In this paper, an effective boundary element method was developed for predicting galvanic corrosion rate for complicated structures. A direct application of conventional numerical procedures to this practical problem causes an increasing of boundary elements. Firstly, a rational criterion for an application of axis-symmetrical elements was proposed. Secondly, a method which analyzes only focused region of a structure was developed. By using these proposed methods, the number of boundary elements is decreased. A example for practical sea water pump is presented to demonstrate the practical applicability of the proposed methods.
