FSRU to be built to RS class

A Floating Storage Regasification Unit (FSRU) will be built to the class of Russian Maritime Register of Shipping (RS). The agreement on classification of FSRU under construction has been signed between RS and Hyundai Heavy Industries, the Republic of Korea.

According to Mr Georgy Bedrik, Head of the RS Planning and Marketing Division, one of the key features distinguishing the FSRU from other gas carriers built to the RS class involves the LNG regasification system, systems for LNG loading from other LNG carriers as well as export of the regasified product to shore. The substantial advantage of such ships consists in possibility to supply gas to consumers bypassing the phase of cargo handling at onshore regasification terminals. The time frames of construction of a FSRU and its commissioning works are generally much shorter than construction of an onshore LNG terminal.

He also remarked that FSRU classification is a follow-up of the RS classification activities for LNG carriers construction being carried out since 2011. At present, the level of RS competence allows the organization to carry out survey of ships of any complexity, including high-tech vessels to transport hydrocarbons in the Arctic and other freezing seas.

RS will carry out survey during construction of the FSRU in compliance with the RS Rules, as well as other applicable national and international requirements. RS class notation: ✪ Arc4 AUT1-ICS OMBO EPP ANTI-ICE LI CCO ECO-S BWM (E-S) WINTERIZATION (-30) GFS Gas carrier type 2G (methane). The ship will be foreseen with anti-icing protection means to ensure its continuous operation at low temperatures (down to 30 ). The Arc4 ice class will enable the ship navigation in the average one-year ice up to 0.9 m thick in summer and autumn.

Main particulars:

  • length overall 287 m;
  • breadth 46.4 m;
  • draught 26.4 m;
  • deadweight 82,140 t;
  • gross tonnage 119,100;
  • main engine 2 11,700 kW;
  • auxiliary engines 2 5,850 kW;
  • LNG storage capacity 174,100 cu m.

The ship is being built for OOO Gazprom Flot. The delivery of the ship to the customer is scheduled by the end of 2017.


Classification of gas carriers is one of strategic trends of the RS activity. Since 1985, the Rules for the Classification and Construction of Gas Carriers are being published by RS. RS was one of the first in Russia to start active training of specialists in the area of gas carriage and at present possesses all necessary resources for supporting any large project in this field. In addition, RS reviews technical documentation for novel technological solutions under the Approval in Principle (AIP) service.

Vasily Dinkov type 70,000 dwt Arctic shuttle tankers, Sibur Voronezh type LPG carriers of 20,600 cu m cargo capacity, and Veliky Novgorod type large membrane LNG carriers of 170,000 cu m cargo capacity have been built with the RS active participation. Nowadays, 42,000 dwt Arctic shuttle tankers as well as the unique LNG carriers of ice class Arc7 with membrane-type cargo tanks of 172,000 cu m cargo capacity are being built under the RS survey for the Russian project Yamal LNG.

Established in 1913, Russian Maritime Register of Shipping (RS) is one of the leading classification societies. Recognised by the European Union. Member of IACS. The RS activity is aimed at enhancing high standards of maritime safety and minimising the negative impact of human activities on the environment through scientifically based risk assessment and risk management procedures.
