Description

The invention relates to shipbuilding, and in particular to marine technical means for the development of the Arctic shelf, and in particular to systems for transporting fluid to a floating vessel from an underwater terminal in the Arctic shelf to a vessel located both in clear water and in drifting ice or in solid ice fields.

Designed to equip special vessels (tankers), including the ice class, with equipment for transporting fluid from an underwater terminal, located in particular on the Arctic shelf, and can also be used in the design and construction of ships for transporting fluid cargo.

The well-known "System for transporting fluid to or from a floating vessel" (patent RU 2125949, IPC B63B 22/02, publ. 02/10/1999), containing a buoy located on the vessel open down the receiving cavity for receiving and connecting to the buoy and a lifting means with a cable mounted on the deck of the vessel for lifting the buoy into the receiving cavity by the cable being lowered through the receiving cavity. The buoy is connected to at least one transmission pipeline for transporting a fluid and is mounted at anchor at the bottom of the sea with the possibility of being kept submerged at a given depth when not in use. The buoy is also made with a central element anchored at the bottom of the sea, intended for the passage of fluid from the transmission pipeline through the connecting device to the piping system on the vessel, as well as with an external floating element mounted for rotation on the central element to ensure rotation of the vessel around the central item.

The receiving cavity is made with the means of fastening the buoy in it and disconnecting the buoy from this cavity, the cavity is made of conical shape, converging in the upward direction, for at least partial coupling with the buoy made of the corresponding shape. The receiving cavity is completely located in the submerged part of the bow of the vessel and is connected to the deck of the vessel with a service shaft configured to allow passage of the said lifting means cable through it. In this case, the receiving cavity is made with a sealing flange located with the possibility of interaction with the mating abutment surface of the outer floating element of the buoy to seal the service shaft from the surrounding sea while fixing the buoy in the receiving cavity.

The disadvantage of the system is the technical complexity of the connection of the transmitting pipeline with the receiving cavity of the vessel.

The well-known "System for transporting fluid to a floating vessel (patent RU 2538739, IPC B63B 27/34, B63B 22/02, B63B 21/50, publ. 10.01.2015), adopted as a prototype containing a buoy connected to a flexible transmission pipe for transporting fluid from underwater equipment and mounted at anchor at the bottom of the sea with the ability to be kept submerged at a predetermined depth when not in use, a receiving cavity located in the submerged part of the vessel and a lifting means with a cable, a receiving cavity configured to pass and through it, a buoy, a transmission pipeline and a mooring line, is placed from the bottom to the top of the vessel with at least one of its walls inclined and provided in its upper part with a room for equipment connected to it, located in the hull of the vessel between its submerged part and the deck or on the deck and in which the lifting device and the docking and mooring devices are placed, made with the possibility of connection, respectively, with a flexible transmission pipe and mooring lines through the receiving cavity. The lifting device is equipped with a gripping device that is capable of gripping and raising the buoy and buoyrp and includes a carrier device and a gripping element, while the gripping buoy is made in the form of a robust sealed enclosure having positive buoyancy, with hydroacoustic and light beacons housed in it and connected by buirp with the head of the flex, which is connected to the underwater equipment mooring. The underwater equipment is made in the form of an underwater terminal with a bottom module, on which hydroacoustic and light beacons are installed, and the discharge valve and pump of the underwater terminal are made with the possibility of turning them on and off by a hydroacoustic signal.

The carrier device can be made in the form of a remote-controlled underwater vehicle equipped with a propulsion and steering complex and television-optical equipment. The gripping device can be made in the form of a frame structure with a detachable attachment unit to the cable of the lifting device and a buirp catcher.

The receiving cavity can be installed obliquely with a shift of its lower end relative to the upper end to the bow of the vessel.

The disadvantage is the presence of an open downward receiving cavity located from the lower to the upper part of the vessel, which complicates the system for transporting fluid to a floating vessel in terms of docking a flexible transmission pipeline with the corresponding vessel system and requires substantial refinement of the vessel design.

The objective of the invention is to simplify the system for transporting fluid to a floating vessel, eliminating its significant development, for example, the placement in the hull of an open downward receiving cavity located from the lower to the upper part of the vessel for receiving a flexible pipe, including in its submerged part.

