Robust, accurate, proven real-time transient simulator with variable wave-speed and sophisticated air valve and control scheme modelling.
Robust, accurate, proven real-time transient simulator with variable wave-speed and sophisticated air valve and control scheme modelling.
The VariSim Simulator is the result of 50 years of development, refinement and innovation. The resulting highly robust suite of applications and systems now help you simulate and manage every component of a pipeline system with complete confidence.
It is a professional, windows based, pipeline hydraulic simulator product that takes full advantage of today’s computing power and software advancements. It is based upon principals that have been developed, tested and verified within the Hydraulic Analysis Group within a rigorous research and development program. The result is an innovative, fast and reliable product that encapsulates the experience and knowledge within the group and provides the user with an easy to use simulation environment with easily accessible results.
VariSim has a very impressive capability which can be used for detailed steady state and transient hydraulic studies. As a PC based design and planning tool, it is ideal for studying the complexities of any single phase fluid behaviour in pipelines. VariSim has been designed to ensure that it accurately simulates any component of a system that can affect the fluid behaviour. This means, liquid or gas, small plant pipe work, long transmission lines, district heating networks, variable flow regimes, telemetry effects, suppression equipment, air valves, control logic etc. can all be simulated.
Flows, pressures, temperatures or any product information (including composition values in pipes receiving a mix of fluids) can be provided as point values at any location on a pipeline. All control scheme parameters can be accessed and assessed. Inventories of any pipe or zone can be reported in energy or mass terms and equipment operating characteristics can be monitored. Alarms can be generated if you operate outside of your maximum allowable and minimum allowable operating envelope and reports can be generated for post assessment.
VariSim's import capability allows it to create its model from third party sources including other modelling packages and GIS databases. Care has been taken to ensure that VariSims output is easily accessible and easy to understand using industry familiar terminology. This capability and its unique ability to model variable wavepeeds and variable time steps make this product extremely competitive within in its market and we are sure that you will find VariSim commands a challenging position in its industry.
One of VariSim’s major strengths is its ability to offer much more than just PC based simulation. VariSim can become an integral component within the VariSuite framework to create digital and virtual twin environments.
It is a straight forward step to turn VariSim into an online simulator that can be driven by recorded pipeline instrumentation data (flows, pressures, temperatures etc, equipment status etc.). This creates the digital twin to provide a complete picture of the actual pipeline, equipment or network behaviour. If it can be connected via a standard OPC connection to a data acquisition system such as SCADA, this complete picture can be provided in real time.Pipeline Management Applications can be added that operate using output from a VariSim simulator connected to pipeline measurement.
Pipeline Management Applications which include leak detection, capacity management, product and batch tracking etc. provide commercial payback to pipeline operating companies in a matter of months.
Communicating with VariSim is refreshingly simple. When the mode of VariSim is changed from standalone to online or offline, it can communicate with the SSL messaging middleware. Communication with other applications is simply a case of allowing the application to communicate with VariSim via this middleware.
The pipeline simulator is now widely accepted as a key requirement for any operating company that takes its responsibilities seriously. A good simulator helps maximise operational safety, protect the environment and improve the efficiency of operation.
Today, safety is being driven to the highest standards and leaks are being prevented through detailed flow assurance and surge analysis studies.Engineers are conducting analyses to prevent daily operating problems with their pipeline networks and are proactively identifying potential disasters. Steps are being taken to suppress excessive operating pressures, heat distribution and energy usage is being monitored and equipment configuration is being optimised to reduce emissions.
VariSim uses range from simple, steady state determination to simulating complex pressure events. Any operation that can affect the fluid reaction of a pipeline network can be accurately simulated and this includes the plant area.
There is no better way of maximising confidence in the overall system design than being able to simulate the complete interaction between the pipe work, the equipment and the control scheme. Pipework can be correctly sized and rated, control set-points and control parameters can be tuned, system bottlenecks can be identified, storage volumes can be assured and pressure suppression equipment can be correctly sized.

Changes in operation, changes in throughput requirements, deterioration in pipeline and equipment condition or poor initial design can all lead to daily operating problems. VariSim helps identify and solve the source of these problems. Initiation of the simulator with current operating conditions also reveals a wealth of unrealised information for assessment and further simulation.
Planners can assess the effects of future maintenance; operators can quickly establish new procedures without compromising safety and daily nominations can be verified through forecasting and allocated with confidence.
VariSim has been designed to ensure that it accurately models any component of a system that can affect the fluid behaviour within a pipeline. This means small plant pipe work, long transmission lines, variable flow regimes, telemetry effects, surge suppression equipment, control logic etc. can all be accurately simulated. Care has been taken to ensure the VariSim output is easily accessible and easy to understand using industry familiar terminology.
The ability to simulate variable product properties, variable wave-speeds and variable time steps makes VariSim one of the most accurate products on the market.
