The thirteen P&I Clubs which comprise the International Group (the "Group") between them provide marine liability cover (protection and indemnity) for approximately 90% of the world's ocean-going tonnage.

Through the unique Group structure, the member Clubs, whilst individually competitive, share between them their large loss exposures, and also share their respective knowledge and expertise on matters relating to shipowners liabilities and the insurance and reinsurance of such liabilities.

Each Group Club is an independent, not-for-profit mutual insurance association, providing cover for its shipowner and charterer members against third party liabilities arising out of the use and operation of ships. Each Club is owned by its shipowner and charterer members, and its operations and activities are overseen by a board of directors, or committee, elected from the membership. The day-to-day operations of the Clubs are handled by professional managers, either "in-house" or external, who are appointed by and report to their Club board/committee.

The Clubs cover a wide range of liabilities, including 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. The Clubs also provide a wide range of services to their members including claims handling, advice on legal issues and loss prevention, and they regularly play a leading role in coordinating the response to, and management of, maritime casualties.
