First 14 "super-full" RST27 tankers owns by "V.F. Tanker" Company reach 5 years old



As to information from press-service of "V.F.Tanker" Company (is included into UCL Holding), its first 14 RST27 vessels built in 2012 are going to pass the first class survey this year. Aim of the class survey is to confirm class after 5-year operational period. Scheduled repairing with docking will be effecting at bases of ship-repairing enterprise Hellenika Ltd. in Varna and Burgas under supervision of surveyors of Russian Maritime register of shipping. Works include inspection of vessel's hull, full cleaning and painting of hull surface; maintenance of mechanisms and systems, propeller-rudder complex, main engines, diesel-generators, cargo system, navigation equipment. In average, 27 days are planned for each vessel to complete such scope of works.
 
This moment, 2 vessels ("VF Tanker-13" and "VF Tanker-6") has already passed all mandatory procedures in fully correspondence with RS rules.
 
Britain Royal Institution of Naval Architects included RST27 in the list of the best vessels of the year (Significant Ships of 2012 and Significant Ships of 2013).
 
Series of RST27 tankers with an increased block coefficient is the biggest in newest history (since 1991) of national shipbuilding; during period from 2012, 35 vessels has been built and accepted into operation. 22 ones from this amount (63%) are under management of the "V.F. Tanker" Company. Company's vessels were constructed both at Krasnoe Sormovo Shipyard (Nizhniy Novgorod) and at Oka Shipyard (Navashino, region of Nizhniy Novgorod).
 
RST27 vessels have the record block coefficient 0.93; the head vessel showed speed of 11.7 kn during trials at running line with main engines power of 2100 kW (87.5% of full output) and fore/aft draughts 3.2/3.3 m.
 
Thus the contract deadweight of 6980/5378 is increased for 42 t, contract speed is increased more than 1 kn.
 
New project tanker has increased river function comparing with other MEB projects. River deadweight of RST27 vessels is increased for 732 t comparing to Armadas, while:
 
• increased hull's strength (vessel is of R2 sailing region, or II region due to old RS classification);
• practically keeping the same fuel consumption;
• keeping increase capacity of cargo tanks.
 
Russian Maritime Registry of Shipping class notation is - KM Ice1 R2 AUT1-ICS OMBO VCS ECO-S Oil tanker/Chemical tanker type 2 (ESP).
 
As other river-sea going MEB tankers, RST27 vessels use full-turn rudder propellers as single movement and maneuver unit. They have increased trunk and use submersible cargo pumps. They have no longitudinal bulkhead in CL and no framing in cargo tanks.
 
RST27 vessels satisfy dimensions of the Volga-Don Canal and Volga-Baltic Way. Overall RST27 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.
 
RST27 vessels are assigned for transportation of crude oil and oil products without flash point restrictions, also dangerous chemicals in bulk.
 
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.
 
Cargo system provides simultaneously transportation of 2 cargoes. Cargo pumps capacity is 6 x 200 cub. m/hour. Two auxiliary steam boilers (capacity 2.5 t/hour each) are installed onboard.
 
Two medium-speed diesels (main engine) of 1200 kW each use heavy fuel oil with viscosity IFO380.
 
There is 230 kW bow thruster.
 
Electrical plant consists of three 292 kW diesel-generators and emergency-staying 136 kW diesel-generator.
 
Crew consists of 12 persons (14 places + pilot).
 
Autonomy is of 20/12 days (marine/river).
 
"V.F. Tanker" Shipping Company is specialized for bulk cargoes transportation through inland water ways as well as at international lines. Company has 80 vessels under operational control; summarized deadweight of this fleet is bigger than 4000 thousand tons. Company is included in VBTH, shipping division of international transport group ACL.
