Case 0001 — Composite case study
Claim family: Quantity, shortage and outturn disputes
Cargo: Bagged rice
Stage: Ship-to-shore quantity reconciliation
Geographical focus: Owendo, Libreville and Gabon trades
The first indication of trouble appeared as a delivery exception describing an apparent discharge shortage affecting bagged rice after ship-to-shore quantity reconciliation. The quantity recorded ashore did not agree with the quantity said to have been shipped, but that first difference was only the beginning of the investigation.
The source material included draft survey worksheets covering only part of the movement, while the source chronology in the bills of lading and mate’s receipts contained a later amendment. The compared figures did not all measure the same stage. There was also no complete, jointly accepted tally connecting the identified rice parcel from the vessel’s holds, across the ship-to-shore transfer point and into the next place of custody.
The survey therefore defined the affected parcel, tested whether a measurement or transcription error existed in one of the compared records, and preserved the information needed to complete a joint tally before the next custody handover. None of those steps required a premature view on liability.
The commercial pressure was immediate. Rice is commonly sold, financed, insured and delivered against documentary quantities. A difference discovered at destination can affect settlement with the seller, payment under the sale contract, the receiver’s stock position, the carrier’s exposure, the terminal’s records and the cargo insurer’s adjustment. If discharge has ended and the cargo is already being moved, stacked, rebagged or distributed, the opportunity to establish where the difference arose can disappear within hours.
The correct first question was therefore not, “Who must pay for the shortage?” It was:
Do the records establish that the same parcel, measured on a consistent basis and across a defined custody boundary, produced a real net shortage?
This composite case examines that question through an apparent bagged rice discharge shortage at Owendo, serving the Libreville market and wider Gabon trade. It is based on recurring claims patterns and has been anonymised and combined for research and training. It does not identify an actual vessel, claimant, receiver or casualty.
Why the exact location within Owendo matters
At Owendo, the rice does not necessarily move directly from the vessel into the receiver’s final warehouse. It may pass from the hold to the ship’s side, through a landing area, onto a truck or other transfer unit, into a transit stack and eventually to a warehouse. Each movement creates a separate custody point, and a different party may record the quantity at each point.
The wider Owendo port complex includes commercial berths and distinct cargo-handling and storage areas, as shown in the Office des Ports et Rades du Gabon overview of Port d’Owendo. Consequently, a document stating only that the rice was “discharged at Owendo” does not establish where the relevant count was taken or which party had custody when the difference arose.
This distinction directly affects the claim. If the vessel’s tally agrees with the quantity landed but the warehouse later receives fewer bags, the evidence points beyond the immediate ship-to-shore operation. If the ship-side and landing tallies already differ, the discharge stage requires closer examination. If the records were taken at different times or cover different parcels, the figures cannot safely be compared until those differences are corrected.
A reliable Gabon cargo survey must therefore fix both place and time:
- the hold, hatch and parcel from which the bags were discharged;
- the exact point at which the shipboard tally was taken;
- the point at which the shore or terminal accepted custody;
- the route to the stack, warehouse or consignee’s premises;
- any intermediate rehandling, rebagging or temporary storage; and
- the time at which each party’s count closed.
Without those boundaries, two accurate records may still disagree because they measure different stages of the movement. The precise terminal, transfer point and closing time help determine whether the apparent discharge shortage arose aboard the vessel, during discharge, inside the terminal or during onward delivery.
The commercial story behind the dispute
The rice parcel was represented in the transport documents by a stated number of bags and a stated weight. After the relevant ship-to-shore movement, the destination records showed fewer bags, a lower weight or both. A shortage exception was issued.
On opening the file, however, three weaknesses prevented an immediate shortage finding.
First, the draft survey material did not span the complete movement under review. A draft survey estimates the change in vessel displacement, subject to measurement, density, tank, constant and calculation limitations. It can provide valuable mass evidence, but it does not identify each bag and cannot automatically replace a continuous cargo tally. A partial draft survey sequence cannot safely be extended to an unobserved interval as if it were a complete discharge record.
Second, the bill of lading and mate’s receipt chronology had changed. A later amendment may be entirely legitimate—for example, correcting a clerical error after reconciliation at the load port—but it must be auditable. The surveyor needed the original entry, the amended entry, the time and reason for amendment, the identity and authority of the person making it, and evidence showing which version was used in the manifest, commercial invoice, customs record, insurance declaration and receiver’s expected-stock record.
