    “HORIZONTAL CONNECTION DEVICE [001] The present invention relates to a horizontal connection device, for coupling and connection on the seabed of a first pipe, which has respective first and second pipe ends at the connection point, including a first connection part that supports or maintains the first end of the first pipe, whose first connection part and first pipe are designed for laying and implementation in advance on the seabed, and where the first connection part includes a guide structure located at a distance away from the pipe end, and a second submersible connection part that supports or maintains the second end of the second pipe, whose second connection part and second pipe are designed to be lowered from the surface towards the first connection part, and where the second connection part includes a guide device located at a distance away from the pipe end and a connector disposed between the connecting parts, for final connection between the pipe ends.
    [002] In the present context, "horizontal connection device" has the meaning that the connection parts are leveled in a substantially horizontal direction.
    [003] In subsea structures, for example, manifold structures and valves, which are implemented on the seabed, the piping is normally arranged in them, having one or more pipes that end in open pipe substitutes or inlets, forming a point of connection. Each connection point includes a stationary connection part. The term “stationary”, in the present context, means relative to the submarine structure. The connection point is later used for connection to an external pipe.
    [004] There are two principles for connection devices, both vertical and horizontal. For a device
    Petition 870190046467, of 05/17/2019, p. 8/34
    2/16 horizontal connection, the connection point projects horizontally out of the structure. In the North Sea, this solution almost has market control. In other locations, such as the Gulf of Mexico, the vertical solution is the most commonly used.
    [005] An example of a vertical connection device is shown in the Norwegian patent document, NO 2009 2880.
    [006] It should be mentioned that, in principle, there are three different ways (or currently, two) for external connections to a structure:
    - Direct connection between two structures.
    [007] In this case, a rigid pipe having a movable connection part at each end will normally be used. This is usually called a bridge tube. The bridge tube will be manufactured based on the measurement of the relative position of two connection points.
    - Connection between the end of a pipe (rigid pipe) and a structure.
    [008] Practically, it is almost impossible (at least, quite difficult) to connect a rigid pipe line directly to a structure previously installed on the seabed. Thus, an intermediate piece of pipe, often called a spool, is provided between the pipe line and the frame. In order to be able to connect the spool with the piping, add piping will be welded directly to a small structure, including a connection point. A spool, at first, is like the bridge tube described above.
    - Direct connection of a flexible or umbilical tubing to a structure.
    [009] In some cases, this is the connection chosen for the use of so-called flexible tubes, instead of rigid steel pipes. These pipes can be compared with a large garden hose. Thus, it is not necessary
    Petition 870190046467, of 05/17/2019, p. 9/34
    3/16 a spool or bridge tube between the pipe end and the frame. The tubing is so flexible that it can have a movable connector part at the very end of the tubing, connecting this directly to the stationary connector part in the structure. Therefore, it is not necessary to make precise measurements of the position at the connection point in the structure.
    [010] The latter principle is that the present invention is correlated.
    [011] In order to facilitate the underwater coupling of pipe ends, a completely new connection device has been developed. As before, it consists of a stationary part leaning on a base structure, such as a manifold structure, a movable part to be lowered from the surface and a clamp type connector that performs the final connection operation. The now proposed connection device takes into account new considerations that, previously, have not been satisfactorily addressed.
    [012] An objective of the present invention is to enable the recovery of an entire underwater structure to the surface, in a way that is extremely easy in this context. This means that all tubes and external pipes disposed on the seabed and extended towards the underwater structure must be disconnected, remaining disposed on the seabed when the underwater structure is elevated.
    [013] Another objective of the present invention is to design the connection parts with means that allow them to be relatively aligned, in order to bring the ends of pipes in line, before the connection itself is made, at the same time, preventing the mobile connection part that has a fixed flexible tube from being allowed to tilt or withdraw.
    Petition 870190046467, of 05/17/2019, p. 10/34
    4/16 [014] Another objective of the present invention is to provide such a solution, so that the minimum amount of equipment possible remains on the seabed. With this new solution, guide structures and tools can be recovered to the surface after the connection device is installed. In this way, this provides savings with respect to the steel that is left on the seabed and, of course, the reuse of these tools and components, which, in turn, provide valuable savings.
