Cathodic Protection Numeric Simulation
Cathodic protection monitoring is a most common practice for the assessment of effectiveness of corrosion protection. However, metal loss due to corrosion is somehow evident even on pipes are deemed to be well protected based on standard monitoring and survey techniques. The effectiveness of the the field survey techniques are further questioned for the structures within the common corridor with multiple functioning cathodic protection systems in place. Numeric simulation provides better opportunity to understand the pipe potential as current density along the structure. This, along with standard survey practice, renders a clear picture of the effectiveness of the cathodic protection….