Third, the parties did not yet share one count at one boundary. A vessel tally, terminal tally, truck count and warehouse receipt are not interchangeable. If each starts and ends at a different time, includes a different parcel or treats torn bags differently, the final difference may be a reconciliation problem rather than a physical loss.
These weaknesses did not defeat the claim. They defined the survey task.
The first survey decision: preserve the parcel and the opportunity to prove it
The immediate operational course was completing a joint tally before the next custody handover. That required cooperation from the vessel, terminal or stevedore, receiver and other attending interests, but it did not require them to agree on liability.
The affected rice had to remain identifiable. Sound bags, torn or slack bags, wet or contaminated bags, sweepings, rebagged units and material whose identity had not been verified were to be marked and recorded separately. Mixing them into a common warehouse stack would make later counting easier operationally but weaker evidentially.
The surveyor’s immediate priorities were:
- define the affected bill-of-lading parcel and its marks, bag type, declared unit weight and hold stowage;
- preserve the original and amended transport records without overwriting either version;
- agree the physical reference point at which the joint count would be taken;
- record the opening time, interruptions, shift changes and final closing time;
- separate sound delivery, damaged delivery, rebagged cargo, sweepings and unverified cargo;
- issue written reservations where access, counting continuity or document production was incomplete; and
- prevent the remaining cargo from passing into another custody stage without a closing record.
This response protects every party. The claimant gains a traceable evidential record. The carrier, terminal and stevedore are protected against an unsupported total derived by subtracting unrelated documents. The insurer receives a file capable of adjustment. Recovery counsel can later see what was observed, what was reported by others and what remains unproved.
The quantity ladder: one movement, several different numbers
The investigation organised the evidence as a quantity ladder. Each record was assigned to the stage it actually measured.
This table exposes a frequent claims error: comparing the bill of lading directly with a warehouse receipt, calling the difference a “discharge shortage,” and ignoring every stage between them. That calculation may identify a commercial exception, but it does not locate the loss.
Bag count and cargo weight must not be confused
Bagged rice is capable of being expressed as both units and mass. The two measures are related, but they are not identical.
A nominal “50 kg bag” is a commercial unit description. Multiplying the number of bags by 50 kg produces a nominal net quantity, not necessarily the cargo’s measured net weight at discharge. Bags may vary within permitted filling tolerances. Packaging has tare weight. Torn bags may be reconstituted into a different number of replacement bags. Sweepings may be weighed in bulk. Wetting can increase gross weight even when sound rice has been lost, while drying or moisture variation may reduce weight without any bag disappearing.
Accordingly, the survey kept two reconciliations in parallel:
- unit reconciliation: number of original bags, sound bags landed, torn or slack bags, replacement bags, empty bags, unverified bags and bags received at the next custody point; and
- mass reconciliation: declared net mass, draft-survey estimates for matched intervals, check-weighing results, weighed sweepings, recovered contents, packaging tare and any reliable weighbridge totals.
The two were linked only where the evidence allowed. An average check-weight could be applied only to the sampled population it reasonably represented. A draft-survey figure could be compared only with records covering the same opening and closing interval. Converting every document into tonnes did not cure a mismatch in parcel, time or custody boundary.
How the joint tally should be constructed
A credible joint tally is not merely a final total signed at the end of discharge. It is an auditable sequence that another person can retrace.
Where parallel tallies differed, the purpose of the shift-end reconciliation was not to force a compromise number. Each difference had to be traced to a particular sling, vehicle, interruption or sheet. If the discrepancy could not be resolved, both figures and the reason for disagreement remained on record.
Testing the amended bill of lading and mate’s receipt chronology
The later documentary amendment was a central issue because it could change the expected quantity before any physical discharge figure was considered. The surveyor treated the amendment as evidence to be authenticated, not automatically accepted or rejected.
The review asked:
- What did the original mate’s receipt record?
- Did it contain any remarks about quantity, condition, tally or shipper’s figures?
- What was changed in the bill of lading or related record?
- Was the amendment made before or after sailing, arrival or notification of the alleged shortage?
- Who requested, authorised and issued the amendment?
- What primary record supported it: load-port tally, warehouse release, customs record, statement of facts or corrected calculation?
- Were all originals and copies consistently amended?
- Did the seller, buyer, bank, insurer, carrier, agent and receiver rely on the same version?
- Did the amendment alter bags, gross weight, net weight, marks, parcel allocation or only a clerical field?
