Description: SCADA, communications, and controls are the pipeline’s nerves providing multiple inputs from the pipeline and carrying back control commands. From field instruments, station PLCs or computers, to the control room computers and operator consoles, this module provides a broad overview of the entire control scheme from a practical perspective. Students find the scada video particularly interesting.
The two fundamental types of leak detection, internal and external are discussed along with sensitivity, accuracy, reliability, and robustness – the four key criteria. Key challenges of oil leaks and leak detection versus gas are covered during this module which makes extensive use of hydraulic gradients. This module simplifies and explains what to many is the “black art” of leak detection
