To assess corrosion in buried metallic pipelines that are coated and under cathodic protection, an algorithm is proposed. This algorithm that is called "Corrosion Assessment Algorithm" or briefly CAA, can be regarded as a modification of Frank & Morgan risk analysis. By using CAA, one can both calculate the most capital-requiring part of a system and distinguish the technically riskiest subsystems based on their risk factors. CAA can be used to give the highest expecting reliability due to improvement in conditions of a corroding system.
