Russia: Oka Shipyard Splashes VF Tanker – 21
Oka Shipyard launched the eleventh serial tanker “VF Tanker – 21” of RST27 project on July 10. The vessel, owned by V.F.Tanker Shipping Company, pertains to “Volgo-Don Max” type and has sea/river deadweight of 7030/5428 tons (building No. is 02711).
The owner company is member of the VBTH Holding, international transport group Universal Cargo Logistics Holding (UCLH), which is a majority stockholder of VBTH holding. UCLH consolidates a group of Russian navigation, stevedoring and shipbuilding companies.
Project RST27 was designed by Marine Engineering Bureau.
Contract deadweight of 6980/5378 t was increased for “VF tanker-11” by 50 t and amounts to 7030/5428 t. The speed of 11.7 knots was achieved during running test.
New project tanker has increased river function comparing with other MEB projects. River deadweight of RST27 project vessels is increased for 716 t comparing to Armadas, while:
• increasing hull strength (vessel is of R2 sailing region, or region II due to old RS classification);
• practically keeping the same fuel consumption;
• keeping increased capacity of cargo tanks.
The hull’s theoretical forms are a result of scientific research carried out by Marine Engineering Bureau together with Digital Marine Technology in 2010 and were defined with the help of calculating hydromechanics methods (CFD modeling).
These forms were also investigated by model tests at the towage tank of CSRI named after academic A.N.Krylov. The experiment fully confirmed results of theoretical investigations.
As other river-sea going MEB tankers, RST27 prj. vessels use full-circle rudder propellers as single 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.
The vessels meet the requirements of the Russian Maritime Registry of Shipping due to class notation of KM Ice1 R2 AUT1-ICS OMBO VCS ECO-S Oil tanker (ESP).
RST27 prj. vessels satisfy dimensions of the Volga-Don Canal and Volga-Baltic Way. The overall RST27 prj. vessel length is 140.85 m, breadth is 16.6 m, while the depth amounts to 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 the design process. RST27 prj. 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 7030 tons with sea draught of 4.20 m. Deadweight equals to approximately 5428 tons with river draught of 3.60 m. Cruising speed of the vessel is 10.5 knots.
Cargo system provides simultaneous transportation of 2 cargoes. Cargo pumps capacity covers 6 x 200 cub. m/hour. Two auxiliary steam boilers (capacity of 2.5 t/hour each) are installed onboard.
Two medium-speed diesels (main engine) of 1200 kWt each use heavy fuel oil with viscosity of IFO380. Bow thruster has the capacity of 230 kWt. Electrical plant consists of three 292 kWt diesel-generators and emergency-staying 136 kWt diesel-generator.
Crew consists of 12 persons (14 places + pilot) and the vessel has the autonomy of spending 20/12 days at sea/river respectively.
A total of 15 RST27 project tankers are going to be built at Oka shipyard.
