  • Import models from MDB files.
• State of the art Run Engine
  • Over 30 years of upgrades, enhancements, and improvements.
  • Most stable Steady State Run Engine on the market – can solve highly networked systems other simulators can’t.
  • Capable of quickly solving very large systems (1,000,000+ nodes/legs).
• Scenario Manager and MultiScenario Runs
  • Easily create multiple working variations of the simulation model (scenarios) interactively.
  • Auto create scenarios from Excel spreadsheets.
  • Import/update scenario data from spreadsheets.
  • Run multiple scenarios (simulations) in parallel (MultiScenario Run).
  • Compare scenarios with comparison tools, and easily switch between scenarios.
  • Scenarios are synchronized so that when new facilities are added to the model, all scenarios are updated (as opposed to having to add the new facilities to every working copy of the model).

• Loads Planning
  • Interactively modify set points and make simulation runs.
    • Easy to use interface for training operators.
    • Scenarios can be set up as training exercises.
  • AutoTune Module / Efficiency Tuning
    • Given a set of average loads and pressures, automatically derive pipeline efficiencies throughout the system.
  • AutoTune Module / Loads Tuning
    • Given last month’s loads and pressures, and a subset of today’s pressures, automatically estimate today’s loads throughout the system on a per node/meter basis.
  • Loads Planning Module / Load Loss Prediction
    • Given a set of conditions or facility outages that are causing deliverability problems, this feature will predict what loads will be lost if no action is taken.
  • Loads Planning Module / Preemptive Load Planning
    • Given individual load priorities, determines what individual loads could be shut in to alleviate deliverability problems. Optimized to minimize loads lost.
  • Loads Planning Module / Preemptive Zone Load Planning
    • Determines what isolation zones can be shut in to alleviate deliverability problems. Optimized to minimize loads lost.

• Loads Forecasting
  • Forecast potential demands on you gas pipeline systems based on historical consumption and data such as weather, day of the week, holidays, or essentially any type of statistical information.
    • Anticipate peak load requirements in order to make more informed supply purchases and operational decisions.
    • Schedule maintenance or expansion projects when they will have the lowest impact on profitability.
  • Perform analyses to account for a multitude of transient conditional changes in the supply and demand of a pipeline system.
  • Perform short, medium and long term forecasting.
  • Sophisticated internal forecasting engine employs a combination of neural networks, regression and genetic algorithms to statistically learn your data.

• Integration Tools
  • Import and export data between:
    • Excel
    • Databases (Access, Oracle, SQL Server, etc.).
    • GIS
    • SCADA systems (OPC)

The most sophisticated tools for running your simulation are nothing if the model hasn’t been constructed upon a sound foundation. This is why we have created an array of functionalities to create models from data that you already have, such as importing configurations originating from a GIS system, to supplying additional build tools such as Google Maps, which will allow you to view your system on top of its actual terrain with such detail that you will be able to see where shut off valves are actually located.

Traditionally, calibrating a model to more accurately reflect the real world working conditions of the actual pipeline has been performed by modifying the individual efficiencies in the various pipe segments. This method can be an incredibly time consuming challenge for highly networked Distribution systems with thousands of service lines where there is potential for missed connections. Luckily, tuning your model is yet another function which can be performed with ease in our application.

And as an LDC your objective is to consistently meet the demands of your customers while maintaining the Integrity of your system. The best way to do this is by being strategic in your planning and purchasing decisions in order to strike the fine balance between enough, but no too much, nor be blindsided by a significant spike or event that you wish you’d seen coming.

But this type of foresight is only possible if you could have a reasonable expectation of what your customer’s usage will be. We have developed a suite of applications to help LDCs anticipate load requirements based on almost any type of parameters that you would like to configure your analysis upon, such as historical data, holidays, temperature, day of the week, local events, etc. The generated results can span anywhere from broad profiles to detailed hourly consumption rates. Now you can forecast tomorrows demand by utilizing yesterday’s data. Every business should be so fortunate as to have tools like this at their disposal.

Sometimes, despite all of your efforts to ensure adequate supply in your lines, things happen that can prevent you from delivering it. And when they do, you have to act quickly in order to handle the situation and mitigate the disruption. We can help you address those types of events in order to be better prepared and ensure that all delivery locations stay above their respective minimum pressures, as well as predict load losses during cases of outages or other emergency situations. Our load planning module allows multiple levels of insight and control when any type of low pressure situation is encountered. After all, the one thing standing between you and a five star customer service rating could be your ability to minimize the impact your customer’s experience, especially your higher priority customers.

Advances in technology, such as the software solutions which Gregg Engineering develops, has made the pipeline modeling process much more efficient, faster and far more accurate than anything else available on the market. What’s more, we have designed all of our software to integrate effortlessly with the rest of your business processes by just as easily importing data in, as it does exporting data back out again. We know that it is not sufficient to use simulation technology to just model pipelines, but rather to use it in conjunction with integration and automation tools to help solve business problems on multiple levels. This type of intel is critically important for a company to remain competitive and profitable.
