What is a Classification Society?

A Classification Society is an independent organization that provides shipowners, shipbuilders and insurers with technical services to ships in compliance with its own Classification Rules and the International Conventions.
In brief the principle work of the Classification Society is to undertake surveys to ensure vessel’s safety, safety of life at sea and to preserve clean ocean environment.

A Classification Society does not design, build, own, operate, charter, repair, finance or insure ships.

There are about fifty organizations world-wide that provide marine classification services. The most famous and first class Classification Societies are members of IACS.
