Russian class society updates equipment requirements

RS requirements for the prevention of pollution from ships’ equipment entered into force from 24 July 2020 on circulation of Circular Letter No. 313-04-1421c.

In the letter, RS supplemented testing requirements for shipboard oil pollution prevention equipment and internal combustion engines fitted with emissions reducing devices. Changes also affect ballast water treatment systems, as RS specified technical requirements for tests to comply with IMO ballast water management resolution MEPC.300(72).

RS head of machinery, Mikhail Ivanov said the society reviewed and considered the most frequently asked questions from owners, shipbuilders and their suppliers in clarifying requirements for environmental safety on board vessels.

Other amendments to the rules regarding machinery (Circular Letter No. 313-69-1412c), and piping and boilers (Circular Letter No. 313-68-1416c) will enter into force on 1 September 2020. RS said the amendments supplement the requirements for materials surveys and blanks for manufacturing components and parts.

The society also specifies requirements for seawater cooling and lubricating systems for stern bearings, for hydraulic tests of the pipes, for the choice of materials of fittings for boilers, heat exchangers and pressure vessels of all classes. The list of equipment subject to RS approval and forms issued by RS for this equipment has been harmonised with the new marine equipment approval and certification scheme provided in Appendix 1 to Part I of the Rules for Technical Supervision.

The circulars are available at rs-class.org in the online information – RS Circulars section. The Rules for Technical Supervision can be accessed here.
