A one-connector penetrator system that is adaptable to any cables used in artificial lift system is described herein. The one-connector penetrator system can comprise an enclosure and a plurality of seals. The enclosure can have a hollowed interior. The plurality of seals can be housed within the enclosure. The plurality of seals can stabilize a three-phase power cable in a fixed position. The plurality of seals can comprise a first seal, a second seal, and a third seal. The first seal can be placed at the front-end portion of the enclosure. The second seal can be placed within the middle portion of the enclosure. The third seal can be placed at the bottom portion of the enclosure.

A subsea umbilical termination assembly comprising: an umbilical termination head fixed to the end of a subsea umbilical; and an electrical and/or optical distribution unit comprising a base frame and several connectors mounted to the base frame, wherein each connector is electrically connected to an electrical cable of the subsea umbilical via the umbilical termination head or optically connected to an optical cable of the subsea umbilical via the umbilical termination head. The umbilical termination head is mounted in a space provided inside the base frame of the distribution unit.

A system for communicating through a hanger can include an alignment manifold having upper and lower terminals positioned on opposite respective sides of the alignment manifold, each of the upper terminals being in communication with a respective one of the lower terminals. A downhole line connector can be configured to connect to downhole lines, the downhole line connector including terminals aligned with the lower terminals of the alignment manifold. A method of communicating through a hanger can include connecting an alignment manifold to the hanger, the hanger being configured to suspend a tubular from a wellhead assembly, and connecting a downhole line connector to the alignment manifold.

A sacrificial breakaway mechanism comprising: a first piece attached to a fixed structure; a second piece; a plurality of connectors running between the second piece and the fixed structure; and a sacrificial element connecting the first piece to the second piece, wherein the sacrificial element is configured such that a tensile load exceeding a predetermined threshold exerted on the second piece causes the sacrificial element to break, separating the first piece from the second piece and allowing relative movement therebetween, the relative movement causing a sequential disconnection of the plurality of connectors.

A field attachable submersible pump cable connector assembly for an electrical connection in a well head, allowing for direct connector assembly to the ESP cable eliminating the cable to cable splice. The connector assembly permits the use of standard crimping pliers to crimp the ends of a heavy gauge multi-conductor cables typically used for electric submersible pump (ESP) cables to the power pin for connection to an electrical power source external to the well head. The connector assembly protects the crimped connection from contaminants and the corrosive environment within the well head.

A wet connect apparatus operable in a down-hole environment includes an annular electrical contact, which includes a resilient outer member constructed of coiled spring having its ends fused together, and also includes an inner retention member constructed of a gift ring embedded or installed within the resilient outer member. The inner retention member provides a radial bias to retain the annular electrical contact within an electrically conductive groove during installation and assembly of the wet connect apparatus.

A method for determining an operational state of a subsea connector unit, wherein the method includes: providing at least one operational value and/or a plurality of operational values of at least one operational parameter describing a specific operational condition at at least one selected location of the subsea connector unit and comparing the at least one provided operational value and/or the plurality of provided operational values and/or at least one derivative derived from the at least one provided operational value and/or at least one derivative derived from the plurality of provided operational values with at least one predefined reference and thus determining an operational state of the subsea connector unit on the basis of the comparison. An assembly monitors an operational state of a subsea connector unit and a subsea connector unit has the assembly.

Systems and methods providing a tree cap that allows power, signal, and/or hydraulic function connections to be established between an Electrical Submersible Pump and a vertical Christmas tree (VXT) control system are provided. The tree cap includes an Electrical Feed-through System (EFS) having an electro-hydraulic stinger configured to form a connection to an ESP hanger plug of the Electrical Submersible Pump (ESP). The tree cap is configured to lock onto the vertical Christmas tree (VXT) and provide a secondary seal barrier element to the environment.

A component of a subsea connector includes a conductor, an electrically insulating layer and an at least partially electrically conductive layer. A method of assembling the component includes providing the insulating layer radially outward of the conductor; and applying the at least partially conductive layer onto the insulating layer by casting, moulding, compression fitting, or additive manufacturing techniques.
