A cargo claim usually arrives long after the ship has sailed. The receiver's surveyor writes to the owner months later alleging wet damage across two thousand tonnes; by then the vessel is on the other side of the world, the crew who worked the hatches have paid off, the hold has carried three cargoes since, and the weather logs for the voyage are whatever someone thought to keep. The claim will be decided almost entirely on documents created — or not created — during a few hours in a port that nobody thought were important at the time. That is the central truth of maritime claims management: the outcome is fixed long before the lawyers arrive. Protection and indemnity cover is the shipowner's shield against third-party liability, provided through mutual clubs that between them cover roughly 90% of the world's ocean-going tonnage, and it is remarkably broad. But the club can only defend what the ship can evidence, and cover itself can be prejudiced by a master's signature on the wrong piece of paper. This guide covers what P&I is and how the club structure works, the main claim categories, the notification duty and the club correspondent, the evidence that decides claims and how to preserve it, the documentary mechanics of clausing and protests that protect cover, time bars, and building a loss-prevention discipline that pays for itself. Because every one of those defences is a record created at the right moment and retrievable years later, book a Marine Inspection demo to see incident and evidence records managed in one place.

What P&I Is, and What It Is Not
The first thing to be clear about is the division of labour between the two policies a ship carries. They are not alternatives, and confusing them is the source of a great deal of misplaced confidence. See compliance and incident records in a demo.
Hull & Machinery
Covers the ship
Physical damage to the vessel herself — her hull, her machinery, her equipment. A commercial, fixed-premium market product. If the ship is damaged, this is the policy that responds.
Protection & Indemnity
Covers everyone else
The owner's third-party liabilities — the injured crew member, the cargo owner whose goods were damaged, the coastline fouled by a spill, the authority that must remove the wreck. Mutual, not-for-profit, and open-ended in a way commercial insurers were never willing to write.
The split exists for a historical reason that still explains the structure. The British Merchant Shipping Act of 1854 imposed third-party liabilities on shipowners that went well beyond what the commercial marine market would underwrite, so owners formed mutual Protection Clubs to fund them collectively. Separate Indemnity Clubs later formed to cover contractual cargo liabilities under bills of lading, and in 1874 the two merged into the P&I club as it exists today. By 1884 five clubs had entered the first pooling agreement, sharing large claims among themselves — the ancestor of the modern International Group.
How the Club Structure Works
Understanding the mutual model matters because it explains both the breadth of cover and the member's obligations. A club is not an insurer selling a product to a customer; it is an association of shipowners funding each other's liabilities.
Mutual, member-owned
Each club is an independent, not-for-profit mutual association owned by its shipowner and charterer members, overseen by a board or committee elected from the membership and run day to day by professional managers.
Calls, not premiums
Members contribute through calls rather than fixed premiums, based on entered tonnage and claims record. If the pool cannot meet current claims, members can be asked for a further call — the mutuality is real, not nominal.
The International Group
Twelve clubs form the International Group, together covering approximately 90% of the world's ocean-going tonnage, with total entered tonnage exceeding 1.1 billion gross tons at recent renewals.
The Pooling Agreement
Claims above an individual club's retention — set at USD 10 million per claim for the 2025/26 policy year — are shared across the Group, distributed pro rata by each club's share of Group tonnage up to USD 100 million, above which the Group's collective reinsurance responds.
Services beyond indemnity
Clubs provide claims handling, legal advice, loss prevention guidance, and a global network of local correspondents. In practice the advisory function is used far more often than the indemnity.
Two consequences follow for an operator. First, the capacity is enormous by design — the pooling structure exists precisely so a single catastrophic casualty does not sink a club, and no International Group club has failed in modern maritime history. Second, because it is mutual, the club's interests and the member's are aligned: the club would rather help you avoid or defeat a claim than pay it, which is why the correspondent network and the loss-prevention advice are free at the point of use and should be used early and often.
The Main Claim Categories
P&I cover is deliberately broad, but claims cluster heavily into a few categories — and cargo dominates by volume. See defect and incident tracking in a demo.
Cargo
Cargo loss and damage
The carrier's liability for goods damaged, lost, or short-delivered during carriage under the bill of lading. Historically the single largest claim category by count — club records have shown cargo claims running at over 40% of all claims reported. Wet damage and physical damage lead the list.
