Baku Shipyard started to cut steel for the third and the fourth RST12C oil/chemical tanker of 7875 t deadweight



On 21.05.2019 Baku Shipyard (director is Imanverdy Gasanov) started to cut steel for the third and the fourth RST12C oil/chemical tanker of 7875 t deadweight (building No. are 112 and 113) due to order of CJSE "Azerbaijan Caspian Shipping Company".
 
RST12C prj. was developed by Marine Engineering Bureau.
 
The readiness for the head RST12C oil/chemical tanker "Lachin" of 7875 t deadweight (building No. 110) is 86%. She was launched 21.02.19. Putting into operation is planned for August, 2019.
 
The readiness for the second tanker "Kelbajar" (building No. 111) is 60%. Putting into operation is planned in 2020.
 
New RST12C tanker has a boosted "Caspian" function:
 
• 7875 t deadweight at Caspian draught of 4.50 m (RST27 tanker has 7022 t deadweight), increased is 853 t;
• capacity of cargo tanks is foreseen for oil and oil products at Caspian Region; capacity is increased by trunk raising up to 9190 m³ (RST27 has 8100 m³), i.e. there is 1090 m³ increase.
 
Russian Maritime Register of Shipping class notation is KM Ice1 R2-RSN(4.5) AUT1-ICS VCS ECO-S OMBO Oil tanker/Chemical tanker type 2 (ESP).
 
Like the other mixed river-sea tankers of the Marine Engineering Bureau, the RST27 vessels use full turned rudder propeller as a single control/movement mean, has a developed trunk, uses submersible pumps; there are no CL longitudinal bulkhead and framing within cargo tanks.
 
RST12C vessels satisfy to the dimensions of the Volga-Don Shipping Canal and the Volga-Baltic Way. The overall length is 141.00 m, width is 16.9 m, depth is 6.0 m, trunk height is 1.75 m. RST12C vessels are of tankers "Volga-Don Max" class.
 
While designing it was taken into account the special requirements of Russian and world oil companies, additional environmental restrictions of the Russian Maritime Register of Shipping "ECO PROJECT" (ECO-S) class.
 
RST12C vessel is designed for transportation of crude oil and oil products with density of up to 1.015 t/m³, including gasoline, without restriction on the flash point, ensuring the carriage of goods with a temperature of 50°C, as well as chemical cargoes:
 
Methyl alcohol;
Ethyl tert-butyl ether;
Ethylene glycol;
Methyl tert-butyl ether;
Acetone;
Ethyl alcohol;
Isopropyl alcohol;
Calcium lignosulphonate solution;
Ethyl acetate;
Hexane (all isomers);
Octanol (all isomers);
Sodium hydroxide solution;
Toluene;
Urea/ammonium nitrate solution;
Xylenes;
Diethylene glycol.
 
Simultaneously transportation of 2 types of cargo is provided.
 
The capacity of six cargo tanks and two slop tanks is 9190 m³, marine deadweight is 7875 t while draught is 4.54 m, river deadweight is with 5447 t, operational speed is 10.0 kn.
 
The cargo system is designed for simultaneous transportation of two types of cargo, cargo pumps are 6 x 200 m³/h. Two auxiliary steam boilers of 2.5 t/h capacity are installed.
 
Two medium-speed diesels (main engines) of 1200 kW each use heavy fuel oil with viscosity IFO380. There is 230 kW bow thruster.
 
Electrical plant consists of three 350 kW diesel-generators and emergency-staying 150 kW diesel-generator.
 
Crew consists of 11 persons (14 places + pilot).
 
Autonomy (marine/river) is 20/12 days.
 
Keel of the head RST12C tanker "Lachin" (building No. 110) was laid down on 09.02.17. She was launched 21.02.19. Putting into operation is planned for August, 2019.
Keel of the second tanker (building No. 111) was laid down on 18.04.18.