    [015] Yet, another objective of the present invention is to obtain a minimum of subsea operations and ROV (Remote Operated Submarine Vehicle) interventions. The ROV disconnects the installation tools with two ROV locks. In this way, the installation vessel can leave the site and continue with the next installation. A different, smaller and more reasonable vessel can then continue with the ROV operations necessary to operate the traction / propulsion tool, in order to bring the ends of pipes in a way between themselves, before the final connection is made with the connector.
    [016] The objectives described above are achieved by means of a connection device of the said type of the present introduction, which, according to the present invention, is differentiated in that the guide device engages with the guide structure during a lowering movement of the second part connection point, and articulate the second connection part in rough alignment of the second end of the pipe, in the direction of the first end of the pipe, so that the first and second pipes are brought into alignment with each other on the seabed, and that the first connecting part includes an adjacent ramp structure having support surfaces and a guide device, designed to engage with cooperating surfaces and means in the second part
    Petition 870190046467, of 05/17/2019, p. 11/34
    5/16 connection, when the second connection part is moved towards the first connection part, for a fine alignment of the pipe ends.
    [017] In a preferred embodiment, the adjacent ramp structure can be physically separated from the first connection part. Then, the second connection part can be arranged in the ramp structure, subsequent to a disconnection operation, which is carried out between the connection parts. The structure of which the first connecting part forms a part can be recovered to the surface when required, while the other connecting parts remain disposed on the seabed.
    [018] In a practical embodiment, the ramp structure guiding device may include a projecting plate part, and the cooperating device of the second connecting part may consist of an incision or a notch. The projecting plate part and the notch connect with each other when the pipe ends approach and then prevent a possible tilting movement of the second connection part. In addition, it may have plugs or stops that prevent movement in the longitudinal direction.
    [019] Suitably, the support surfaces of the ramp structure include ramp-type surfaces, against which the cooperating surfaces of the second connection part act, thus providing a fine alignment between the pipe ends, when the second connection part is forward towards the first connection part.
    [020] In one embodiment, the guide structure can be a projecting and ascending carcass structure, capable of receiving the corresponding guide device disposed in the second connection part.
    [021] The guide device of the second connection part may include a projecting loop structure, which in an initial phase, in a sliding way, cooperates with the structure
    Petition 870190046467, of 05/17/2019, p. 12/34
    6/16 upward projecting housing of the first connection part. When the loop structure is fully inserted, it rests against a portion of the ascending projecting structure of the second connection part and articulates until it rests on the ramp structure, whereby said pipe ends are then roughly aligned each other.
    [022] In a practical embodiment, the first connection part may include at least one guide pin and the second connection part may correspondingly include at least one cooperating female part, which together constitutes an additional guide device.
    [023] The connector can form an integrated part of the connection device, in which the connector, in a variant, is attached to the second connection part. The second connection part is displaceable towards and away from the first connection part, in order to position the pipe ends, before the final connection of the pipe ends by said connector.
    [024] Alternatively, the connector can be attached to the first connection part and the second connection part can be displaced towards and away from the first connection part, again, in order to position the pipe ends, before connection end of the pipe ends by the connector.
    [025] In one embodiment, the connector can constitute a separate unit, which can be seated between the pipe ends, after which the pipe ends are roughly positioned and aligned relative to each other.
    [026] Normally, the connector will be of the “clamp connector” type, having annular and inclined surfaces arranged internally, which upon activation force two pipe flanges axially towards each other, where one
    Petition 870190046467, of 05/17/2019, p. 13/34
    7/16 of the flanges has a sealing ring disposed in it, having annular and inclined surfaces externally disposed. Alternatively, the connector can be of the “collection connector” type.
    [027] In the form of an accessory, it will be possible to introduce such equipment, so at least one of the connecting parts includes guidance means, capable of rotating the other connecting part in the horizontal plane, in order to roughly align the second connecting part with respect to the first connection part, so that the pipe ends are thereby brought up to be substantially aligned with each other, before further lowering the second connection part along said guide device.
    [028] As an alternative, the projecting handle structure of the second connection part can be in the form of a tool, arranged in a release way, and which can be recovered to the surface after the connection is made.
    [029] In order to pull or drive the connecting parts towards or away from each other, a pulling or pushing tool is used, the tool being operated by a Remote Operated Submarine Vehicle (ROV). To hold the tool, the first and second connection parts can have at least one support, adapted for insertion of the pulling or pushing tool.
