Abstract

When designing pipelines intended for operation in Arctic conditions, in addition to the use of traditional reliability criteria, it is proposed to take into account the ability of the structure to resist damage and the development of local failures into a global accident, which in technology is called « robustness». The article uses the Monte-Carlo method to assess the robustness of an offshore pipeline operating in Arctic conditions with long periods of autonomy to the effects of internal corrosion. The degree of influence of the parameters of technical and organizational safety barriers on the values of robustness criteria is determined.
