Dynamic Simulation
A dynamic model is a computer-based simulation that is used to study the control and operation of the plant.

We continuously review simulation software and have considerable experience in dynamic modelling with many of the leading simulation packages. However, our preferred modelling package is currently Hysys.Dynamics from AspenTech.

At PlantLife we develop dynamic simulation models of topsides production facilities for the Oil and gas Industry. The models are used to verify the  process design and process control strategy through engineering studies and to replicate the response of the real plant in process operator training systems.

The high fidelity dynamic models we produce for engineering studies contain the detailed process design data to produce realistic responses to process operation and upset.  The models are used by engineers to evaluate the transient performance and produce graphical information indicating the response of the process under study conditions.  They are therefore required to  provide accurate solutions within the operating envelope of the events being studied, but do not necessarily need to operate under all conditions.

 
Operator training models re used by trainee operators to develop their skills.  Training models often extend beyond the scope of the engineering model to include utility systems.  Unlike engineering models, training models have to be more robust for operation under a whole range of conditions. These include start-up, shutdown, shut-in, blow-down and purging as well as normal operation, because any number of states may be reached during training exercises.
