Definitions

  • the present invention relates to a subsea housing assembly and to a subsea sensor.
  • Subsea sensors such as temperature sensors or pressure sensors are essential components of any subsea processing facility.
  • a subsea sensor may for example be mounted to a pipe section through which a process fluid flows, such as a gas, a liquid, or a multiphase fluid which can include gaseous, liquid and solid constituents.
  • the process fluid pressure in some applications can be very high, for example in excess of 1,000 or 1,400 bar. While it is important for the process of extracting the process fluid to measure those high pressures with high accuracy it is similarly important to ensure that no process fluid leaks into the seawater under any circumstances.
  • US patent application US 2010/011853 A1 discloses a sensor cartridge comprising a protective housing having a single housing portion which is resistant to a down-hole oilfield environment and houses a sensor which is able to measure a parameter of the down-hole oilfield environment.
  • the sensor cartridge is attachable to another sensor cartridge and/or a hub and comprises a data communication unit within the protective housing, the data communication unit providing wireless communication of the measured parameter to the other sensor cartridge and/or the hub.
  • the wireless data communication can be an electromagnetic communication if the housing is non-metallic or an acoustic or optical communication if the if the housing is metallic.
  • the sensor cartridge has a power unit within the protective housing providing power to the sensor and/or the data communication unit.
  • the power unit may provide power by means of an incorporated battery or via inductive coupling.
  • the sensor cartridge is lowered into the well.
  • the housing's sole purpose is to protect the sensor, the data communication unit and the power unit from the down-hole environment.
  • the housing does not provide a separation between process fluid and seawater. Consequently, if the housing breaks the sensor will be destroyed but there will not be a leaking of process fluid into seawater.
  • European patent application EP 3269921 discusses a subsea housing assembly having a wall 30 providing a separation between a first housing portion 10 and a second housing portion 20 wherein a data communication is being provided between the first and second housing portions, through said wall, by way of inductive coupling 50.
  • the wall is integrally formed with a housing body 12 and the coils 51, 52 forming the inductive coupler are placed on either side of the wall.
  • housing body 12 and wall 30 are typically made of metal having a certain minimum thickness in order to withstand the high pressures the performance of the inductive coupling will generally not be optimal.
  • a subsea housing assembly comprising a subsea housing having a first and a second housing portion.
  • the first housing portion comprises a first electrical connection for data communication and the second housing portion comprises a second electrical connection for data communication.
  • a wall provides separation between the first housing portion and the second housing portion.
  • the subsea housing assembly further comprises an inductive coupler comprising a first coupling section disposed in the first housing portion and a second coupling section disposed in the second housing portion.
  • the inductive coupler is configured to provide inductive coupling across the wall for providing at least a data communication between the first electrical connection and the second electrical connection.
  • the inductive coupler further comprises a magnetic coupling element which traverses the wall and extends into the first housing portion and into the second housing portion, wherein the magnetic coupling element is made from a material different than that of the wall.
  • the wall is a pressure barrier configured to resist a predetermined minimum pressure difference across the wall.
  • the inductive coupler may further be configured to inductively supply electrical power from the electrical connection in the second housing portion to the electrical connection in the first housing portion.
  • the magnetic coupling element may be mounted in the wall by way of an interference fit such as a press fit or a shrink fit.
  • the magnetic coupling element may be welded to the wall. It should be noted that the interference fitting and the welding can be combined to improve pressure resistance of the joint.
  • the thickness of the wall may increase near the joint so as to increase the area of contact between the wall and the coupling element.
  • the magnetic coupling element is made of soft magnetic material, preferably soft iron.
  • the wall is made of a non-magnetic material, preferably a non-magnetic metal, for example Iconel 625.
  • the first coupling section and/or the second coupling section of the inductive coupler comprise(s) at least one respective coil arranged on a respective section of the magnetic coupling element.
  • the coil in the second housing section may be driven by an AC current that can be modulated for data communication.
  • the resulting electromagnetic field can induce a magnetic flow in the magnetic coupling element which in turn can induce a current in the coil of the first coupling section in the first housing portion.
  • Electrical power and data communication signals (which can include control signals) may thus be transferred into the first housing portion.
  • a modulated current can be provided to the coil of the first coupling section, which induces a respective magnetic flow in the magnetic coupling element which in turn induces a respective current in the second coupling section, for example for transferring sensor data or the like.
  • the magnetic coupling element is essentially cylindrical and extends into both housing sections such that the first and second coupling sections, including any number of coils, can be mounted in full on respective ends of the magnetic coupling elements.
  • the cross section of the magnetic coupling element does not need to be constant over its length; for example the diameter may vary in the case of an essentially circular cross section so as to improve the magnetic flux.
  • a subsea sensor comprising a subsea housing assembly according to the present invention and further comprising a sensor element disposed in the first housing portion, wherein the first electrical connection is configured for providing communication with the sensor element, and wherein the second electrical connection is configured to provide at least a sensor output of the subsea sensor.
  • a data communication can be established through the wall of the subsea housing without using conventional glass penetrators which require a glass to metal sealing and need to be tested at 2.5 times the operating pressure, requiring the entire sensor to be designed to reliably withstand 2.5 times the operating pressure.
  • an inductive coupler it should be possible to test at only 1.5 times the operating pressure thereby reducing the design and testing requirements considerably. Additionally, problems associated the manufacture of glass to metal junctions and reduced insulation resistance of such penetrators may be avoided.
  • a single electrical line may be provided for power supply and data communication, for example by providing a respective modulation on the power line.
  • separate lines may be provided and may be part of the respective electrical connection, for example dedicated lines for power supply and data communication.
  • the sensor may only be a passive sensor, and only the electrical power required to read such passive sensor may be transmitted by means of the inductive coupler.
  • further electric and/or electronic components may be provided in the first housing portion, for example for operating the sensor element or processing sensor data.
  • the inductive coupler's first and second coupling sections preferably provide inductive coupling for both data communication and power transfer.
  • the inductive coupler may comprise further coupling sections, for example for separately transferring electrical power and communication signals.
  • the first housing portion may for example comprise a sensor assembly including diaphragms, such as a process diaphragm and a sensor diaphragm, a sensor element, medium filled channels or the like and may further include a first pressure barrier that provides separation between the pressure prevailing in such medium filled channels and the first chamber.
  • a process diaphragm may transmit the pressure of the process fluid to such medium (e.g. oil) present in the channels, which in turn applies the pressure to a sensor element. Accordingly, if such first pressure barrier fails and process fluid or process fluid pressure is transmitted into the first chamber, such fluid/pressure can be confined to within the first housing portion by means of the wall which constitutes a second pressure barrier.
  • the first housing portion may be sealed against a metal body by means of a metal seal, in particular a metal gasket.
  • the subsea housing assembly may be part of a subsea sensor, and the first housing portion may be sealed against a pipe section, for example a pipeline section or a flow duct in a Christmas tree or the like.
  • the first housing portion may comprise a mounting flange for mounting the subsea housing assembly to such metal body.

