Tank, Vessel & Pressure Equipment Fabrication worked example

Shop Bay Utilization at 99% target bay occupancy rate: a worked example in tank, vessel & pressure equipment fabrication

Push target bay occupancy rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when shop bay utilization in tank, vessel and pressure equipment fabrication needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Fabrication bays currently occupied: 8 bays (unchanged)
  • Total fabrication bays available: 250 bays (unchanged)
  • Target bay occupancy rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Shop Bay Utilization rate = affected amount รท total amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for gap to target.
  • At this operating point the engine returns 8 count for affected count.
  • At this operating point the engine returns 250 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where target bay occupancy rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the ratio of occupied bays to total available bays as a percentage, and the point gap to your target occupancy. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Rate: 3.2 % (headline result)
  • Gap to target: 95.8 points
  • Affected count: 8 count
  • Total count: 250 count

Run it with your numbers

  • Every input above is editable in the live Shop Bay Utilization calculator, which recalculates instantly and can be shared with the inputs intact.
