Abstract
The system and method of the present application improve pipeline integrity and may optimize operational efficiencies. Using the data that is generated by cathodic protection and pipeline integrity monitoring devices (e.g. rectifier monitoring), the present application utilizes data analytics techniques, such as artificial intelligence and machine learning algorithms, to improve pipeline integrity operations.
