The invention relates to marine systems for receiving, loading and unloading buoy transmitting fluid materials, mainly hydrocarbons or materials in powder or granular form.

A device for directions submerged loading and unloading buoy into the receiving space at the bottom of a floating vessel with the retraction of the buoy in a fixed position in the receiving space, over which the vessel is a vertical shaft, or lowering of the buoy connected to a lifting cable for retracting buoy and in a fixed position connected with pipeline system in the vessel containing the guiding elements (US 4604961 A, 12.08.86).

The technical result from the use of the invention is about the Noah space.

The technical result is achieved in that the device for guiding submerged loading and unloading buoy into the receiving space at the bottom of the sailing of the ship when the pull buoy in a fixed position in the receiving space, over which the vessel is a vertical shaft, or lowering of the buoy connected to a lifting cable for retracting buoy and in a fixed position connected with pipeline system in the vessel containing the guiding elements, provided with a guiding cylinder, is arranged to move in the longitudinal direction of the shaft and coaxially with respect to it between the upper, retracted position and a lower, forward position. The device is equipped with drive means for moving the guide cylinder in a desired position and stabilizing elements for lateral stabilization of the guide cylinder, and the guide members are located on the lower end of the guide cylinder with the formation of guide holes for guiding contact with a lifting cable connected to the buoy.

Guiding elements can be located on the guide cylinder with the opportunity to interact with the n connected to the buoy.

Guiding elements can be made in the form of guide rollers, forming an almost continuous inner ring, or in the form of rotary elements, enabling rotation of the rotating outer element buoy for making this buoy when it is retracted one of a limited number of angular positions.

The guide cylinder can be located within the shaft and to rely on internal stabilizing elements or may be located outside of the mine and have lateral stabilization by external stabilizing elements. Thus the stabilizing elements may include longitudinally extending rails guides and rollers and/or stabilizing tabs.

The means for the mechanical movement may contain one or more hydraulic, pneumatic or electric actuators.

In addition, the device may contain restrictive means available to determine the lower position of the guide cylinder. When this data is restrictive means may include fully or partially surrounding the mounting flange or a separate bounding the tabs on the lower end of the shaft.

In Fig. 1 is this vessel adapted to receive a loading and unloading buoy and is equipped with a device according to this invention for the direction of buoy (the guide cylinder of the device shown in its lower end position);

in Fig.2 - same, but in this case, the guide cylinder is in its upper position of rest;

in Fig. 3 - cut the bottom of the ship during its movement in the stormy sea during retraction loading and unloading buoy (the position at which the guide elements of the guide cylinder in the form of videos pubescent so low to the buoy that a single rope lifting bridle is bent inside).

In Fig. 1 shows a section of the bow of a vessel 1 having a receiving space 3 in the bottom. The vessel is a tanker, for example the so-called Shuttle tanker and the receiving space 3 is adapted to receive a loading and unloading buoy to move, for example, oil or gas. In Fig. 1 buoy is not shown. In the initial position of the buoy anchored to the seabed and is so deeply that does not pose any danger to shipping. The first phase of the moving fluid, such as oil begins with the fact that the vessel 1 is moved in a position in which the receiving space 3 will be almost directly above the fixed loading and unloading buoy. In the fore part of the vessel shown assumes the presence of three adjacent screws, so-called nasal pushers, kotorii the correct position of the vessel. Suitable means, for example, with the help of submersible cable and/or auxiliary cables capture the hoisting rope of the buoy and I pull him up on deck 8 of the ship through the receiving space 3 and above it the shaft 9, providing access or service. Mine maintenance 9 can tightly closed shutters, of which the top flap 66 is shown in Fig. 1. On the upper end of the shaft 9 preferably will churn horizontal storage 67 for a spare cable with a possible indicator buoys.

The device 10 for the direction of the buoy in place when it is pulling, which can also be used for the direction of the buoy when it is release and lowering, as the main part has a guide cylinder 11. This cylinder is located coaxially with the closing of the mine maintenance 9 and can move in the longitudinal direction of the shaft from the upper, retracted position of rest (shown in Fig.2) through the guide section, where you can direct loading and unloading buoy, at the bottom, protruding or forward end position shown in Fig. 1. Moving guide cylinder by using one or more of the Executive mechanismof 12 attached to the top end to the hull, at that time, as the rods 14 of their pistons lower end connected with the lower portion of the guide cylinder 11. The limits of movement of the cylinder actuators and guide cylinder must be so large that the cylinder is in its forward end position provided good direction hoisting rope and lifting bridle buoy in the early stages of the retracting buoy, when the upper part of the buoy is introduced into the receiving space 3. At the same time the guide cylinder 11 must be capable of being drawn so high up, to the lower end of the shaft maintenance 9 and the bottom guide cylinder formed space available for staff. In this space there is also the connection of the buoy and pipeline system of the vessel. In Fig.1 and 2 show such a connection using the rotary connecting device 52.

