  • In an exemplary embodiment, during operation of the system 100, as illustrated in FIGS. 1, 2 a, 2 b, 3, 4, 5 a, 5 b, 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 110 a defined by tubular overhose 110. Once the tubes 114 are extended through the passageway 110 a, at step 204, the tubes 114 are then extended through the passageway 108 a defined by adapter 108, passageway 106 b defined by collar 106, and through the holes 102 a-e on plate 102 where they are coupled to the couplers 102 f-j on connection member 116.

Once the tubes 114 are extended through the passageway 304 a defined by umbilical 304, at step 404, the tubes 114 are then extended through the passageway 108 a defined by adapter 108, passageway 106 b defined by collar 106, and through the holes 102 a-e on plate 102 where they are coupled to the couplers 102 f-j on connection member 116. With the tubes 114 coupled to the couplers 102 f-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 116 a. With the tubes 114 coupled to the couplers 102 f-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 104 h, are provided on bars 104 that are connected to the upper portion of surface 102 u 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. 8 a.
  • Referring now to FIG. 10 a and 10 b, an alternative embodiment of a termination system 500 is substantially identical in design and operation to the termination system 300 described above with reference to FIGS. 1-9 with the addition of an undersea well system 502 with a connector 502 a on a surface 502 b of undersea well system 502. Connector 502 a includes a plurality of connections 502 aa, corresponding to couplers 102 f-j on connection member 116, which provide contacts for connections 102 l-p on couplers 102 f-j.

Once the tubes 114 are extended through the passageway 304 a defined by umbilical 304, at step 604, the tubes 114 are then extended through the passageway 108 a defined by adapter 108, passageway 106 b defined by collar 106, and through the holes 102 a-e on plate 102 where they are coupled to the couplers 102 f-j on connection member 116. With the tubes 114 coupled to the couplers 102 f-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 116 a. With the tubes 114 coupled to the couplers 102 f-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 502 aa on connector 502 a, in step 610, the connection member 116 is connected to the connector 502 a. 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 104 h, are provided on bars 104 that are connected to the upper portion of surface 102 u 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. 10 a which substantially lines up connection member 116 to connect with connector 502 a.
