Raim Alekperov shipping company accepted into operation fourth dry-cargo vessel of "Azov max" class
On June, 25, 2008 "ALBROS" shipping company (Raim Alekperov is a general director of the company) accepted into operation new dry-cargo vessel "Azov Concord" with deadweight of 8975 tons.
The vessel was built at "Aksoy Shipyard", Gelibolu (Turkey).
"Azov Concord" is the fourth in the series of multi-purpose dry-cargo motorships of Marine Engineering Bureau (MEB) RSD12 prj. (conception of "Azov XL").
This vessel belongs to "Azov Max" type due to MEB internal classification. Principal particulars (overall length is of 142.00 m, overall width is of 18.00 m) are defined by sailing conditions of shallow water at Russian Azov ports without sailing through locks of Volga-Don canal.
The vessel is optimized for work with draughts of 3.8-4.5 m. With draught of 4.77 m deadweight is of 8020 tons, with draught of 4.50 m deadweight is of 7400 tons.
Cargo transportations' increasing through shallow water ports of Azov sea (Taganrog, Mariupol, Yeysk, Rostov-on-Don, Berdyansk and others) caused necessity to design the project of the dry-cargo vessel adapted for operation conditions in the mentioned pool.
The basic feature of Azov Sea and its ports is small depth of fairways and near ports' waterside. RSD12 prj. vessel was designed to get maximum deadweight and at the same time to get good enough sea-going and operational characteristics for transportation cargoes from the ports of Azov Sea to the ports of Europe, Asia Minor and Northern Africa.
Absence of requirements on an above-water dimension has allowed to develop essentially more aesthetic high aft superstructure, than on vessels of the river-sea type.
The dry cargo vessel is assigned for transportation of general, bulk, timber, grain and large-sized cargoes, 8'.5 and 9' ISO containers, dangerous goods of 1.4S, 2, 3, 4, 5, 6, 8, 9 classes of IMDG Code and cargoes of category B of BC Code.
Sea draught is of 5.187 m. with deadweight of 8975 tons. This is a feature of "Azov Concord". Three first vessels of series have maximal draught of 4.77m. with deadweight of 8020 tons (for 955 tons smaller).
The vessel has four holds with total capacity of 10930 cub.m. All holds are of equal sizes and capacity, box-shaped, smooth-wall, convenient for carrying out the freight works and placing a cargo without shifting. The cargo holds' size is 24.70x13.2x8.37 m that allows to arrange three levels of containers with height up to 9'. Holds are provided with hatch covers of "folding" type which can allow to arrange timber cargo with height of 2.5 m or one level of containers with maximum weight.
The double bottom is designed for distributed load intensity of 10.0 t/sq.m that allows to transport heavy metal products, and also allow to use a bucket grab with cargo-lifting capacity 16 tons.
Longitudinal framing system was used for deck, sides and bottom at the middle part of the vessel. At the same time transverse frame value was increased and longitudinal one was decreased. All the changes provide more full participation of shell plate in the overall bending, also better local loading's resistance during mooring and keeping of comprehensible appearance.
Russian Maritime Register of Shipping class is of KM Ice1 R2 AUT1.
Movement and maneuverability of the vessel is provided by two stern full-circle rudder propellers with variable-pitch propeller without nozzles. The drive from main engines to rudder propellers is carried out through mechanical Z-gearing.
Vessel's cruising speed is of 11.0 kn.
Proceeding from results of resistance definition by CFD simulation methods medium-speed diesels were chose as main engines with maximum specification continuous capacity of 2x1520 kW. Main engines use heavy fuel oil with viscosity of 380 cSt.
Heavy fuel stores are placed in deep-tanks in area of the ER fore bulkhead.
Tanks are separated by double bottom and double sides from outside water, thus excluding contact of heavy fuel with outside water.
The dry cargo vessel electric plant due to using of variable-pitch propellers consists of two shaft generators with capacity of 400 kW each, and also diesel - generators with capacity of 2x146 kW and one emergency diesel-generator with capacity of 81 kW.
The vertical deep-tanks placed between holds are used as ballast tanks. Deep-tanks' usage allowed to exclude under-deck "pockets" in holds. Thus allowed to place cargoes in the holds without shifting and improve conditions of stripping the holds.
Deep-tanks and large enough double sides allowed to mount dry compartments in the double bottom, but without using them as ballast tanks. It decreases weight of double bottom's metal construction and increases a life time of anticorrosive covering. It is necessary to mark, that double bottom's compartments are the least maintainable and excluding of taking ballast in them gives real economic benefit during carrying out the surveys and vessel's repair in the further operation.
Total ballast tanks capacity is of 3130 cub. m. Double side's breadth is of 2400 mm. Double bottom's height is of 1200 mm.
Bow thruster capacity is of 216 kWt.
Crew consists of 14 persons. Autonomy is of 20 day.
Keel of "Azov Concord" (building number is of H-33) was laid down on 30.12.06. She was launched on 01.03.08. She was put into operation on 25.06.08.
There are four vessels in the series. First three vessels of "Azov Max" class are being successfully operated by "ALBROS" shipping company.
