Launch of the lead multi-functional buoy craft of BLV01 project

On April 28, 2011 the lead multi-functional buoy craft (BLV01 prj.) was launched at Shipyard "Nizhegorodskiy Teplokhod" (Sergey Konovalov is a director).
"Lotsmeister-1" is the vessel's name.
Customer is St. Petersburg branch of Federal State unitary enterprise (FSUE) "ROSMORPORT".
Project BLV01 was designed by the Marine Engineering Bureau (MEB).
Buoy craft is assigned for mounting of navigation buoys at port area and port approach ways, also maintenance and unmounting of these buoys.
Sailing region is area of sea port of St. Petersburg (including mouth parts of Neva river), and ports of Primorsk, Vyisotsk, Vyiborg, Ust'-Luga.
Vessel is of singe-deck double-screw type with forecastle, transom stern and stern crinoline, with fore operational deck that allows to place 4 buoys of BMBL-78 type with anchor gear simultaneously, with main engines and living deck-house located aft, with cargo crane that provides buoys' operation.
Vessel's principal dimensions are as follows:
Overall length is of 42.00 m;
Length between perpendiculars is of 37.90 m;
Overall breadth is about of 10.20 m;
Breadth of the summer load line level is of 9.20 m;
Depth is of 3.30 m;
Summer freeboard load line is of 2.5 m;
Full cruising speed is of 10 kn;
Autonomy is of 7 days.
Russian Maritime Register of shipping class notation is of KM  Ice 3 R2-RSN AUT3-C.
Two full-circle rudder propellers (FSRP) SPR 330 FP with capacity of 440 kWt each are used as movement and maneuverability gear. Diameter of fixed pitch propellers in nozzles is of 1.4 m. Energy to the FSRP unit is transferred through Z-gear from high-speed diesels with capacity of 442 kWt each.
Hull's theoretical forms were defined using calculating hydromechanics methods (CFD modeling).
Vessel's fore end has increased ice strengthening, forecastle can be easily transformed for ramp mounting that provides roll-on method of loading-discharging.
Cargo hydraulic crane with cargo lifting capacity of 8 tons with handling radius of 12.0 m provides main vessel's functions: mounting, unmounting and maintenance of navigation buoys. Crane can be operated during heaving of the sea up to 3 forces without loss of cargo lifting capacity with maximum handling radius.
Special capstan with towing tension about 5 tons is used for carrying out main functions: lifting buoys' anchors from the ground, raising chains of buoys' anchors in and putting them into cable locker specially equipped under main deck.
Hydraulic lifts are used for anchors' discharging from the main deck (anchors with weight up to 3 tons) during buoys' mounting.
Besides, cargo crane with capacity of 1 ton is located aft. It is used for working boat launching, foodstuffs and supply loading, for buoys' maintenance that are led to stern operational crinoline.
Working boat can be used for buoys' maintenance, for boom deployment during vessel's participation in oil spill response operations. Brush skimmer, motorized reels with booms (overall booms' length is of 500 m) and buoyancy tanks for gathering of oil-water mixture are also used for oil spill operations. Gathered mixture can be pumped into special vessel tank with capacity about 80 cub. m.
Hydrographic DGPS-receiver, hydrographic echosounder, sensing head for measuring of vertical sound speed in water and side-scanning sonar are used for hydrographical and survey vessel's works.
It is supposed to continue building of buoy craft of BLV01 prj. for other branches of FSUE after optimization of main designing decisions onto head vessel.
Keel of "Lotsmeister-1" vessel (building No 901) was laid down on 15.07.10. She was launched on 28.04.11.
