The cost of troubleshooting CP on pipeline systems can be significantly reduced when gas utilities and pipeline companies locate contacts with foreign metal structures by:

The correct choice relates to the importance of pipeline mapping systems in the context of corrosion control. Properly mapping pipelines allows gas utilities and pipeline companies to identify and document the locations of foreign metal structures that may come into contact with their pipeline systems. Understanding the geographical layout and relationships of these structures aids in anticipating potential corrosion issues that could arise from these interactions.

By having accurate maps, companies can proactively manage and mitigate the risks of corrosion from stray electrical currents or galvanic interactions between dissimilar metals. Effective pipeline mapping enhances the reliability of cathodic protection systems, making it easier to maintain integrity and extend the lifecycle of pipeline assets. Additionally, knowing where foreign structures are located means that resources can be allocated more efficiently when addressing corrosion-related issues, thus significantly reducing the overall cost of troubleshooting.

In contrast, while regular maintenance schedules, real-time monitoring technologies, and manual inspections are valuable components of a comprehensive corrosion management strategy, they do not directly facilitate the initial identification of foreign metal contacts as effectively as pipeline mapping systems do.
