    Abstract: In a pipe joint, a spigot is inserted into a socket; a lock ring is accommodated in a lock ring-accommodating groove formed in the inner circumference of the socket; and an engaging part formed in the outer circumference of the spigot, wherein the engaging part engages with the lock ring from a back side of the socket in a separation direction A of the spigot, thereby preventing the spigot from separating from the socket. The engaging part is formed at a position receding from a distal end of the spigot in the separation direction A of the spigot. A bending suppressing member for restricting the socket and the spigot in a bending direction C is provided between the inner circumference of the socket and the outer circumference of the spigot in the range between the distal end of the spigot and the engaging part.

    Abstract: A subsea pipeline (14) has a friction-reducing outer coating, treatment or finish (30) that extends along discrete regions mutually spaced along the length of the pipeline. During laying, curvature is imparted to the pipeline (14) along its length, for example by the residual curvature method or by snake-lay, to create expansion loops (26) of increased curvature relative to intermediate portions (28) of the pipeline (14) that join those loops (26). Each of the loops (26) is coincident with a respective one of the regions that bear the friction-reducing outer coating, treatment or finish (30). This facilitates lateral movement of the loops (26) relative to the seabed (16) to mitigate and control buckling in use of the pipeline (14).

    Abstract: A method for protecting a novel anti-drop submarine cable includes: assembling a traction assembly, a standard bending protection section and a protection reinforcement section sequentially to form a submarine-cable-protection device, and a submarine cable passing through it; connecting a traction rope of the traction assembly to a reserved traction rope pre-buried in a single pile foundation, and enabling the submarine cable and the submarine-cable-protection device by a traction device passing through a reserved hole of the foundation; moving the assembled sets forward until the traction rope is lifted and unmovable, enabling a retaining ring of the protection reinforcement section to abut against the reserved hole, installing the traction rope on the foundation by shackles; pulling the reserved traction rope to a proper length, fixing the submarine cable to installation base. The safety is ensured by avoiding dropping of the submarine-cable-protection device, and ensures the overbending protection of the submarine cable.

    Abstract: A device and method for the creation of a water proof component void form unit to create space between concrete structures and expansive soil for the passage of utility conduit lines is described. The unit includes a plurality of panels interlocked with one or more connectors and supports that pass internally through flutes within the panel members. The void space is formed from a singular panel that is scored along a score line. The score line passes only through an upper surface. The panel member is folded about the lower surface at the score line to form the void space. The panels are located in a trench and configured to define a void space underground for the passage of the utility conduit lines. The unit is configured to resist soil expansive forces so as to protect the placement and integrity of the utility conduit lines.

    Abstract: A non-metallic clip connection system includes a non-metallic clip having a substantially rectangular base portion, a first longitudinal flared wing portion, and a second longitudinal flared wing portion, wherein a plurality of edges of the clip along a path of insertion are beveled or radiused. The non-metallic clip connection system also includes a first non-metallic member having a first portion of a non-metallic clip receiver and a second non-metallic member having a second portion of the non-metallic clip receiver. The first non-metallic member is secured to the second non-metallic member by inserting the non-metallic clip in the non-metallic clip receiver. A non-metallic vertebrae bend restrictor and a non-metallic vertebrae end piece may use a non-metallic clip connection system.

    Abstract: Devices, systems, and methods are directed to formation of tubular structures, such as spirally formed structures, having spirally extending reinforcing material. In particular, tubular structures can be formed in a continuous process in which a first material is spiral formed along a first spiral and a second material is joined to the first material along a second spiral to reinforce the spirally formed first material. As compared to manual application of reinforcing material, such a continuous process can facilitate producing tubular structures at rates suitable for high-volume, commercial fabrication. Further, or instead, as compared to the use of circumferentially extending reinforcing material to support a spiral formed tube, reinforcing the spirally formed first material with a spiral of the second material may offer certain structural advantages, such as improved resistance to buckling.