As shown in Fig.1, the horizontal stabilization of the guide cylinder 11 through the upper stabilizing rollers 15 and the lower stabilizing protrusions 16. They may be distributed circumferentially around the lower enlarged portion 17 of the guide cylinder 11. Instead of a separate stabilizing protrusions may m a stabilizing flange or partly instead on the lower end of the guide cylinder can be installed stabilizing rollers. Thus, the purpose of the rollers, sections, flange, etc. is stabilizing, i.e., a horizontal support with the simultaneous assumption of vertical movement. In the shown embodiment of the invention the guide cylinder 11 is located inside the mine maintenance 9. An alternative solution guide cylinder may fully or partially surround the mine. In this case, the stabilizing elements will be located on the inner side of the guide cylinder and rely on the appropriate elements on the outer side of the mine. In the shown embodiment of the invention depicted a pair of guide rails 18 for directions stabilizing protrusions 16, with the upper stabilizing rollers 15 are shown in direct contact with the opposite walls of the mine maintenance.

The lower end position of the guiding cylinder is determined by the fact that the stabilizing protrusions 16 or stabilizing flange will rely on specific restrictive tabs 19 or the corresponding surrounding flange.

At the upper end of the mine maintenance 9 it is 67 for storing auxiliary hoisting ropes and forefinger buoys. To the capacity of the cable will normally be attached to the hoisting cable 30, in order buoy 2 was free to fall in case of emergency.

At the upper end of the guide cylinder 11 has a funnel-shaped extension 20 having a bottom 21 with a Central hole. This funnel shape can be practical for several reasons, one of which is to ensure the free passage of the hoisting ropes buoys through the guide cylinder from the storage space 67 at the upper end of shaft 9.

In Fig.3 schematically shows how to use the device 10 according to this invention, it is possible to carry out the direction of loading and unloading buoy 2. In the shown embodiment of the invention buoy 2 consists of the top 35 and bottom 36 of the conical parts. In addition, the buoy is equipped with a lifting bridle 39 having, for example, three mounting cable 40, which, as shown in Fig. 3, mounted with an angular interval of 120oon the periphery of the upper conical part 35 (Fig.3 rear left mounting cable 40 is closed the front by cable). Fixing the cables converge at the top and their upper ends attached together to a single hoisting cable 30. Due to the fact that the lifting bridle 39 has at least two retaining wire 40, is created in a certain sense attached to the reinforced portion 51 on the lower side of the lower conical part 36, and the bottom of the buoy is assumed transport pipeline 6. In the position shown buoy - vertical, at that time, as the vessel 1 is experiencing significant side or rolling keel, so the introduction of the buoy into the receiving space 3 is more or less inclined. In the position shown guiding device 10 according to this invention has its guide cylinder 11 located in the pilot area at some distance above the lower, forward end position, which is determined by the contact of the stabilizing protrusions or similar to that shown restrictive flange 31. The actual guiding elements guide device is made mainly in the form of guide rollers 41, which in the shown embodiment, the invention is made, as nearly continuous inner ring at the lower end of the extended portion 17 of the guide cylinder 11. Due to the fact that the guide rollers 41 are configured in the form of a ring, provided that the fastening ropes 40 always have a roller support regardless of the rotation of the buoy 2 or the outer rotating part relative to the longitudinal direction of the vessel. In another embodiment of the invention healthy lifestyles is and the other. In addition, you must then use a special mechanism to prevent jamming of the fixing ropes in the angles between the individual rollers.

When receiving bridle 39 is, as shown, three mounting cable arranged with an angular interval of 120oand when the outer part of the buoy 2 at the same time made rotatable relative to the mooring ropes 5 and the transport pipe 6, in the case of an inclined input or retraction of the lifting cable 30, slightly tilted relative to the longitudinal axis of the guide device 10, the lifting bridle will be rotated in one of three positions, with an angular interval of 120o. This can be useful in relation to the premises and the fixation of the buoy in the receiving space. In order to control the retraction of the buoy, and perhaps also when it descends on the inner side of the guide cylinder 11 can be mounted camera 32.
