Elsyca V-PIMS Reveals Pipeline Corrosion Mechanisms

The common approach for safe pipeline operation is to include external corrosion direct assessment (ECDA) methodology in the company’s pipeline integrity program. The process relies mainly on field data that is  sometimes impossible to obtain or difficult to evaluate. Elsyca V-PIMS uses in-house developed mechanistic models that provide a 3-D cathodic protection current and potential distribution over the entire pipeline network.    The current demand of individual pipeline sections is determined by the soil corrosivity and coating condition. By integrating soil maps with CP operational settings and available field data, a calibration of the model
