Carbon Capture & CO₂ Compression Equipment worked example

Module Assembly Labor at 7.2% fit-up and inspection allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop fit-up and inspection allowance to 7.2%, then walk the calculation through step by step. Estimate labor time required to assemble carbon capture modules, compressor skids, frames, piping, instrumentation, or packaged gas-handling equipment.

The inputs for this scenario

  • Modules or skids to assemble: 120 modules (held at the documented default)
  • Assembly completion rate: 12 modules / min (held at the documented default)
  • Fit-up and inspection allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base assembly labor time = modules or skids to assemble ÷ assembly completion rate.
  • Total module assembly labor time works out to 10.72 min at these inputs, and this is the headline figure for the scenario.
  • Base assembly labor time works out to 10 min at these inputs.
  • Fit-up and inspection allowance works out to 7.2 % at these inputs.
  • Assembly completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fit-up and inspection allowance sits at 10% and the headline result is 11 min, this scenario comes in 2.55% below the baseline at 10.72 min.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to fit-up and inspection allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. A single completion rate assumes every module is comparable; a one-off compression train and a repeat absorber skid have very different per-unit times, so split mixed batches.

Results at a glance

  • Total module assembly labor time: 10.72 min (headline result)
  • Base assembly labor time: 10 min
  • Fit-up and inspection allowance: 7.2 %
  • Assembly completion rate: 12 pieces / min
