An apparatus method and system are enable sending fluid to a receiver when a main line for the fluid in an umbilical is faulty. The apparatus has: first and second inlet lines and a first outlet line; A first inlet connector connects the main line for the fluid in the umbilical to the first inlet line and a second inlet connector connects a second line to the second inlet line; An outlet connects a receiver to the apparatus and has a first outlet connector connecting the receiver for the fluid; A switch mechanism for switches from a default setting wherein the first inlet line leads to the first outlet connector through the first outlet line to a secondary setting wherein the second inlet line leads to the first outlet connector through the first outlet line for enabling transferring the fluid through the second inlet line to the first outlet connector.

In a subsea blowout preventer stack system with a lower marine riser package with a lower marine riser connector and choke and/or kill lines, and a lower blowout preventer stack with a mandrel on the upper end and choke and/or kill lines connection to choke and kill valves, a method of porting the choke, kill lines, hydraulic lines and electrical lines vertically through the wall of the lower blowout preventer stack mandrel.

An electrical feedthrough assembly has a lower assembly having a first end and a second end. The lower assembly includes an outer body with a lower housing and an upper housing disposed within a bore of the outer body and a first conductor extending from the lower housing to the upper housing. Additionally, the lower housing extends axial outward from the outer body to form the first end and the upper housing extends axial outward from the outer body to form the second end. Further, the electrical feedthrough assembly has an upper assembly having body extending from a first end to a second end. The second body includes a pin end at the first end inserted into an opening of the second end of the lower assembly. A second conductor is disposed within the body. A piston is disposed within the body configured to move the second conductor.

An improved wellhead electrical connection assembly utilizing upper and lower retention mechanisms to minimize pressure and fluid leakage in the event of a tubing part or other failure. The upper retention mechanism ensures the connection assembly remains within a tubing hanger. The lower retention mechanism provides a secure connection to a downhole cable that can breakaway without damaging or dislodging other components of the assembly during an emergency event.

In a subsea blowout preventer stack system connected to the surface with a drilling riser and with one or more control pods for control of the subsea blowout preventer stack, a method of providing a control umbilical of near neutral weight in the ocean water to provide control signals to the one or more control pods comprising providing a core of conductors such as wires and optical fibers, providing a flexible outer core comprising a mixture of resilient material and buoyant materials, providing a connector on the lower end of the umbilical.

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.

A wet Christmas tree (WCT) is segmented into a lower safety module containing safety valves and an upper multifunctional module for controlling the flow and/or pumping and/or subsea processing. The WCT can be applied to completion systems using completion mode with tubing heads or directly on the wellhead. The modular WCT can be used in oil and gas production well applications or injection of water and/or gases in subsea fields in shallow water to deep water.

A subsea housing assembly has a subsea housing with a first and a second housing portion. The first and second housing portions have first and second electrical connections for data communication. A wall separates the first and second housing portions. The assembly has an inductive coupler with first and second coupling sections disposed in the first and second housing portions. The inductive coupler provides inductive coupling across the wall for data communication between the first and second electrical connections. The inductive coupler has inner and outer coils wherein the outer coil at least partly surrounds the inner coil and at least part of the wall extends between the inner and outer coil. Soft magnetic material is arranged around the outer coil and/or inside the inner coil such that the magnetic flux is collected and guided from the outer to the inner coil and/or from the inner to the outer coil.
