摘要： A field joint transfer system for transferring a hot field joint along a curved path between a tensioner and a stinger during deployment of a pipeline from a pipelay vessel. The system comprises a plurality of adjustable pipe support units defining a curved path between the tensioner and the stinger, wherein one or more of the pipe support units can be moved out of engagement with the pipeline to allow the hot fieldjoint to pass the respective pipe support unit without contact, while maintaining support for the pipeline along the curved path. A mobile pipe support may be provided on an overhead gantry to follow the pipe as it passes along the curved path.

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： The present invention regards an apparatus for unwinding flexible cables on seabeds, which comprises: two first towers (2), each provided with a corresponding first vertical guide seat (5), two second towers (6), each provided with a second vertical guide seat (7), and two hub-holder groups (8), each of which slidably constrained to the second guide seat (7) of the corresponding second tower (6) and carrying, rotatably mounted thereon, a corresponding hub (3). Each second tower (6) can be moved between a first operating configuration, in which the second tower (6) is slidably constrained in the first guide seat (5) of the corresponding first tower (2), and a second operating configuration, in which the second tower (6) is arranged outside the first guide seat (5) of the corresponding first tower (2).

摘要： A buoyant conduit storage system comprising a reel for storing conduit and a drive arrangement for rotating the reel. The reel is rotatable about a substantially vertical axis of rotation to reel and/or unreel the conduit. The drive arrangement drives the reel at the axis of rotation. The buoyant storage system may provide for the storage and/or transportation and/or deployment of reelable conduit.

摘要： A resting device (1) of at least one portion of a linear structure (2) is for crossing an uneven underwater topography. The resting device (1) is suitable for supporting at least one portion of the linear structure (2) that defines a longitudinal direction (X-X) coincident with or parallel to the longitudinal development direction of the linear structure (2). The resting device (1) includes at least one buoyant element (3) and at least one tether (4), suitable for constraining the resting device (1) to a bed (5). The at least one buoyant element (3) is suitable for providing a sufficient buoyancy to keep the at least one tether (4) under tension. A deck (6) has a shape and material that allows distributed resting of at least one portion of the linear structure (2) on the resting device (1).

摘要： Apparatus and methods related to pipeline freespan support are described. For example, some embodiments may contain an upper structure, which contains at least four legs connected to one another by a number of bracing members, and a number of attachment points through which the upper structure can be lifted, and a lower structure, which contains at least four posts that can be connected to, and disconnected from as needed, the four legs of the upper structure, two spaced mud mats on which the posts stand, and at least two horizontal arms that can be attached to the posts, rotate about the posts, connect to and be locked with the posts on the other mud mat, and be lifted to an appropriate height to provide suitable support at the pipeline freespan location.

摘要： In general, a conductor removal system 1 comprises a conductor sectioning tower which can be used to automate lifting and landing of various conductor sections. In most embodiments, the conductor sectioning tower can selectively and controllably go between an initially compact position to a raised, substantially vertical position with respect to the conductor removal system's transport frame. Conductors are cut creating a severed conductor section which can be positioned onto a conductor landing cart for further removal processing.
