Abstract
A system for deploying a coil of spoolable pipe from a vessel includes a first tower configured to move longitudinally and transversely along a first track coupled to the vessel, a second tower configured to move longitudinally along a second track coupled to the vessel, and a coil drum assembly coupled to the first tower. The first tower is configured to insert the coil drum assembly transversely into an interior channel of the coil when the coil drum assembly is in a retracted position, the coil drum assembly is configured to support the coil when the coil drum assembly is in an extended position and rotate during deployment of the spoolable pipe, and the first tower and the second tower are configured to move the coil drum assembly vertically.
Claims18
A system for deploying a coil of spoolable pipe from a vessel, comprising:
- a first tower coupled to the vessel and configured to move along a surface of the vessel;
- and
- a coil drum assembly coupled to the first tower, wherein the first tower is configured to insert the coil drum assembly into an interior channel of the coil when the coil drum assembly is in a retracted position, the coil drum assembly is configured to support the coil when the coil drum assembly is in an extended position and rotate during deployment of the spoolable pipe, and the coil drum assembly comprises:
- a post;
- expandable spokes, wherein each of the expandable spokes extends away from the post and has a distal end movable between a retracted position and an extended position;
- first and second spoke frames mounted to the post, wherein each of the first and second spoke frames includes a plurality of the expandable spokes;
- a plurality of drum segments each mounted to the distal end of one of the expandable spokes of the first spoke frame and to the distal end of one of the expandable spokes of the second spoke frame, wherein the drum segments extend parallel to the post;
- and
- a plurality of mechanical actuators each extending between the post and one of the expandable spokes or one of the drum segments, for moving the expandable spokes between the retracted and extended positions.
A system for deploying a coil of spoolable pipe from a vessel, comprising:
- a first tower configured to move longitudinally and transversely along a first track coupled to the vessel;
- a second tower configured to move longitudinally along a second track coupled to the vessel;
- and
- a coil drum assembly coupled to the first tower, wherein the first tower is configured to insert the coil drum assembly transversely into an interior channel of the coil, the coil drum assembly is configured to support the coil and rotate during deployment of the spoolable pipe, the first tower and the second tower are configured to move the coil drum assembly vertically;
- and the coil drum assembly comprises:
- a post;
- expandable spokes, wherein each of the expandable spokes extends away from the post and has a distal end movable between a retracted position and an extended position;
- first and second spoke frames mounted to the post, wherein each of the first and second spoke frames includes a plurality of the expandable spokes;
- a plurality of drum segments each mounted to the distal end of one of the expandable spokes of the first spoke frame and to the distal end of one of the expandable spokes of the second spoke frame, wherein the drum segments extend parallel to the post;
- and
- a plurality of mechanical actuators each extending between the post and one of the expandable spokes or one of the drum segments, for moving the expandable spokes between the retracted and extended positions.
A method, comprising:
- moving a first tower coupled to a vessel and a coil drum assembly coupled to the first tower to a location of a first coil of spoolable pipe;
- moving the first tower to insert the coil drum assembly into an interior channel of the first coil to support the first coil;
- moving the coil drum assembly upwardly using the first tower;
- and
- rotating the coil drum assembly to deploy the first coil, wherein retracting or extending the coil drum assembly comprises actuating a plurality of mechanical actuators of the coil drum assembly each extending between a post of the coil drum assembly and one of expandable spokes of the coil drum assembly or one of drum segments of the coil drum assembly.
