RST54 combined platform tanker "Balt Flot 3" for the first time brought dry cargo (4462 t of crushed stone) as a back voyage transportation
On 22.10.2015 RST54 river-sea combined platform tanker "Balt Flot 3" for the first time brought dry cargo (4462 t of crushed stone) as a back voyage transportation from Karelian port of Ropruchey to Severniy River port of Moscow (limited draught is 3.50 m). Other BF Tanker Company's vessel, namely "Balt Flot 1" and "Balt Flot 2" also loaded cargo of crushed stone for the back voyage after masut unloading at the port of Vysotsk. Thus there are the first RST54 vessels round voyages with loading for both directions.
Oka Shipyard at Navashino (Vladimir Kulikov is a director) is a Builder. Keel of the m/v "Balt Flot 3" (building No. 5403) was laid down on 05.03.2014. She was launched on 24.10.2014. Vessel was accepted for operation on 22.10.2014.
RST54 prj. is designed by Marine Engineering Bureau.
According to the inclining test results of the head series' vessel, her river deadweight is 5745 t at draught 3.60 m. This is a record value for "Volgo-Don Max" vessels.
The character feature of the new concepts is "expanding" narrow places of inland water transport by using new technical decisions. Saying in 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. Usage of RST54 combined vessels provides both directions cargo transportation (oil cargoes towards one direction and dry cargoes towards back direction); that should allow decrease highways rate due to re-forwarding some cargoes from road to water transportation. Such re-forwarded cargoes include passenger cars, that usually are brought 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.
RRR class notation is M-PR2.5 (ice30) A.
As other mixed river-sea going tankers designed by marine Engineering Bureau, RST54 vessels use full-turn rudder propellers as single movement and manoeuvre unit.
RST54 vessels satisfy Volga-Don Canal dimensions such as Volgo-Balt Way one. Vessel's overall length is of 140.85 m, breadth is of 16.60 m, depth is of 5.00 m. She belongs to the "Volgo-Don Max" class.
Tanker cargoes with flashpoint restriction for 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 crushed stone 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 (270-350 ones).
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 kW bow thruster.
Speed (due to the draught of 3.6 m and 85% of ME power) is 11.0 kn.
Ship's electric power plant consists of three 296 kW diesel-generators, and 62 kW emergency diesel-generator.
Crew consists of 12 people (14 + 1 places).
Vessel's autonomy is of 20 days (due to fuel, water and provision reserves).
