This work is devoted to an actual issue of detecting leakages in a system of main oil pipelines. Now it is necessary to pay special attention to the development of the main transport of oil, the prevention of leakages of oil for ecological safety maintenance in the state. There are some systems of detecting leakages: the system of the continuous control of leakproofness of pipe-lines’ segments is based on the registration of acoustic emission (noise), resulting from liquid leakage through end-to-end defect, in the presence of redundant pressure in a pipe; the parametrical system of detecting leakages LeakSpy – is based on an analysis of the profile of pressure and the statistical analysis of the data obtainted. Joint development of Czech company Process Automation Systems and Open Company NPA «VIRARealTime» (Russia) Leak Detection System is also actual. It is based on accurate measurement of pressure and on a statistic estimation of fluctuations of pressure in different points of a pipeline.
