Tank, Vessel & Pressure Equipment Fabrication worked example

Radiography Cost at 92% coverage percentage requiring rt: a worked example

What does the result look like when coverage percentage requiring rt reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when radiography cost in tank, vessel and pressure equipment fabrication is being put through a tank, vessel and pressure equipment fabrication weighted-cost review.

The inputs for this scenario

  • Weld shots or radiographs to expose: 100 shots (unchanged)
  • Cost per radiograph shot: 45 $ / shot (unchanged)
  • Coverage percentage requiring RT: 92 % (raised for this scenario; the documented default is 80)
  • Setup and mobilization fixed cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Radiography Cost cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where coverage percentage requiring rt sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when coverage percentage requiring rt is genuinely sustained, not just peaked for a shift. It assumes a flat per-shot rate and does not separately price re-shoots, digital vs film RT, or crawler versus panoramic exposures, which can shift real cost.

Results at a glance

  • Weighted cost: 4,390 $ (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
