Operators are not only capable of maintaining the data flow to the real-time model, but are also able to perform predictive model runs, normally without the assistance of simulation engineers...

... is to provide an accurate representation of current and future pipeline operation. To verify the continuous accuracy of the real-time and predictive models, calculated results are compared to SCADA measurements. Confidence in the models capabilities is achieved only when the different application models yield...

Shortly thereafter, the first version of an operational real-time state finder, a look-ahead model and a predictive model were demonstrated. The second portion of the network has been configured and all modules are fully operational. The rest...
