Using OLGA OTS with a dynamic process simulator in an Operator Training Simulator manifests invaluable benefits.

Engineering and Design:

• Proved valuable for overall engineering and design
• Predicted the production system liquid hold-up volume
• Established robust control structures between pipelines and processing

Control System Checkout:

• Debottlenecked and verified new DCS on OTS prior to start-up
• Tested interaction between subsea and process control systems
• Tested interaction between subsea/process control system and safety system

Operating Procedures:

• Improved and verified operational procedures at OTS
• Planned mechanical pigging frequencies
• Established glycol inventory control
• Determined start-up and ramp-up times and sequences

Commissioning/Start-up:

• Saved months of commissioning time at site by using OTS as test bed for control system and logic
• Ran OTS in parallel to plant throughout first start-up of subsea production system to forecast upcoming dynamics and handling of unexpected events

Operator Training:

• Trained a high number of operators and engineers prior to first gas/oil
• Added hands on experience to control room operators prior to start-up

Operation:

• Increased uptime
• OTS ensured flawless start up of field
• Ensured safer working environment
• Optimised production
• Reduced human errors
