Abstract
System for use in building and deployment of an elongate element (202) in a J-lay operation. The system includes an upright structure (206); a winching element (204) retractable along an axis within the upright structure (206); a coupling element (210) connected to the winching element (204), for coupling the winching element (204) to an elongate element (202); and a catcher element (212) configured to retain the coupling element (210) in alignment with a predetermined axis within the upright structure (206) during retraction or extension of the winching element (204).
Claims25
A system for use in building and deployment of an elongate element in a J-lay operation, comprising:
- an upright structure;
- a winching element retractable along an axis within the upright structure;
- a coupling element connected to the winching element, for coupling the winching element to an elongate element;
- and
- a catcher element configured to retain the coupling element in alignment with a predetermined axis within the upright structure during retraction or extension of the winching element.
A system for use in building and deployment of an elongate element in a J-lay operation, comprising:
- an upright structure;
- a first and second clamping element, each clamping element traversable along the upright structure;
- an actuating element configured to control movement of the first clamping element with respect to the upright structure;
- wherein the second clamping element is configured to couple with the first clamping element so that, when coupled together, the actuating element can control movement of both the first and the second clamping elements with respect to the upright structure.
A method for building and deploying an elongate element in a J-lay operation, comprising:
- providing a system comprising:
- an upright structure;
- a first and second clamping element, each clamping element traversable along the upright structure;
- an actuating element configured to control movement of the first clamping element with respect to the upright structure;
- the method further comprising coupling the second clamping element with the first clamping element;
- and
- actuating the actuating element to control movement of both the first and second clamping elements with respect to the upright structure.
A reel-lay system for the use in the building and deployment of an elongate element, comprising:
- an upright structure;
- a clamping element traversable along the upright structure;
- and
- a workstation for providing access to an elongate element within the upright structure;
- wherein the workstation is coupled to the clamping element such that the workstation is traversable along the upright structure via the clamping element.
