This project concerns an oil pipeline in Qatar. From a common source tie-in, the pipeline supplies two locations at distances of 5.77 km and 6.76 km, via 8” and 16” pipes respectively. The maximum design pressure is 18.3 barg, and there is to be no cavitation.
Emergency Shutdown Valves are located at various locations in the pipeline. The customer needed to know how to optimize the speed and sequence of valve closure in order to:
- Reduce fire risk
- Reduce pressure surges
- Prevent cavitation