People
Personal injury, illness, and death
Liability for loss of life and personal injury to crew, passengers, and others on board — including medical costs, disability, repatriation, and dependants' claims. Individually the highest-value exposures after pollution.
Pollution
Pollution by oil and other substances
Cleanup costs and third-party pollution claims, including bunker spills from a ruptured tank. The catastrophic category — major spill response can run to the hundreds of millions, which is exactly why the pooling and reinsurance layers exist.
Property
Collision, contact, and wreck removal
Damage to other vessels and to fixed or floating objects such as berths, cranes, and buoys, beyond what the hull policy covers, plus the liability to remove a wreck — an obligation that can vastly exceed the ship's own value.
Other
Stowaways, fines, and legal costs
Stowaway repatriation, certain fines, quarantine and diversion expenses, and the legal costs of defending claims — often the practical bulk of what a club actually spends on a member.
Cover has limits, and they matter. Deliberate acts are not covered — intentional pollution will not be indemnified — and fines for regulatory non-compliance may be excluded. More pointedly for daily operations, non-compliance with flag state safety and environmental requirements can itself affect cover, and certain documentary failures can prejudice it outright. P&I is broad, but it is not a substitute for running the ship properly.
The claim is decided by records made years earlier
Make the Evidence Exist Before You Need It
Hold cleanliness records, maintenance history, defect close-outs, drill logs, and inspection reports are the material that defends a claim raised eighteen months after the voyage. Marine Inspection captures inspections and incidents at the time they happen, tracks defects and corrective actions to verified closure, holds certificates and survey status, and keeps it all timestamped and retrievable — so when a claim lands, the evidence is already assembled. Book a 30-minute demo, or start a free trial today.
Notification and the Club Correspondent
When an incident occurs that may give rise to a claim, the member's first obligation is to tell the club — and the club's first act is to put someone alongside. This is the mechanism that most operators under-use.
1
Notify early, notify wide
Any incident likely to give rise to a claim must be advised to the club or its local correspondent. The threshold is "likely to give rise", not "certain to" — a late notification narrows every option that follows.
2
The correspondent attends
Clubs maintain a global network of local correspondents with local legal knowledge and survey contacts. On notification, the correspondent or an appointed surveyor or lawyer attends the vessel to collect evidence and protect the member's interests.
3
Seek advice before acting
Where the master is uncertain — about a remark on a bill of lading, a demand from a shipper, an allegation from a terminal — the standing advice is to consult the local correspondent first. Duty officers are contactable around the clock.
4
Cooperate and preserve
Ship's staff make appropriate log entries, preserve all evidence, and cooperate with the correspondent and the club's surveyor. What the surveyor collects — log copies, stowage plans, photographs — becomes the defence file.
The reason speed matters is structural, not procedural. Claims are very often raised well after the ship has departed the port, and by then it may be too late to collect the evidence that would deny or minimise exposure. The maritime environment is actively hostile to evidence: weather, tidal action, and the simple operational need to keep working the ship destroy the physical traces quickly. Evidence gathered contemporaneously is also worth far more than an account reconstructed months later — courts and surveyors both know the difference.
The Evidence That Decides Claims
Successful claims handling depends on evidence about the incident, and collecting and preserving it is explicitly the responsibility of the vessel's officers and crew. This is the practical core of the whole subject. See structured evidence capture in a demo.
The logs, contemporaneous
Deck, engine, and bell books, weather records, and the appropriate entries made at the time. A log written up properly during the event is evidence; one tidied afterwards invites the suggestion it was tidied for a reason.
Photographs and video
Of the cargo, the hold, the damage, the stow, the equipment, the scene. Photographs with intact original metadata are powerful precisely because their timing can be verified — take more than seems necessary, immediately.
Cargo documents
Mate's receipts, bills of lading, stowage and lashing plans, tally records, pre-loading survey reports, hold cleanliness records, ventilation logs, and any notes of pre-loading damage.
Technical records
Maintenance history, defect records, equipment testing, alarm and monitoring data, and VDR information where an incident may become serious — preserved deliberately before it is overwritten.
Statements while memory is fresh
Accounts from those involved and any witnesses, taken promptly. Injuries at a berth are frequently unwitnessed, which makes the immediate, contemporaneous account disproportionately important.
Correspondence, in writing
Protests, notices to stevedores and terminals, exchanges with agents and charterers. Any verbal agreement — a joint survey date, an acknowledgement of damage — must be confirmed in writing to exist at all.
