The eighth small-draught "double-hulled" tanker barge was launched; the barge is built by the project of Marine Engineering Bureau

On 17th of April 2019 it was launched the eighth ROB20 small-draught "double-hull" non-self-propelled tanker barge "Belmaks 8" of class "O" of the "Novaya Belskaya" type (building number 4108).
 
Characteristics of the barge, namely 6000 t of cargo (at draught 2.75 m) while light weight is 880 t let to announce this project as an unique one.
 
A series of eight ROB20 tanker vessels and two RDB20 dry-cargo vessels is being built by leasing scheme for the Pola Raise shipping company (St. Petersburg); the customer (lessor) is the State Transport Leasing Company.
 
Prj. ROB20 is designed by Marine Engineering Bureau.
 
The contract for the construction of barges with operating draughts from 1.20 to 2.7 5m was signed on 31 of October 2017.
 
While designing the hull of ROB20 prj. with overall dimensions of 118 x 22.6 x 3.0 m, computational methods were widely used, which made it possible to "compensate" additional double bottom and double sides; so the carrying capacity is up to 6000 t with a draught 2.75 m. This is definitely a record for inland navigation vessels.
 
The carrying capacity is 4590 t at draught 2.20 m, and 3560 t at draught 1.80 m.
 
Years ago the world's first oil barges set the same records, they also had a very long and flat hull design with a minimum weight of the hull. In 1885, they were designed and built in Tsaritsyn and Saratov by an outstanding Russian engineer Vladimir Grigorevich Shukhov.
 
New barges are intended for transportation of oil with a flash point of 60 degrees and above; the main cargo is masut through the Belaya River and the Volga River, including reservoirs.
 
Therefore, the class of the Russian River Register is O 2.0.
 
As the tug-pushers are supposed to be the same "Ural" / "Volgar" type ones (at the first stage).
 
For information, old "Belskaya" type barges of the P-27 prj. with river class "P" in the initial single-hull version at draft of 1.80 m took on board 2,960 t of cargo, and at a maximum draft of 2.60 m took onboard 4590 t.
 
So one may observe an increase in the abilities of new ROB20 barges, both in capacity of transported cargo and in the vessel's class, plus the "double-hull" construction as a basic criterion.
