Cargo Operations & Claims

A bill of lading is doing three separate jobs at once, and mixing them up is how masters get into trouble. It is a receipt for what was actually loaded — quantity and apparent condition, nothing more. It is evidence of the contract of carriage, recording the terms on which the goods travel, even though the real contract is usually the charterparty or booking note that sits behind it. And once it is issued to order or to bearer, it becomes a document of title — whoever holds it, properly endorsed, is treated in law as the party entitled to the goods at the discharge port.

That third function is what makes the master's signature so consequential. A clean bill certifies that the cargo was received in apparent good order and condition. Banks finance cargo purchases against that certification without ever seeing the goods themselves; buyers pay against it; underwriters price cover against it. If the cargo was visibly rust-stained, wet, or short at the rail and the bill says nothing, the document of title now carries a statement of fact the ship knows to be false — and the carrier has, in effect, agreed with any later holder of that bill that the damage did not happen on its watch.

The mate's receipt is where the true condition of the cargo actually gets recorded — usually by the chief officer, at the rail, hold by hold, before anyone drafts a bill of lading for signature. The bill is meant to be issued consistent with that receipt: if it notes torn bags with contents exposed, or cargo wet before loading, the bill has to carry the same qualification. A clean bill issued over a claused mate's receipt is not a paperwork shortcut — it is exactly the gap a cargo underwriter's lawyer will go looking for first.

The pressure to sign clean anyway usually arrives dressed as a letter of indemnity: the shipper or charterer offers to compensate the carrier for any loss that follows from issuing a clean bill despite known damage. It should be refused every time. An LOI of this kind indemnifies against a statement both parties know to be false — in most jurisdictions that makes it an indemnity against a fraud, which courts will not enforce even though both sides signed willingly. Worse, a P&I club that discovers its member accepted such a letter will typically decline cover for the resulting claim, on the basis that the master knowingly created the loss rather than merely failed to prevent it. The master is left holding the claim with no indemnity left to fall back on.

The correct response costs nothing but a moment's friction on the berth: clause the bill to state the apparent order and condition as observed, in language specific enough that a surveyor could stand behind it years later — not a vague disclaimer a court will simply read as meaningless.

A cargo claim is rarely fought at the discharge port — by the time the receivers' surveyor is on the quay pointing at wet cartons, the case has already been decided by whatever was written down two or three weeks earlier, at the load port. Correspondents and courts weigh contemporaneous evidence far more heavily than anyone's recollection, so the goal at loading isn't to prevent every possible defect — some cargo arrives already damaged — it's to prove, in writing and in photographs, exactly what condition the cargo was in when it crossed the rail.

• Photographs — dated, with something in shot to show scale and location such as a hold number or hatch marking; the cheapest insurance a chief officer can buy.
• Tally and ullage records — independent counts or soundings taken by the ship's own tally staff or duty officers, not simply accepted from the shore tally.
• Hatch cover test certificates — hose, ultrasonic or chalk test results recorded before loading, so a later wetting claim can't be pinned on a leaking coaming the ship never checked.
• Mate's receipts, properly claused — the running record the bill of lading must match.
• Note of protest — a formal statement, typically lodged with a notary or consul, recording that damage, delay or an unsafe condition arose from circumstances beyond the master's control, such as heavy weather met on passage.

None of this is about assigning blame in the moment. It's about making sure that when a claim lands on the company's desk eighteen months later, the file already contains the answer.

A draught survey is how the ship independently checks a bulk or break-bulk cargo quantity without weighing a single tonne of it — by weighing the ship instead, twice, and taking the difference. Drafts are read forward, aft and, ideally, amidships, corrected to the perpendiculars, and converted to a displacement using the ship's hydrostatic particulars. Because the waterplane pivots about the centre of flotation rather than amidships, a trimmed vessel needs a trim correction before that tabulated displacement means anything; because the hydrostatic tables assume standard seawater at 1.025 t/m³, a berth in brackish or river water needs a density correction on top. Strip out everything that isn't cargo — light ship weight, the constant, bunkers, fresh water and stores remaining on board — and what's left is the cargo figure, worked entirely from the ship's own numbers rather than a shore weighbridge.

That independence is the whole point: it gives the master a figure to check the shore or shipper's declared quantity against before signing anything. A small gap is normal — draught surveys carry an inherent error, commonly quoted at around half a percent, from reading accuracy and interpolation alone — but a gap noticeably beyond that is a signal to query the shore figure, request a re-check, or clause the bill of lading quantity rather than simply accepting what the terminal hands over.

Tankers and bulk liquid cargoes work on the same principle with different instruments: ullage and temperature readings, converted through calibration and volume-correction tables, give loaded and discharged volumes, cross-checked against shore meter figures and an independent surveyor's readings for remaining-on-board and outturn. The documentation set is heavier — ullage reports, ship/shore comparison sheets, certificates of quantity and quality — but the underlying discipline is identical: never rely solely on the other side's number when the ship's own instruments can generate one.

Protection and Indemnity cover is mutual insurance — the club is owned by its shipowner members, who pool the risk of liabilities that hull and cargo insurance don't reach, cargo claims chief among them. That mutual structure is also why the club's rules matter so much in practice: cover can be reduced or refused where a member's own conduct created or worsened the loss, which is exactly the position a master creates by signing a clean bill against an LOI, or by admitting liability on a claim without the club's knowledge.

The value the club adds is speed and expertise the ship doesn't have on board. A correspondent or surveyor appointed early can attend the joint survey and record the damage while it's still fresh, building the club's own evidence in parallel with the receivers' — instead of the ship's only record being whatever the receivers' surveyor chose to note. Early notice also lets the club decide, case by case, whether to offer security such as a letter of undertaking to head off a cargo arrest, rather than the master negotiating directly with an unfamiliar claimant under time pressure.

Most P&I entries also carry a deductible, or franchise, below which the club simply doesn't get involved — small claims are for the owner to absorb directly. That's worth remembering before deciding a discrepancy is too minor to report: a shortage that looks trivial in tonnage terms can easily clear the deductible once it's priced at the cargo's actual value, at which point it is very much the club's business — and very much worth having reported early, rather than after a settlement has already been discussed.

Three numerical problems that come up in oral and written papers on this topic — a draught survey worked from first principles, a ship/shore discrepancy sized in real money against a club deductible, and a cargo claim quantified under the package/weight limitation.