Timing matters. An amendment made before the dispute arose and supported by contemporaneous load-port records carries a different evidential character from a retrospective change first appearing after a destination difference was reported. That distinction does not decide fraud or liability; it determines the weight and further verification the record requires.
Testing the draft survey worksheets
Field work used measurement repeatability checks before accepting the reported variance. Draft survey evidence was reviewed at worksheet level, not accepted merely because a final tonnage appeared on a certificate.
The review considered whether the relevant initial and final readings existed; whether drafts were read on both sides; the vessel’s trim and list; water density; ballast, freshwater, fuel and other consumables; tank soundings; hydrostatic data; calculated constant; arithmetic; timestamps; and whether cargo operations took place during an alleged measurement interval.
Repeatability was important. If readings or inputs changed materially when checked again without a corresponding cargo movement, the resulting uncertainty had to be stated. A transcription error—such as a reversed sounding, incorrect density, misplaced decimal, wrong hydrostatic entry or total carried from another worksheet—could create a variance larger than the alleged bag shortage.
Most importantly, the worksheets covered only part of the movement. Their conclusion was therefore confined to that part. The report did not treat a partial measurement as proof of the entire discharge.
Competing explanations tested
The investigation began with the evidence, not with the party first named in the claim. Each explanation was classified according to whether it was positively supported, remained possible but unproved, or was contradicted by the available record.
The report used disciplined language. “Supported by the available evidence” was reserved for explanations with positive proof. “Not excluded” meant only that the evidence was insufficient to eliminate the possibility. It did not mean that the possibility was the most likely cause.
The reconciliation that a settlement file needs
The settlement-ready account addressed applicable trade allowances and deductibles, then separated a documentary variance, a custody-stage variance and the net unexplained variance. This avoided presenting one subtraction as though it answered every issue.
1. Documentary variance
This compared the governing documentary shipment quantity with the destination quantity on the same unit basis. It identified the commercial exception requiring explanation, but not necessarily where it arose.
2. Ship-to-shore variance
This compared cargo counted at the agreed shipboard boundary with cargo accepted at the agreed shore boundary during the same period. It was the relevant measure for an alleged loss in the immediate discharge leg.
3. Shore-to-warehouse variance
This compared shore acceptance with the next verified custody receipt. A difference here belonged to the inland or terminal transfer leg unless evidence moved the boundary elsewhere.
4. Known exceptions and recoveries
Documented torn bags, recovered sweepings, rebagged quantities, rejected units, retained damaged cargo, acknowledged misdeliveries and authorised samples were accounted for separately. A torn bag is not automatically a total loss; nor should recovered contents vanish from the reconciliation merely because the original package no longer exists.
5. Net unexplained variance
Only the balance remaining after like-for-like reconciliation was described as unexplained. The working logic was:
Matched opening quantity − verified sound delivery − verified damaged delivery − verified recoveries or authorised dispositions = net unexplained quantity
Every term had to refer to the same parcel, unit, period and custody boundary. If those conditions were not met, the report presented the limitation rather than manufacturing precision.
Illustrative adjustment schedule
No actual quantities or values are disclosed in this composite case. A settlement-ready schedule would nevertheless show the calculation transparently.
Trade allowances and insurance deductibles are not interchangeable. A trade allowance may affect whether a commercial variance is actionable under the sale or carriage arrangement. A policy deductible affects the amount payable under insurance. Neither should be inserted merely because it is common in another rice trade.
Mitigation without destroying evidence
The duty to reduce avoidable loss must be balanced against the need to preserve proof. Delaying all handling can expose rice to weather, contamination, infestation, theft, congestion or additional expense. Moving everything immediately can erase the very evidence needed to establish the claim.
A practical mitigation plan would normally include:
- rapid joint counting and photography before onward movement;
- segregation of sound, wet, torn, contaminated and unverified bags;
- controlled rebagging with original-bag and replacement-bag records;
- weighing of sweepings and recovered loose rice;
- preservation of representative packaging, seals, labels and samples where relevant;
- agreed disposal, treatment or salvage procedures for unfit cargo;
- written invitations to interested parties and records of attendance or non-attendance; and
- reservation of rights so operational cooperation is not mistaken for admission of liability.
The surveyor should record when a mitigation step was proposed, who was notified, what response was received and what happened next. That chronology may later matter as much as the quantity calculation.
