How do we measure utilization and productivity?
Graphic Version
Utilization is throughput/capacity expressed as a percentage
Utilization is strongly affected by the timing of capacity additions versus demand growth Low utilization may signal low productivity, loss of demand, or reserve capacity High utilization...Critical Capacity Assumptions: Example
Graphic Version
Assumptions and rules of thumb
Maximum annual TEU slot turnover = 70 turns (5 day dwell, 350 days/yr) Crane available 16 hours/day (two shifts), 250 days/yr Modern crane maximum = 35 moves/hr Vessel spacing at berth = vessel beam...Container Yard Capacity
Graphic Version
Container yard capacity depends on acreage and storage density
Lower storage densities usually mean less handling and lower cost Terminal designers and managers “densify” to accommodate rising volume...
How do we measure port capacity?
Graphic Version
Capacity may be based on port/terminal estimates, third-party estimates, or engineering studies
Bulk, container, and inland ports may have different capacity metrics and concerns
Near-term throughput capacity may be limited by one or more factors,...
