Tank Turnover at 58% tank utilization: a worked example

This worked example runs the tank turnover numbers for a tougher week than the baseline: 58% tank utilization instead of the typical 80%. Calculate tank turnover rate from volume processed per shift, mixer operating hours, and tank utilization to plan throughput per vessel.

The inputs for this scenario

  • Volume processed per shift: 2,400 gal (held at the documented default)
  • Mixer operating hours: 8 hr (held at the documented default)
  • Tank utilization: 58 % (the input this scenario stresses; the baseline uses 80)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw tank turnover = volume processed per shift รท mixer operating hours.
  • Effective throughput works out to 174 turns / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 300 turns / hr at these inputs.
  • Efficiency works out to 58 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where tank utilization sits at 80% and the headline result is 240 turns / hr, this scenario comes in 27.5% below the baseline at 174 turns / hr.
  • Use it when balancing a blending line, justifying a larger or second tank, or diagnosing whether a vessel can keep up with downstream fill rates. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Effective throughput: 174 turns / hr (headline result)
  • Raw throughput: 300 turns / hr
  • Efficiency: 58 %
  • Runtime: 8 hr
