Cryogenic Storage & LNG Equipment worked example

LNG Transfer Loss with lng transfer loss rate of 30 gal / hr: a worked example

What does the result look like when lng transfer loss rate reaches 30 gal / hr? The full calculation is worked below with real intermediate numbers. Use it when lng transfer loss in cryogenic storage and lng equipment is being quoted and consumables are a real chunk of the cost stack.

The inputs for this scenario

  • LNG transfer loss rate: 30 gal / hr (raised for this scenario; the documented default is 12)
  • LNG transfer duration: 8 hr (unchanged)
  • LNG cost basis: 3.5 $ / gal (unchanged)

Working through the calculation

  • Applying the documented formula (Liquid-equivalent LNG lost = LNG transfer loss rate × transfer duration) to the inputs above produces each figure below.
  • At this operating point the engine returns 840 $ for lng transfer loss cost, the number this scenario is built around.
  • At this operating point the engine returns 240 units for liquid-equivalent lng lost.
  • At this operating point the engine returns 8 hr for transfer duration.
  • At this operating point the engine returns 3.5 $ / unit for lng cost basis.

How this compares with the baseline

  • Against the tool's baseline example, where lng transfer loss rate sits at 12 gal / hr and the headline result is 336 $, this scenario comes in 150% above the baseline at 840 $.
  • A figure at this level is achievable when lng transfer loss rate is genuinely sustained, not just peaked for a shift. It assumes a constant hourly loss rate; real boil-off varies with starting temperature, ambient conditions, flow rate, and whether vapor is recovered or vented, so it is an estimate, not a metered measurement.

Results at a glance

  • LNG transfer loss cost: 840 $ (headline result)
  • Liquid-equivalent LNG lost: 240 units
  • Transfer duration: 8 hr
  • LNG cost basis: 3.5 $ / unit
