Abstract
Aspects of the present disclosure provide an umbilical termination assembly (UTA). The UTA including a body, an umbilical, and a stab-in member. The body including an umbilical connection and internal circuitry. The umbilical is configured to transmit information and power via electrical signals from a top side to the internal circuitry via the umbilical connection. The stab-in member is coupled to the body. The stab-in member is positionable in a retracted position and an extended position. The stab-in member is rigidly coupled to the body in the retracted position and the stab-in member is pivotably coupled to and protruding from the body in the extended position.
Claims15
An umbilical termination assembly (UTA), comprising:
- a body, the body including an umbilical connection and internal circuitry;
- an umbilical configured to transmit information and power via electrical signals from a top side to the internal circuitry via the umbilical connection;
- and
- 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;
- 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.
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.
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.
