In the safety management in the bottom plate of an oil storage tank, it is important to detect the local corrosion accurately because of its critical phenomenon for preventing a serious accident. Although the discrete measurement of the bottom plate based on the Fire Services Act is carried out, the maximum corrosion depth would not be detected. Therefore, this study is carried out to estimate maximum corrosion depth by using thickness of previous inspection data and Bayesian statistics. As a result, the estimated corrosion depth with the proposed method was good agreement with actual maximum corrosion depth.
