“Create an event tree for a pipeline leak with leak detection, remote isolation, and ignition prevention barriers, ending in contained release, jet fire, large release, or uncontrolled release.”
Comprenez les décisions qui le sous-tendent.
Alarm response must occur before remote isolation can be effective.
Closing the line limits release size.
Preserve an ignition branch only while material is still released.
Use for a high-level leak-response review before performing detailed dispersion or consequence modelling.
Questions fréquentes
What is the initiating event here?
The initiating event is a pipeline leak, expressed with a frequency before any barrier succeeds or fails.
Why is isolation after detection?
Detection identifies the event and triggers the response that allows remote isolation to close the line.
Can I add more barriers?
Yes. Add barriers such as emergency response, deluge or evacuation in the order they influence the scenario.