What the evidence could—and could not—support
At the interim stage, the available material supported an apparent variance requiring reconciliation. It did not yet support a final statement that a particular party had physically lost or misappropriated a stated quantity of rice.
The defensible interim finding was narrower:
- the destination records showed a reported difference;
- the draft survey evidence was incomplete for the whole movement;
- a measurement or transcription error in one compared record required testing;
- the bill-of-lading and mate’s-receipt chronology contained a later amendment requiring authentication;
- the affected parcel had to remain identified and segregated; and
- a joint tally was required before the next custody handover closed the evidential opportunity.
Following that work, the final report could state which differences were explained, which remained unsupported and what net balance—if any—remained unexplained. If the evidence could establish only a range rather than a single exact quantity, the range and its assumptions should be disclosed.
Legal orientation: why The Jordan II is relevant, and why it does not decide this case
In Jindal Iron and Steel Co Ltd v Islamic Solidarity Shipping Co Jordan Inc (The Jordan II) [2004] UKHL 49, the House of Lords considered whether contractual terms could allocate loading, stowage and discharge functions to shippers, charterers or receivers despite Article III rule 2 of the Hague/Hague–Visby Rules. The judgment records that long-standing English authority permitted such an allocation and upheld the contractual arrangement before it. The official judgment identifies the governing bills of lading, incorporated charterparty terms and FIOST wording as central to the result.
Its relevance to an Owendo rice shortage is limited but important: the person physically performing discharge, the person contractually responsible for it and the party legally liable for a proven loss may not be the same. A survey should preserve facts capable of supporting that later analysis.
The judgment does not establish that the carrier, charterer, receiver, terminal or stevedore is liable in this composite case. It concerned steel-coil damage, not this rice outturn, and it applied English law to particular contract terms. A real Gabon file would still require examination of:
- the charterparty and whether relevant terms were effectively incorporated into the bill of lading;
- the bill of lading, mate’s receipt, delivery order, terminal terms and stevedoring agreement;
- the identity and legal position of the claimant;
- the governing law and applicable cargo convention or national legislation;
- contractual notice requirements, time bars, reservations and jurisdiction or arbitration provisions; and
- the precise stage at which the supported loss occurred.
Legal responsibility should follow that analysis. It should not be inferred from the first shortage notice or from the name of the party operating the tally point.
Documents that should remain in one claim file
The evidence should be retained as a connected chronology rather than scattered among operational emails.
Keeping the amended and superseded records together is essential. The draft survey worksheets, bagged rice notices, bills of lading and mate’s receipts, tally records and disposition records should remain connected so adjustment and recovery teams can retrace the decision. A later version should never silently replace the source from which an earlier commercial decision was made.
Lessons for cargo owners, receivers and traders
Cargo interests should not wait for the warehouse’s final stock entry before arranging independent evidence. The survey instruction should be issued as soon as a material tally difference appears. It should identify the parcel and request access at the ship-to-shore boundary while cargo is still moving.
Expected quantity should be checked against original source records before discharge closes. Where a transport document has been amended, the amendment trail should be obtained immediately. Claims teams should also avoid combining a quantity shortage with wetting, contamination or torn-bag damage in one undifferentiated figure. Missing cargo and delivered-but-damaged cargo require different calculations.
Lessons for carriers, vessel interests and P&I correspondents
The vessel’s protection lies in a clear, contemporaneous record. Any disagreement with a shore tally should be notified at the shift or hatch where it arises, not first raised after the vessel sails. Remaining cargo, empty holds, sweepings and damaged bags should be jointly examined where practicable.
Contract clauses allocating discharge functions should be preserved and reviewed, but they should not replace factual investigation. Even where another party performs discharge, the file still needs evidence showing what left the vessel, under whose control, and in what condition and quantity.
Lessons for terminals, stevedores and inland custodians
Each custodian should sign only for the quantity accepted at its own defined boundary and time. Truck sheets, gate records, seal controls and warehouse receipts should link back to the discharge parcel. When bags are reworked, the record should connect the original package count, recovered contents, new bags and waste.
An unexplained difference between ship tally and warehouse receipt should not automatically be assigned to the terminal. It should be broken down by each transfer stage. That same discipline also prevents an inland loss from being incorrectly presented as a vessel discharge shortage.
