09657869 · 2017-05-23 · ·

A house connection for a cable in a medium conduit comprises a cable passage with which the cable is taken out of the medium conduit. The cable passage is provided with a cable tensioner with which a portion of the cable can be tensioned in the medium conduit. The cable passage is preferably part of a rotatable manifold.

Method and equipment for installing a power cable in a deployment site

Method and Equipment for Installing a Power Cable in a Deployment Site The present disclosure relates to a method for installing a single power cable span in a deployment site comprising a rail for supporting the single cable span by trolleys, the method comprising the steps of providing a conveyor belt outside of the deployment site, the conveyor belt having a plurality of locations set at a predetermined distance one from the other along a longitudinal movement direction of the conveyor belt and moving integrally with the latter; repeating the following steps until the single cable span reaches a predetermined position while the conveyor belt is moving, positioning a first part of a holder at one of the locations; while advancing the single cable span, laying a portion thereof on said first part of the holder positioned at the location moving with the conveyor belt; connecting a second part of the holder to the first one to lock the cable span portion in between; while the cable span portion locked by the holder is leaving the conveyor belt, removing the first part of the holder from the location moving with the conveyor belt. According to another aspect, the present disclosure relates to an equipment for the installation of a single power cable span in a deployment site.

Electrically conductive fiber optic slickline for coiled tubing operations

A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads that may be surrounded by an electrically conductive member such as split half shells of copper elements. Further, these features may be disposed in a filler matrix so as to provide a cohesiveness the core of the slickline. So, for example, the line may be more effectively utilized in downhole applications such as coiled tubing operations, without undue concern over collapse or pinhole issues emerging in the line.

Optical and Electrical Composite Cable for Simultaneous Installation within Pipelines and Processing and Construction Methods Thereof
20260118613 · 2026-04-30 ·

This application discloses an optical and electrical composite cable designed for simultaneous installation within pipelines, along with its processing and installation methods. By providing a composite cable with a thin wall and compact overall size, it allows the commercially available thin pipelines ranging from 6 mm to 13 mm in diameter to accommodate both optical and electrical cables in a single pass. This design reduces the amount of pipeline material needed and shortens installation time, while broadening the potential applications for these types of pipelines and improving their utilization. Since the optical and electrical composite cable is installed within a pipeline, it does not require self-supporting overhead structure, which simplifies its design. The thinner optical cable is connected to the thicker electrical cable, allowing the electrical cable to provide necessary tensile strength to the optical cable. This simplified approach to tensile strength ensures that the composite cable meets required strength standards despite its smaller size.
