Plant Expansion from Reliability Block Diagram study

 Challenge

• Needed to confirm the expected performance of the plant and identify of any significant bottlenecks to the system
• Time constraints (preliminary results desired within 1 week, end results desired ASAP afterwards)
• Limited / approximated information to be used
• Several modelling scenarios required
   

Solution

• Created Reliability Block Diagram (RBD) which could be used to model, at a high system level, projected performance levels and opportunities to improve for existing & expansion facilities.
• Downtime data allocated for the most significant failures & major delays for the respective systems.
• Simple base logic setup to enable easy updates for each design alternative.
• Sensitivity cases run on all desired design alternatives to determine impact on potential production for each case.
• Clear and simple results comparing the outcomes of all design scenarios.
