Life-Cycle / Multi-Purpose Dynamic Simulator (MPDS)


The term Life Cycle simulator (LCS) or Multi-Purpose Dynamic Simulator (MPDS) is the concept of maximising the use of one dynamic process model throughout the design, development and operational phases of a project. Why not use the investment of an Operator Training Simulator to improve the entire development of the process? 

Steady state process simulation has been an industry essential for the development of a process plant for a long time now but the use of a dynamic simulator has many benefits that can not be accounted for at steady state.

Advantages of a life cycle simulator approach include:

  • Reduced Commisioning time and costs from a pre-tested simulation model in the design phases
  • Reduced capital costs through less re-engineering of both equipment and control systems
  • Faster process initial start-up through less comission hiccups and better trained operators
  • Operators trained faster and have in depth knowledge of the system before startup
  • Emergency responses verified and trained on
  • Optimised process
  • Improved safety and reduced risk

Process & Control Verification

  • FEED and Detailed Engineering Dynamic Studies
  • Improvement and validation of process design and control system philosophy
  • Increase the understanding of process interactions and dynamics between process areas.
  • Load balancing, Anti-surge control and Compressor studies
  • Sequence testing (Startup, Shutdown, change over, bypass, etc..)

Safety Analysis

  • Support HAZOP studies
  • Investigate integrity of safety systems
  • Validate shutdown philosophy and logic
  • Test the ability to reset all active shutdowns and start-up the process after a full shutdown
  • Validate the Cause and Effects before implementation.
  • Vigorous blowdown / depressurisation safety studies

DCS/ICSS Checkout

  • Control system verification on the actual control system implementation
  • Improvement and validation of operator graphics
  • Alarm Management
  • Pre-tune PID controllers before startup

Operating Procedures

  • Develop operating procedures before commissioning
  • Test and improve startup overrides
  • Start-up time to normal operation
  • Test interaction required from operator from the DCS to the sequences during startup

Operator Training

  • Realistic training in a safe environment
  • Process startup and shutdown familiarisation and understanding.
  • Process familiarisation including interaction with multiple systems
  • Emergency response training
  • Carry out What-If Scenarios and asses the operator’s response to upsets.
  • Control system training and or refresher courses
  • Navigation around the operator graphics
  • Using the alarm and trend systems
  • Operator assessment and reporting

Operational Support / Debottlenecking studies

  • Test equipment and control system changes
  • Training operators before commissioning of new control changes/equipment.
  • Perform capacity evaluations
  • Advanced process control optimisation
  • End of life studies
  • Planning and profit improvement