The unifying principle is that evidence must be created at the moment, not assembled afterwards. Every category above is trivial to capture on the day and impossible to reconstruct a year later, which is why claims are so often lost not on the merits but on the file. An operator whose vessels systematically record inspections, defects, maintenance, and incidents as a matter of routine is building the defence to claims that have not yet been made.
The Documentary Mechanics That Protect Cover
There is a narrow set of documentary acts, mostly around loading, where a master's decision directly determines whether the owner has a defence — or even whether cover responds at all. These deserve to be understood precisely.
Clausing the bill of lading
Clausing means inserting remarks qualifying the bill's statements as to the quality, quantity, and apparent condition of the goods. A bill without such remarks is a "clean" bill. Where shippers tender damaged or defective cargo, the master's duty is either to reject the goods — with a surveyor's assistance where needed — or to accept them and issue a claused bill stating the deficiency.
Failing to clause can prejudice cover
This is the sharpest point in the whole subject. If bills of lading are not claused when they should have been, P&I cover may be prejudiced — meaning there may be no insurance for the resulting cargo claim at all. The master's signature is, in that moment, an underwriting decision.
The mate's receipt is not enough on its own
Describing the cargo's external condition on the mate's receipt alone is insufficient; the description must carry through to the bills of lading. Where the ship's figures differ on a bulk cargo, the master enters the ship's figure on the mate's receipt before signing and gives the shipper a copy, having them acknowledge the discrepancy in writing.
The letter of protest
Where a shipper refuses to accept the endorsement, the master writes a letter of protest setting out the discrepancy and stating the bill is signed under protest, with a copy stapled to each original in the set. For stevedore damage, the master notes protest against them with full details of the cargo and damage. Independent verification — a draught survey for bulk, ullage readings for tankers — turns an assertion into a figure.
The letter of indemnity is not a solution
Shippers under letter-of-credit pressure will offer a letter of indemnity in exchange for a clean bill on damaged cargo, because a claused bill breaks the credit. Accepting one in exchange for signing a false bill amounts to complicity in fraud — it is unenforceable, it destroys cover, and it exposes the individual personally. There is no version of this that ends well.
The pressure at that moment is real: a claused bill can fail the letter of credit guaranteeing payment for the cargo, so the commercial push to sign clean is intense and comes from people who will not be in the witness box. The correct response is procedural, not heroic — where a remark's effect is uncertain, contact the club correspondent before making it, because some remarks do not protect the carrier and others have consequences for the shipper's bank presentation that can be resolved with the right wording.
Time Bars and the Burden of Proof
Two legal realities shape everything an operator does after an incident, and both cut hard.
The one-year cargo time bar
Cargo claims commonly become time-barred one year from the day the cargo was delivered or should have been delivered, under the Hague-Visby regime. Miss it and the claim is extinguished regardless of merit — though regimes vary internationally, and the Hamburg Rules run to two years.
Different bars for different claims
Personal injury and oil pollution claims run to their own, different limits. Assuming one period applies across the board is a classic and expensive error — the club or its local correspondent can advise the position in any given jurisdiction.
Notice of visible damage
Under Hague-Visby, the carrier must be notified of loss or damage within three days of delivery where the damage is apparent — a short fuse that makes prompt discharge documentation valuable.
The burden and why the bar is short
The short limitation period is the necessary complement to the burden of proof, which rests substantially on the shipowner. The owner must be able to show what happened — which is only possible from records made at the time.
Package limitation
Hague-Visby caps the carrier's liability per package or per kilo in SDR terms unless the shipper declares value on the bill, which is why a claim's headline figure and its recoverable amount can differ dramatically.
The practical instruction from all of this is to calendar the bar the moment an incident occurs, not when the claim arrives. By the time a claimant makes contact, months of the period may already be gone — and the evidence window closed long before that.
Loss Prevention as Claims Management
The cheapest claim is the one never made, and the clubs themselves invest heavily in loss prevention precisely because mutuality means every member pays for every member's carelessness.
Systematic cargo care
Hold and tank preparation, cleanliness records, ventilation logs, lashing and securing checks, and stevedore damage reporting — the routine attention through loading, carriage, and discharge that prevents most cargo claims outright.
