The Oka Shipyard laid the seventh small-draught ROB20 "double-hull" oil barge with deadweight of 6000 t of the "New Belskaya" type

On 26th of April 2018 Oka Shipyard (general director Vladimir Kulikov, shipyard is a part of UCL holding) laid keel of the seventh small-draught ROB20 "double-hull" non-self-propelled oil barge "Belmaks 7" with deadweight of 6000 t of class "O" of the "Novaya Belskaya" type (building number 4107).
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 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.
For a significant part of country's shipowners of oil tankers of inland navigation, the date of January 1, 2018 means the termination of operation of their existing tankers built during the Soviet era.
National Russian requirements in the form of Technical Regulations prohibit transportations by "single-hull" tanker the dangerous goods in river (any ones, including light grades of oil and oil products).
The Technical Regulations for Safety of Inland Water transport Objects were approved by the Government of the Russian Federation by the Decree dated August 12, 2010 No. 623 and entered into force on February 23, 2012. According to the provision 108b of Technical Regulations, oil tankers (except the berth-connected ones) with carrying capacity of more than 600 tons, must be provided by double bottom and double sides extending along the entire length and height of the cargo tanks, or cargo tanks must be of independent type. All oil tankers that do not meet the requirements of subparagraph "B" of pointed provision, cannot be operated after December 31, 2017.
It should be specially noted the segment of oil small-draught barges intended to work through the Belaya River (transportation of export oil products). These are completely "fresh" barges with double sides and a single thickened bottom of the project 82380, built in 2002-2003 (!!!), that not meet the requirements of the Technical Regulations, and classic single-hull barges of the project P-27 "Belskaya".
For example, in 2011 small-draught single-hull barges of the "Belskaya" type in conjunction with epy "Ural" pusher tugs exported 880 thousand tons of oil products through the Belaya River from the Ufa refineries, 550 thousand tons in 2010 navigation, up to 1 million tons in 2012 navigation.
In fact, this means that beginning from the 2018 navigation, only 4 barges of 82230 prj. will be operated through the Belaya River, as well as those of the P-27 prj. barges that were significantly modernized by installing the double bottom and sides and increasing the depth (there are two such modernized barges, and four else are going to be modernized during winter repair of 2017-2018). How effective such significant investment is, if the youngest of the barges were built in 1975?
In order to handle this cargo traffic, new "double-hull" oil barges are needed; Oka Shipyard started to build them.
The barges of the ROB20 project are non-self-propelled vessels with overall dimensions of 118 x 22.6 x 3.0 m with a trunk of 1000 mm height, with a double bottom of 800 mm height and double sides of 1400 mm width, with 12 cargo and 2 slop tanks, with transom fore and aft ends. The range of operational sediments is from 1.20 m to 2.75 m. The capacity of the cargo tanks (including the settling tank and the unloading shaft) is 6860 cubic meters.
These 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).
While designing the hull, 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 (when depths allow). The carrying capacity is 4590 tons at draught 2.20 m, and 3560 tons at draught 1.80 m.
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.
The keel of the lead ROB20 vessel (building No. 4101) was laid down on 22.11.2017.
The keel of the second vessel (building No. 4102) was laid down on 30.11.2017.
The keel of the third vessel (building No. 4103) was laid down on 20.12.2017.
The keel of the fourth vessel (building No. 4104) was laid down on 19.01.2018.
