Kherson shipyard laid down keel of head tanker of RST27 prj. with sea/river deadweight of 6980/5378 tons
On October 21, 2011 Kherson shipyard (Vasiliy Fedin is a general director) laid down keel of head "Volgo-Don Max" type tanker of RST27 prj. with sea/river deadweight of 6980/5378 tons.
Project RST27 was designed by Marine Engineering Bureau. Hull's theoretical forms are a result of scientific research carried out 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.
New project tanker has increased river function comparing with other MEB projects. River deadweight of RST27 prj. vessels is increased for 700 t comparing to Armadas, while enhanced cargo tanks capacity and enhanced hull's strength are kept (vessel is of R2 sailing region, or II region due to old RS classification).
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 6980 tons with sea draught of 4.20 m. Deadweight is about 5378 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).
RST27 prj. 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).
Total 3 RST27 prj. tankers are going to be built at Kherson shipyard.
Keel of RST27 prj. head vessel (at Kherson shipyard) was laid down on 21.10.11.
