Abstract: A system, apparatus, and method for analyzing cathodic protection (CP) current shielding of a coating are provided. The system includes: a test cell configured to have a coating film disposed therein and to be filled with electrically conductive solution surrounding the coating film; an electrical resistance (ER) probe mounted through a port of the test cell; and a potentiostat configured to: apply potential to the test cell to thereby polarize a sensing element of the ER probe such that the ER probe is configured to measure data indicative of a corrosion rate of the sensing element when the coating film is disposed within the test cell and while a CP current flows through the sensing element; and measure a current density through the sensing element in order to indicate an extent of CP current shielding of the coating film.

Abstract: The present disclosure describes a computer-implemented method that includes: determining a category of a buried pipeline based on a compatibility with cathodic protection and a setup status of the buried pipeline, wherein the buried pipeline includes an external coating on an exterior surface of the buried pipeline; accessing input data from one or more inspection tools, wherein the one or more inspection tools are configured to monitor respective operating conditions of the buried pipeline; analyzing the input data from the one or more inspection tools in a manner specific to the determined category of the buried pipeline; and determining a prioritization schedule to maintain the external coating on the exterior surface of the buried pipeline.
