The keel of lead tanker of RST25 project was laid down at Zelenodolsk A.M. Gorky Shipyard
On April 22, 2011 the keel of lead tanker with deadweight of 6610/5130 in sea/river with increased ecological standard (RST25 project) was laid down at Zelenodolsk A.M. Gorky Shipyard (Renat Mistakhov is a general director).
Zelenodolsk A.M. Gorky Shipyard is included in holding company "Ak Bars". "Naphta-Invest" is a customer of the series consisted of two river-sea going tankers (plus three ones in option) of river-sea going type. The financing is carried out by "Ak Bars Leasing".
The keel of lead tanker of RST25 prj was laid down in the same time as the keel of new high-speed passenger vessel (A145 prj) was.
RST25 project is designed by the Marine Engineering Bureau (MEB).
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, and requirements of RRR ecological ECO3 class ("CLEAN DESIGN" according to DNV classification) were taken into consideration during designing of RST25 prj. tankers.
Such class notation was given to RST22 prj. tanker for the first time in Russia 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 degrees 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.
Vessels satisfy 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 for 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).
The keel of lead vessel of RST25 prj was laid down at OJSC "Zelenodolsk A.M. Gorky Shipyard" on 22.04.11. It is supposed to put the vessel into operation in 2012.
