Abstract: To study the vulnerability of the natural gas pipeline infrastructure in a region of Argentina, the characterization of gas pipelines from the province of Córdoba is carried out in this work. For this purpose, parameters and value intervals that delimit the vulnerability assessment are defined. The following risk issues associated with pipelines are taken into account: a) third-party damage, b) external corrosion, and c) operation conditions that differ from those defined in the pipeline design.The first part of this work presents a survey of main data from the existing gas pipeline network of the province of Córdoba and also of new pipelines that are to be constructed by the government of Córdoba during the triennium 2017-2019. The second part deals with the qualitative risk assessment of the pipeline network under analysis, using the survey data. The proposed qualitative risk assessment determines the probability and the consequences of events that likely occur in the network. The qualitative methodology uses indexes to compare the relative risk of different sections of the network and consequently, pipeline sections that require vulnerability assessments can be determined. Keywords: gas pipelines, characterization, threat, risk, vulnerability. (¹) Profesor Titular, Departamento de Estructuras.
