The keel was laid down for the 2nd in Russia RSD59 dry cargo vessel of 8144 DWT, that meet to increased environmental requirements of the DE-Tier III

On 26.05.21 the keel of the second in Russia multipurpose RSD59 dry cargo vessel of 8144 t deadweight (building number 5917), that meet to increased environmental requirements of the IMO TIER III (DE-Tier III) for emissions into the atmosphere, was laid down for the Idel company.
 
PJSE "State Leasing Transport Company" is a Customer, shipping company "Idel" is a lessee.
 
The RSD59 prj. was designed by Marine Engineering Bureau.
 
For marine engines, in accordance with the International Convention MARPOL, since 2000, they have been limiting the emissions of nitrogen oxides (NOx) into the atmosphere. For ships operating in IMO emission control zones, which are relevant for vessels of limited navigation areas and mixed river-sea navigation, for example, in the Baltic and North Seas and laid down from January 1, 2021, the new TIER III standard came into force.
 
To meet its strict enough requirements on the vessels of the RSD59 project of the Oka shipyard, newly built for SLTC, an exhaust gas cleaning system was used to reduce NOx emissions, based on the principle of selective catalytic reduction (SCR) to remove nitrogen oxides (NOx). The SCR system reduces the level of nitrogen oxides in the exhaust gas from the engine using catalytic elements and a reagent. During the process, a reagent in the form of an aqueous urea solution is injected into the exhaust gas stream. The water from the urea solution evaporates when it is injected into the hot exhaust gas.
 
The nitrogen obtained in this way is released into the atmosphere, and the water is cooled and goes overboard.
 
Oka Shipyard has signed contract for more 18 RSD59 vessels (the first five are for the Petrotrans shipping company, next ten are for the "Astrol" shipping company, plus three more newly contracted). The first ten vessels have been accepted for operation.
 
RSD59 vessels refer to the "Volga-Don Max" type due to MEB internal classification. They have maximum possible dimensions for the 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 IMSBC Code. Sailing regions are Mediterranean, Caspian, Black, Baltic, White, North Seas, including voyages around Europe and to Irish Sea in winter.
 
The new dry-cargo project RSD59, which is constructed in "super-full" ship lines with two dry cargo holds, one of which has a record length for Volgo-Don Max vessels, is the successor of the three-hold RSD49 series.
 
Advantages of the RSD59 project in comparison with the best of the previously constructed dry cargo vessels of the Volga-Don Max class of the RSD49 project (by the example of m/v "Pola Fiva" with increased marine function):
 
• the existence of a long L = 77.35 m hold (RSD49 vessel has L = 52 m cargo hold ) that allows transportation of oversized and heavy cargo; this is relevant for the market of the Caspian region countries;
• the hold's height is increased up to 9000 mm, that is 620 mm bigger than for RSD49 project. Such height allows to load 9'6'' containers ("high cube containers"), 3 ones in single stack;
• deadweight at draught of 3.60 m is 5320 t (RSD49 has 4507 t), increase is 813 t;
• deadweight at a draught of 4.20 m 6944 tons (RSD49 project has 6021 t), increased by 923 t;
• deadweight at the maximum draught of 4.706 m is 8144 t (RSD49 has 7143 t at maximum draught of 4.70 m), increase is 1000 t;
• removable type hatch covers are installed. Opening and closing of each section is operated with the help of a special frame crane, which is located in the area of the front bulkhead of the residential superstructure;
• movement and controllability are provided by two rudder propeller units (better maneuverability in the narrow waters, more cargo space due to the reduction of size of engine room).
 
The project is designed for a class notation KM Ice2(hull; machinery) R2 AUT1-ICS LI BWM(T) CONT (deck, cargo holds Nos.1,2) DG (bulk, pack) DE-Tier III A-Thruster(M) of Russian Maritime Register of Shipping and meets all the requirements of international conventions acted at the moment of the vessel's keel laying.
 
In this case, RSD59 vessels' deadweight is the largest for dry cargo vessels satisfying the dimensions of the Volga-Don Shipping Channel.
 
For characteristic for the VDSC draught of 3.60 m, river deadweight is 5320 t; the largest marine deadweight for draught 4.706 m is 8144.
 
The maximum length is 141.0 m, the overall width is 16.98 m, depth is 6.00 m.
 
The capacity of cargo holds is 11400 cubic m.
 
Both cargo holds are box-shaped, smooth-walled, and convenient at cargo operations and placing the goods without stowage. Their dimensions are 77.35 x 12.25 x 9.0 m and 27.03 x 12.25 x 9.0 m.
 
The operating speed is 10.5 knots.
 
Two medium-speed diesels (main engine) of 1100 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.
 
Sea sailing autonomy is 20 day.
 
Crew consists of 11 people, total places onboard are 14. Sanitary and pilot cabins are provided.
 
Designed vessel hull's life term is 24 years. The double bottom is designed for distributed load with intensity of 12 tons per square meter, and also allows to use 16 t bucket grab.
