Oka Shipyard is constructing 5 unique combined platform tankers

Oka Shipyard at Navashino (Vladimir Kulikov is a director) is constructing 5 combined RST54 mixed river-sea going vessels of "Volgo-Don Max" class with deadweight of 5589 t.
RST54 prj. was designed by Marine Engineering Bureau.
On 31.03.2014 readiness is, as follows: about 38% for the head vessel (building No. 5401), about 29% for the secon vessel (building No. 5402), about 24% for the third vessel (building No. 5403), about 10% for the fourth vessel (building No. 5404), about 2% for the fifth vessel (building No. 5405).
The character feature of new concepts are "expanding" narrow places of inland water transport by using new technical decisions. Saying other words, transportation ability is increased by maximal usage of actual way characteristics (maximal available vessel's length and breadth), and mainly by usage extremely fat hull contours, that have never used before in world's practice. And at least, decreasing of air draught allows to avoid running time loss for waiting of bridges drawing in St.-Petersburg and Rostov-on-Don and allows to work through Moscow River till the Yuzhniy port. Usage of RST54 combined vessels provides both directions cargo transportation (oil cargoes towards one direction and dry cargoes towards back direction); that should allow to decrease highways rate due to re-forwarding some cargoes from road to water transportation. Such re-forwarded cargoes include passenger cars, that usually bring from St.-Petersburg to central Russia by car transportation trucks and heavy containers that are prohibited for car trains transportation due to unallowable road loads.
As other mixed river-sea going tankers designed by marine Engineering Bureau, RST54 prj. vessels use full-circle rudder propellers as single movement and manoeuvre facilities.
RRR class notation is of M-PR2.5 (ice30) A.
RST54 vessels satisfy Volga-Don Canal dimensions such as Volgo-Balt Way ones. Vessel's overall length is of 140.85 m, breadth is of 16.60 m, depth is of 5.00 m. She belong to the "Volgo-Don Max" class.
Tanker cargoes with flashpoint restriction more than 60°C is provided in 10 cargo tanks (total capacity of 5446 cub.m.) and 2 slop tanks (total capacity of 207 cub.m.). All cargo tanks are separated from outer shell by double sides and double bottom. Dimensions of double constructions meet requirements of International MARPOL 73|78 Convention.
Cargo system provides closed cargo receiving by shore equipment and cargo discharge by vessel's submersible pumps. Manifolds provide cargo intake and discharge by both sides; they are arranged in the middle and aft parts of the cargo area. Transitional connectors are foreseen in the vessel's supply in order to provide manifolds' coupling with different diameters hoses. Maximal loading capacity for each cargo or slop tank is of 600 cub.m./hour. Summarizes loading capacity for the whole vessel is of 1200 cub.m./hour.
Heating system is served by two steam boilers (capacity of 2.5 t/hour); it provides cargo temperature keeping at level +60°C (when temperature of outboard air is not less than -10°C) and cargo heating from 50°C till 60°C during 36 hours.
Cargo area on the upper deck with 2 m barrier is intended for transportation of cargo that doesn't suffer from wetting (e.g. gravel, rolled metal, heavy containers, cars, etc.). Main deck shell within cargo area is designed for loading 5.5 t/sq.m and for grabs working. Main loading condition is 4500 t of gravel transportation on the open deck.
2-tier containers transportation is foreseen on the main deck; containers are installed on dunnage. Heavy 36 t TEU (120 pcs.) may be transported; these containers cannot be handled by car trains. Vessel's electric station provides ability to transport 45 refrigerator containers.
There is possibility to arrange special removing constructions that can be transformed into 2 additional car decks. Cars loading/unloading are carried out by their own through coastal ramps. Number of transported cars depends on their maximal dimensions. For example, transportation capacity if of 276 when transporting BMW X6; 305 for Ford Mondeo and 322 for Ford Focus.
Two medium-speed diesels of 1200 kW each are used as main engines; they use heavy fuel oil with viscosity of IFO380. There is 230 kWt bow thruster. Ship's electric power plant consists of 3 diesel-generators with capacity of 296 kWt each, and emergency diesel-generator with capacity of 62 kWt.
Crew consists of 12 persons (14 + 1 places).
Vessel's autonomy is of 20 days (due to fuel, water and provision reserves).
Keel of the lead vessel (building No. 5401) was laid down on 16.12.2013.
Keel of the second vessel (building No. 5402) was laid down on 24.01.2014.
Keel of the third vessel (building No. 5403) was laid down on 05.03.2014.
