As a basis for comparison, principles and practical aspects of offshore cathodic protection (CP) design have been reviewed. Additionally, a brief presentation of traditional methods for cathodic protection design analysis and cathodic protection criteria are discussed. This paper presents the capabilities of a computer program system for modeling cathodic protection using the Boundary Element Method (BEM).

The program has capabilities for analyzes of dynamic and temporal effects on the level of cathodic protection simultaneously and, predicts the time dependent current density and potential behaviour resulting from the formation of a calcareous deposit.
