“…In addition, there are problems with inspection techniques and with tools that may be inadequate and susceptible to error and imprecision besides the limitations embedded in these deterministic models. [2][3][4][5][6][7][8][9][10] Hence, a best-estimate assessment of the life of these pipelines that integrates the uncertainties surrounding this estimation is needed.…”

Structural health monitoring enables corrosion fatigue damage for in‐service structures to be evaluated and prognosis health management to perform. In this paper, a Bayesian inference method using random walks is implemented to estimate the reliability of structures such as the pipelines subjected to repeated pressurization cycles and corrosive agents. The proposed method eliminates the intermediate step in updating process and computes the cumulative distribution function instead of calculating probability density function of individual parameters in conventional ones, which is affordable for a routine program, especially convenient for practical engineering use in the field. As taking all relevant random variables into account, this approach could significantly reduce uncertainties associated. For illustration and validation purpose, both numerical and practical examples are demonstrated in details. Copyright © 2016 John Wiley & Sons, Ltd.
