The invention relates to shipbuilding and ship repair, in particular to floating docks.

The purpose of the invention is to improve working conditions and safety when docking multi-hull vessels.

FIG. 1 shows schematically a floating dock (PD) with the portions of the pontoon shifted, an end view; in fig. 2 - the same, with parts of the pontoon moved apart; in fig. 3 - the same, top view.

The device contains towers 1, which are rigidly connected by Parts 2 and 3 of the pontoon, containing sections of the berth-deck 4 and 5, respectively, on which dock support devices {DOW) 6 and 7 are installed. Vertical inner longitudinal walls 8 and 9 of parts 2 and 3 of the pontoon made in the form of cylindrical surfaces, between which a cylindrical insert 10 is installed, which is divided by vertical bulkheads 11 and 12, placed along the center plane of the dock, into equal semi-cylinders 13 and 14, respectively, which are interconnected in the lower part by means of hinges 15 and hinged by means of hinges 16 and 17 to parts 2 and 3 of the pontoon. The connecting elements connecting parts 2 and 3 of the pontoon are made in the form of, for example, hydraulic cylinders 18 with rods 19, which are fixed on the end walls 20 and 21 of parts 2 and 3 of the pontoon, respectively. Parts 2 and 3 of the pontoon can be provided with locks for fixing them in a shifted position, for example, mechanical locks (not shown). If necessary, additional shelters 22 can be installed on bulkheads 11 and 12, for example, when three-hulled vessels are being staged.

The proposed PD works as follows

When placed in the PD of a single-hull vessel (not shown), the rods 19 are retracted into the hydraulic cylinders 18 and parts 2 and 3 are shifted. In this case, the vertical bulkheads 11 and 12 of the semi-cylinders 13 and 14 are placed vertically (FIG. 1). When setting, for example, a catamaran ship (not shown), the rods 19 extend from the hydraulic cylinders 18 and pontoon parts 2 and 3 (FIG. 2) are moved apart, while the vertical bulkheads 11 and 12 of the semi-cylinders 13 and 14, which are connected by hinges 15 and attached with hinges 16 and 17 to parts m 2 and 3 of the pontoon, rotated 90 ° and placed perpendicular to the diametral plane of the AP. Thus, the sections of the berth deck 4 and 5 of parts 2 and 3 of the pontoon and vertical bulkheads 11 and 12 of the half-cylinders 13 and 14 of the insert 10 lie in the same horizontal plane

and form a single dock slipway. For staging a three-ship (not shown) on bulkheads 11 and 12, DOW 22 is installed (Fig. 3). Shifting parts 2 and 3 of the pontoon is performed, performing operations

in reverse order.

Claims (1)

Invention Formula A floating dock containing towers rigidly connected to parts of the pontoon that are connected by connecting elements, characterized in that, in order to improve working conditions and increase safety when docking multi-hull vessels, each part of the pontoon is made with a niche in which there is a compartment made in the shape of a semi-cylinder and pivotally attached by its upper edge to the slipway of this part of the pontoon, while the semi-cylindrical compartments of both parts of the pontoon are pivotally interconnected by the lower edges.
