Sim-On Gas Design

Sim-On™ Gas Design provides an easy, centralized , powerful, fast simulation web platform for approval of new small projects for gas distribution networks.

Sim-On™ Gas Design is a web-based solution that simulates the behaviour of gas distribution networks using pre-defined peak design conditions. It can run any combination of pressure classes – from low to high pressures – simultaneously. It is carefully designed to minimise errors and reduce coordination time between teams in charge of approving new small projects by hosting all their models in a centralised web based modelling platform.

General view of Sim-On Gas Design. It shows a network where some modifications have been tested and some pressure issues have been identified.

How does Sim-On Gas Design work?

Sim-On™ Gas Design works by uploading models built in other desktop modelling applications such as ProBe Gas. It can be made compatible with most of commercial gas modelling software. Once a model is uploaded, Project Planners (with no required modelling experience) can test the impact that future planned projects will have on the network. If eventually approved, these projects will be saved in the system. They will become part of the “official” latest version of the future system. So, they will be included in any subsequent planning approval testing.

Key features

  • A central hub for approval of new projects
    So it facilitates the coordination of different teams and modellers approving new projects in parallel.
  • An easy platform for non-expert modellers to run simple simulations
    the user-friendly and intuitive interface helps bridge the gap between complex hydraulic models and non-expert modellers.
  • A web-based solution
    It works on any device or location. There is no need to install or manage desktop applications. Sim-On™ Gas Design can be used as well as a web visualisation tool to locate assets by the teams on the ground.

What are the main benefits of using Sim-On Gas Design?

Via an easy-to-use web interface, staff in charge of approving new minor projects (such as new connections of small developments) can access an always up-to-date version of the gas network. They can see all past approved projects) and  add new minor changes.  It is then easy to validate the system performance under pre-defined design conditions without the risk of missing the combined effect of previous projects already approved.

Users therefore can:

  • Run simple models without the need of being expert modellers;
  • Be confident that they are using the latest version of the “new projects” network;
  • Be confident that they are always testing under the same design conditions;
  • Work in parallel with other colleagues without fear to miss any changes made by others;
  • Get a quick report informing about the level of service in the system after implementing those proposed new changes;
  • Decide whether a new project is approved or discarded;
  • Leave a clear track of changes of all the projects tested;
  • Export any of the versions tested back to their desktop modelling solution.
Example of quick reporting in Sim-On Gas Design

Using Sim-On Gas Design, non-expert modellers can easily run simple online simulations to look at minor changes in the network. They can:

  • Add demand to existing nodes
  • Add new nodes
  • Move nodes inserted in the current project
  • Add pipes
  • Modify pipelines inserted in the current project
  • Insert regulation stations
  • Insert valves
  • Split existing pipelines with nodes and optionally add demand
  • Split project pipelines with nodes and optionally add demand
  • Cancel a node, conduit, valve or regulator.

Report options

After each simulation, the tool  generates several tabular reports to easily assess the level of service of the network under the new project conditions. Reports can be exported in csv format.

Reports provide a useful insight on the performance of each new project by:

  • Validating minimum pressures and maximum velocities in the system
    Validation can be done simultaneously for different pressure classes.
  • Validating maximum flows through city gates and regulators
    Individual limit values can be defined for each of these elements
  • Validating pressure conditions at regulators
    Individual limit values can be defined for each of these elements
  • Comparing results automatically with previous simulations
    Such as the base scenario (first ever network uploaded) and the antecedent version (version of the last approved project).
