EnVision’s Simulations: Virtual Operating Experience/Real-Life Skills 

Your trainee operators and engineers need skills that transfer immediately to refinery and petrochemical plant operations.


EnVision’s simulation models are designed to match our tutorials in content and approach. Every model is based on DCS generic instruments and graphic displays. Knowledge transfer is fast and thorough from tutorial to simulation to the real world.

Consistency and Structure…

Simulation training prepares trainees to handle normal operations, startup, shutdown and malfunctions. EnVision’s Simulation Administrator (SimAdmin), a Learning Management System (LMS), tracks their progress.

Support for the Way Your Trainees Learn…

Your operators and engineers learn with your choice of:

  • Training method: Self-paced or instructor-led for multiple trainees in a classroom
  • Implementation: Standalone or Instructor-Trainee mode
  • Content: Simulation only or integrated tutorial & simulation
  • Units: English or metric
  • Languages: English, French, German, Dutch and Spanish


Trainees develop reasoning skills, see cause and effect relationships in action and improve troubleshooting skill
