The loss of SCADA is an example of which type of AOC?

The loss of SCADA (Supervisory Control and Data Acquisition) is an example of a communications failure because SCADA systems depend on effective communication networks to monitor and control pipeline operations. These systems gather data from field sensors and transmit that information back to control centers, where operators can make real-time decisions and adjustments. If the communication links are disrupted, whether due to network issues, hardware malfunctions, or other related problems, the SCADA system cannot perform its essential functions, leading to a potential loss of control and monitoring capabilities. This directly impacts the overall safety and operational efficiency of the pipeline.

In the context of options like hydraulic failure or power failure, while both can affect the operation of a pipeline, they do not specifically correlate with the loss of SCADA functionality. Mechanical failure refers to the physical breakdown of machinery, which also doesn’t directly address issues related to data communication systems. Therefore, recognizing the role of communication within SCADA systems clarifies why a communications failure is indeed the correct classification in this scenario.
