Актуальность. Оценка надежности системы газопроводов – одна из наиболее важных задач, поскольку безопасность поставок газа неразрывно связана с надежной работой всей системы в целом.С целью обеспечения заданного уровня надежности газопроводных систем в настоящем исследовании описана методика оценки приемлемого уровня риска, которая устанавливается в соответствии с действующими нормами и стандартами.Методы исследования. Применяется трехкомпонентная методика оценки заданного уровня надежности газопроводных систем. Она реализуется путем создания модели последствий отказа, которая учитывает условия окружающей среды и характеристики газопроводов. Далее определяются приемлемые вероятности отказа трубопровода с помощью теории риска. На основе этих данных создается модель для оценки надежности транспортировки газа в системе газопроводов с учетом вероятности отказа и гидравлических характеристик.Результаты. Определяется заданный уровень надежности системы на основе допустимой вероятности отказа. Полученное значение надежности сравнивается с фактическим уровнем надежности реальной системы газопроводов. Определен оптимальный вариант действий для обеспечения и повышения надежности системы на основе сделанных выводов.

The reliability evaluation of gas pipeline systems is one of the most important tasks, since the safety of gas supplies determines the reliable operation of the whole system.Purpose: This paper presents the evaluation methodology based on the risk acceptance criteria established in accordance with the current rules and standards.Methodology: A three-component methodology is used to evaluate the reliability level of gas pipeline systems. It is implemented by creating a model of failure consequences, which accounts for environmental conditions and pipeline properties. Acceptable probabilities of the pipeline failure are determined using the risk theory. Based on these data, the model is designed to assess the gas transport reliability in the pipeline system with regard to failure probabilities and hydraulic characteristics.Research findings: The reliability level of the system is determined using the acceptable failure probability. The obtained reliability is compared with that of the real pipeline system. The best procedure is proposed to maintain and improve the system reliability.
