Introduction to SCADA, Controls, and Leak Detection
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 class provides a broad overview of the entire control scheme from a practical perspective.
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 class simplifies and explains what to many is the “black art” of leak detection.
Students are expected to gain an overview of scada, controls, and leak detection along with understanding how these technologies are used by central control room and field operators to operate oil and gas pipelines. Topics include:
• Overview of scada
• Field devices and their role in controls
• Scada components
• Scada design decisions
• Scada operating decisions
• Scada performance measures
• Communication schemes
• Scada applications
• Scada tools
• Alarms and alarm management
• Local station scada
• Suggested standards and recommended practices
• Leak detection criteria
• Leak detection considerations
• Parameter deviation
• Parameter change
• Line balance
• Real time transient modeling
• Statistical analysis
• Pressure wave analysis
• External leak detection
• Leak detection examples
Learners who successfully complete this course will receive a certificate of completion for 1.0 professional development hours.
This class is taught by Tom Miesner, an oil and gas pipeline veteran who has spent many years in both oil and gas control rooms and oversaw the complete replacement of a scada project which did not go well which caused him to delve into both scada and leak detection. The class is intended for those who want to understand the basics of scada, controls, and leak detection. Attendees of the instructor led class regularly say this class provides them a fundamental understanding of these topics.
The intended audience for this class includes:
• Pipeline technical employees who are new to oil and gas pipelines
• Pipeline control room operators just starting their training
• Pipeline engineering company and contractor design personnel who need to understand the basics of control schemes and hydraulic tools
• Pipeline support personnel such as those in accounting, finance, HR, legal, supply chain, and risk management functions
• Scada and IT vendors who use control room information or supply systems
• Outside attorneys
• Legislatures and regulators
• Members of the public who want to learn more about energy pipelines
