Real Time Leak Detection Software

The software is called VIVIUNAM and performs logical deductions in real time, allowing to identify the type of failure and get to the root of the problem, thus avoiding a waste of time, by digging or manually searching for the problem throughout the pipeline

Often, water, gas or oil distribution networks present leaks in storage tanks, pumping failures or illegal connections exist. In order to avoid economic losses due to these causes, Cristina Verde Rodarte, researcher at the Institute of Engineering, of the Autonomous National University of Mexico (UNAM), designed a virtual guard that immediately detects abnormalities in any type of duct.

The software is called VIVIUNAM and performs logical deductions in real time, allowing to identify the type of failure and get to the root of the problem, thus avoiding a waste of time, by digging or manually searching for the problem throughout the pipeline, said the researcher, who is also member of the Academy of Engineering.

The virtual vigilante works with an algorithm, which by the laws of physics and the application of a mathematical model of fluid mechanics, calculates a series of data indicating what is the behavior of gas, water or oil pipelines in normal operating conditions. These, in turn, are compared with the record of pressure measurements within the pipe and the difference between these measurements indicate the presence of leakage.

When the results from the mathematical model do not match the automatically recorded measurements an error or an abnormal event is happening, and different scenarios are sought; for example, the pressure sensor may be disconnected, a leak is present, an illegal connection or a disturbance that alters the behavior of fluids within the pipeline.

PhD in Electrical Engineering by the University of Duisburg in Germany, Verde Rodarte, said that the chemical and oil industries, and general processes involving fluid transport systems should have automatic, safe and efficient monitoring in order to avoid accidents with highly volatile fluids or pollutants that cause a great impact on the environment, damage society and the economy. Therefore, her proposal is to place the VIVIUNAM system in control distribution networks to report the presence of disturbances and implementing adequate contingency plans.

In various networks, such as the Cutzamala system, pumping plant Xotepingo (Mexico City) or distribution networks Pemex (Mexican Oil) pipelines have pressure and fluid gauges, however, the data is only used for administrative purposes, instead of take advantage of them to look for leaks and correct the problem, said Cristina Verde.
