Simulation

We develop our models based on direct plant data – including technical drawings, isometrics, data sheets, as well as live plant operating data – to make sure the model reflects reality.

We carry all the necessary software licences to support our activities. The software we use includes:

  • DynSim
  • HYSYS Dynamics
  • Aspen Plus
  • Pro II
  • AFT Arrow and Fathom
  • Aspen Flare Analyser
  • Caesar II

Dynamic Simulation

Dynamic simulation is a growth area and has already shown significant benefits, with tools such as Hysys and Dynsim being used across a range of industries.  Having your own high fidelity dynamic models allows you to test your control and trip systems, troubleshoot your plant or optimise designs. We can also use dynamic simulation to demonstrate that your relief and flare systems are adequately sized, which may save you considerable capital investment – and make sure the money spent is targeted on the right things. We can also help you with the design of a training simulator that looks and responds like your process that you can use to train your operators quickly and get them better prepared for the unexpected.

We also support our dynamic simulations with steady state and hydraulic network models, to give you confidence in the accuracy and reliability of our results.

Steady State Simulation

We can produce an accurate heat and mass balance of your process, allowing you to better understand its operation and then improve yield and efficiency. With this information, your new designs will be more accurate, saving you project time and reducing the risk.

Hydraulic Network Models

We can build network incompressible or compressible models of your liquid and gas distribution systems, such as a natural gas distribution network or a flare system to demonstrate that it is all correctly designed.

Mechanical Stress Modelling

We have the in-house expertise to make sure your pipework and supports can handle the loads they will face, whether that’s for standard operation or transient emergency scenarios. If needed, we can design any modifications that are required, and use our modelling ability to ensure our designs meet all relevant codes, so that our recommendations meet your every requirement.

In all cases, we are happy to provide advice and make practical recommendations on areas that you need to improve. If you’d like to know more, please get in touch.

Dynamic simulation

A dynamic simulation is a computer model of your process that calculates the real-time operating conditions using industry standard thermodynamic equations and rigorous plant design data. It can accurately predict the effects disturbances will have on your process, and so it is extremely useful as a design tool, as well as analysis of major events. To see what we mean, please watch our case study videos.

Steady State Simulation

Steady State Simulation refers to computer models which converge your plant data using established thermodynamic equations. As the name implies, they are used to model the steady state conditions of a plant, and so they are very useful tools for process design.

Hydraulic Network Models

Hydraulic Network Models are used to calculate the pressure distribution and fluid conditions across complex systems. They can accurately model the effects of pressure and temperature on the fluid properties, and can help to identify trouble spots of high pressure loss. For this reason, they are very useful for flow assurance, as well as pressure relief piping design.
