Security of pipelines in natural gas distribution network
Transportation Research Procedia, 2019 Abstract A large number of gas facilities across the territory of Slovak Republic could be the target of criminal actions, a lot of them could be easily sabotaged. These facilities are usually located in isolated places (away from the towns and cities), thus making them subject to attacks and violent actions.
