RUSSIAN MARITIME REGISTER OF SHIPPING Corr. RULES FOR THE CLASSIFICATION AND CONSTRUCTION OF MANNED SUBMERSIBLES AND SHIP'S DIVING SYSTEMS 2018 Rules for the Classification and Construction of Manned Submersibles and Ship's Diving Systems have been approved in accordance with the established approval procedure and come into force on 1 January 2018. The Rules establish specific requirements for the manned submersibles, including the passenger submersibles and ship's diving systems, and supplement the Rules for the Classification and Construction of Sea-Going Ships, Rules for the Equipment of Sea-Going Ships and Rules for the Cargo Handling Gear of Sea-Going Ships, as well as the Rules for Technical Supervision During Construction of Ships and Manufacture of Materials and Products for Ships. With this in view, all the applicable requirements of the above Rules cover the manned submersibles and ship's diving systems, unless other requirements are contained in these Rules. Where the above Rules are applied to the manned submersibles and ship's diving systems, the term "ship" shall also mean the manned submersible and ship's diving system.
