The hull of the lead tanker of RST25 project was rolled onto building berth at "Brothers Nobel Shipyard"
On May 20, 2011 lead tanker of RST25 project with deadweight in sea/river is of 6610/5130 tons with increased ecological standard was rolled onto building berth at "Brothers Nobel Shipyard" (Larisa Starostina is manage director).
Shipyard is included in "Moscow River Steamship Company" (Constantine Anisimov is a general director) that ordered the series of 3 river-sea going tankers.
Project RST25 was designed by Marine Engineering Bureau.
Vessel of RST25 prj. is being built for Russian River Register (RRR) class notation of M-SP 4.5 (ice 40) A ECO3.
Special requirements of the Russian and world petroleum companies, additional ecological limitations of RRR ECO3 class ("CLEAN DESIGN" according to DNV classification) were taken into consideration during designing of RST25 prj. tankers.
For the first time such class notation was assign in Russia to RST22 prj. tanker built in 2008.
Vessels are assigned for river-sea and sea transportation of crude oil and oil products, including benzine, without flash point restrictions, with providing of cargo transportation with keeping of 50 degr. C. temperature. Simultaneous transportation of 2 cargo kinds is ensured.
Using full-circle rudder propellers as movement and manoeuvre facilities, using submersible pump, full absence of a framing in cargo tanks, enlarged trunk are characteristic features of RST25 project vessel. These vessels have no longitudinal bulkhead in CL.
Vessel satisfies the dimensions of the Volga-Don canal and Volga-Baltic way. Overall RST25 prj. vessel length is of 139.99 m, breadth is of 16.6 m, depth is of 5.5 m.
Vessels belong to "Volga-Don Max" tankers' type.
New project tanker have increased river function, increased deadweight by 410 tons in river conditions and increased total cargo tanks capacity with keeping sea possibilities in comparison with vessels of "Armada" type.
Total capacity of six cargo tanks and two slop ones is of 6990 cub. m, deadweight is about 6610 tons when sea draught is of 4.17 m. Deadweight is about 5130 tons when river draught is of 3.60 m. Cruising speed is of 10.5 knots.
Two medium-speed diesels (main engine) of 1200 kWt each use heavy fuel oil with viscosity of IFO380.
Autonomy is of 20 days.
Crew consists of 12 persons (14 places).
Lead vessel RST25 keel was laid down on 21.12.10.
