V.F.Tanker Shipping Company has put into operation the sixth tanker of Project RST27 named VF Tanker-6 (building No. 02006) with sea/river deadweight of 7022/5420 tons.
In total 10 RST27 project tankers should be built at Krasnoe Sormovo shipyard.
Project RST27 was designed by Marine Engineering Bureau.
New project tanker has increased river function comparing with other MEB projects. River deadweight of RST27 prj. vessels is increased for 732 t comparing to Armadas, while:
-enhanced hull’s strength (vessel is of R2 sailing region, or II region due to old RS classification);
-almost same fuel oil consumption;
-enhanced cargo tanks capacity keeping.
Hull’s theoretical forms are a result of scientific research carried out by Marine Engineering Bureau altogether with Digital Marine Technology in 2010 and were defined with help of calculating hydromechanics methods (CFD modeling). These forms also were investigated by model tests at the towage tank of CSRI named for academic A.N.Krylov. Experiments fully confirmed results of the theoretical investigations.
RST27 project vessels meet requirements of Russian Maritime Registry of Shipping due to class notation KM Ice1 R2 AUT1-ICS OMBO VCS ECO-S Oil tanker (ESP).
As other river-sea going MEB tankers RST27 prj. vessels use full-circle rudder propellers as united movement and manoeuvre facilities. They have increased trunk and use submersible cargo pumps. They have no longitudinal bulkhead in CL and no framing in cargo tanks.
RST27 project vessels satisfy dimensions of the Volga-Don Canal and Volga-Baltic Way. Overall RST27 project vessel length is of 140.85 m, breadth is of 16.6 m, depth is of 6.0 m. They belong to “Volgo-Don Max” class. Special requirements of the Russian and world petroleum companies, additional ecological RS limitations of “ECO PROJECT” (ECO-S) class were taken into consideration during designing. The vessels are assigned for transportation of crude oil and oil products, without flash point restrictions.
Total capacity of six cargo tanks and two slop ones is of 8100 cub. m, deadweight is about 7022 tons with sea draught of 4.20 m. Deadweight is about 5420 tons with river draught of 3.60 m. Cruising speed is of 11.0 knots. Two medium-speed diesels (main engine) of 1200 kW each use heavy fuel oil with viscosity of IFO380. Bow thruster is of 230 kW.
Crew consists of 12 persons (14 places + pilot).
Autonomy is of 20/12 days (sea/river).
