Abstract

Prediction of the condition of a structure subject to corrosion based on inverse analysis E. Santana Diaz, R. Adey & J . Baynham Computational Mechanics BEASY, UK Abstract Damages appea on a hull of a vessel during its lifetime. In many cases the exact position of this damage are completely unknown. Its knowledge is important from mainly two points of view. 1. Cathodic protection of the vessel. A corroded hull would be economically inefficient (current and fuel consumption) apart from being potentially dangerous since it is a hot point for crack corrosion. 2. Signature of the vessel. A vessel can be detected from its surrounding electric and magnetic fields. In typical CP systems the designer knows the source of current (the anodes) but does not have a clear knowledge of where the current goes (the cathode) as this depends upon the condition of the metallic surfaces etc. In this paper a method is presented to determine where the current goes from the anodes and hence predict the general condi