Pre-loading surveys
An independent pre-shipment survey gives objective evidence of cargo condition on loading. The survey cost is trivial next to the exposure it defines, and it converts a later argument into a documented fact.
Injury prevention and reporting
Safe systems of work, enclosed-space discipline, and near-miss reporting reduce injury claims at source — and a near-miss recorded is a claim prevented, on the same logic as any safety programme.
Pollution response readiness
Investigate any allegation immediately, stop pumping and secure valves, notify port control and the correspondent, identify other potential sources, take properly sealed and dated samples, and preserve equipment and testing records.
Use the club's advice
Clubs publish loss-prevention guidance, master's handbooks, and practical notes for ships' personnel, and their claims handlers give proactive advice to avoid or minimise losses. It costs nothing and is written from the claims file.
Make records routine, not reactive
The single highest-leverage change: capture inspections, defects, maintenance, and incidents as normal practice, so the evidence exists automatically rather than depending on someone recognising an incident's significance in the moment.
That last point is where claims management stops being a legal function and becomes an operational one. Nobody on a hatch at three in the morning knows which of the day's events will become a claim eighteen months later — which is exactly why the discipline has to be systematic rather than selective. The operator whose fleet records hold cleanliness, ventilation, defect close-outs, maintenance history, drills, and incident reports as a matter of routine is not doing paperwork; they are pre-building the defence to claims not yet made, and shortening the notification-to-correspondent path when one is. Scattered across emails, notebooks, and a dozen spreadsheets, that same material is functionally unavailable when it counts. Book a demo to see inspection, defect, and incident records as one retrievable system.
Frequently Asked Questions
What is the difference between P&I and hull and machinery insurance?
Hull and machinery covers physical damage to the vessel herself and is a commercial, fixed-premium product. P&I covers the owner's third-party liabilities to everyone else — injured crew and passengers, cargo owners, pollution victims, authorities removing a wreck, and damage to other vessels and property — and is provided mutually by not-for-profit clubs.
What does P&I insurance cover?
Loss of life and personal injury to crew, passengers and others on board; cargo loss and damage; pollution by oil and other hazardous substances; wreck removal; collision and damage to property including fixed and floating objects; stowaways; certain fines; and legal costs. Deliberate acts such as intentional pollution are not covered, and fines for regulatory non-compliance may be excluded.
How does the International Group pooling agreement work?
Twelve clubs covering roughly 90% of the world's ocean-going tonnage share claims exceeding an individual club's retention — USD 10 million per claim for the 2025/26 policy year — distributing the excess pro rata by each club's share of Group tonnage up to USD 100 million, above which the Group's collective reinsurance responds. It gives each club capacity for catastrophic losses.
When must a P&I claim be notified?
As soon as an incident occurs that is likely to give rise to a claim, the club or its local correspondent must be advised. The correspondent, or an appointed surveyor or lawyer, then attends the vessel to collect evidence and protect the member's interests. Speed matters because claims are frequently raised long after the ship has left the port, by which time the evidence may be gone.
What evidence should be preserved after an incident?
Contemporaneous log entries and weather records, photographs and video with intact metadata, mate's receipts and bills of lading, stowage and lashing plans, tally and pre-loading survey records, hold cleanliness and ventilation logs, maintenance and defect records, alarm and VDR data where serious, statements from those involved taken while memory is fresh, and all correspondence and protests in writing.
Can failing to clause a bill of lading affect P&I cover?
Yes. If bills of lading are not claused when they should have been, P&I cover may be prejudiced — meaning there may be no insurance for the resulting cargo claim. Where damaged cargo is tendered, the master must either reject it or issue a claused bill stating the deficiency, and should contact the club correspondent before making any remark whose effect is uncertain.
Should a master accept a letter of indemnity for a clean bill?
No. Shippers offer letters of indemnity because a claused bill breaks the letter of credit, but accepting one in exchange for signing a false bill amounts to complicity in fraud. It is unenforceable, it destroys insurance cover, and it exposes the individual personally. The correct route is to clause accurately, protest in writing, and involve the club correspondent.
What is the time bar for cargo claims?
Cargo claims commonly become time-barred one year from the day the cargo was delivered or should have been delivered under Hague-Visby, and the bar is absolute — a missed deadline extinguishes the claim regardless of merit. The Hamburg Rules run to two years, and personal injury and pollution claims have their own separate limits. Notice of apparent damage must be given within three days of delivery.
