Nowadays, stress corrosion fracturing of hull structures of ships and floating facilities is a matter of concern. Considering the presence of the juvenile surface at the tips of local defects, some adjustment is required for parameters governing protection in the existing methods of protecting against stress corrosion damages. However experimental determination of the juvenile surface for all steels is impossible. This article deals with solving a problem of predicting the protective potential to prevent hull structures of ships and floating facilities against stress corrosion fracturing. The solving is performed by use of a computer assisted data analysis with intermediate prediction of reference parameters such as potential of steel with an oxide film on, and that of steel without any oxide film, for different steel grades and sea water salinities. The suggested approach allows improving quality of protective means of hull structures of ships and floating facilities against stress corrosion damages by stabilizing the cathodic polarization process, providing appropriate potential of the uncharged surface.
