The project is dedicated to the modernisation of the main gas pipelines by introducing advanced infrastructure elements. Main gas pipelines (MD) branches to Girininkai, Jonava, N. Akmenė and Palanga Gas Distribution Station (DSS) and MD Panevėžys-Šiauliai II thread were built in 1964-1998. These branches of MD transfer gas to the OSH of Kretinga, Palanga, New Akmenė, Mažeikiai, Papilė, Birštonas, Prienai, Girininkai, Jonava, as well as MD branch Panevėžys-Šiauliai gas supplied to other system users. To date, no internal diagnostics have been carried out on the gas pipelines in question, as MD is not suitable for this purpose. According to the requirements of the Rules for the Operation of the Natural Gas Transmission System, the pipeline is annually inspected, measurements of the integrity of the insulation coating are carried out in order to detect violations of the MD in the event of gas leakage or damage to the coating and the decay of the pipeline. Without the possibility of internal diagnostics, it is not possible to reliably assess the condition of the gas pipeline for further operation. The taps of these pipelines are technologically outdated and leaked. In the event of unforeseen disruptions to the gas transmission system, it would be difficult to properly and expeditiously localise gas leaks or accidents. Thanks to the installation of taps and fittings, it is not possible to miss the monitor and reliably determine the state of the pipeline. During the implementation of the project, six sections of the MD would be equipped with monitor start-up and receiving cameras and operational technological control of the system. These technologies would ensure reliable transmission of gas to the customers of the gas pipelines in question, i.e. improving the quality of the public service and avoiding losses to consumers as a result of the cessation of their economic activities. These advanced elements would also help to manage the flow of natural gas, react promptly to system failures (accidents), thereby reducing emissions and avoiding serious human injuries.
