  • Publication number: 20220285052
    Abstract: A method for preparing an electrical cable may include coupling an injection barrel to an electrical cable that includes one or more conductors surrounded by a porous insulating material. The method may also include injecting epoxy resin into a chamber of the injection barrel, and the chamber may be fluidly coupled to an end face of the porous insulating material. Additionally, the method may include pressurizing the chamber such that the epoxy resin is forced to penetrate into the end face of the porous insulating material and removing the injection barrel to expose an epoxy-injected portion of the porous insulating material.

  • Patent number: 9834997
    Abstract: A connection release system for the disconnection of various connections, such as electrical, hydraulic, optical, and/or multi-connector, to a service tool in a high pressure environment. An embodiment of the connection release system includes a first and second housing portion with a piston disposed partially within both the first and second housing portions, the piston having a plurality of threads at an exterior portion of a second end. The system further includes a plurality of fluid chambers disposed in the first housing portion, the fluid chambers are filled with fluid to pressure-balance the piston such that the addition of a pressurized fluid to the pressure-balanced piston causes the piston to move, the exterior threaded portion of the piston to disengage an interior threaded portion within the housing second portion, and allow the first housing portion to separate from the second housing portion.

  • Patent number: 8545244
    Abstract: A technique facilitates the reliable connection of cables in subsea environments. A cablehead system is designed to reliably connect cables to subsea components while providing long term protection of the connection in potentially harsh, subsea environments. The cablehead system comprises a cable clamp housing which may be coupled to a bulkhead assembly by a cavity housing which provides space for routing of internal communication lines. One or more additional protective components are incorporated into the cablehead system to ensure a reliable connection and to further protect the internal communication lines from exposure to the surrounding environment.

  • Patent number: 7731515
    Abstract: An electrical connector is provided for use in establishing watertight connections, such as for subsea applications. The connector comprises a receptacle component (100) that includes a fluted, insulated male contact pin (52) with an isolation tube (5) substantially surrounding the insulated male contact pin over at least part of its length and containing oil therein, and a plug component (200) that includes a sliding contact pin assembly (19) and a release mechanism (40). The release mechanism (40) enables linear tolerance sliding action between the receptacle component and the plug component after establishing electrical communication between the mating components. The sliding contact pin assembly further includes a shuttle pin (24) that is urged rearwardly during mating to operate the release mechanism, thereby allowing the male contact pin and front contact band (20) to move relative to the central spring support rod (30) of the plug component.

  • Patent number: 7520768
    Abstract: A connector for a connection assembly for providing electrical power to a submersible electrical component in a deepwater environment, such as a subsea well, includes a ceramic body having a metallized inner passageway. A conductive contact extends through the passageway and has a contact end and a cable connecting end. A conductive sleeve is disposed about an outer surface of the ceramic body. The ceramic body is retained within a connector housing that has an interface chamber and a cable retaining chamber. The contact end of the connector contact is disposed within the interface chamber, and the cable connecting end of the contact is disposed within the cable retaining chamber. The sleeve is attached to the housing to provide a seal between the interface chamber and the cable retaining chamber. When the connector is engaged with a complementary connector, a Faraday cage is provided within the interface chamber to manage the electrical field about the connection interface between the connectors.
