In order to make a practical application of boundary element method (BEM) to quantative predictions of catholic protection and macro-cell corrosion, a BEM analysis system based on the programs for 2D, 3D and axi-symmetric regions was developed. The system consists of a polarization curve database and programs to perform element discretization, input file set up, BE analysis and graphic display of input and output data. Even an engineer with no knowledge of corrosion will be able to easily operate this system and perform effective analyses for optional 3D regions. The usefulness of the system is demonstrated by an application example for the cathodic protection design of a seawater pump. In the system, the effect of flow-rate and time on the polarization curve can be taken into account for defining the boundary conditions.
