Through the use of dynamic simulation you can - do it right the first time around.

Why wait until commissioning to test and verify the result of a modification to the control strategies? During the commissioning process all stakeholders are under pressure to get the system up and running as soon as possible, which give very few opportunities to test different operating setups.

Optimation has executed numerous projects where process models and simulation were used to test and verify new control strategies. Through our projects we have acquired vast experience in building process models where

  • both the type and complexity have been adapted to the usage and project objective
  • the model has been verified against true conditions
  • the detail level offers a credible simulation result in combination with an acceptable simulation rate

 The work with modelling/simulation and control technology is important in all phases of a project:


All projects will benefit from using modelling and simulation right from the start.

In the early stages of a project, simulation will be useful as the process engineering solutions can still be influenced and therefore offer additional opportunities to utilize the benefits presented by the simulation. The aim is to get an understanding of the process's dynamic behaviour and a good basis for a positive interaction between process and control technology solutions at an early stage. The developed simulation model can also be used at later phases of the project.

Different solution ideas can be examined in the pilot study. In the hands of process engineers the simulator is then a powerful tool that can assess different process engineering solutions and how these can be controlled.

  • Performance of process components
  • Dimensioning motors, pumps, fans etc.
  • Valve sizes
  • Control range
  • Control strategies

 The function description can be supplemented with results from simulations and in doing so provide improved documentation for procurement of the “right” function.

Dynamic Visualisation

By presenting the results of the simulations in animated graphics, such as trend curves, process images and 3D displays, the effects of different solutions can be illustrated in a more effective manner. This means that discussions about the simulation results can be held in a wider forum where insights, ideas and creativity will create a broader understanding that can be applied to the solutions already at the preplanning stage.


The model from the preplanning stage can be further developed and refined and therefore be used in the design work. The simulator acts as a process alternative for development, analysis and testing of:

  • Control strategies.
  • Trimming of control circuits.
  • Interlocking chains.
  • DCS - programs.
  • Operator displays.

 A simulator can also act as a powerful trimming and optimization tool in existing plants with regards to fault tracing and analysis of control systems.


The simulator is a powerful training tool that can be used throughout the entire project. It is particularly useful in operator training as it provides a new dimension and increased understanding of the collaboration between process and control technology solutions. The result of operator actions in slow process stages can be studied more easily through “forcing” the time in the simulator.

Dynamic visualisation is also a powerful tool in combination with training. It can make the simulation results more accessible and create discussions around alternative modes of operation.

Operator Support

Different types of decision data and master controls can be developed using the process model as a basis.

Examples of functions that can be realised:

  • Visualisation of the process state
  • Virtual measurement points
  • Forecasting tools, “what if analysis”
  • Model based control
