A plurality of tube couplers, such as couplers 102f, 102g, 102h, 102i, and 102j, are coupled to and extend from a surface 102k on plate 102. The couplers 102f-j include respective system connectors 102l, 102m, 102n, 102o, and 102p on their surfaces. A pair of guide flanges 102q and 102r extend from opposite sides of plate 102 and define guide holes 102s and 102t, respectively. A surface 102u is situated opposite surface 102k on plate 102.

The plurality of connection bars 104a-e extend from the surface 102u and have a second end, such as end 104g on connection bar 104e, which is circumferentially spaced apart from adjacent connection bars 104 and coupled to a collar 106 on a collar end face 106a. One or more of the connection bars 104a-e may receive one or more tubular buoyancy device, such as buoyancy device 104h on bar 104a.

The collar 106 defines a passageway 106b running longitudinally through the collar 106, and includes a rotational coupling inner wall 106c situated adjacent the passageway 106b and along the length of collar 106. A handle 106d is coupled to and extends radially from an upper portion of the collar 106.

An adapter 108 may be coupled to the collar 106 through the coupling of a rotational coupling outer wall 108a on adapter 108 with the rotational coupling inner wall 106c on collar 106. Coupling the adapter 108 to the collar 106 allows for relative rotation between the adapter 108 and the collar 106.

Each bend limiter 112 includes a plurality of bend limiter portions 112a and 112b which couple together to define a longitudinal passageway 112c that receives overhose 110. Each bend limiter portion 112a and 112b includes an internal annular groove 112d at one end and an external flange 112e at the other end. A plurality of bend limiters such as bend limiters 112f and 112g may couple to each other by situating the external flange 112fe on bend limiter 112f in the internal annular groove 112gd of bend limiter 112g.

In an exemplary embodiment, the bend limiters 112 are provided substantially as described in U.S. Utility patent application Ser. No. 10/841593, attorney docket #30383.6, filed on May 7, 2004, the disclosure which is incorporated herein by reference.

In an exemplary embodiment, the plate 102, bars 104, and collar 106 provide a connection member 116 for protecting the plurality of tubes 114, rotating relative to the overhose 110, and connecting the system to a connector. Connection member 116 includes a longitudinal axis 116a. In an exemplary embodiment, the adapter 108, overhose 110, and bend limiters 112 provide a tubular lead member 118 for protecting the plurality of tubes 114 and rotating relative to the connection member 116.

In an exemplary embodiment, during operation of the system 100, as illustrated in FIGS. 1, 2a, 2b, 3, 4, 5a, 5b, 6, and 7, a method 200 for termination is implemented using the system 100 in which, in step 202, the plurality of tubes 114 are extended through the tubular lead member 118 by way of the passageway 110a defined by tubular overhose 110. Once the tubes 114 are extended through the passageway 110a, at step 204, the tubes 114 are then extended through the passageway 108a defined by adapter 108, passageway 106b defined by collar 106, and through the holes 102a-e on plate 102 where they are coupled to the couplers 102f-j on connection member 116. With the tubes 114 coupled to the couplers 102j, at step 206, the collar 106 on connection member 116 is rotatably coupled to the adapter 108 on tubular lead member 118. With the collar 106 rotatably coupled to the adapter 108, the connection member 116 may rotate about the longitudinal axis 116a. With the tubes 114 coupled to the couplers 102f-j on connection member 116, when the connection member 116 rotates, the tubes 114 rotate in the passageway 110a of overhose 110, while the tubular lead member 118 may remain stationary. Tubular buoyancy devices, such as buoyancy device 104h, are provided on bars 104 that are connected to the upper portion of surface 102u on plate 102 such that when the system 100 is submerged in water, the connection member 116 will be held substantially in a predetermined position, such as position A illustrated in FIG. 1. In an exemplary embodiment, the plurality of tubes 114 include a means for transmission of a fluid, gas, electricity, or information. In an exemplary embodiment, the plurality of tubes 114 may, for example, include coaxial cable, fiber optic cable, a variety of other information conducting cables, pipelines, hoses, and an variety of other transmission means.

