The seventh tanker "Shofket Alikperova" of "Volgo-Don Max. class" type (RST22M prj.) was solemn launched for Palmali Group of Companies
On April 30, the seventh river-sea going tanker of "Volgo-Don Max. class" type (RST22M prj.) with deadweight about 7100 t was launched in Turkey. Vessel's name is "Shofket Alikperova", her building No. is of 18. Totally 14 vessels may be included in the RST22M series (plus 5 optional ones).
Palmali Group of Companies is a Customer.
RST22M project ("Armada" third series) is designed by the Marine Engineering Bureau (MEB).
Other seven vessels (plus 5 optional ones) are under building at Turket Shipyard at Tuzla and Armada Shipyard at Izmit.
This moment 5 tankers are under construction now at the Turket Shipyard (building Nos. 078, 079, 080, 081, 082). There were 2 official keel's laying (on 02.10.2013 for Building No. 078 and on 18.11.2013 for Building No. 079. The first vessel launching is expected in June, 2014 and putting into operation at the year end. Putting into operation of other 4 tankers is expected in 2015. There is ability of series prolongation for 5 optional vessels.
Armada Shipyard (included in Palmali Group of Companies) are carrying out metal cutting for its RST22M lead vessel (building No. 001) since 11.04.2014. Term of the first tanker delivery at this new shipyard is May, 2015. After putting into construction 2 tankers of RST22M type (building Nos. oo1 and 002) shipyard is going to commence building of absolutely new RST12 series of "Volgo-Don Max. class" type. This vessel has enhanced river function with keeping well known Armada decisions, such as usage of full-turn rudder propellers.
Thus, it is supposed that 14 tankers (plus 5 optional ones) should be built for Palmali Group of Companies. These tankers are of "Volgo-Don Max. class" of RST22M prj.
The new series vessels are logical continuation of 005RST01 project tankers known as first series "Armada" which were designed by the Marine Engineering Bureau for Palmali Group of companies and which were built on "SELAH" and "ADA" shipyards in Tuzla (Turkey) in 2002-2006 and modification of second series tankers of RST22 project which were built on "Krasnoe Sormovo" shipyard (Nizhny Novgorod) in 2008-2009. Total 10 vessels of "Armada" type of 005RST01 project and 7 vessels of "New Armada" type of RST22 project were built (5 tankers of them were built for Palmali group of companies).
21 vessels of "Armada" type tankers of the first series and "New Armada" type tankers of the second and the third series are successfully operated on the river-sea transportation from Russian river ports and sea transportations in Caspian, Black, Mediterranean, Baltic and North Seas, including voyages around Europe and to Irish Sea in winter. They transport crude oil, masout, diesel fuel, other petroleum products and vegetable oils.
Using full-circle rudder propellers as movement and manoeuvre facilities, using submersible pumps, absence of longitudinal bulkhead in CL, full absence of a framing in cargo tanks, developed trunk are characteristic features of RST22M, RST22 and 005RST01 vessels' projects.
Vessels satisfy dimensions of the Volga-Don Canal and Volga-Baltic Way. Overall RST22M prj. vessel length is of 139.95 m, breadth is of 16.6 m, depth is of 6.0 m.
Vessels belong to "Volga-Don Max" tankers' type.
New project tankers have increased sea function, increased for 750 tons deadweight at sea conditions and increased total cargo tanks capacity with keeping river possibilities in comparison with first series vessels of "Armada" type.
Vessels satisfy all new international requirements for transportation of vegetable oils, including two-compartment unsinkability.
Special requirements of the Russian and world petroleum companies, additional ecological limitations "ECO PROJECT" (ECO-S) class were taken into consideration during designing.
Hull's theoretical forms were defined using calculating hydromechanics methods (CFD modeling).
Total capacity of six cargo tanks and two slop ones is of 8089 cub. m, deadweight is about 7103 tons when sea draught is of 4.60 m. Deadweight is about 4706 tons when river draught is of 3.60 m. Cruising speed is of 10.5 knots.
Two medium-speed diesels (main engine) of 1200 kWt each use heavy fuel oil with viscosity of IFO380.
Lead vessel "Mubariz Ibragimov" showed:
1. During running test (ballast condition) vessel's cruising speed was of 12.1 kn with 85% usage of main engines' capacity.
2. Vessel's speed was of 11.5-12.0 kn during ballast run (draught is of 3.20 m), with head wind of 12 meters per second and wave's height of 1.5-2.0 m.
3. Vessel's speed was of 12.3-12.5 kn during cargo run, with following wind of 25-30 meters per second and following sea with wave's height of 6-7 m.
4. Vessel's speed was of 9.9-10.2 kn during cargo run, with head wind of 13-14 meters per second and head sea with wave's height of 1.5-2.0 m and with counter flow of 3 kn.
5. Vessel's speed was of 11 kn during cargo run on still water with draught of 4.45 m.
RST22M vessel's project Russian Maritime Register of shipping class notation is of KM Ice 2 R1 AUT1 COMBO oil tanker/chemical tanker type 2 (vegetable oil) (ESP) ECO-S.
In comparison with the second series of "Armada" type, all new requirements of International Conventions and Register Rules (MARPOL requirements due to access to double side and double bottom spaces and others), were taken into consideration. There were mounted six cargo pumps with capacity of 200 cub.m/h instead of six cargo pumps with capacity of 150 cub.m/h. This change allowed to reduce time of cargo operations on 2.5 hour. Submersible ballast pumps were mounted (as it was in basic project), stern manifold was excluded and arrangement of equipment in engine room was significantly changed because of exclusion of function of dismounting of full-circle rudder propellers through the upper deck.
