(54) STORAGE DEVICE FOR FLOATING MEANS OF TOWED SEMIWEAR

FIELD OF THE INVENTION The invention relates to shipbuilding and relates to storage devices on a floating craft of towing semi-tail.

A device for storing on a floating craft a towing submragie is known, which contains outlets connected by the front ends with a triangular plate and connected to the body of the floating means (IJ.

The disadvantage of this device lies in the high labor intensity of working with a half-enemy.

The purpose of the invention is to reduce the labor intensity of working with a half-enemy.

The goal is achieved by the fact that the device is equipped with trays mounted along the sides of the craft, in which towing semi-foils are laid, each of which is equipped with a cable guide, and the front ends of the trays are made with guides.

In addition, the guiding devices can be made in the form of a gate, and the bends are provided with cartridges that interact with the gateways.

Moreover, the klyuz can be made detachable from two parts.

Trays can be equipped with butts, located inside the trays.

FIG. 1 shows a device for storing a towing halfprag, a general view (ujTpnx-nyHKTnpHUMH lines are shown

, towing half-prague in working position) -, in FIG. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; FIG. 4 shows a section B-B in FIG. one; in fig. 5 - the position of the rear end of the withdrawal of the semi-fob in the working position of the semi-fob.

The storage device for towing submragis on a floating craft consists of trays i installed along the sides of the floating craft 2, in this case the floating drilling rig, at the level of the upper deck. Tray 1 contains a flooring 3, made with holes 4, designed to drain water, bounded on one side by wall 5. At the front end of tray 1, a guide device in the form of a cast lock 6, which is detachable, is mounted.

On board the drilling rig 2, along the chutes 1, the butt 7 is uniformly mounted, for which the cartridges 8 are mounted, in which the rear ends of the taps 9 of the towing half-arm are embedded, and the cartridges 8 exceed the gaps of the gates 6 in their gab. 11, which are attached to the cable conductors 12, brought through canifas blocks 13, mounted on the rear wall 14 of the trays 1, to the winch mechanisms 15. The taps 9 are connected to the triangular link 16, to which the cable conductor 17 is also attached, fixed th on the top deck of the floating rig 2 via the cable 18 stonora.

The device for storing the towing submurge works as follows.

The towing vessel approaches the drilling rig 2. From the towing unit to the installation 2, a throwing end is fed with a lineette, to which an auxiliary small diameter steel cable is connected. On a floating drilling rig, choosing the throwing end, the steel cable, which is attached to the triangular link 16, is selected, respectively, then the cable guide 17 is released by removing the cable stop 18 from it.

The rear ends of the branches 9 of the towing half-forage using the cartridges 8 in the stowed position are fixed to the end of the butt 7.

Before the towing of the floating means 2 after the release of the triangular link 16, the taps 9 are given a slight tension, by selecting the ropes 12 by the winch mechanism 15, to relieve the load on the axis of the cartridges 8, after which the cartridges 8 are removed from the butt 7.

The towing semi-foil can be deployed in two ways: either by pulling the ropes 12 with the mechanism 15, and the towing semi-foils 9 under the force of the free triangular link 16 will crawl along the tray 1 and press the cartridges 8 into the blue of 6, or the towing vessel, putting the steel rope on the towing winch, there is no towing half-enemy.

After pulling the towing half-arm on the triangular link 16, the main towline of the towing vehicle is secured, while the cable guide 17, connected to the triangular link 16, is fixed on the deck of the floating equipment 2, having previously etched it overboard so that it will not tear. in the extreme working position of the towing semi-foil.

After performing the described operations, towing is performed.

The process of hauling a sub-forage into the floating means 2 is carried out as follows.

With the end of the towing on the vessel, the towline is disconnected from the triangular link 16 and the triangular link 16 is pushed with the taps 9 fixed on it into the water.

The winch mechanisms 15 choose the cable 12, and accordingly, the bends 9.

When the natrons 8 are against the end butts 7, they are fastened to the butt and the load from the ropes 12 is removed.

The rope guide 17 is put on the winch mechanism, then to the upper deck

the triangular link 16 is tightened, a cable stopper 18 is placed on the cable guide 17, and the triangular link 16 is fastened with straps.

Using the proposed device

for storing the towing demurrage on the floating device in comparison with the known ones, it allows to quickly and efficiently inspect the tugs of the towing half demurrage, while replacing the ropes is simplified.

Due to the fact that the rear ends of the bends

towing semi-foes are free and their fixation occurs in the ports without the use of manual labor, the deployment of the tow line in comparison with the known devices is much faster.

When tapping taps, the upper deck does not become cluttered, i.e., additional areas appear for more convenient placement of equipment. Execution of the split-lock key allows emergency return of the semragrag branches and facilitates their replacement during operation. The proposed device allows the length of the towing floor to be adjusted. Bragi, i.e., change the angle formed by the taps. This is achieved by the fact that directly in the process of towing

to be selected by the winch mechanisms and fixed by the rear ends on the intermediate butt heads in the chute, while practically the angle can be changed from 45 to 180 °, i.e. it is possible to move from one towing scheme with the help of a semi-tail to another towing scheme - towing on one rope ( towing schemes on one cable will occur with a fully retracted half-cage and securing of the outlets on the end heads.

The proposed device reduces the complexity and increases the convenience and safety when deploying and folding a towing semi-foil.

The device can be applied to other floating equipment, for example, floating cranes, using hollow felts made of tubular elements as trays.
