Pipeline Leak Detection Alert
What happens when a pipeline leak detection system spots a possible leak: confirmation, valve closure, field response and regulator notification.
Drawing diagram…
What this diagram shows
- Leak detection compares flow in and out plus pressure drops
- The controller confirms before isolating the segment
- Field crew, emergency services and regulator are notified
Prompt used
Pipeline leak sequence: the computational pipeline monitoring system detects a flow imbalance and pressure drop in segment 7 and alarms the SCADA controller, who checks trends and confirms a probable leak, commands the upstream and downstream block valves to close and stops the pumps, the emergency response plan is activated, the field crew is dispatched to locate the leak, emergency services and the regulator are notified, and repair starts after the segment is made safe.
