Port, Crane & Terminal Equipment worked example

Downtime Cost at 92% berth schedule recovery shortfall: a worked example in port, crane & terminal equipment

This scenario runs the downtime cost calculation on the strong side: 92% berth schedule recovery shortfall, with every other input held at its documented default. A terminal operations manager quantifies the cost of a 36-hour hoist failure on a single ship-to-shore crane during a vessel call.

The inputs for this scenario

  • Crane out-of-service duration: 36 hr (unchanged)
  • Lost container throughput value per hour: 3,200 $/hr (unchanged)
  • Berth schedule recovery shortfall: 92 % (raised for this scenario; the documented default is 80)
  • Emergency repair call-out charge: 12,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Downtime cost = downtime hours x lost throughput per hour x recovery shortfall% + call-out) to the inputs above produces each figure below.
  • At this operating point the engine returns 117,984 $ for total downtime cost, the number this scenario is built around.
  • At this operating point the engine returns 3,277 $ / piece for downtime cost per unit.
  • At this operating point the engine returns 105,984 $ for variable downtime cost.
  • At this operating point the engine returns 12,000 $ for fixed downtime cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where berth schedule recovery shortfall sits at 80% and the headline result is 104,160 $, this scenario comes in 13.27% above the baseline at 117,984 $.
  • Use it after or during an unplanned outage to size the financial impact, or in planning to justify reliability spend against expected outage costs. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