    [030] Other and additional objectives, characteristics and advantages will arise from the following description of preferred embodiments of the invention, which are presented for descriptive purposes and provided in context with respect to the accompanying drawings, in which:
    figure 1 shows in a perspective view, taken obliquely from above, a horizontal connection device having the individual connection parts arranged separately;
    Petition 870190046467, of 05/17/2019, p. 14/34
    8/16
    figure 2 shows in a perspective view, the horizontal connection device according to figure 1, on the opposite side, and with the individual connection parts arranged separately;
    figure 3 shows a vertical projection view of the horizontal connection device, according to figures 1 and 2, with the individual connection parts arranged separately;
    figure 4 shows in a perspective view, taken obliquely from above, the mobile connection part isolated from the other connection parts;
    - figure 5 shows a perspective view of the
    part of mobile connection, in according to figure 4, of side opposite; and - the figures 6A -6H show strings in an operation of connection. [031 ]Firstly, is reference is made to the figure 1, what
    shows a complete connection device (10), which is developed to perform coupling and connection of pipes on the seabed. Said device is assembled by a first connection part (1), a second connection part (2) and a ramp structure (6).
    [032] The first connection part (1) is attached to an underwater structure (not shown), such as a manifold structure or a Christmas tree structure. The first connection part (1) can be considered as fixed in relation to the subsea structure. The first connection part (1) is so arranged that it supports or maintains the end (E1) of a first pipe, which will then be located inside the subsea structure. It should be understood that the first connection part (1) and the first pipe will be initially seated on the seabed (together with the underwater structure). The first connection part
    Petition 870190046467, of 05/17/2019, p. 15/34
    9/16 includes a guide structure (4), located some distance from the end of the pipe (E1).
    [033] Subsequently, the second connection part (2) must be lowered from the surface towards the seabed structure, more precisely, towards the first connection part (1). In view of this, the second connection part (2) can be considered as mobile in relation to the subsea structure. The second connection part (2) is so arranged that it retains the end (E2) of a second pipe. The second connection part (2) includes a guide device (5) located with some distance from the end of the pipe (E2).
    [034] The ramp structure (6) is located close to or adjacent to the first connection part (1). The ramp structure (6) has a main function when the connecting parts (1, 2) are leveled and, possibly, on later occasions if disconnection is made. The ramp structure (6) is provided with support surfaces and a guide device, which are designed to engage with cooperating surfaces and means in the second connection part (2), when the second connection part (2) is advanced towards the first connection part (1). When this is done, a fine alignment is achieved between the pipe ends (E1, E2).
    [035] A connector (3) is disposed in one of the connection parts (1, 2), shown here disposed in the second connection part (2). After the pipe ends (E1, E2) have been finely aligned with each other, and pulled together to a flange-to-flange contact, possibly with a seal between them, the connector (3) is activated and provides a long lasting connection between the pipe ends (E1, E2). The connector (3) is operated by a remote-operated underwater vehicle (ROV), which turns a threaded screw (3a) on the connector (3).
    Petition 870190046467, of 05/17/2019, p. 16/34
    10/16 [036] The connector (3) will normally be of the type of clamp connector, having sloping annular surfaces arranged internally, which upon activation force two pipe flanges axially towards each other. One of the pipe flanges has a sealing ring installed on it, having annular and inclined surfaces arranged externally. Alternatively, the connector can be of the “collection connector” type.
    [037] It should be emphasized that the ramp structure (6), in a preferred embodiment, is physically separated from the first connection part (1). Thus, the second connection part (2), when desired, can be arranged in the ramp structure (6) after a disconnection operation between the connection parts (1, 2) has been made. Then, the underwater structure, of which the first connection part (1) is part, can be recovered to the surface. Usually, many of these first and second connection parts (1, 2) are arranged for each subsea structure, and as is understandable, all second connection parts (2) will remain arranged in the ramp structure (6), in the bottom of the sea, when the subsea structures need to be recovered to the surface, for maintenance operations, modifications, repairs, etc. However, the described physical separation is not necessarily fully defined.
