Continuous Synopsis Record
Abbreviation: CSR
Statutory document recording the history of a ship's flag, name, owner, ISM company and class society.
In practice
Updated each time flag, name, owner, ISM company, or class changes. Available for PSC inspection at every port; gaps in the CSR raise inspector questions.
Regulatory detail & full definition
Statutory document recording the history of a ship's flag, name, owner, ISM company and class society, required under SOLAS XI-1 Reg. 5 since 2004. The CSR is updated each time any of these particulars change, with the new entry showing the date of change and the previous record retained on board. The document allows port states and inspectors to verify that ownership and operating responsibility are clear, and reduces opportunities to obscure responsibility through opaque ownership chains. The CSR must be available for PSC inspection at every port call.
