Key takeaways

  • Distinguish incoming material forecasts from finished parcels available for shipment.
  • Keep product mix and buyer requirements inside the employment model.
  • Test shared preparation dependencies before crediting substitute cargoes.
  • Evaluate the cost of maintaining vessel utilization without assuming extra cargo is free.
  • Compare full spot and period service boundaries under the actual terms.

Build the base programme from outgoing parcels

A collection or purchasing forecast describes material entering the business. The shipping programme concerns the actual parcels leaving it. If preparation, allocation or qualified review stands between those stages, the model should show that dependency rather than treating incoming tonnes as immediately employable cargo.

ReMA's specifications support trading descriptions for processed scrap. ReMA specifications overview.

Use the actual agreed product requirements and supported output for the intended sales. A broad scrap total can contain material that serves different customers or needs a different preparation path. The vessel proposal should be assessed against the real outgoing cargo mix.

Separate committed parcels, forecast output and possible purchases. Each can inform planning, but they should not have the same status in the supported base case. A decision maker needs to see how much of the longer commitment rests on cargo not yet established.

Identify what the period arrangement would control

A period proposal may offer useful control under its actual terms, but it does not control every part of the supply chain. The buyer should identify which decisions it expects to make and whether the proposed arrangement permits them.

Useful control might concern sequencing supported parcels or responding to an authorized destination choice. It does not make an unfinished lot ready or convert unsuitable material into the product a customer bought. Keep vessel flexibility separate from cargo availability.

Ask what specific event the control would help address. If the next parcel is delayed, is another suitable lot actually available? Does it have a supported receiving path and the relevant commercial rights? Without those conditions, the option remains theoretical.

The spot comparison should be treated with the same care. Read its actual terms rather than assuming it provides no flexibility. Check the current text with appropriate advisers where interpretation is needed.

Test the cost of filling a cargo gap

A team seeking to keep a committed vessel busy may consider buying extra material or accelerating preparation. Evaluate that response as a separate commercial decision. Additional cargo has a product cost and may need further services before it becomes a supported shipment.

Do not credit extra tonnes to utilization while leaving their acquisition or preparation consequences outside the broader business comparison. If the employment decision is transport-only, show the cargo response separately and explain that it is not free work.

The buyer also needs demand for the resulting product. A vessel's available time is not itself a reason to purchase material that lacks a supported sale or receiving outcome. The complete commercial case should connect supply, transport and the buyer's need.

A response may still be worthwhile. The point is to compare its actual incremental cost and value with the exposure of the gap, using supported proposals rather than invented availability or margins.

Use a supply-to-employment table

Programme layerQuestion to resolveEffect on the decision
Incoming materialWhat is purchased or forecast to arrive?Describes potential supply, not yet usable employment
Preparation outputWhat supported product and quantity result?Establishes outgoing cargo availability
Commercial allocationWhich buyer and requirement does the parcel serve?Connects the shipment with real demand
Cargo reviewWhat qualified conclusions and conditions apply?Determines which proposals remain supported
Loading chainWhich services connect the lot to the ship?Exposes shared dependencies
Alternative parcelDoes it avoid the controlling problem?Tests the practical value of substitution
Gap responseWhat additional purchase or service is needed?Reveals the true cost of maintaining utilization
End obligationsWhat remains after the last supported cargo?Completes the employment boundary

The table should distinguish a supported programme from an ambition to use the vessel. A busy-looking calendar is not persuasive if each movement depends on the same unresolved preparation output.

Examine shared constraints across the product mix

Several available scrap purchases may rely on one preparation service or one receiving arrangement. If that common stage is unavailable, the purchases may provide little flexibility for the proposed vessel programme.

Describe the shared dependency and test whether an alternative actually avoids it. A different supplier name does not necessarily create a different path. Conversely, a supported alternative using another suitable service may provide real value.

Do not invent a universal ranking of processed forms or supply sources. Use the actual material descriptions, qualified responses and commercial scopes. The useful question is whether the alternative can perform the required sale and movement under the relevant circumstances.

This analysis helps the buyer avoid paying for control that cannot be exercised. It also identifies where a targeted cargo or service agreement might strengthen the case for a longer vessel commitment.

Compare equivalent complete costs

A spot proposal and a period proposal can allocate services differently under their actual terms. Identify the relevant components before comparing totals. Include supported positioning, transition, gap and completion effects where they belong within the chosen boundary.

Do not assume alternative earnings fill every interval. A separate cargo opportunity needs commercial support, relevant rights and qualified suitability. Keep it conditional until those matters are established, and include the complete transition back to the intended programme.

Also distinguish gross cash needs from ultimate cost allocation if another party may reimburse a component. The employment estimate should not omit a necessary service or count an allocation twice. Use the actual evidence and explain unresolved treatment.

A fictional collection forecast overstates vessel work

In this fictional case, a recycler expects substantial incoming material and considers period vessel employment. Its initial calendar converts the collection forecast directly into outgoing shipments of the product its customers require.

The preparation review shows that the incoming mix does not yet support that sequence. Some material needs additional work, some serves other allocations and some output remains uncertain. The apparently continuous employment programme contains cargo gaps.

The business rebuilds the base case from supported outgoing parcels. It evaluates extra purchases and preparation services as separate responses, including their commercial consequences, and compares the complete period exposure with defined spot movements.

The fictional lesson is that material flow and vessel employment are connected but different. A supply forecast becomes usable work only through a supported product and delivery path.

State the condition that supports the commitment

The final recommendation should explain what makes the preferred arrangement fit: a supported sequence, useful permitted control or an acceptable trade-off between cost and uncertainty. Identify the evidence that would materially weaken or strengthen that conclusion.

Avoid assigning unsupported probabilities to cargo gaps. A clear scenario can show whether the choice depends on optimistic output without pretending to forecast the event. Management can then focus on securing the cargo or service basis that matters.

Common mistakes

Treating collected tonnes as shippable product overstates the employment base. Use supported outgoing parcels and actual buyer requirements.

Another mistake is buying cargo to fill vessel time without evaluating the broader commercial effect. Extra utilization is not automatically extra value.

Finally, do not count alternatives that share the same bottleneck as independent protection. Test whether the proposed response avoids the controlling dependency.

Frequently asked questions

Does a large collection programme justify period employment?

Not automatically. The supported outgoing product sequence and complete commercial responsibilities determine whether the vessel commitment fits.

What should be counted as base employment?

Cargo with sufficiently supported product, allocation, timing and receiving assumptions for the decision. Keep forecast or optional work clearly distinguished.

Can extra purchases solve a vessel gap?

Potentially, but evaluate their acquisition, preparation and sale consequences alongside transport. Do not treat additional material as free employment.

Why examine shared dependencies?

Several parcels can rely on the same unavailable stage. Their number may overstate the practical flexibility of the programme.

What should the final comparison explain?

Supported work, equivalent complete costs, useful control, cargo-gap responses and end obligations, including the assumptions that could change the choice.