    [038] Reference is now made particularly to figure 3, for a description of more details of the ramp structure (6) and of the first and second connecting parts (1, 2), although the details are also shown in figures 1 and
    2. More precisely, the ramp structure guiding device (6) is designed and shown as a projecting plate part (6a) in the area adjacent to the first connection part (1), as shown in the figures. To be even more precise, the cooperating means of the second connecting part (2) are designed and shown as an incision (2a) or a
    Petition 870190046467, of 05/17/2019, p. 17/34
    11/16 notch. Furthermore, it should be understood that the projecting plate part (6a) in the ramp structure (6) becomes slidable with the incision (2a) when the pipe ends (E1, E2) are moved in the direction between them, in the terminal phase of the coupling operation. When the pipe ends are in complete coupling arrangement, they prevent any tilting movement of the second connection part (2) in relation to the first connection part (1).
    [039] The support or contact surfaces of the ramp structure (6) can, in turn, include ramp surfaces as suggested by the numerical reference (6b).
    Correspondingly, the second connecting part (2) has contact surfaces (2b) that cooperate with the ramp surfaces (6b) when the second connecting part (2) is moved in the direction of the first connecting part (1). When the notches (2a) are arranged to engage with the plate parts (6a), at the same time that the contact surfaces (2b) are raised by the ramp surfaces (6b) while advancing the second connection part (2 ) towards the first connection part (1), this movement provides a fine alignment between the pipe ends (E1) and (E2).
    [040] Furthermore, it should be noted that at the very rear end of the ramp structure (6), inclined surfaces (6c) are arranged projecting upwards, whose surfaces end on a straight edge (6d), below the ramp structure ( 6). This inclined surface (6c) works to direct the second connection part (2), through the contact surfaces (2b), below a base surface (6e), on the upper side of the ramp structure. When the contact surfaces (2b) actually approached and contacted the base surfaces (6e), the second connection part (2) is prevented from moving
    Petition 870190046467, of 05/17/2019, p. 18/34
    12/16 unidirectional to the rear, due to the straight stop edge (6d). Also, it should be noted that at the front end of the base surface (6e), a smaller edge (6f) is arranged. This edge (6f) has the important function of being able to prevent the connection part (2) from sliding in an uncontrolled direction towards the connection part (1), that is, without any active coupling by means of a traction or drive (not shown), usually in the form of a linear motor of suitable type and known per se. Through the stopping edges (6d) and (6f), the second connection part (2) is conveniently arranged on the base surfaces (6e), due to its own weight.
    [041] Additional details of the first connection part (1) consist of a back plate (7) and a front plate (8). The front plate (8) supports the first pipe end (E1). A plurality of clamps are arranged between the back plate (7) and the front plate (8), in a manner known per se. The front plate (8) has at least one adapted support (8a), in the form of a recess in the shape of (U), which is designed for insertion of the pulling or pushing tool. In addition, the faceplate (8) includes at least one guide pin (8b), shown here in number two, which are located on the bottom portion of the faceplate (8) and point towards the second connection part (2) .
    [042] Other details of the second connection part (2) consist of a main plate (9), which supports the second pipe end (E2). A plurality of tubular clamps are located perpendicular to the main plate (9) and the lower hollow clamps (9b) are simultaneously a guide device, in the form of a female part that must cooperate with the guide pin (8b) described above, during the finishing part of the coupling operation of the connecting parts (1, 2). The main board
    Petition 870190046467, of 05/17/2019, p. 19/34
    13/16 (9) has at least one adapted base (9a) in the form of a recess or notch in the shape of (U), which is designed for insertion of the pulling or pushing tool described above.
    [043] In addition, a first connection plate (9c) is rigidly connected between the hollow clamps (9b), at that end facing the first connection part (1), and a second connection plate (9d) it is rigidly connected between the hollow clamps (9b), at that end that faces away from the first connection part (1). The first connection plate (9c) includes the previously described incisions or notches (2a), which cooperate with the plate edges (6a) in the ramp structure (6), that is, more precisely, those plate parts (6a) that are facing internally the ramp structure (6). The second connection plate (9d) includes the contact surfaces (2b) described above, which, in sequence, first cooperate with the inclined surfaces (6c), then with the base surface (6e) and the top edges ( 6d) and (6f) of the ramp structure (6), before the contact surfaces (2b) start to move on the ramp surfaces (6b), during the last phase of the coupling operation.
