Solemn ceremony of keel laying down procedure for lead multi-purpose buoy laying vessel of BLV02 project at OJSC Shipyard "Nizhegorodskiy Teplokhod"
On March 15, 2012 keel of lead multi-purpose buoy laying vessel of BLV02 project (building No. is of 902) was laid down during solemn ceremony at OJSC Shipyard "Nizhegorodskiy Teplokhod" (Sergey Konovalov is a director).
Federal state department "Rechvodput'" of Federal Agency of Marine and River Transport of RF Ministry of transport is a customer.
According to the contract it is supposed to build two vessels of BLV02 project for Volgo-Baltic and Belomorsk-Onega state navigation basin departments.
Project BLV02 was designed by Marine Engineering Bureau (MEB).
Buoy laying vessel is assigned for carrying following operations out:
• Conditional control of the fairway over internal waterways and port areas;
• Conditional control of fairway navigational protection and working of buoys' fires;
• Arrangement and removal of signs, and also their moving due to change of fairway borders;
• Service of navigational conditions signs and repair of the appropriate equipment.
Sailing regions are of Russian inland waterways with limitations; marine regions are established according to M-SP 3.5 navigation area. It is supposed to operate vessel in A1 sailing region according to radio equipment.
Vessel is steel, with single deck, self-propelled, twin-screw, with a forecastle and poop, with transom stern, with work deck at midship which allows to place simultaneously 4 BMS buoys, with aft arrangement of ER and deckhouse, with cargo crane that ensures buoys operating.
Vessels' characteristics are as follows:
Overall length is about 47.00 m;
Length between perpendiculars is of 40.49 m;
Overall breadth is of 10.50 m;
Breadth DWL is of 9.70 m;
Depth at midship is of 3.50 m;
Draught (DWL/maximum) is of 2.0/2.5 m;
Cruising speed is of 10.8 kn;
Autonomy is of 15 days.
RRR class notation is of: M-SP 3.5 (ice 40) A.
Two full-circle rudder propellers (RP) SRR 330 FP with capacity of 2x405 kWt are used as movement and manoeuvre facilities. Fixed pitch propellers are in nozzles with diameter of 1,20 m.
Energy to the RP unit is transferred through Z-gear from two MAN high-speed diesels with capacity of 405 kWt each.
Vessel's fore end has increased ice strengthening. Double sides along almost whole length from forepeak bulkhead to afterpeak bulkhead and double bottom from forepeak bulkhead to fore ER bulkhead are mounted for increasing parameters of vessel's survivability. Fuel and oil tanks have no points of contacts with outer hull plating.
Cargo hydraulic crane with lifting capacity of 8 tons and boom of 10,0 m is used for ensuring main vessels' functions, as follows: taking out, mounting and service of navigation floating buoys. Crane can be operated during sea roughness up to 3 without loss of lifting capacity with maximal boom reach.
Falling the anchors off from the deck during buoy mounting is carried out by 3 t raisers.
It is supposed to use workboat for floating navigation buoys' servicing.
Crew consists of 12 persons. Officers are arranged at single module cabins with individual water closets, other crew members are arranged at single and double cabins with washstands. Single cabins for supervisors/inspectors are foreseen.
Hydrographic GPS receiver, single beam double-frequency echo-sounder and portable sound velocity profiler are provided hydrographic functions of the vessel.
Special program complex for carrying out navigation buoys mounting and monitoring is provided.
Vessel's keel (building No. is of 902) was laid down on 15.03.12.
