15.12.2020

Russian Maritime Register of Shipping (RS) specifies the requirements of the Rules for the Classification and Construction of Sea-Going Ships (the Rules) in terms of ships equipped with hull strength and stability monitoring systems.

The amendments are introduced by Circular letter No. 314-30-1461c accessible at rs-class.org in the Online Information – RS Circulars section. The document enters into force on December 15, 2020.

The Circular provides the order of the assignment of the distinguishing mark HMS in the class notation of ships equipped with hull strength and stability monitoring systems. The relevant requirements will be integrated into the new edition of Section 17 Part XVII Distinguishing Marks and Descriptive Notations in the Class Notation Specifying Structural and Operational Particulars of Ships of the Rules.

The amendments also include the requirements for system’s sensors arrangement depending on the particulars and purpose of ship, sensors’ features and measurement accuracy.

Additionally, the Circular defines the list of documentation submitted to RS, survey procedure during system installation and provides a requirement for annual checks.

Currently, hull strength and stability monitoring systems are not included in the list of ship’s compulsory equipment. The decision on the system installation and arrangement is taken by the shipowner. The systems installed on board a ship enable the crew to receive the information on hull loads and stability changes during the service and loading/unloading operations in a port in real-time mode, thus, enhancing the efficiency and safety of the ship’s operation.