Lessons for insurers, brokers, adjusters and recovery teams
Early reserves should reflect uncertainty. A reported gross difference may reduce after correction of duplicated sheets, authentication of amendments, rebagging credits and reconciliation of custody stages. It may also increase if a partial draft survey had concealed an unrecorded interval. The reserve file should state which components are confirmed, estimated or disputed.
Recovery prospects depend on more than quantum. Notice, contractual allocation, time bars, forum and the location of the loss must be established. A technically strong survey file gives legal advisers the factual platform to assess those issues without asking the evidence to answer a question it was never designed to record.
A practical response checklist for an apparent rice shortage at Owendo
Within the first hours
- Notify the vessel, agent, terminal, stevedore, receiver, insurer and other relevant interests.
- Invite a joint survey without prejudicing rights.
- Identify the bill-of-lading parcel, hold, marks and expected quantity.
- Freeze and copy the current tally totals; preserve later corrections separately.
- Establish the ship-to-shore counting point.
- Segregate affected, damaged, rebagged and unverified rice.
- Prevent the next custody handover from closing without a quantity record.
Before the end of the shift
- Compare parallel tallies by hatch, gang, sling or vehicle.
- Reconcile carried-forward totals and record unresolved differences.
- Record interruptions, weather stoppages, equipment breakdowns and counter changes.
- Count and weigh recoveries, torn bags and sweepings where practicable.
- Obtain signatures or record who declined to sign and why.
Before the vessel sails or the parcel leaves the terminal
- Confirm the final outturn and any cargo remaining on board.
- Obtain original draft survey worksheets and transport-document versions.
- Photograph relevant holds, stacks, damaged bags and closing condition.
- Issue a reasoned reservation or letter of protest for unresolved differences.
- Record onward truck, seal, gate and warehouse controls.
Before claim submission
- Separate documentary, ship-to-shore and inland variances.
- Convert units only on a supported weight and tare basis.
- Credit delivered damaged cargo, rebagged cargo and recoveries correctly.
- State the net unexplained variance and its uncertainty.
- Review contract allocation, notice, time bar, governing law and forum.
- Present quantum separately from liability.
Questions frequently asked after a bagged rice shortage
Does a bill-of-lading quantity prove the amount discharged short?
Not by itself. It is an important contractual and documentary starting point, and its evidential effect depends on the governing law, wording and the claimant’s legal position. A discharge shortage still requires a matched destination outturn and a defensible custody-stage reconciliation.
Can a draft survey replace a bag tally?
No. A draft survey estimates mass from the vessel’s displacement. A tally counts cargo units at a defined point. They can corroborate one another when they cover the same parcel and interval, but they measure different things and have different uncertainty.
Are torn bags counted as shortage?
Only the quantity actually lost should enter the shortage balance. A torn bag delivered with recoverable contents is damaged cargo, not automatically one missing bag. Recovered loose rice, rebagged units and waste should be separately counted or weighed.
What if vessel and shore tally figures disagree?
Compare them during the same shift and trace the difference to the smallest available operational segment. Preserve both records if the disagreement cannot be resolved. A forced compromise total weakens the evidence.
Why examine an amendment to the bill of lading?
Because it may change the quantity against which the destination outturn is compared. The original entry, amendment authority, timing, reason and supporting load-port evidence are needed to determine how much evidential weight the change should carry.
Who is responsible for a shortage during discharge?
That cannot be answered from the location of the shortage alone. The evidence must show whether a real loss occurred and at what stage. The applicable contract, incorporated terms, governing law and cargo regime then determine how responsibility may be allocated.
Closing insight
The strongest result in a bagged rice shortage investigation is not always confirmation of the number first claimed. It is a transparent explanation of the cargo’s movement: the quantity supported at the opening point, the quantity observed at each handover, the known damaged or recovered cargo, the limits of each measurement and the balance that remains unexplained.
In this composite Owendo case, the decisive action was to preserve both versions of the documentary history and complete a joint tally before the rice passed into the next custody stage. That approach kept the evidence neutral while it was still recoverable. It allowed measurement error, transcription error, physical loss and custody-stage variance to be tested separately. It also produced a file from which insurers, cargo interests, carriers and recovery teams could assess mitigation, quantum and contractual responsibility without confusing allegation with proof.

Editorial and legal note
This is a composite research case prepared for professional education. Facts and issues have been combined and anonymised; it must not be represented as the report of a named casualty. The legal section is a general orientation, not legal advice. Every live claim requires review of its own evidence, contracts, governing law, cargo regime, policy wording, limitation provisions and forum.
