Port, Crane & Terminal Equipment worked example

FAT Workload with fat test rig connected load of 6 kW: a worked example in port, crane & terminal equipment

Suppose fat test rig connected load falls to 6 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate fat workload for port, crane and terminal equipment using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • FAT test rig connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • FAT test runtime: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Units processed during the FAT run: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total fat workload energy cost = fat workload connected load × fat workload runtime × blended electricity rate.
  • Fat workload energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total fat workload energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly fat workload energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fat test rig connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • It computes the kWh a FAT run consumes and converts that into total energy cost and an energy cost spread across the units tested. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
