Oka Shipyard launched the tenth tanker of RST27 prj.
On 28.05.13 Oka Shipyard in Navashino (Vladimir Kulikov is a director) launched the tenth serial tanker "VF Tanker - 20" of RST27 prj. of "Volgo-Don Max" type with sea/river deadweight of 7030/5428 tons (building No. is of 02710).
"V.F.Tanker" Shipping Company is a customer. Company is included in the VBTH Holding, international transport group Universal Cargo Logistics Holding (UCLH) 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 actually is of 7030/5428 t. Speed was of 11,7 knots during running test. Speed was of 11,7 knots during running test.
New project tanker has increased river function comparing with other MEB projects. River deadweight of RST27 prj. vessels is increased for 716 t comparing to Armadas, while:
• hull strength increasing (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.
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).
This forms also were investigated by model tests at the towage tank of CSRI named for academic A.N.Krylov. 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.
RST27 prj. vessels satisfy dimensions of the Volga-Don Canal and Volga-Baltic Way. Overall RST27 prj. 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 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 is about 5428 tons with river draught of 3.60 m. Cruising speed is of 10.5 knots.
Cargo system provides simultaneously transportation of 2 cargoes. Cargo pumps capacity is of 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 is 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).
Autonomy is of 20/12 days (sea/river).
RST27 prj. vessels satisfy the requirements of Russian Maritime Registry of Shipping due to class notation of KM Ice1 R2 AUT1-ICS OMBO VCS ECO-S Oil tanker (ESP).
Total 15 RST27 prj. tankers are going to be built at Oka shipyard.
