Metallic pipelines are facilities that are used to transport of liquid and gaseous hydrocarbons from the exploration and exploitation of oil field concession companies. According to the area of exploration and exploitation of hydrocarbons, they are classified as onshore pipelines or submarine pipelines (offshore) and depending on the product they transport they are called oil pipelines (transportation of crude oil) or gas pipelines (transportation of gas). The main problem identified in the transportation by offshore oil pipelines and gas pipelines is the product leakage caused by the action of typical failure mechanisms not identified and managed on time, being an obligation to implement risk assessment methodologies as established by national regulations (DS 081-2007-EM, RCD 240-2010-OS / CD) and international regulations (ASME B31.8S, API 1160 and DNVGL-RP-F116). Due to this, the present work studies the application of the analytic hierarchy process (AHP) method in risk assessment in offshore pipelines, reducing the of subjectivity in determining the probability of failure and its consequences through the formulation and resolution matrix mathematics, processing: statistical information, specialized industry references and characteristics of three offshore pipelines (one oil pipeline and two gas pipelines). The failure mechanisms analyzed were adapted from the DNVGL-RP-F116 standard for the evaluation of offshore pipelines, which identifies 6 categories, based on the data obtained from the three offshore pipelines of the analysis unit. The average variation of the relative risk between the three offshore pipelines of the unit of analysis, was analyzed with respect to the statistical report of failures in the period 2018-2020, comparing the result obtained by applying the semi-quantitative methodology of Index (IM) and the AHP methodology applied in the calculation of the probability of failure of the present investigation. Finally, it was determined that the risk assessment of offshore pipelines by calculating the probability of failure in pipelines based on the AHP methodology improves by 84% compared with the initial risk and with respect to the statistical report of failures in the unit of analysis.
