Part I CLASSIFICATION

Saint-Petersburg Edition 2017 Rules for the Classification and Construction of Sea-Going Ships of Russian Maritime Register of Shipping have been approved in accordance with the established approval procedure and come into force on 1 January 2017. The present twentieth edition of the Rules is based on the nineteenth edition (2016) taking into account the additions and amendments developed immediately before publication. The unified requirements, interpretations and recommendations of the International Association of Classification Societies (IACS) and the relevant resolutions of the International Maritime Organization (IMO) have been taken into consideration. The Rules are published in the following parts: Part I "Classification"; Part II ""; Part III "Equipment, Arrangements and Outfit"; Part IV "Stability"; Part V "Subdivision"; Part VI "Fire Protection"; Part VII "Machinery Installations"; Part VIII "Systems and Piping"; Part IX "Machinery"; Part X "Boilers, Heat Exchangers and Pressure Vessels"; Part XI "Electrical Equipment"; Part XII "Refrigerating Plants"; Part XIII "Materials"; Part XIV "Welding"; Part XV "Automation"; Part XVI "Hull Structure and Strength of Glass-Reinforced Plastic Ships and Boats"; Part XVII "Distinguishing Marks and Descriptive Notations in the Class Notation Specifying Structural and Operational Particulars of Ships"; Part XVIII "Common Structural Rules for Bulk Carriers and Oil Tankers". The text of the Part is identical to that of the IACS Common Structural Rules; Part XIX "Additional Requirements for Structures of Container Ships and Ships, Dedicated Primarily to Carry their Load in Containers". The text of the Part is identical to IACS UR SUA "Longitudinal Strength Standard for Container Ships" (June 2015) and S34 "Functional Requirements on Load Cases for Strength Assessment of Container Ships by Finite Element Analysis" (May 2015). Parts I to XVII are published in electronic format and hard copy in Russian and English. In case of discrepancies between the Russian and English versions, the Russian version shall prevail. Parts XVIII to XIX are published in English and in electronic format only.
