A device for pulling a cable down the length of a cable tray including a trolley with rollers which rollingly grasp the upper side portion of the cable tray and allow the trolley to roll along the tray. The trolley includes a swivel cord grip which is releasably attached to one end of the cable, thus allowing the cable puller to pull the cable along the cable tray as the cable puller is propelled along the cable tray. The trolley can be pulled along manually by using one of two pull lines or jet lines which are attached to the cable puller and lead to each end of the cable tray, or, more preferably, the trolley can be propelled up or down the cable tray by a remotely controlled motor which drives one or more of the rollers.

Provided is an offshore structure, especially offshore wind turbine, including a platform that is connected to the seabed, especially via a foundation that carries the platform, and an appliance, wherein it comprises guiding means for guiding at least one tube or cable along a guidance path from a respective entry point at which the tube or cable enters the platform to a respective connection point at which the tube or cable is connected or connectable to the appliance.

A device for use in removing a conveyance member from a material includes a displacement element (12, 1012) and a self-propelling driving element. The displacement element (12, 1012) is for being placed at least partly around a conveyance member (16) and for displacing material as the displacement element (12, 1012) is advanced along a conveyance member (16). The driving element is coupled to and movable with the displacement element (12, 1012) to advance the displacement element along a conveyance member (16).

A cable installation apparatus includes a drive assembly and a cable assembly, wherein the apparatus dispenses the cable onto and/or into and along the inner surface of a tubular structure while being moved. The apparatus also includes a securing assembly for holding and dispensing a securing material component while the apparatus is being moved along the length of the tubular structure, wherein the securing material component secures the cable to the inner surface of the tubular structure after being dispensed from the apparatus. A cleaning assembly may also be included for cleaning portions of the inner surface of the tubular structure while the apparatus is being moved along the length of the tubular structure and before the cable is dispensed onto and/or into the portions of the inner surface of the tubular structure.

The present disclosure relates to a method for festooning a power cable while deploying it in a deployment site comprising a rail having a start and an end, the method comprising the steps of: providing the cable with a plurality of cable holders slidably movable along the rail, each two consecutive holders being spaced at a holder predetermined distance on the cable; providing a festooning apparatus after the start of the rail, the festooning apparatus comprising a lowering device movable between a raised position and a lowered position; deploying the cable along the rail by repeating the following sub-steps: engaging on the rail one holder after the other and moving them thereon; when one holder oversteps the festooning apparatus, operating the festooning apparatus to move the lowering device from the raised position towards the lowered position, thus engaging the cable at a point between two consecutive holders; when the lowering device reaches the lowered position, obtaining a sagged portion of cable and a shortening of the holder predetermined distance; operating the festooning apparatus to move the lowering device from the lowered position towards the raised position, thus disengaging it from the cable; fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged cable portion; and advancing the sagged cable portion along the rail.

A cable pulling device (1) having a capstan (6) extending from one side of a housing (11) that attaches to a boom (10) of a backhoe (5) via a quick coupling (8). The capstan is located on an external side of the housing in an offset and exposed manner that allows a rope (19) to be wrapped over and/or around the capstan. By pulling on the rope, an operator is able to control tension on the capstan, thereby allowing the capstan to provide a pulling force on the cable or one or more electrical wires being pulled through the conduit.

The invention relates to an apparatus for inserting a new pipe into an old pipe by means of a self-driven impact device, which simplifies the insertion of a new pipe into an old pipe, and wherein blocking elements of an apparatus according to the invention engage with the inside wall of an old pipe in order to prevent any movement of the self-driven impact device in a direction opposite the direction of advance, as well as a method for using the device. The apparatus according to the invention has blocking elements, which are disposed on at least one base body, but preferably four base bodies, which are in turn releasably mounted on the self-driven impact device. This method is characterized in that the base bodies together with the blocking elements and the self-driven impact device are salvaged by the new pipe.

A method of deploying cabling in a tray using an automated cable runner (ACR). The ACR includes a pathway, a carriage operable to travel along the pathway, a plurality of supports connectable to the pathway and connectable to the tray and configured to support the pathway over the tray, and a cabling holder attached to the carriage. The carriage includes a drive wheel structured and arranged to contact the pathway, a motor operable to rotate the drive wheel, and a power source connected to motor. The method includes attaching the carriage to the pathway, connecting an end of a cabling to the cabling holder, and powering the motor to rotate the drive wheel to drive the carriage to travel along the pathway from a desired start point to a desired end point to deploy cabling into the tray from the start point to the end point.

An anchor structurally configured to enhance pulling of a cable during installation may include a cable coupling portion configured to grip a cable. The cable coupling portion may include a body portion and a gripping portion, the body portion may include a cable receiving portion structurally configured to permit a cable to pass through the body portion, and the gripping portion may be structurally configured to engage a cable received in the cable receiving portion. The gripping portion may be structurally configured to engage at least a portion of an outer surface of a jacket of a cable received in the cable receiving portion such that the cable coupling portion is configured to transfer a pulling force applied to the cable coupling portion by a coupled pulling carrier to the cable so as to enhance pulling of the cable during installation of the cable.
