摘要： A method is provided that includes acquiring positional information regarding a pallet being translated on a conveyance system with an encoding sensor disposed proximate to the conveyance system. The method also includes receiving, with at least one processor, the positional information from the encoding sensor. Further, the method includes determining timing information using the positional information. The timing information corresponds to when a substrate disposed on the pallet will be in a print zone of a print head. The method further includes controlling the print head to print on the substrate when the substrate is in the print zone and passing beneath the print head.

摘要： A pipeline bundle for a riser tower or tie-back is manufactured offshore by suspending the bundle from an installation vessel, adding structural core sections successively to an upper end of the suspended bundle, lowering the bundle after adding each successive core section, and feeding one or more lengths of flowline pipe beside the core sections for incorporation into the bundle. The flowline pipe is coiled on a reel or carousel as a full-length piece before being uncoiled progressively as core sections are added to the lengthening bundle. The flowline pipe is then engaged with guide frames and/or buoyancy blocks supported by the core sections, by movement in a radially-inward direction through a radially-outer opening in a retainer formation. The opening is then closed to hold the flowline pipe in the retainer formation.

摘要： A system is provided that includes a print head, a conveyance system, an encoding sensor, and at least one processor. The print head defines a print zone, and is configured to print on objects within the print zone. The conveyance system passes through the print zone, and is configured to translate a pallet through the print zone. The encoding sensor is disposed proximate to the conveyance system, and is configured to be oriented toward the pallet and to acquire positional information regarding the pallet. The at least one processor is operably coupled to the print head and the encoding sensor, and is configured to: receive the positional information from the encoding sensor; determine timing information corresponding to when a substrate disposed on the pallet will be in the print zone; and control the print head to print on the substrate when the substrate is in the print zone.

摘要： A fairing device and method for the reduction of vortex-induced vibrations or motions, the minimization of drag about a substantially cylindrical element immersed in a fluid medium, comprising; a fairing rotatably mounted about the cylindrical element, the fairing comprising a shell with a mainly cylindrical cross-sectional shape with an outer diameter (D) following the outer diameter of the cylindrical element from an upward stagnation point of 0 degrees to at least +/−90 degrees, and which at +/−90 degrees continues as two fin-like portions in an aft direction, further comprising that the fin-like portions are convexly curved aft of +/−90 degrees thus tapering towards each other and defining a tail end opening or gap less than the fairing standoff height. A method for mounting, storage, and deployment of the fairing device is also disclosed.

摘要： A method of installing at sea a double-walled preheated undersea pipe for transporting fluids, wherein for each new pipe section to be assembled to a pipe that is already installed at sea: the method involves preheating the inner wall unit element inside the outer wall unit element of the new pipe section; assembling the inner wall unit elements of the new pipe section to the inner wall of the pipe that is already installed at sea; assembling the outer wall unit element of the new pipe section to the outer wall of the pipe that is already installed at sea; lowering the new pipe section into the sea; and repeating the above for other new pipe sections to be assembled so as to prestress the pipe while it is being installed at sea.

摘要： A method for assembly of a riser string onboard a vessel for performing subsea wellbore related operations involving said riser string, the riser string extending between a subsea wellbore and the vessel in a wellbore related operation, wherein the vessel includes a hull, a riser storage storing therein, in horizontal orientation, multiple pre-assembled riser stands and/or multiple individual riser stand, a deck structure having an elongated transfer opening above said riser storage, a transfer elevator, wherein multiple pre-assembled riser stands, each being pre-assembled from multiple riser sections connected end-to-end and each having a length of at least 150 ft. (45.72 m), and/or multiple individual riser sections each having a length of at least 150 ft. (45.72 m), are stored, in said horizontal orientation, in the riser storage.

摘要： A method for assembly of a riser string onboard a vessel that is adapted to perform subsea wellbore related operations involving said riser string, said riser string being configured to extend between a subsea wellbore and the vessel in a wellbore related operation, wherein the vessel including a hull, a riser storage adapted to store therein, in horizontal orientation, multiple pre-assembled riser stands and/or multiple individual riser stand, a deck structure having an elongated transfer opening above said riser storage, a transfer elevator, wherein multiple pre-assembled riser stands, each being pre-assembled from multiple riser sections connected end-to-end and each having a length of at least 150 ft. (45.72 m), and/or multiple individual riser sections each having a length of at least 150 ft. (45.72 m), are stored, in said horizontal orientation, in the riser storage, wherein the method comprises a riser transfer step wherein the transfer elevator is operated so as to raise a single one of said pre-assembled riser stands and/or individual riser sections in the horizontal position thereof from the riser storage, through the transfer opening, to a position above the deck structure.

摘要： Additive manufacturing of a pipe is disclosed. A lowering mechanism is configured to be coupled with respect to a platform and to lower a pipe through an opening in the platform. An extrusion head is configured to receive material and selectively extrude the material via a nozzle. A gantry is coupled to the extrusion head and is configured to move the extrusion head to an identified location. A controller is coupled to the gantry and configured to direct the gantry to move the extrusion head based on pipe data that identifies a geometry of the pipe. A stabilizer mechanism is configured to maintain the pipe in a desired position during the extrusion of the material.

摘要： A bend stiffener is operable to be installed on site in a collapsed state and expanded upon installation to provide increased coverage of a tubing string to be reinforced by the bend stiffener. The bend stiffener is expandable upon the tripping of tubing through the bend stiffener. The bend stiffener includes a flexible sleeve having an outer flange at an upper end and sized to receive the tubing. The bend stiffener also includes an intermediary sleeve and an external sleeve. The intermediary sleeve has a cylindrical body and an internal flange for engaging and supporting the outer flange of the flexible sleeve. Similarly, the external sleeve has an internal flange for supporting an external flange of the intermediary sleeve. When installed, the flexible sleeve slides from the intermediary sleeve and the intermediary sleeve slides from the external sleeve so that each sleeve encloses and reinforces a segment of tubing.
