Cryogenic Storage & LNG Equipment worked example

Field Erection Labor at 12% field delay and handling allowance: a worked example

What does the result look like when field delay and handling allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when field erection labor in cryogenic storage and lng equipment needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Cryogenic equipment erection workload: 120 installed units (unchanged)
  • Field erection completion rate: 12 units / hr (unchanged)
  • Field delay and handling allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base erection labor = cryogenic equipment erection workload รท field erection completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required field erection labor, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base erection labor.
  • At this operating point the engine returns 12 % for field delay allowance applied.
  • At this operating point the engine returns 12 pieces / min for field erection completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where field delay and handling allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when field delay and handling allowance is genuinely sustained, not just peaked for a shift. It uses one blended completion rate, so a job mixing quick pipe-rack sets with a slow cold-box alignment needs to be split into separate runs.

Results at a glance

  • Required field erection labor: 11.2 hr (headline result)
  • Base erection labor: 10 hr
  • Field delay allowance applied: 12 %
  • Field erection completion rate: 12 pieces / min
