This vessel is of "Volgo-Don Max" type; her deadweight is about 6610 t. Unlike the first two vessels this one is modified and is building as oil/chemical tanker type 2; she will be able to transport vegetable oils and chemicals in bulk in addition to usual oil cargo. Volgotrans Company is a Customer for this vessel and for the next one (keel laying is supposed on the 7th of April).
 
Project RST25 was designed by Marine Engineering Bureau.
 
Five RST25 vessels are under operation now. They were built by Brothers Nobel Shipyard in Rybinsk and Zhelenodolsk Shipyard named after A.M. Gorkiy. Lotos shipyard is going to hand more two ones to the Moscow River Shipping Company in spring of of 2016. Tankers successfully work at inner waterways, at Caspian, Black and Mediterranean Seas.
 
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 tankers.
 
Vessel is 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 60°C temperature; also carriage ov vegetable oils and chemicals in bulk are foreseen. Simultaneous transportation of 2 cargo kinds is ensured including the following chemicals:
 
• Palm oil;
• Sunflower seed oil;

Vessels belong to "Volga-Don Max" tankers' type.
 
New project tanker have increased river function, increased deadweight by 410 tons in river conditions 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 kW each use heavy fuel oil with viscosity of IFO380.
 
Autonomy is of 20 days.
 
Crew consists of 12 persons (14 places).
