Numerical Simulation of Cathodic Protection for Jack-up Platform
For the jack-up platforms huge size and complex structure, as well as the variation and complexity of their ambient corrosion environment, problems often arise in cathodic protection (CP) systems.The rise of the computer and the numerical simulation technology provide a new technical method to the prediction, evaluation and optimization of CP system for jack-up platform.Numerical simulation method has the advantage of examining potential maps of the entire structure easily and then the designer can determine the number and placement of anodes required to provide protection from the under and over protection regions based on a generic polarization response.In this paper the 3-D boundary element method was used to calculate the mathematical model of sacrificial anode CP system for a jack-up platform.Introduced piecewise quasi linearized method to deal with nonlinear problem of boundary conditions.Adopt block boundary element method to solve electrolyte inconsistency problem and points regional modeling to solve electrolyte discontinuous.From the results we can conclude that the jack-up platform sacrificial anode CP system meets the protection targets.
