As per SOLAS Chapter XI-1, regulation 5, requires all passenger ships and cargo ships of 500 gross tonnage and above, engaged on international voyages, to have on board a Continuous Synopsis Record (CSR). The primary purpose of the CSR is to provide a history of the ship which can be inspected by appropriate officials.

Whenever any change relating to the entries listed in the current CSR document of the ship has taken place, this change needs to be included without delay in the ship’s CSR file. Following the receipt of copies of one or more amendment forms, PISR is required to issue a revised and updated CSR document as soon as practically possible, but not later than three months from the date of the change.
