Gregg Engineering Pipeline Simulation Tools for Transmission Systems

Each segment of the pipeline presents its own unique sets of simulation challenges, and Transmission systems require an application that can accurately model pipelines covering long distances with many variables.

Our suite of core applications and add-on modules will allow you to run your operation from the very beginning of the line all the way to the end of it. Not only will you be able to calculate pressures, flow rates, and a host of other parameters, but also factor in any number of “what ifs” and disruptions that can potentially occur along the way so that your operators can be better prepared for a crisis.

At Gregg Engineering, we have put our team’s experience and actual hands on working knowledge of Transmission systems into designing an entire suite of applications that will help you run your pipeline system from both a hydraulic, as well as a business perspective.

  • Model Creation Tools
    • Create models from GIS (Shapefiles) using the GIS Import tools.
      • Model Repair Tools turn the imported GIS model into a runnable model.
    • Elevations Module – Import elevations into the model for all nodes in the system (NASA database / 90 meter resolution).
    • 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) for faster results.
    • 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).
  • Calibrating and Tuning
    • Reconcile the pressures throughout your entire pipeline system and recalculate efficiencies.
    • Quickly and easily identify areas of a pipeline that most likely have issues which need to be investigated further.
    • Reduce up to 99% of overall system errors in a matter of seconds.
  • Revenue Tracking
    • Model both revenue and expense dollars traveling through the pipeline system for all simulation types.
    • Cumulative revenues and expenses are tracked so that overall profitability over time can be estimated.
  • Integration Tools
    • Import and export data between:
      • Excel
      • Databases (Access, Oracle, SQL Server, etc.).
      • GIS (Shapefiles)
      • SCADA systems (OPC)

Tools for Building and Operating Your Model

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, as well as fill in the blanks of any crucial information which may be missing such as elevations, which can be performed with the click of a button.

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 complex Transmissions systems with multiple service lines, but yet another function which can be performed with ease in our application.

And if your objective is to evaluate the more individual aspects of the pipeline as well as the gas flowing through it, we offer a number of features that will allow you to model those elements as well. With our applications, compressor stations for example can be thoroughly analyzed in order to not only gauge the efficiency of the current units, but also determine the potential requirements for any new purchases as well as.

For any number of reasons you may want to know exactly where the gas is going within your system and where it had come from, which is why we offer a way to create easy to read, color coded models indicating the entire path gas takes from supply point to delivery. Now pipeline operators can also verify the origin of all products traveling through their lines.

We know that operating a pipeline safely all along the line is always a top priority as well, which is why we can partner with you to create a Trainer program which incorporates a Virtual Pipeline Model of your own system into the program. Gas Controllers can be trained, qualified, and prepared for an emergency situation using their own system and daily operating procedures as the testing grounds, right down to the same SCADA HMI that they are accustomed to using on a day-to-day basis.

Determining the System’s Potential

It goes without saying that a pipeline model which has been built with optimum efficiency also stands to become the most profitable as well. This philosophy is why we supply the tools needed to calculate the best possible options and projections for your system, which can then help you determine how to yield the highest rate of return on investment.

Leaks along a pipeline can result from any multitude of factors, both natural as well as mechanical. Given the danger, and financial loss of your product seeping out of its confines, detecting the location of the breech is mission critical, but due to the highly compressible nature of gas, and the mere fact that it is invisible, can be an elusive prospect. With an OnLine system we can compare field data to the values in the model and the discrepancy can then indicate the location of a potential issue.

If you have ever suffered the financial consequences of a sub quality, or a dangerous product infiltrating your network, and the emanate task of tracking it back to the originating source, then you will be interested in learning more about a utility that we offer for tracing your gas or liquid as it had flowed from the point of entry into the system, (including through all the nodes) and out to the very end delivery points. Within our applications you can model all 18 major gas components, and even custom components.

If your task is to evaluate system capacity or required horsepower, assess the potential impact of planned maintenance procedures, or decide whether it makes financial sense to upgrade equipment, wouldn’t you like the ability to run side-by-side comparisons of multiple, alternate scenarios against one another in order to compute the results from all of the variances?  And wouldn’t you like those computations to occur at unprecedented speeds? Well, you can do that with our software.

And how about the capability to model the flow of revenue and expense dollars traveling through the pipeline system in order to estimate the current profitability of the pipeline? Or even better, project the future profitability so you can model revenues and expenses through a winter season, with gas going into or coming out of storage fields as needed. Our software can track revenue and determine which areas of the system are generating the highest yields.

Hydraulic Modeling Meets Business Processes

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.
