- Date
- Component involved
- pipe (generic)
- Failure mode
- internal explosion
- Initiating cause
- run-away reaction
- Root CAUSE analysis
The initiating casue of the rupture was due to water in the feed crude oil, which changed the composition of the gas mixture and induced an excessive reaction and an unusual rise in pressure.
