Advances in offshore cathodic protection modeling using the boundary element method

Abstract

Principles and practical aspects of offshore cathodic protection (CP) design have been reviewed for comparison. Additionally, a brief presentation of traditional methods for CP design design analysis and CP criteria are discussed. This paper presents the capabilities of a computer program system for modelling CP using the Boundary Element Method (BEM). The program has capabilities for analyses of dynamic and temporal effects on the level of CP simultaneously and predicts the time dependent current density and potential behaviour resulting from the formation of a calcareous deposit.
