“
The real world is dynamic
”
Dynamic process simulations analyse the response in variables like pressure, temperature and flow rate during transients that could be caused by:
- Variations in the boundaries – rate, temperature, pressure and composition
- Fault situations – trips and leakage
- Operational problems
- Procedures – start-ups / shutdowns
The simulations may contribute to process design and verify design or result in redesign of:
- Compression systems
- Sea and firewater systems
- Water injection systems
- Control strategies
- Parameter tuning
- Procedures (Start-up, shutdown and trip)
- Choke collapse scenarios
- Safety systems e.g. flare system
Dynamic process simulations are performed using advanced software tools and are performed both in the design phases as well as in the operational phases.
Typical scope of work
- Design of new systems
- Verification of systems
- Analyses of new operating conditions
- Analyses for new rules and regulations
- Trouble shooting on operational issues
- Technical audits and Consultancy services
