A system, method, and devices are disclosed herein for feeding sections of conduit through a guide device which positions the conduit sections for bundling and then bundling the sections of conduit with a spacer device comprising a pair of brackets which encircle the conduit bundle and are banded together. In one implementation of the technology, a device for guiding conduit sections comprises an outer frame which encloses walls which intersect to form a grid. The grid comprises multiple channels through which multiple sections of conduit pass in parallel. In another aspect of the technology, a system of feeding and organizing multiple sections of conduit from conduit reels to a conduit guide and spacer system is provided.

In particular, the invention relates to a system for regulating the temperature of a cable which is laid at least partly in a body of water and on land, said system including: means for collecting water on the land-side such that water can be collected into said means and can be dispensed out of said means; means for controlling a quantity of water such that a quantity of water flowing out of the means for collecting water on the land-side or flowing into said means from the body of water can be controlled; and means for cooling a cable, said means surrounding the cable in the form of a sleeve in at least one section of the means for collecting water on the land-side up to a body of water, wherein a cavity through which the water flows in order to cool the cable is formed between the cable and the means for cooling the cable. The invention additionally relates to the use of a system according to the invention.

A duct-bank stub-up assembly includes a first pre-formed stub-up module that comprises a first plurality of conduits and a first encasing body. For each of the first conduits, a first end of the conduit provides a mating end on a mating side of the first encasing body and a second end of the conduit provides a mating end on a top surface of the first encasing body. The assembly further includes a second pre-formed stub-up module that comprises a second plurality of conduits and a second encasing body formed to have a stub-up section and a footer section. For each of the second conduits, a first conduit end provides a mating end on a mating side of the footer section and a second conduit end provides a mating end on a top surface of the stub-up section. The first module is positioned on the footer of the second module.

A power and communications cable may include an electromagnetic waveguide, an inner metallic tubular surrounding the electromagnetic waveguide, an electrically conductive material surrounding the inner metallic tubular, an electrically insulating material surrounding the electrically conductive material, and an outer metallic tubular resistant to corrosion and abrasion surrounding the electrically insulating layer. The example system may include an electrical device locatable in the wellbore and coupleable to the cable and a control unit coupleable to the cable and operable to supply power to and communicate with the electrical device via the power and communications cable.

A cable line includes a conduit having a tubular body, the wall of which is made of polymeric material, and an electrical cable provided with an outer sheath made of polymeric material and laid inside the conduit's body along its entire length. Herewith, the body wall is made with the provision of its electrically conductive properties, causing the possibility of current flow through the wall in the direction from its inner surface to the outer surface, furthermore the ratio of the diameter of the inner surface of the body wall to the diameter of the outer sheath of the cable is not less than 1.5.

A duct bank assembly may include an elongate extending conduit with a length for receiving and passing through a cable or wire and an encasing body encasing the conduit along its longitudinal extent between a first mating end and an opposed second mating end of the body. Each mating end of the at least one elongate conduit has a male or female mating end for joining with a corresponding male or female mating end of an abutting duct bank assembly in a self-locking, self-sealing joint.

A dadding tube (1) for enveloping an underwater conduit (2), such as a pipeline or a cable line, has at least one clamping portion (6), which comprises at least one deformation portion (6A, 6B, 6C) being integrally manufactured with the cladding tube (1), which deformation portion (6A, 6B, 6C) is a first wall portion of the cladding tube (1), which has a larger thickness in the radial direction than at least one second wall portion (8) of the clamping portion concerned, in such manner that by said larger thickness the first wall portion is, and the at least one second wall portion (8) is not, pressed against the underwater conduit (2) by a tensioning strap (7) being tensioned all round. The deformation portion concerned is easy to produce, durable and reliable. Thanks to the at least one clamping portion the dadding tube can be designed in harder and lower-cost materials than the soft, flexible poly urethane, which is usually applied nowadays.
