Graph showing Pressure at Pumping Facility and Leak Side

SwRI engineers use transient simulations to predict the effect of a leak on the system pressure as a function of time.

Graph Showing Pressure-over-Time Effects

Pipeline simulations are able to predict pressure fluctuations at chosen sensor locations in order to evaluate if the sensors will be able to adequately detect the leak.

SwRI’s in-house tool, TAPS, and commercial software compared against leak data

Pipeline simulations are used to verify if a leak detection system is properly selected and appropriately placed along a pipeline. SwRI performs pipeline simulations to characterize the effect of a leak on the pipeline network, in particular analyzing the change in pressure and flow at the location of the sensors.

Leak detection studies focus on:

  • Selection of the appropriate location for the emergency flow restriction devices (EFRD)
  • Calculation of possible spill volumes
  • Verifying compliance with ASME 31.4/CFR49
  • Pressure transient predictions and emergency response sequences

Field troubleshooting and benchmarking services can also be provided.
