The Oka Shipyard has launched the fourth small-draught "double-hulled" oil barge "Belmaks 4" of ROB20 prj. with deadweight of 6.000 tons

On 5th of July 2018 Oka Shipyard (general director Vladimir Kulikov, shipyard is a part of UCL holding) has launched the fourth small-draught "double-hull" non-self-propelled oil barge "Belmaks 4" of the ROB20 prj. with deadweight of 6000 t of class "O" of the type "Novaya Belskaya" (building number 4104).
Characteristics of the barge, namely 6000 t of cargo (at draft 2.75 m) with light weight of 880 tons provide to announce this project as an unique one.
A series of ten 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 the 31st 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 take on board 2,960 t of cargo, and at a maximum draft of 2.60 m take 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.
The keel of the lead ROB20 vessel (building No. 4101) "Belmaks 1" was laid down on 22.11.2017. She was launched 19.04.2018. Vessel was accepted for operation on 17.05.2018.
The keel of the second vessel (building No. 4102) "Belmaks 2" was laid down on 30.11.2017. She was launched 22.05.2018. Vessel was accepted for operation on 31.05.2018.
The keel of the third vessel (building No. 4103) was laid down on 20.12.2017. She was launched 07.06.2018. Vessel was accepted for operation on 29.06.2018.
The keel of the fourth vessel (building No. 4104) "Belmaks 4"was laid down on 19.01.2018. She was launched 05.07.2018.
The keel of the fourth vessel (building No. 4104) "Belmaks 4"was laid down on 19.01.2018.
The keel of the sixth vessel (building No. 4106) "Belmaks 6"was laid down on 29.03.2018.
The keel of the seventh vessel (building No. 4107) "Belmaks 7" was laid down on 26.04.2018.