  • the first housing body 12 substantially surrounds the first chamber 11.
  • the first housing portion 10 includes a wall 30 that provides a pressure barrier. This allows application of a high pressure difference across the walls of the first housing body 12.
  • the wall 30 provides separation between the first chamber 11 and the second chamber 21. Accordingly, a safe and reliable sealing can be provided between the first and second chambers 11, 21 that is capable of withstanding high pressure differences, for example in excess of 1,000 or even 2,000 bar.
  • the first housing portion 10 may simply be closed, for example by means of a closing plate or the like.

  • the subsea housing assembly 100 is used for a subsea sensor 200 and a first pressure barrier 17 is provided in the first housing portion 10.
  • the first pressure barrier 17 provides sealing of the first chamber 11 towards a part of the first housing portion 10 in which a sensor element 61 is located and exposed to high pressures, such as the high pressure of a process fluid.
  • such exposure may be a direct exposure, or an indirect exposure, for example via a respective process diaphragm and a pressure transmission fluid such as oil or the like.
  • the first chamber 11 may comprise sensor electronics 62, such as control electronics, data processing electronics and the like.
  • the first chamber 11 may be a pressure resistant chamber in which a predefined pressure is maintained, even when the subsea housing assembly 100 is installed at a subsea location.

  • first pressure barrier 17 may for example comprise a feed through for an electric connection to the sensor element 61, or the sensor element 61 may itself be configured so as to constitute a pressure barrier.
