Frequency Analysis of Failures of Reservoirs at Low Temperatures

The principal focus of the article is on a scenario-type approach to the solution of problems in the identification of dangers and evaluation of the failure probabilities based on an analysis and systematic treatment of statistical data on failures at reservoirs at low environmental temperatures using an event tree method and a fault tree method. The principal advantage of the two methods is that they make it possible to find the most critical variant for the development of events and to find the anticipated risk of failures.
