1.6 Additional Requirements

In addition to the aforementioned requirements, SOLAS also requires the following:

  • Ship Identification Numbers.
  • Regulation XI-1/3 is modified to require ships’ identification numbers to be permanently marked in a visible place either on the ship’s hull or superstructure. Passenger ships should carry the marking on a horizontal surface visible from the air. Ships should also be marked with their identification numbers internally.
  • Continuous Synopsis Record (CSR).
  • Regulation XI-1/5 requires ships to be issued with a Continuous Synopsis Record (CSR), which is intended to provide an on-board record of the history of the ship. This record is commonly known as CSR.

The CSR shall be issued by the administration and shall contain information such as:

  • The name of the ship.
  • The state whose flag the ship is entitled to fly.
  • The date on which the ship was registered with that state.
  • The ship’s identification number.
  • The port at which the ship is registered.
  • The name of the registered owner(s).
  • The registered address of the owner(s). 

Any changes should be recorded in the CSR in order to provide updated and current information together with the history of the changes.
