The system for transporting a fluid product, in this document, liquefied natural gas, between the two courts, as shown in Fig.1 and 2, includes a metal support structure mounted on the first vessel 10, such as floating production, storage and shipment of liquefied natural gas, and which supports at the end of the horizontal support arm 1 three units of three double-rotating connection, also known under the trademark "rotations" 12, described in more detail below. This design also supports the winch 13, in this case 3, for handling internal segment 2a of each of the three tubular device 2 for conveying a fluid product, the deflecting rollers 14 for each of the cables 15, is wound on the winch 13 and sets of pipes 16 connected to the pipeline network of the first vessel 10. It should be noted that shunting winch 13 is located at a distance in the design to reduce the load overhang and to provide access for maintenance and repair.
The support arm 1 is held in this case, essentially perpendicular to the vertical leg of the support structure that supports it.
Int is NNI segment 2a of each of the tubular structure 2 includes a rigid tube, usually with a diameter of 16” (1 inch = 254 cm), and reinforced in this document in its center through the use of a wider pipe (20” or 24”), or, alternatively, by choosing specific materials to ensure the rigidity of the system. Other types of hardening is also possible.
Each internal segment 2a is connected to node three rotating joints 12 on the same side as the supporting structure, and outer segment 2b of the tubular structure 2 by means of two bent tubes and one rotational coupling 17 and point 18 attachment for shunting cable 15 is the next to the last rotating connection.
The outer segment 2b of each of the tubular structure 2 formed in accordance with the same principle as the internal segment 2a. At the end of this segment 2b node 3 rotating units connected to the safety valve 5, the final node (see Fig.3). A relief valve is also connected with the centering cone 3, made with the possibility of alignment segments for final connection.
In Fig.1 also shows off the transportation system. This provision provides a rigid attachment of the outer segment 2b system that is required for optimum safety in the event of a storm, as well as during maintenance and repair. latform 20 for maintenance of the vessel 10 provides access to the very important elements to perform any repair work.
In practice this outside position, which, essentially, is the source (i.e. it is, in particular, can be considered independently of the first and second means defined above), outer segment 2b passes downwards from the support structure, in this case vertically, so as to be readily accessible from the deck of the vessel 10 and, more specifically, its platform 20 while the inner segment 2a passes along the support arm 1, that is, in this case horizontally, and thus at right angles to the outer segment 2b.
The second vessel, in this case the tanker for transportation of liquefied gas and connection of each of the hinged tubular structure 2 by means of a connecting means, in this case, the coupling 6 with valve with an external centering cone 7 and the receiving winch 33, mounted on the bow of the vessel (see Fig.3). This boot device provides a safe distance of approximately 60 m between the two vessels and provides connectivity and transport of flowable product in marine conditions, specific for each manufacturing site. In practice, the second vessel 9 is kept along the axis of the first vessel 10 by means of two tow ropes 26 located on respective opposite sides of the fore part of the vessel 9, and which are fixed in the rear part of the first aircraft is 10.
The connecting elements located at the end of the tubular structures 2, and connecting elements located on the second vessel 9 to download, shown in more detail in Fig.3.
More specifically, regarding the elements mounted on each outer segment 2b, node three rotating joints 30, allowing rolling, keel pitch and yaw movement of the vessel 9, and which is connected to the first vessel 10, the ends of the cork valve 5, is configured to isolate the transportation system at the end of the transport gas. Intermediate rotating connection of this node is equipped with a device that restricts the rotation angle up to +/-5º to prevent rollover valve Assembly/cone in certain maneuver. In addition, the axis of the valve 5 in this document is inclined at an angle of about 20 ° relative to the vertical, formed by the axis of the outer segment 2b, in order to lie on the natural movement axis, if the outer segment 2b at the final stage of the connection.
Centering cone 3 is equipped with a device 31 for blocking the received cable 11 extending from the second vessel 9, and the winch 4, providing the tensioning of the rope connected to accept the cable to draw the cable in the locked position.
It should be noted that the winch can is also be independent of the centering cone through, for example, installed on a fixed structure located in a neighborhood outside of the provisions for storage of the tubular structure 2, to provide the same function.
As for the elements that are installed on the bow of the second ship 9, connected in series, the node equipment is installed for each articulated tubular design 2.
This site contains oriented down the sleeve 6 with the valve, the axis of which is inclined at an angle of approximately 20 ° in order to accommodate the channel of the valve 5 for the connection. This coupling 6 is equipped with a known emergency release.
The outer cone 7 is fixed on the sleeve 6 or mounted on the parallel construction, which provides the combination of these two channels for alignment before the seal of the coupling. This cone 7, in this case, may be oriented to ensure its alignment with the received cable 11 to an intermediate stage of the connection, described below. Guide roller 8 for this cable and switching the Jack 32 is made as one unit.
