Abstract

In order to quickly locate the damaged areas of submarine coating without entering the dock. The submarine surface corrosion current is equivalent to a series of point-type current sources, and the submarine underwater corrosion electric field is modeled. Based on Tikhonov regularization, the current intensity of the equivalent point-type current sources is inversed by the measured value of underwater electric field, and the damaged areas of submarine coating are located according to the corrosion current distribution on submarine surface. The validity of the proposed method has been proved through the comparison of the predicted and the practically damaged areas for a test submarine model.
