While the chemical process is fairly straight forward the difficulty in simulation and design stems from the approximation of the protective coating effectiveness and degradation, approximation of the corrosion cell, evaluation of the electrolytic media (soil), protective system selection, life cycle cost calculations and
finally the material section with installation details. The inherent complexity involved in each step of the overall process shown in figure 2 represents a technical challenge in approximating partial or highly dynamic data sets, such as soil resistivities across the length of a pipeline. Discipline specific engineers not
only specialized in pipeline design but also in integrating cathodic protection are essential in developing a constructible pipeline system with temporary and permanent cathodic protection that can be installed simultaneously, protected and ready to move product once commissioning is complete.
