The Oka Shipyard put into operation the lead small-draught ROB20 "double hulled" oil barge "Belmaks 1" with deadweight 6000 t
On 17th of May 2018 Oka Shipyard (general director Vladimir Kulikov, shipyard is a part of UCL holding) put into operation the lead small-draught ROB20 "double-hull" non-self-propelled oil barge "Belmaks 1" with deadweight of 6000 t of class "O" of the "Novaya Belskaya" type (building number 4101).
Barge characteristics - 6000 tons of cargo (2.75 m draught) at an empty weight of 880 tons, it is possible to classify the project as a unique.
A series of ten vessels is being built by leasing scheme for the Belmax 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 was signed on October 31, 2017. The vessels are planned to be built and handed over to the customer in the first half of 2018.
While designing the hull prj. ROB20 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 tons at draught 2.75 m. This is definitely a record for inland navigation vessels.
The carrying capacity is 4590 tons at draught 2.20 m, and 3560 tons at draught 1.80 m.
Some time ago the world's first oil-loading barges were set the same records, which also had a very long and flat hull design with a minimum mass of the hull. In 1885 they were designed and built in Tsaritsyn and Saratov by an outstanding Russian engineer Vladimir Grigorievich 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 take on board 2,960 tons of cargo, and at a maximum draft of 2.60 m - 4590 tons.
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.
