Cryogenic Storage & LNG Equipment worked example

Cryogenic Rework Cost at 58% share of reviewed items expected to need rework: a worked example

Suppose share of reviewed items expected to need rework falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate cost exposure for reworking cryogenic vessels, welds, insulation, piping, or LNG equipment before shipment or commissioning.

The inputs for this scenario

  • Cryogenic items flagged for review: 100 items (held at the documented default)
  • Rework cost per affected cryogenic item: 45 $ / item (held at the documented default)
  • Share of reviewed items expected to need rework: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed retest and re-certification adder: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable rework cost = reviewed cryogenic items × rework cost per item × expected rework share.
  • Total cryogenic rework cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per reviewed item works out to 28.6 $ / piece at these inputs.
  • Variable rework cost works out to 2,610 $ at these inputs.
  • Fixed retest or quality adder works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of reviewed items expected to need rework sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes total rework cost as flagged items times per-item rework cost times the rework share, plus a fixed retest or quality adder. 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.

Results at a glance

  • Total cryogenic rework cost: 2,860 $ (headline result)
  • Rework cost per reviewed item: 28.6 $ / piece
  • Variable rework cost: 2,610 $
  • Fixed retest or quality adder: 250 $
