Seven new RSD49 dry cargo vessels of "Neva-Leader" type have transported 1 million tons of cargo


According to the statement of press-service of OJSE "North-Western Shipping Company" (NWSC), the amount of cargo transportation carried out by seven RSD49 dry cargo vessels of "Neva-Leader" type reached 1 million tons. Transported cargoes include grain, fertilizer and ferrous metals, also large-sized cargoes. In particular, after end of 2012 these vessels have effected 14 voyages with large-sized equipment, and from January till September 2014 they fulfilled 7 equipment transportations from Southern and Northern Europe to Caspian Sea, Povolzh'e (regions of Middle and Lower Reaches of Volga River), St.-Petersburg.
 
The nearest months RSD49 dry cargo vessels built at Nevskiy Shipyard, are going to be used for transportation of grain, metal and fertilizers between Russian and foreign ports at southern seas and at Baltic Sea.
 
New generation RSD49 dry cargo vessels with deadweight more than 7000 t are of the biggest Russian river-sea dry cargo vessels that satisfy Volga-Don Canal dimensions. Vessels have 3 cargo holds, the biggest middle hold is 52 m long. This feature is highly required for large-sized cargo transportation. It is expected that the whole series at the Nevskiy Shipyard will be completed in 2015.
 
Putting new vessels into operation and eliminating some old vessels let NWSC to decrease the mean fleet age from 18 to 14 years', - was told in the post.
 
RSD49 project was designed by the Marine Engineering Bureau (MEB).
 
RSD49 vessels refer to the "Volga-Don Max" type due to MEB internal classification. They have maximum possible dimensions for Volga-Don Canal.
 
Vessels of the series can be operated for transportations of general, bulk, timber, grain and large-sized cargoes, dangerous goods of 1.4S, 2, 3, 4, 5, 6.1, 8, 9 classes of IMDG Code and cargoes of category B of BC Code. Sailing regions are Mediterranean, Caspian, Black, Baltic, White, North Seas, including voyages around Europe and to Irish Sea in winter.
 
RSD49 prj. vessel's feature is a big middle hold of 52 m long as diversity from all other "Volga-Don Max" type projects designed by MEB. This hold allows to transport large-sized cargoes in direct voyages from Europe to Caspian Sea; such point should significantly increase economic effect of vessels' operation.
 
Vessel was designed for Russian Maritime Register of Shipping class notation of KM Ice2 R2 AUT1-C. The project satisfies all the requirements of international conventions.
 
RSD49 prj. vessels' are the biggest ones among the dry cargo vessels that satisfy Volga-Don canal dimensions for today such as prototype vessels of RSD19 prj.
 
With characterized draught of 3.6 m in Volga-Don Canal deadweight is about 4520 t, maximal deadweight in the sea with draught of 4.70 m is 7143 t.
 
Overall length is 139.95 m, overall breadth is 16.70 m, breadth without side fenders is 16.50 m, depth is 6.00 m.
 
Summarized capacity of cargo holds is 10920 cub. m.
 
All holds are box-shaped, smooth-wall, convenient for carrying out the freight works and placing a cargo without shifting. The cargo holds' sizes are 26.0x12.7x8.4 (hold No. 1), 52.00x12.7x8.4 m (hold Nos. 2), 27.3x12.7x8.4 (hold No.3).
 
Cargo holds are equipped with sectional hatch covers of Folding type of Cargotech with possibility of 100% opening.
 
Operational speed is 11.5 kn.
 
Two medium-speed diesels (main engine) of 1200 kW each use heavy fuel oil with viscosity of IFO380. Heavy fuel stores are placed in deep-tanks in area of the ER fore bulkhead, separated from outside water by double bottom and double sides.
 
Movement and manoeuvrability of the vessel is provided by two fixed-pitch propellers in nozzles with diameter 2500 mm, two hanging balanced rudders and single bow thruster with capacity 200 kW.
 
Modern computing methods of hydrodynamics were used at vessel designing that allowed to find an optimum combination of propulsion-rudder system elements and hull forms. Defined combination provides high running qualities of the vessel. It also provides propulsion coefficient above 0.6 during sailing at full draught and maximum speed.
 
Towing and self-running test of vessel model were carried out to check project decisions and definitions of running qualities in big test pool at CRI named for academic A.N. Krylov. Carried out tests fully confirmed earlier received CFD simulation results.
 
Sea sailing autonomy is 20 day.
 
Crew consists of 10 persons (12 places). Sanitary cabin and pilot cabin are foreseen on vessel.
 
Designed vessel hull's life term is 24 years. The double bottom is designed for distributed load intensity 12 tons per square meter, and also allows to use 16 t bucket grab.