The task is achieved in that a system for transporting fluid to a floating vessel, containing underwater equipment, an immersed buoy, connected to a flexible transmission pipe for transporting fluid from underwater equipment and installed on the bottom of the sea with the ability to keep immersed at a given depth when not in use. On the deck of the vessel are lifting and docking devices made with the possibility of connection with a flexible transmission pipe. The lifting device includes a carrier device equipped with a propulsion and steering complex and television-optical equipment. The underwater equipment is designed as an underwater terminal, on which sonar and light beacons are installed.

At the end of the flexible transmission pipeline, a ring is fixed, which serves to lift the flexible transmission pipeline to a floating vessel. The ring is equipped with sonar and light beacons. The submerged buoy is equipped with a winch with a control system that serves to fix the winch unlocking by a hydroacoustic signal and return the flexible transmission pipeline to the submerged buoy.

The invention is illustrated by drawings, where:

in FIG. 1 is a general view of a system for transporting a fluid to a floating vessel;

in FIG. 2 - an immersed buoy with a fixed flexible transmission line at the time of passage of the carrier through the ring;

in FIG. 3 - submerged buoy with a flexible flexible transmission pipe;

in FIG. 4 is a system for transporting a fluid after docking a flexible transmission pipe with a docking device of the vessel.

On the upper deck of vessel 1 are a lifting device 2 with a ship winch 3, a control system 4 of a carrier device 6 equipped with a propulsion and steering complex and television-optical equipment (not shown in the drawing), a docking device 5. A flexible transmission pipe 8 for transporting fluid environment from the underwater terminal 11 with a ring 7 fixed at its end, used for docking with a cable 12 connected to the ship’s winch 3, in the initial state it is fixed by the winch 9 with a control system (not shown in the drawing cauldron), which serves for fixing and unlocking the winch 9 according to the hydroacoustic signal located on a submerged buoy 10 mounted on the bottom of the sea, and the valve and pump (not shown in the drawing) are located on the underwater terminal 11, which also has hydroacoustic and light beacons 13 Ring 7 is equipped with sonar and light beacons 14.

The system operates as follows.

Vessel 1 approaches the submarine terminal 11 using the standard navigation system. An on-board recognition command is issued from the board to activate the sonar and light beacons 13 on the underwater terminal 11 and the sonar and light beacons 14 on the ring 7. At the same time, automatic preparation of the equipment for pumping fluid begins.

With the help of a lifting device 2 and a ship’s winch 3, the carrier device 6 is launched into the water from the vessel 1. The carrier device 6 using the control system 4, as well as by signals from sonar and light beacons 13 and 14 on the ring 7 and on the underwater terminal 11 passes through ring 7 and pops up. After lifting the carrier vehicle 6 on board the vessel 1 using a lifting device 2 and a ship’s winch 3, a cable 12 is pulled through the ring 7, the second end of which is also secured to the ship’s winch 3. An acoustic signal is sent to the winch 9 located on the submerged buoy 10 its release. Using a lifting device 2 and a ship’s winch 3, a flexible transmission line 8 is lifted aboard the vessel 1 and connected to the docking device 5. After conducting verification work, an acoustic signal is sent to the loading valve and pump (not shown in the drawing) located on the underwater terminal 11 to start transporting the fluid.

After the transportation of the fluid by the sonar signal, the loading pump and valve are turned off (not shown in the drawing). A flexible transmission pipe 8 is disconnected from the docking device 5 and lowered by a lifting device 2 and a ship winch 3 into the water. Disconnect one end of the cable 12 from the ship’s winch 3 and pull it out of the ring 7. Then, from the side of the vessel 1 a hydroacoustic signal arrives at the winch 9, which pulls the flexible transmission pipe 8 to the submerged buoy 10. After immersing the flexible transmission pipe 8 to a predetermined depth of the winch 9, located on the submerged buoy 10, is automatically turned off and locked. Hydroacoustic and light beacons 13 and 14, both on the ring 7 and on the underwater terminal 11, as well as the equipment of the terminal 11 go into "standby" mode.

The technical result consists in simplifying the system for transporting fluid to a floating vessel, eliminating the need for its substantial development.
