to detect and characterize leakage in order to increase the range of sensors and thus to reduce cost. The method will focus only on the sounds produced during the leakage while intermittent processing will be applied with the potential to further reduce energy consumption and increase leakage detection realiability in a noisy environment.

Esthisis official start

Esthisis officially started on 28 of June. This was the beginning of a journey, full of challenges and hard work.

CONSORTIUM

The consortium of the Esthisis project comprises partners with an impressive academic and business track record among with proven expertise on a variety of fields related to computer architecture, spectrum analysis and mostly fluid mechanics. Through joining of the above partners' fields of expertise, the Esthisis project will focus on the development of a smart sensor system for detecting leakages, as well as the software tools that automate the procedures of architecture-level exploration of these platforms and perform application mapping onto them, with the usage of state-of-the-art technologies.
