Solemn flag hoist on buoy craft of BLV01 project in water area of "Lenexpo"
On June 30, 2011 solemn flag hoist on the lead multi-functional buoy-craft "Lotsmeister-1" of BLV01 project was took place at International Maritime Defence Show (IMDS) in St.Petersburg.
On June 28, 2011 the vessel successfully passed sea trials, including heavy buoys of BMBL-78 type test mounting and lifting aboard, and unfolding of oil spill response equipment.
"Nizhegorodskiy Teplokhod" (Sergey Konovalov is a director) is vessels' builder.
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, Vysotsk, Vyborg, Ust-Luga.
Vessel is of singe-deck double-screw type with forecastle and transom stern, with middle operational deck that allows to place 4 buoys of BMBL-78 type with anchor gear simultaneously, with ER and living deck-house located aft, with cargo crane that provides buoys' operation.
Vessel's principal dimensions are as follows:
Overall length is of 43.09 m;
Length between perpendiculars is of 35.89 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 (FCRP) SPR 330 FP with capacity of 405 kWt each are used as movement and maneuverability gear. Diameter of fixed pitch propellers in nozzles is of 1.2 m.
Energy to the FCRP unit is transferred through Z-gear from high-speed diesels Volvo Penta D16MH with capacity of 405 kWt each.
Hull's theoretical forms were defined using calculating hydromechanics methods (CFD modeling).
Vessel's fore end has increased ice strengthening.
Cargo hydraulic crane with cargo lifting capacity of 8 tons with handling radius of 10.0 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.
Hydraulic lifts are used for anchors' discharging from the main deck (anchors with weight up to 3 tons) during buoys' mounting.
Working boat can be used for floating beacons' maintenance.
It is possible to transport boom deployment and equipment during vessel's participation in oil spill response operations.
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.
Special cargo tank with capacity about 53 cub. m. is located fore and assigned for acceptance of sewage water from vessels.
It is supposed to continue building of buoy crafts 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. She was put into operation on 30.06.11.
