Various classification societies draw up design and construction regulations as well as guidelines for the maintenance of ships and monitor compliance with them.  RINA (Registro Italiano Navale) is a relevant classification society within IACS (International Association of Classification Societies), under which shipping companies can register their ships. With the RINA certification, a company testifies that it meets the requirements of the class and is able to perform services according to the specifications of RINA on the respective registered ships.
