A stab and hinge over (SHO) system, including: a guide system; a base structure disposed on a sea floor below a top side; and an umbilical termination assembly (UTA), the UTA comprising: a body coupled to the guide system, the body including an umbilical connection and internal circuitry; an umbilical configured to transmit information and power via electrical signals from the top side to the internal circuitry via the umbilical connection; a stab-in member, wherein the stab-in member is coupled to the body, the stab-in member is positionable in a retracted position and an extended position, wherein the stab-in member is rigidly coupled to the body in the retracted position, and wherein the stab-in member is pivotably coupled to and protruding from the body in the extended position; a retaining mechanism configured to retain the stab-in member in the retracted position when the retaining mechanism is engaged and configured to allow the stab-in member to be positioned in the extended position when the retaining mechanism is disengaged; and a guide rail, wherein a hinge couples a first end of the stab-in member to the body, wherein the hinge is slidably disposed in the guide rail, and wherein the hinge is positioned at a first position within the guide rail and a second end of the stab-in member is slidably disposed in the guide rail when the stab-in member is in the retracted position.
8. 8 . The SHO system of claim 7 , wherein when the retaining mechanism is disengaged, the stab-in member is pivotable about the first end.
9. 9 . The SHO system of claim 7 , wherein the guide rail extends axially along the body.
10. 10 . The SHO system of claim 7 , wherein the guide rail extends laterally across the body.
11. 11 . The SHO system of claim 7 , wherein in the extended position, the hinge is positioned at a second position within the guide rail such that the second end of the stab-in member is pivotable about the first end.
12. 12 . A method of engaging an umbilical termination assembly (UTA) with a subsea base structure, comprising: lowering the UTA, the UTA including a stab-in member, wherein the stab-in member is positionable in a retracted position and an extended position, wherein the stab-in member is rigidly coupled to a body of the UTA in the retracted position, and wherein a first end of the stab-in member is pivotably coupled to the body by a hinge and a second end of the stab-in member protrudes from the body in the extended position; positioning the stab-in member in the extended position, wherein positioning the stab-in member in the extended position includes sliding the hinge from a first position in a guide rail of the UTA to a second position in the guide rail, and wherein, in the first position, the second end of the stab-in member is retained in the guide rail and, in the second position, the stab-in member is pivotable about the hinge; and guiding the stab-in member into engagement with a receiving receptacle of the subsea base structure.
13. 13 . The method of claim 12 , further comprising disengaging a retaining mechanism of the UTA, wherein disengaging the retaining mechanism allows the stab-in member to be positioned in the extended position.
14. 14 . The method of claim 13 , wherein positioning the stab-in member in the extended position includes disengaging the retaining mechanism and pivoting the second end of the stab-in member about the first end.
