Assessment

A capable steady-state and dynamic simulator with a natural home in Honeywell-automated plants and operator training projects.

  1. Capability25%8/10

    Steady-state and dynamic modelling, equation-oriented optimisation, refinery reactors and relief and blowdown studies.

  2. Interoperability20%6/10

    Strongest alongside Honeywell's control and training systems.

  3. Scale15%8/10

    Used for plant design, performance monitoring and operator training simulators.

  4. Usability15%7/10

    Workflows will feel familiar to many process engineers.

  5. Deployment10%6/10

    Primarily desktop software.

  6. Ecosystem15%7/10

    Solid user base, particularly where Honeywell control systems are installed.

Strengths

  • Dynamics for operator training
  • Relief and blowdown studies
  • Honeywell control-system alignment

Considerations

  • Product branding has shifted over time
  • Smaller ecosystem than the market leader
  • Desktop-centred
