Key takeaways
- Obtain representative information for the woodchips actually offered.
- Identify how cargo weight and occupied volume are described and measured.
- Include handling access and receiver requirements in the capacity review.
- Keep final quantity conditional on the owner’s confirmed arrangement.
Define the product and quantity basis
Ask the shipper to identify the woodchips allocated to the shipment, including the product description and relevant transport information. If material from several sources is combined, explain the intended parcel and any requirement to preserve separate lots.
Clarify how the commercial quantity is described and what evidence will establish the shipped amount. Different teams may discuss stock, volume and shipment weight using different bases. Resolve the terminology before comparing a seller’s available quantity with an owner’s intake proposal.

The commercial team should not treat a familiar product name as complete acceptance. Keep the cargo review status separate from the space estimate, especially when the proposed parcel differs from previous shipments in source or description.
Ask which constraint controls the proposal
Weight review and space review should both be visible. The owner may identify usable space as an important constraint for the offered parcel, but the chartering team should obtain that conclusion for the actual vessel rather than assume it universally.
Ask the shipper for representative stowage information and its basis. Is it a measured characteristic of the intended parcel, an estimate from similar material or a planning convention? That distinction tells the owner how much confidence to place in an initial volume assessment.
Request the owner’s intake proposal with the assumptions stated. The figure should relate to the nominated ports, cargo information and proposed arrangement. An intake copied from another voyage can be useful background, but it should not become the new shipment commitment without review.
Where the owner offers a qualified quantity, ask what evidence would make it firmer. The answer may be additional cargo information or a more defined voyage plan. Knowing the missing input is more useful than repeatedly asking for a higher number.
Complete a weight-versus-volume worksheet
| Question | Cargo input | Owner or terminal response | Decision for cargo interests |
|---|---|---|---|
| What is the shipment basis? | Product and quantity definition | Confirmation of the basis used | Reconcile sales and shipping records |
| Could weight limit the lift? | Proposed mass and tolerance | Voyage-specific weight assessment | Confirm a supported parcel amount |
| Could space limit the lift? | Representative stowage information | Usable space assessment | Review vessel or quantity alternatives |
| Is the parcel uniform? | Source and lot information | Arrangement qualifications | Confirm whether separate allocation is needed |
| Can the cargo be handled? | Loading and discharge methods | Access and equipment review | Match vessel choice to the actual facilities |
| What remains uncertain? | Data quality and pending changes | Required evidence and qualifications | Set a final quantity decision point |
Use the worksheet to locate uncertainty before calculating precise outputs. A detailed model built on a poorly defined cargo characteristic can mislead the sales and logistics teams. Preserve source labels and units wherever figures are supplied.
If alternative assumptions are assessed, keep them as separate scenarios. Do not combine the most favorable space estimate with a weight assessment based on another parcel description. The owner’s supported intake should come from one coherent proposal.
Review usable space rather than headline volume
Ask which vessel spaces are relevant to the intended woodchip arrangement and whether any limitations affect their use. The owner should assess access, allocation and technical requirements. The commercial team needs the resulting usable proposal rather than an independent attempt to fill every compartment on paper.
Where different lots or receivers require separation, provide that requirement early. Total volume can look sufficient while the desired lot allocation is awkward or unworkable. The owner should review the actual combination and explain any consequence for intake.
Do not assume residual space is commercially available for another product. An additional parcel changes the arrangement and may introduce new acceptance questions. Obtain review before offering that space to another cargo interest or treating it as evidence that the original quantity can increase.
Connect intake with the loading and receiving systems
Identify the loading method and the discharge facility’s intended operation. Ask the owner and terminal to confirm the interfaces relevant to the nominated ship. A capacity figure has limited value if the cargo cannot be handled through the proposed arrangement.
At destination, ask whether the receiver has a preferred parcel size or intake sequence. A maximum lift may not be the most useful shipment if it creates a receiving problem. Compare the owner’s supported quantity with the receiver’s actual needs before finalizing the commercial amount.
Where the destination or facility is optional, establish the decision deadline and request separate assumptions for realistic alternatives. The owner’s proposal for one receiving arrangement should not be treated as automatically valid for another.
Manage variability through a decision process
If the shipper’s space information has a meaningful range of uncertainty, ask the owner how it affects the planning quantity. The response may remain qualified until the parcel is better defined. Preserve that status in the seller’s allocation and the buyer’s intake plan.
Agree what happens to material beyond the confirmed lift. Can it remain with the shipper, be assigned to a later shipment or be handled through another approved arrangement? A clear commercial fallback reduces pressure to force a larger quantity into the final plan.
Before final nomination, reconcile the cargo description, quantity basis and owner’s intake statement. If any input has changed, obtain a fresh response on the affected point. A short change review is more reliable than assuming the final documents merely formalize the original estimate.
Fictional case: a familiar factor describes the wrong parcel
A fictional woodchip exporter uses a planning factor from an earlier shipment to select a vessel. The new parcel comes from a different allocation, but the commercial worksheet carries the old factor without identifying its source.
The owner requests clarification before confirming intake. The shipper supplies information for the intended material, and the owner revises the space assessment. The exporter then compares a smaller confirmed parcel with another vessel option rather than treating the original estimate as a promised lift.
The exporter also agrees how surplus material will remain allocated if the smaller parcel is selected. The case illustrates why a familiar planning input should retain its provenance. Reusing it can be sensible for early screening, but only if everyone understands that it does not establish the actual parcel’s characteristics.
Common mistakes
Do not prioritize deadweight so strongly that space information becomes an afterthought. Ask the owner which constraint actually controls the intended woodchip parcel and obtain evidence for the assumptions used.
Another mistake is using a cargo volume description without explaining its measurement basis. Resolve different terminology between the seller, terminal and owner before combining their figures in one worksheet.
Avoid committing the seller’s entire available stock before the owner confirms intake. Agree a process for final quantity and surplus material so the cargo interests can plan around a supported figure rather than an optimistic initial screen.

Frequently asked questions
Does a larger deadweight vessel always lift more woodchips?
Not necessarily for a particular shipment. Usable space, the cargo’s characteristics, port conditions and the accepted arrangement all need review. Ask owners for comparable intake proposals using the same parcel information.
What stowage information should the shipper provide?
Provide representative information for the intended material and explain its source and uncertainty. The owner can then assess its relevance to the vessel rather than rely on an unexplained generic factor.
Why agree a surplus-material plan before loading?
The final supported intake may differ from early planning. A clear fallback for unshipped material helps the seller manage allocation and reduces pressure to treat a provisional estimate as an unconditional commitment.
When does an intake proposal need updating?
Update it after material changes in product description, stowage information, quantity basis, lot separation, ports or handling arrangements. Ask the owner to confirm which earlier assumptions remain valid.
