Multi-purpose dry-cargo vessel "Nefrit" of DCV36 project for VBTH holding was launched
On August 2, 2011 the sixth multi-purpose sea dry-cargo vessel of DCV36 project (building No. is of QHS-305) was launched at Qingdao Hyundai Shipbuilding Co. Shipyard (Qingdao, China).
Holding VBTH is a customer which ordered vessels' series of DCV36 prj. International transport group Universal Cargo Logistics Holding is a majority stockholder of VBTH holding. Universal Cargo Logistics Holding consolidates a group of Russian navigation (North Western Shipping Company, Volga Shipping Company, VF Tanker etc,), stevedoring and shipbuilding companies (Nevskiy Shipyard, Oka Shipyard, Borremphlot etc.).
Supervision of vessel's building is carried out by group of specialists of holding under the direction of Oleg Firsov.
DCV36 prj. is worked out by Marine Engineering Bureau.
Unlike previous dry cargo vessels series, which have been built for the holding according to the RSD44 and RDS49 projects, DCV36 project was a seagoing vessel of unrestricted sailing region from the very beginning. This project has corresponding safety factor, thickness of hull elements and main engines capacity.
DCV36 prj. is of striking innovation character type. Deadweight exceeding 5000 t for present-day single hold dry cargo vessel with calculated length less than 85 m was reached for the first time.
DCV36 prj. vessels are assigned for transportation of general, solid bulk, scrap, grain, coal, timber, heavy and large-sized cargoes, ISO 20' and 40' containers with height up to 9.5' (including ref containers), dangerous goods of 1.4S, 2, 3, 4, 5, 6.1, 8, 9 classes of IMDG Code and cargoes of category B of BC Code.
Project was designed for Russian Maritime Register of Shipping class notation of the project is of KM Ice 3 AUT1.
Vessel is single-deck motor-ship with unrestricted sailing region with single cargo hold, single screw, with forecastle and poop, with deck-house and engine-room located aft, with a double bottom and double sides in the cargo area, with removable grain bulkheads, with bulb fore and transom aft ends, with hatch covers of "folding" type of Cargotech company, with bow thruster.
Overall length is of 89.96 m, calculated length is of 84.89 m, breadth is of 14.5 m, depth is of 7.5 m, summer freeboard draught is of 6.40, deadweight for this draught is of 5206 t.
Cargo hold is designed of the box-shaped smooth-wall type, convenient for carrying out the freight works and placing a cargo without stowing. The cargo hold's sizes are of 60.0x11.50x9.20 m; that ensures placing 3 tiers of 9.5' containers or large-sized cargoes. Cargo holds capacity is of 6230 cub.m.
Double bottom is designed for distributed load intensity of 14.0 t per sq.m and for bucket grab usage.
Vessel's hull is design for Ice3 ice category for operation in Baltic and White Seas during whole year. Hull's theoretical forms, ice passability and hull's strength, main engine capacity fully satisfy the new requirements of Finnish-Swedish Ice Regulation.
Proceeding from results of resistance calculation methods (cruising speed of 12 kn was achieved) medium-speed diesel MAK 8M25C was chosen as main engine. This diesel has maximum specification continuous capacity of 2640 kW with speed of 750 rpm. Main engine use heavy fuel oil with viscosity of 380 cSt.
Speed of the lead vessel "Ametist" was of 12.8 with 90% usage of main engine capacity during running test. This result corresponds the full-load speed of 12.1 kn. For information: running test fully confirmed the results of predictive calculation of CFD modeling (expected speed during running test with usage of 90% ME capacity was 12.7 kn according to the calculation).
It is interesting to mark that front nozzles are supposed to be used for increasing of vessel's cruising speed in cargo condition and in ballast condition by approximately 0.2 knots in future.
Heavy fuel stores are placed in deep-tanks in area of the ER fore bulkhead.
Autonomy is of 25 days.
For improvement of vessel's controllability at low speeds, during passing narrow waters and mooring the 170 kWt capacity bow thruster of the "screw in a tube" type with a fixed-pitch propeller is foreseen.
For crew accommodation (10 persons) 2 single block-cabins and 8 single cabins with individual sanitary unit and shower are provided. Double cabin for students and single cabin for pilot are foreseen. Total number of persons' places onboard is of 13.
Keel of the lead vessel of the series "Ametist" (building No is QHS - 301) was laid down on 16.11.09. She was launched on 17.05.10.
Keel of the second vessel in the series "Agat" (building No is QHS - 302) was laid down on 03.12.09. She was launched on 15.06.10.
Keel of the third vessel in the series "Biryuza" (building No is QHS - 303) was laid down on 23.12.09. She was launched on 14.07.10.
Keel of the fourth vessel in the series "Lazurit" (building No is QHS - 304) was laid down on 15.01.10. She was launched on 04.09.10.
Keel of the fifth vessel in the series "Malakhit" (building No is QHS - 305) was laid down on 02.04.10. She was launched on 20.12.10.
Keel of the sixth vessel in the series "Nefrit" (building No is QHS - 306) was laid down on 04.05.10. It is supposed to launch the vessel in February, 2011.
Keel of the seventh vessel in the series (building No is QHS - 307) was laid down on 19.07.10.
Keel of the eighth vessel in the series (building No is QHS - 308) was laid down on 13.09.10.
Keel of the ninth vessel in the series (building No is QHS - 309) was laid down on 02.12.10.
Keel of the tenth vessel in the series (building No is QHS - 310) was laid down on 28.02.1.
