Abstract: A guide apparatus 10 for an elongate member. The guide apparatus 10 comprises a plurality of elements 12 locatable along the length of the elongate member. Each element 12 extends around the elongate member. The guide apparatus 10 comprises a plurality of elongate link members 14 extending between elements 12. The elongate link members 14 are spaced from each other around the elements 12. The elongate link members 14 permit limited relative movement of the respective elements 12, such that the guide apparatus 10 permits limited bending of the elongate member. The guide apparatus 10 comprises a plurality of spacers 16. The spacers 16 are disposed between the elements 12. The spacers 16 extend around the elongate member. The spacers comprise guide formations 18, through which guide formations 18 the elongate link members 14 extend between the elements 12.

Abstract: Protection apparatus for a flexible elongate member. The apparatus comprises a plurality of protection members 10. Each protection member 10 defines an opening 22 through which a flexible elongate member can extend. Each protection member 10 is interconnectable end to end with other such protection members 10 to provide protection along the length of an elongate member. Each protection member 10 comprises two parts 12 which are mountable together to define the opening 22 through which an elongate member can extend. The two parts 12 together form a female formation 18 at one end, and a male formation 20 at the other end, such that the female formation 18 can receive a male formation 20 on an adjacent protection member 10 to interconnect the adjacent projection members 10. The female and male formations 18, 20 are configured to permit a predetermined amount of relative pivotal movement between adjacent protection members 10.

Abstract: Embodiments of the disclosure include methods and apparatus for a shroud that permits efficient installation and removal thereof from a flange of a pipeline. In one embodiment, a shroud is disclosed that includes a cover structure, and a plurality of retaining members coupled to an interior surface of the cover structure. Each of the plurality of retaining members comprises a rectangular arm coupled to a hinge structure, the hinge structure comprising a spring that fixes the rectangular arm in a position that is substantially orthogonal to a plane of the interior surface, wherein the hinge structure allows movement of the rectangular arm in a first direction and temporarily prevents movement of the rectangular arm in a second direction opposite to the first direction.

Abstract: A method and apparatus for detecting pipe entrenchment or upheaval of a flexible pipe and/or the presence of an external feature to the flexible pipe. The method includes helically winding a temperature sensing element around a layer of a flexible pipe, helically winding a heating element around a layer of a flexible pipe, heating the heating element to a pre-determined temperature, measuring the temperature at at least two locations along the flexible pipe, comparing the measured temperature response at the at least two locations, and making a determination, from the comparison of measured responses, regarding the exterior vicinity of the pipe at one of the at least two locations.

Abstract: Vortex Induced Vibration (VIV) suppression strakes, in particular VIV suppression strakes are arranged on subsea pipelines. A VIV suppression strake assembly includes a strake fin support shell that is configured to be arranged against the outer surface of a section of pipe and at least one strake fin having a fin tip and a fin base. The strake fin support shell includes an aperture that is configured for inserting the fin therein, and the fin is provided at the fin base with an anchor, which anchor is configured for engaging the fin support shell on the pipe side of the aperture. The aperture is a slot dimensioned to allow the fin to be inserted in the slot from the pipe side of the slot with the fin tip leading until the fin base engages the shell.

Abstract: A transfer mechanism (28) for transferring a fitting (46) on a flexible tubular conduit (48) about a guiding means (26) of a pipelay tower (20). The transfer mechanism (28) includes a frame (30) adapted to rotate about said guiding means (26); and a clamping mechanism (34) connected to the frame (30) and adapted to connect and secure the fitting (46) to the transfer mechanism (28). Actuation of the transfer mechanism (28) is configured to rotate the frame (30) about the guiding means (26) and cause at least one part of a fitting (46) connected to the transfer mechanism (28) to move along a path outside a surface of the guiding means (26) from a first position upstream of the guiding means (26) to a second position downstream of the guiding means (26).
