The purpose of this work is to study the reliability of a network for the monitoring of leaks in a hydrocarbon system.
Initially, natural gas is mentioned as the most basic and most common gas in the category, in its transport using pipelines and then described the characteristics and the main parts of a transmission system. The issue of a leak from such a system is indicated and the leakage detection systems applied and the monitoring techniques used to avoid risks are mentioned.
Special reference is made to the Wireless Sensors Network (WSN) analyzing the elements from which they are composed. The WSN are shown as an ideal way of monitoring leakages in a hydrocarbon transport system using sensors to detect the gas in the atmosphere.
An important issue that emerges is that of the reliability and sensitivity of the system. Reliability refers mainly to the operation of the monitoring system, to the ability to detect, to transfer data and to the communication between nodes.
Finally, it is proposed to install a WSN in a transport system that crosses land sections and concerns parts of the pipeline that are above the ground or buried and there is a possibility that a leak may occur during operation.