Reception winch 33 with its cable 11 is installed along the axis of the centering cone 7. This winch is a type of permanent rotation. On the basis of the present invention the tension of the cable 11, essentially continuously supported by the weight of the tubular design for connection independently researched the dependence on movements of vessels.
In Fig.4 and 5 in more detail, given an image of one of the nodes 12 three double rotating joints 28, is arranged to provide movement of the support structure in three planes (transverse horizontal motion, longitudinal-horizontal motion, vertical motion).
Each of these rotating units is double, that is, one rotating connection 28a product, doubled due to purely mechanical rotating connection 28b.
The purpose of this configuration is the liberation of the rotational coupling of the product from mechanical stress system and providing access to seals, rotary joints product by removing only one of the cone of the tube (while preserving the integrity of the site).
Reference may also be made to the publication WO 0066484 mentioned above, in more detail, describing the construction of the nodes of the pair of rotating joints.
Fig.6 and 7 illustrate an example of a system for damping oscillations based on a hydraulic motor connected to the limiter utilization, providing damping.
Therefore, the number of rotating joints in the articulated tube structure 2 is six. Adding rotating connections can significantly reduce the load on a rotating soy is inania and pipes and to avoid hardening (moreover, as provided above, see also the description of Fig.1 and 2) inner and outer segments 2a and 2b. In the case of tubular structures 2, containing seven rotating joints, the mechanical system must be installed to reduce vibrations caused by the respective movements of the two ships.
With regard to its mechanical parts (Fig.6), this system contains a ring gear 41 on the movable part of the rotating connection 28 of the node 12 and the hydraulic motor with the leading toothed wheel 40 mounted on the mounting portion of the rotating connection. When piping network design moves further with the movements of one or both vessels, the ring gear 41 also moves (ring gear is mechanically connected to the network of pipelines) and causes the rotation of the hydraulic motor 40.
Hydroscheme shown in Fig.7.
More specifically, when the hydraulic motor 40 is driven into rotation of the ring gear 41, the oil passes through the stopper 43 of the thread that holds the oil, thus reducing the speed of rotation of the motor and thus the rotation speed of the ring gear, thus providing damping. Limiters 42 pressure prevents excessive pressure in the event of fluctuations that are too bol is large.
Other elements, such as hydraulic oil coolers can be added by an expert in the field of technology, especially depending on applications.
Fig.8 and 9 illustrate a variant of the implementation of the system containing a support structure 1b, which can rotate about an axis of rotation, mounted on the first vessel 10. This option allows you to adapt to relatively large displacements of the working area transportation system (in particular, in relation transversely of the longitudinal pitching) of the second vessel 9 in difficult sea conditions, such as conditions in which currents and winds can change and overlap with orientations.
To ensure rotation of the structure 1b, the axis 21 of rotation, mounted on the first vessel 10, is the center of rotation, and a set of rollers 22 located on the guide 23 of the rolling supports the weight of the structure 1b, while ensuring its rotation. Two hydraulic Jack 24 is controlled by this rotation to fit the provisions of the design to move the second vessel 9, thus allowing to increase the working area transportation system. The area, in particular, is directly determined by the type of mooring defined for this application.
Rotating connection 25, in which the fluid product is also installed on the connecting pipelines is E. They are located along the vertical axis, as shown in Fig.9.
Furthermore, since the supporting structure 1b is rotating, tubular structure 2 is held in the off position due to a link from its external segment 2b directly to the support structure 1b (see Fig.9).
In the embodiment depicted in Fig.1, 2, 8 and 9, the second vessel 9 is kept along the axis of the first vessel 10 by means of two tow ropes 26, located one on each side of the bow and fixed in the rear part of the first vessel 10. This configuration prevents any interaction between the transport system (tubular design 2) and supporting the tow ropes of the second vessel 9.
If you are using one tow line 26 located along the axis aft of the second vessel 9 may be used variant, shown in detail in Fig.10.
Two fixed parallel construction 1 support tube loading device, which in this case is dual to each design and which cannot communicate with the Central tow rope 26 in the case of drift of the second vessel 9 in the given range.
Hard link 27a also depicted in this embodiment, between the two end flaps 5, and in which only the center of the regulating cone 3 provides two swivel tubular structures 2, which are connected mechanically.
On rotating joints, which are intermediate between the inner and outer segments 2a and 2b, another articulated mechanical link 27b provides a consolidation of the only cable 15, which is connected with shunting winch 13.
The purpose of this configuration is to simplify joins in reducing the number of necessary devices (winches, centering cones).
