Abstract

Cathodic protection (CP) is a widely used technique to mitigate corrosion in buried steel pipelines. This study uses COMSOL Multiphysics to model and analyze the performance of both sacrificial anode and impressed current systems in a simulated 3D environment. The model solves for pipeline potential, current density, and corrosion rate within a surrounding soil domain to assess protection coverage across the pipeline. Simulations were conducted to evaluate the influence of electrode and electrolyte properties on CP effectiveness. The study demonstrates that COMSOL Multiphysics is an effective tool for modeling CP systems, offering insights that align with established industry practices. While simplifications such as uniform soil properties and time-independence limit the model's scope, the results provide a strong foundation for future work involving more complex scenarios like with heterogeneous soil composition, coatings, or temperature variation.
