Cryogenic Storage & LNG Equipment worked example

Cryogenic Weld Inspection Energy Load with inspection equipment connected load of 30 kW: a worked example

This scenario runs the cryogenic weld inspection energy load calculation on the strong side: inspection equipment connected load of 30 kW, with every other input held at its documented default. Use it when cryogenic weld inspection energy load in cryogenic storage and lng equipment is being quoted and energy is a real chunk of the cryogenic storage and lng equipment cost stack.

The inputs for this scenario

  • Inspection equipment connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Weld inspection runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Welds or weld inches inspected: 1,000 welds or in (unchanged)

Working through the calculation

  • Applying the documented formula (Inspection energy used = inspection equipment connected load × weld inspection runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for inspection energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for weld inspection energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per weld inspected.
  • At this operating point the engine returns 3.6 $ / hr for hourly weld inspection energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where inspection equipment connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • Use it when costing an NDE campaign, allocating utility overhead to a fabrication job, or comparing inspection methods by energy intensity. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Inspection energy used: 240 kWh (headline result)
  • Weld inspection energy cost: 28.8 $