Referring now to FIG. 8a and 8b, an alternative embodiment of a termination system 300 is substantially identical in design and operation to the termination system 100 described above with reference to FIGS. 1-7 with the addition of a vessel 302 and a tubular umbilical 304, a portion of which replaces the overhose 110 of system 100, coupling the termination system 300 to the vessel 302. The tubular umbilical 304 defines a passageway 304a which allows tubes 114 to extend through tubular umbilical 304 and includes an outer coupling surface 304b for coupling the tubular umbilical 304 to the overhose coupling inner wall 108c on adapter 108. The plurality of bend limiters 112 may be coupled to an end of the umbilical 304.

Once the tubes 114 are extended through the passageway 304a defined by umbilical 304, at step 404, the tubes 114 are then extended through the passageway 108a defined by adapter 108, passageway 106b defined by collar 106, and through the holes 102a-e on plate 102 where they are coupled to the couplers 102f-j on connection member 116. With the tubes 114 coupled to the couplers 102f-j, at step 406, the collar 106 on connection member 116 is rotatably coupled to the adapter 108 on tubular lead member 118. With the collar 106 rotatably coupled to the adapter 108, the connection member 116 may rotate about the longitudinal axis 116a. With the tubes 114 coupled to the couplers 102f-j on connection member 116, when the connection member 116 rotates, the tubes 114 rotate in the umbilical 304, while the tubular lead member 118 and umbilical 304 may remain stationary. In an exemplary embodiment, the system 300 may then be situated beneath a body of water 306 while being coupled to the vessel 302. Tubular buoyancy devices, such as buoyancy device 104h, are provided on bars 104 that are connected to the upper portion of surface 102u on plate 102 such that when the system 100 is submerged in water, the connection member 116 will be held substantially in a predetermined position, such as position A illustrated in FIG. 8a.

Connector 502a includes a plurality of connections 502aa, corresponding to couplers 102f-j on connection member 116, which provide contacts for connections 102l-p on couplers 102f-j.

In an exemplary embodiment, during operation of the system 500, as illustrated in FIGS. 1, 2a, 2b, 3, 4, 5a, 5b, 6, 8a, 8b, 10, and 11, a method 600 for termination is implemented using the system 500 in which, in step 602, the plurality of tubes 114 are situated in and extended through the passageway 304a defined by umbilical 304. Once the tubes 114 are extended through the passageway 304a defined by umbilical 304, at step 604, the tubes 114 are then extended through the passageway 108a defined by adapter 108, passageway 106b defined by collar 106, and through the holes 102a-e on plate 102 where they are coupled to the couplers 102f-j on connection member 116. With the tubes 114 coupled to the couplers 102f-j, at step 606, the collar 106 on connection member 116 is rotatably coupled to the adapter 108 on tubular lead member 118. With the collar 106 rotatably coupled to the adapter 108, the connection member 116 may rotate about the longitudinal axis 116a. With the tubes 114 coupled to the couplers 102f-j on connection member 116, when the connection member 116 rotates, the tubes 114 rotate in the umbilical 304, while the tubular lead member 118 and umbilical 304 may remain stationary. When the connection member 116 is lined up with the connections 502aa on connector 502a, in step 610, the connection member 116 is connected to the connector 502a. In an exemplary embodiment, the system 300 may then be situated beneath a body of water 306 while being coupled to the vessel 302, and the connection to the undersea well system 502 may transmit information from undersea well system 502, through tubes 114, and up to vessel 302. Tubular buoyancy devices, such as buoyancy device 104h, are provided on bars 104 that are connected to the upper portion of surface 102u on plate 102 such that when the system 100 is submerged in water, the connection member 116 will be held substantially in a predetermined position, such as position A illustrated in FIG. 10a which substantially lines up connection member 116 to connect with connector 502a.
