Russia: Oka Shipyard Launches VF Tanker-14

Oka Shipyard  launched the fourth built by shipyard tanker “VF Tanker – 14” of RST27 prj. with sea/river deadweight of 7030/5428 tons (building No. 02704) on 23.08.12.

The Shipyard should deliver four vessels by the contract, but according to the actual rate, six tankers from new series would be built.

“V.F.Tanker” Shipping Company (Sergey Bryzgalov is a managing director) 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 11.7 knots.

The Shipyard should deliver four vessels by the contract, but according to the actual rate, six tankers from new series would be built:

• 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).

Then 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.

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 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 10.0 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).
