Port, Crane & Terminal Equipment worked example

Field Commissioning Cost at 54% on-site productive time: a worked example in port, crane & terminal equipment

Here is what the math looks like when conditions slip. We hold every other input steady and drop on-site productive time to 54%, then walk the calculation through step by step. Estimate field commissioning cost for a port crane from on-site hours, the loaded field labor rate, and realized productive time.

The inputs for this scenario

  • On-site commissioning hours: 320 hr (held at the documented default)
  • Loaded field technician rate: 145 $/hr (held at the documented default)
  • On-site productive time: 54 % (the input this scenario stresses; the baseline uses 75)
  • Mobilization and tooling cost: 18,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Commissioning cost = field hours x loaded rate x productive time% + mobilization.
  • Total field commissioning cost works out to 43,056 $ at these inputs, and this is the headline figure for the scenario.
  • Field commissioning cost per unit works out to 135 $ / piece at these inputs.
  • Variable field commissioning cost works out to 25,056 $ at these inputs.
  • Fixed field commissioning cost adder works out to 18,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where on-site productive time sits at 75% and the headline result is 52,800 $, this scenario comes in 18.45% below the baseline at 43,056 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to on-site productive time, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The productive-time factor is a blended assumption; a single storm week or blocked quay access can drop real productivity well below the entered percentage.
