The classification activity of the Register is carried out in accordance with the General Provisions on classification and other activities. Classification surveys of ships and offshore installations in service are regulated by the Rules for the Classification Surveys of Ships in Service, the Guidelines for the Technical Supervision of Ships in Service, the Rules for the Surveys of Inland Navigation Ships in Service (for European Inland Waterways) and other RS Rules depending on the type of ship and the offshore installation. Classification surveys of ships and offshore installations of various purposes are carried out to verify their compliance and the compliance of ship refrigeration units with the rules of the Russian Maritime Register of Shipping and with the normative and technical documents to determine the possibility of assignment, renewal, reassignment, retainment and confirmation of the Register class according to their purpose and to ensure the protection of human life at sea, the safe and reliable transport of passengers and cargo, and the prevention of pollution environment.
The initial survey of ships in service is carried out on ships that are submitted to the Register for classification for the first time when changing class, when determining the possibility of assigning a class to a ship built without technical supervision by the Register, when reassigning the class to a ship, whose Register class was withdrawn.
The initial written request in any form for acceptance of the ship to the RS class is sent by the shipowner to RHO.
