The invention relates to the operation of a fleet, in particular to ship-raising facilities, for example, floating docks ,.

The closest to the invention to the technical essence and the achieved result is a floating dock containing a pontoon with ballast compartments, above which are towers and a slipway, mounted on the supporting devices Cl 2.

. The disadvantages of it are the low stability of the floating system. At the same time, during the ascent and the dive and the increased size and weight of the system.

The purpose of the invention is to increase the stability of the floating dock system during the ascent and the dive and to achieve the minimum dimensions and weight of the dock.

This goal is achieved by the fact that in a floating dock containing a pontoon with ballistic compartments, over which the towers are installed, and a slipway, on which support devices are mounted, open holes are mounted on the free surface of the slipway and on the ledges of the towers. to remove water from them.

FIG. 1 shows the proposed; floating dock with boxes and devices, top view; in fig. 2 floating dock with docked vessel and pipes, connecting boxes with dock ballast system, cross section in FIG. 3 - the same, with holes in the longitudinal and transverse walls of pshki for removing water from them by gravity onto the building deck of the dock; in fig. 4 is the same, with holes in the stocks-palu for removal (by-pass) of water from

ballasts in ballast compartments; in fig. 5 - floating dock with docked vessel, cross section.

The floating dock contains towers 1, ballast compartments 2, pontoon 3 and slipway - deck 4, on which it is installed. Lena support devices 5 for the docked vessel 6 and open from above boxes 7 for increasing the stability of the docking vessel system during ascent. Holes 8 are drilled by gravity in the latter to remove water during the ascent of the dock from the boxes 7. Water through the ballast system 9 is removed by means of pipes 10 connected to the boxes. To drain the water into the ballast compartments 2 in the Stock-4 stocks, a screwdriver was drilled; Boxes .7 can be installed on the ledge of 12 towers of 1 dock.

The ship is docked in the following manner.

The dock is submerged on a predetermined draft by accepting water ballast into the ballast compartment and the ship being docked. Due to pumping of ballast water from the bays of the bays, d & k podsplivaet up to the draft, which the vessel reliably sits on the dock's keel track. Due to pumping out the rest of the ballast from the ballast compartments, the dock with the dock is put into the working position1} e.

The reduction of the influence of the free position of the ballast wafer is achieved by grandfathering the free surface of the ballast water above the slipway in the longitudinal and transverse walls, formed in vertical 7, open at the top.

The application of the invention may reduce the mass of the dock and its cost in comparison with the docks of known construction.
