What is Classification Society?

A classification society is an organisation that helps maintains technical standards for the construction of vessel and its operation. Classification society also certify that the construction of a vessel is in accordance with relevant standards, regulations and also carry out surveys to ensure that vessel is in always compliance with the required minimum standards.

Why Classification Society is necessary?

As per SOLAS Chapter II, Regulation 3-1, a vessel need to be classed.

“Ships shall be designed, constructed and maintained in compliance with the Structural, Mechanical and Electrical requirements of a classification society which is recognised by the Administration”


It was for the underwriters that the classification society was 1st created because the underwriters required guidance on assessment of maritime risks. So insurer would only cover a ship provided it is built and maintained to class requirements and standards.

To demonstrate that a ship was classed with a society, their mark was put on the ship side which eventually combined with the load line requirement for freeboard.

The Insurance policy in most cases will stand void if the vessel goes out of Class.


Classification society is a big helping hand for the Administration, because of its impartial role and total dedication to standardisation. The administration finds it convenient to entrust the classification society.

The biggest advantage to administration is that vessel can be inspected and surveyed almost anywhere through the global network of the society. By saying that the administration is always legally and morally responsible for its obligation in respect to survey and certification under various convention.
