Port, Crane & Terminal Equipment worked example

FAT Workload with fat test rig connected load of 30 kW: a worked example in port, crane & terminal equipment

What does the result look like when fat test rig connected load reaches 30 kW? The full calculation is worked below with real intermediate numbers. Use it when fat workload in port, crane and terminal equipment is being quoted and energy is a real chunk of the port, crane and terminal equipment cost stack.

The inputs for this scenario

  • FAT test rig connected load: 30 kW (raised for this scenario; the documented default is 12)
  • FAT test runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Units processed during the FAT run: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total fat workload energy cost = fat workload connected load × fat workload runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for fat workload energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total fat workload energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly fat workload energy cost.

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 150% above the baseline at 240 kWh.
  • A figure at this level is achievable when fat test rig connected load is genuinely sustained, not just peaked for a shift. It uses a flat connected load, so it overstates energy for tests that idle between motion cycles and understates peaks under full regenerative load.

Results at a glance

  • Fat workload energy used: 240 kWh (headline result)
  • Total fat workload energy cost: 28.8 $
  • Energy cost per kWh: 0.03 $ / piece
  • Hourly fat workload energy cost: 3.6 $ / hr
