How the money works
A protection and indemnity club is not an insurance company. It is a mutual association of shipowners who collectively cover each other's third-party liabilities. That structural difference explains almost everything about how P&I behaves — why calls can be adjusted after the fact, why the clubs share very large claims, and why your relationship with the club matters in a way a commercial policy relationship does not.
| Element | Meaning |
|---|---|
| Advance call | The estimated contribution paid at the start of the policy year |
| Supplementary call | An additional contribution if the year develops worse than expected |
| Release call | The amount payable to leave a club and close out exposure to future supplementaries |
| Deferred call | A budgeted second instalment, announced in advance |
| General increase | A percentage applied across the membership at renewal |
| Owner's deductible | Retained by the member on each claim |
Because the club is a mutual, the members bear the cost of the members' claims. A year with heavy pool claims across the industry affects everyone's renewal, regardless of individual record.
The International Group structure
The major clubs participate in a group arrangement with three layers:
- Club retention — each club pays claims up to a retained amount itself
- The pool — claims above that are shared among participating clubs
- Group reinsurance — a very large market reinsurance programme above the pool, providing the high limits that pollution and wreck removal exposure require
The chart is conceptual, not to scale in currency terms. The point is that the great majority of the limit sits in layers the individual member never touches — but the great majority of claims by number sit in the first two.
What drives your renewal
| Factor | Weight in practice |
|---|---|
| Your own claims record, several years | High |
| The club's overall result and pool experience | High |
| Fleet composition — type, age, trade | High |
| Crew nationality and claims profile | Medium |
| Management quality and loss prevention engagement | Medium |
| Tonnage growth or reduction | Medium |
| Investment returns on club free reserves | Medium |
| Wider market conditions | Medium |
Two of those are within your control: your claims record and the club's perception of your management. The second is not soft — clubs price uncertainty, and a member whose loss prevention is visible and whose claims are notified promptly and handled cleanly is a lower-uncertainty member.
Where P&I claims actually come from
Across the industry, claims cluster in a familiar pattern:
| Category | Notes |
|---|---|
| Crew injury and illness | Frequency leader; strongly influenced by safety culture |
| Cargo | Damage, shortage, contamination — the classic dry bulk and parcel exposure |
| Collision and FFO | Damage to berths, buoys, cables and other vessels |
| Pollution | Low frequency, very high severity |
| Wreck removal | Very low frequency, extreme severity |
| Stowaways and diversion | Route-specific |
| Fines | Customs, immigration, pollution-related |
Crew claims are the frequency leader and the one most responsive to management. Seafarer welfare deficiencies were 10.1% of all Paris MoU findings in 2025, and the same underlying conditions — fatigue, poor familiarisation, weak procedures — produce both the deficiency and the injury.
Being a member clubs want
- Notify early. Late notification prejudices defence and irritates claims handlers.
- Preserve evidence. Logs, photographs, statements taken while memories are fresh.
- Engage with loss prevention. Clubs publish extensive guidance; use it and be seen to use it.
- Fix recurrence. A repeated claim type is a management signal, and the club reads it that way.
- Be transparent at renewal. Undisclosed information discovered later is worse than a bad record disclosed.
- Use FD&D properly. Freight, demurrage and defence cover exists to protect commercial claims — including the demurrage claims that would otherwise be abandoned.
Correspondents and the practical value
The club network of correspondents in ports worldwide is one of the most underused member benefits. When something goes wrong in a port — a crew injury, a cargo dispute, an arrest threat — the correspondent is local, immediate and acting for the member. Masters should know how to reach them, and the contact route should be in the SMS rather than in someone's email.

Frequently asked questions
What does P&I cover?
Third-party liabilities arising from operating a ship: crew, passengers, cargo, pollution, collision liability not covered by H&M, damage to fixed and floating objects, wreck removal, stowaways and certain fines.
What is a general increase?
A percentage adjustment applied across a club's membership at renewal, reflecting the club's overall claims and financial position rather than any individual member's record.
What is the International Group?
An arrangement among the major P&I clubs to pool large claims and purchase collective market reinsurance, enabling the very high limits the industry requires.
Can a shipowner choose any club?
Subject to acceptance. Clubs assess fleet composition, trade, management quality and claims history before offering terms.