To connect tubular device 2 can be performed in the following stages:
- working on the second vessel 9, throws a rope or steel cable lanyard) 50 connected to accept the cable 11, the worker in the first vessel 10 (see Fig.11), so that the latter could connect it with the winch 4;
- winch 4 and the selection winch 33 are driven (the unwinding of the winch 33) to enter the cable lug 51, the connecting cable 11 and the rope 50 and, thus, the cable 11 in the inner centering cone 3 in order to block this cable lug 51 by means of a blocking device 31 (see Fig.12);
- shunting winch 13 is driven unrolling in order to make the internal segment 2a to rotate relative to the support arm 1 through node 12 in order to lower its end, by which it is connected to the external segment 2b, from its position of storage on the same side as the support arm 1 (see Fig.13). In practice, the move, the normal path which is an arc of a circle, reported to this end that in the end of the operation exceeds 90º;
- actuation of the selection winch 33 to pull (and, thus, move forward) connecting the outer end of segment 2b, made with the possibility of connection with the connecting means located on the second vessel 9 for connection with the connecting means on the lower side (see also Fig.13), and coordination of winches, which is working, lets get mentioned movement, and the outer cone 7 is oriented to align with the received cable 11. During these movements of the outer segment 2b forcibly rotated relative to the inner segment 2a around their common swivel in the direction of the sealing of the closed space formed by these two segments. Its free end, in this case, also falls on the part of the trajectory with respect to its storage position;
at the end of the tubular connection device 2 (see Fig.14) external centering cone 7 is essentially locked in position connection, i.e. its axis essentially parallel to the axis of the coupling 6 with the valve, while ka the winch is still powered in accordance with the preceding stage;
- when connecting an end of the valve 5 with the coupling 6 with the valve can be transported fluid product (see Fig.15). In this position the connection of the inner and outer segments 2a and 2b form an angle other than zero, respectively, vertical and horizontal, and a slight tension is maintained in the cable 15 to prevent tangling or dive into the water last.
The end of travel switches can be mounted on a swivel in the inner and outer segments 2a and 2b (in position 60, see Fig.15) for limiting the angular displacement between these segments, in particular, when the actuation shunting and foster winches are not running synchronously.
The detach operation uses the same logic in reverse order.
As shown in Fig.16, for large transportation systems than the systems shown in the preceding drawings, point 18 of the mounting offset of the outer segment 2b to provide retraction of the Assembly of the tubular device 2 in the storage position (the attachment point on the inner segment 2a is replaced by emphasis).
In this position the inner and outer segments 2a and 2b each tubular device 2 (three in the case of this variant in this case is connected mechanically and share the centering cone) the image of the ut angle, more 90º.
Hard rod 55 is additionally provided as an extension cable in order to better control its trajectory during maneuvering system.
In addition, the second shunting winch 13' is provided to replace the winch 13 in case of damage.
The present invention, as it has just been described, in a more General sense, provides the following details and benefits:
a. The idea of the hinged links (tubular levers) connected with the vessel sequentially from the bottom, requires no balancing, no winches for constant tension to prevent shock during coupling, reducing, in particular, the consumption of electricity. To be precise, the weight system supports take the cable in continuous tension, regardless of any movement of the vessel. The separation between the two elements are connected, is provided prior to final connection. The bodyweight of the system to ensure maneuver exclusively compared with other solutions mentioned in the prior art.
b. Metal construction, mounted on the aft mining ship has a reduced size and are usually fixed. In exceptional cases it can be rotated to provide more working area in accordance with the selected type swartout is.
c. Swivel pipe (tubular device designed to transport fluid are independent to provide redundancy in case of damage. In the case of liquefied natural gas, the minimum number is two (liquid + gas) may be increased to 3 or 4 to provide higher throughput and decrease loading time. They can also be mechanically connected together to reduce the time maneuvering during operations connection/disconnection (to ensure duplication, you can quickly disconnect).
d. System installed to reduce vibrations and containing hydraulic motor, shifting oil to create a damping may be replaced by a hydraulic Jack, gas cross stay or any other system for creating damping. It should also be noted that the hinge tubes can be connected together to limit or even exclude the impact of such fluctuations.
e. Equipment intended for series connection of the vessel is reduced to the greatest extent (coupling with valve and winch) to reduce repairs and maintenance. No need of specific rotary connection, no complex mechanical system.
f. Thanks to its design, the system is in charge of the AET easy draining of the pipeline at the end of the boot by means of a flow under pressure remaining liquefied natural gas through the outlet, located at the lowest point of the pipeline, located near the rotating connection 17 between the inner and outer segments 2a and 2b.
g. This system provides very good performance on the basis of bandwidth, up to 5000 m3/h liquefied natural gas for each pipeline transporting liquid, and a very low loss of load due to the absence of roughness inside the rigid pipe. However, flexible hoses, such as cryogenic hoses can be used.
h. All installed hard pipe designed for a service life of at least 20 years or even 25 years and only require regular maintenance without replacing the entire pipeline.
i. Reception winch can be located on the tubular device, if desired, winches and cables in a more General sense can be replaced by equivalent mechanical means known to the person skilled in the technical field.
It is obvious that the present invention is not limited to the described and depicted variant implementation and covers any variant of implementation and/or combination of their various elements.