    [044] Described in more detail, the guide structure (4) consists of an ascending projecting carcass structure (4a) divided into two parts arranged as a “Y relative to each other, and which are capable of receiving a corresponding guide device (5 ), disposed in the second connection part (2), and in the form of a removable tool. The guide device (5) of the second connection part (2) consists of a projecting loop structure (5a), which in an initial phase, in a sliding way cooperates with the upward projecting carcass structure (4a) of the first connection part (1). When the loop structure (5a) is fully inserted and rests against a part (4d)
    Petition 870190046467, of 05/17/2019, p. 20/34
    14/16 of the ascending projecting carcass structure (4a), the second connection part (2) is forced to articulate until it rests against the ramp structure (6). During this phase, the pipe ends (E1, E2) are roughly aligned relative to each other. The projecting loop structure (5a) of the second connection part (2) can preferably be in the form of a tool which is available in a release form and which can be recovered to the surface after the connection has been made.
    [045] Three options regarding the location of the connector (3) are contemplated. The connector (3) can be, as shown here, an integrated part of the connection device (10). In an alternative, the connector (3) can be attached to the second connection part (2), as shown in the drawings.
    [046] As an alternative, it is possible to imagine that the connector (3) is attached to the first connection part (1), in which the second connection part (2), as before, can be displaced towards and away from the first connecting part (1).
    [047] In a third alternative, it is possible to imagine that the connector (3) constitutes a separate unit, which can be seated between the ends of pipes (E1, E2), after which the ends of pipes (E1, E2) are roughly positioned and aligned relative to each other.
    [048] Also, it will be desirable to introduce that at least one of the connecting parts includes guidance means, which are capable of rotating the second connecting part (2) in the horizontal plane, so that the second connecting part (2) is allowed to roughly align with respect to the first connection part (1), so that the pipe ends (E1, E2) are brought in substantially in line, before the final lowering of the second connection part (2) against the first connection part (1).
    Petition 870190046467, of 05/17/2019, p. 21/34
    15/16 [049] Figures 4 and 5 show other perspective views of the second connection part, so that the entire object is shown.
    [050] Figures 6A-6H show sequences of the coupling operation that takes place between the connecting parts (1, 2) and through the use of a ramp structure (6), as an auxiliary device. Figure 6A shows how the second connection part (2) is lowered from the surface, for example, of a vessel from the surface. The second connection part (2) is designed to be arranged on the ramp structure (6), as described above.
    [051] Figure 6B shows the moment when the second connection part (2) collides with the first connection part (1), when the loop structure (5a) collides with the nozzle that faces upwards from the carcass structure configured in “Y (4a).
    [052] Figure 6C shows the moment when the loop structure (5a) rests on the carcass structure (4a), and begins to articulate in the direction of the ramp structure (6), around an articulation point which is exactly located at the base of the carcass structure (4a).
    [053] Figure 6D shows the moment when the second connection part (2) is settling on the ramp structure (6) and is guided through the inclined surfaces (6c). This is also the situation when the incisions (2a) are guided in and over the plate parts (6a), in order to make coupling with each other.
    [054] Figure 6E shows the first intermediate position, before the final connection is made. The contact surfaces (2b) are now supported against the base surfaces (6e) and are prevented by the stopping edge (6d) of backward movement. The notches (2a) are advanced for coupling with the plate parts (6a) and prevent tilting movement, as previously described.
    Petition 870190046467, of 05/17/2019, p. 22/34
    16/16 [055] Figure 6F shows the same situation as shown in figure 6E for the connection device (10), but in this case, the installation tool (110 is removed and recovered to the surface, for later use When the tool is removed, the edge (6f) prevents forward movement.
    [056] Figure 6G shows the situation where the second connection part (2) was pulled towards the first connection part (1) by means of a pulling or pushing tool (not shown). The contact surfaces (2b) begin to rise over the ramp surfaces (6b) and tilt the second end of the pipe (E2) in an upward direction.
    [057] Figure 6H shows the situation in which the second connection part (2) is completely coupled with the first connection part (1) and is ready to activate the clamp connector (3) for final connection. The notches (2a) have passed beyond the plate parts (6a) and now remain free and are uncoupled. After the final connection has been made, the contact surfaces (2b) are also raised from the ramp surfaces (6b). Thus, the entire second connection part (2) is free from the ramp structure (6).
    [058] It should still be understood that the solution described above is satisfactory in both flexible tubing and umbilical tubing. The entire connection operation works in the same way, but with more tubes at the end of the pipe (E2), in addition to a connection box (terminal) behind the end (E2), featuring electrical or optical connectors.
