Technical Testing and Control in Estimation of Accident Risk

Abstract

Complex estimation of the industrial safety of dangerous objects suggests using of the failure risk index. Current procedures of risk evaluation do not consider technical condition of the object and extent of the object fault. We demonstrate a possibility and necessity of increased use of nondestructive testing (NDT) and technical diagnostics (TD) for estimation of the probability of the accident, consider the requirements to the performance of the risk analysis and chart the ways of developing the considered approaches. Introduction of the new requirements to NDT and TD attributed to the necessity of using quantitative NDT indicators, i.e., the reliable data on the size of defects and errors of measurements, and expediency of using the probabilistic methodology of the fracture mechanics is demonstrated for estimation of the real probability of the accident.
