Definitions

  • the present invention relates to a connector (also referred to as a pin-to-pin adapter or CMI gland) for electrically connecting two pins in a subsea environment, further relates to a connector system and still further relates to a method for electrically connecting two pins in a subsea environment.
  • a connector also referred to as a pin-to-pin adapter or CMI gland
  • an adapter in particular pin-to-pin adapter, also referred to as connector or common module interface (CMI), may be required.
  • CMI common module interface
  • the adapter may be used for directly joining two front ends. Due to unknown lengths within each assembly (in particular due to unknown pin lengths) (unknown machine lengths, temperature variations, etc.), the contact pins in the gland must be positioned so that the two assemblies can be fully brought together for all material conditions. This may necessitate that there is a void between the two front ends (in particular the two electrical pins) during normal assembly and operation so that the worst cases can be accounted for.
  • this void or gap may be that the contact region may require a stress control termination moulding across the pins to control how the electric field transfers from one assembly to the next.
  • This moulding may be elastomeric so that it is not able to resist the pressure forces from the hydrostatic pressure at high depths in the sea without being fully supported. Therefore, the stress control termination moulding may extrude into and may be damaged by any gaps or voids in the support structure. This may create a problem in that the dry-mate may require a gap to ensure that assembly can occur whereas the stress control termination moulding (which may be a key enabler for the dry-mate) cannot accommodate any gaps at all.
  • WO 2016/146667 A2 discloses a conductor assembly with two conductive core parts, in particular a first conductive core part and at least a second conductive core part, wherein the first conductive core part is axially movably arranged in respect to the at least one second conductive core part, wherein an insulating sleeve is provided that is axially movably arranged in respect to the first conductive core part and the second conductive core part wherein at least one loading arrangement is embodied in such a way so that the first conductive core part is loaded in an axial direction against the at least one second conductive core part. Due to the loading, an insulating sleeve is clamped between the first conductive core part and the second conductive core part.
  • EP1381117 discloses a connector according to the preamble of claim 1.
  • front ends including the pins
  • the front ends may be subject to high load during typical subsea applications for example at hydrostatic pressures between 300 bar and 500 bar.
  • a connector for electrically connecting two pins in a subsea environment there may be a need for a connector system and there may be a need for a method for electrically connecting two pins in a subsea environment, wherein a reliable electrical connection of two electrical pins may be achieved while preventing high load on the pin equipment and avoiding (or at least reducing) damage of components, in particular front ends including electrical pins.
  • a connector (also referred to as pin to pin adapter or common module interface (CMI) gland) for electrically connecting two pins in a subsea environment
  • the connector comprising: a conductive sleeve for sliding in the two pins from opposite sides and for electrically contacting the two pins with each other; for each pin, a rubber ring surrounding a portion of the respective pin axially outside the conductive sleeve; an elastomer moulding surrounding the conductive sleeve and the two rubber rings; a casing providing an internal space fillable with oil, a diaphragm in a wall of the casing allowing compensation of the pressure in the internal space with an outside pressure, wherein the elastomer moulding, the rubber rings and the conductive sleeve are located within the internal space, wherein the rubber rings are configured to at least partly transmit a pressure applied to the elastomer moulding towards radially inwards.
  • CMI common module interface
  • the connector is configured to electrically connect two pins under high hydrostatic pressure such as between 300 bar and 500 bar, for example for subsea operations or explorations.
  • the pin may be made from a conductive material, such as copper or a copper alloy.
  • the conductive sleeve may in particular have an essentially cylindrical shape having a slightly larger inner diameter than an outer diameter of the pins to be connected. The two pins may be slid into the conductive sleeve from opposite ends.
  • the rubber ring may surround a portion of the pin where the pin is free of an insulating layer, such as an insulating plastic cladding or cover.
  • the rubber ring may transmit a force exerted from the elastomer moulding axially towards the end of the respective pin (and also, in particular, radially inwards). Thereby, pressure forces may be transmitted using the rubber ring axially towards the pin. Thereby, a pressure differential across the connector (in particular in the mated state having connected thereto a first pin from a first side and a second pin from the second side) may be reduced.
  • Both the rubber ring as well as the elastomer moulding may be elastic, flexible materials which may deform under hydrostatic pressure which may essentially reside within the internal space due to the pressure compensation via the diaphragm.
  • the connector may substantially have a cylindrical shape.
  • the diaphragm may be flexible/deformable but may be sealed tight against water and oil which may be present within the internal space. Oil may be present surrounding (at least a portion) of a radially outer surface of the elastomer moulding. As an outside hydrostatic pressure increases, the outside pressure may be transmitted via the diaphragm to the internal space such that the oil may act on the elastomer moulding, thereby compressing the elastomer moulding.
  • An inner surface of the elastomer moulding (at least a portion thereof) may be in contact with an outer radial surface of the rubber ring (at least in a mated state wherein a pin is inserted through the respective rubber ring) such that the pressure force acting on the elastomer moulding may be (at least partly) transmitted to or towards the rubber ring, in particular in a radial direction or in all different directions. Thereby, pressure equilibration may be promoted, at least reducing a pressure differential within the connector.
  • the connector further comprises for each rubber ring, a pair of supporting rings (also referred to as anti-extrusion rings), in particular sandwiching the respective rubber ring, the pair of supporting rings being arranged to support the respective rubber ring to at least reduce or even prevent extrusion when subjected to high pressure.
  • a pair of supporting rings also referred to as anti-extrusion rings
  • the supporting rings may be contacting each rubber ring from both axial sides.
  • the supporting rings may be slightly deformable but may be not as soft as the respective rubber ring.
  • the supporting rings may be configured not to extrude into any gaps or voids around them, even under high pressure.
  • the rubber ring may be relatively soft such that the rubber ring easily deforms under high pressure which may have, without the pair of supporting rings, the risk to extrude into a gap or void surrounding the rubber ring.
  • the supporting rings may be made of or may comprise polytetrafluoroethylen (PTFE, Teflon) or a similar material which has similar mechanical properties as PTFE.
  • PTFE polytetrafluoroethylen
  • Both, the rubber ring as well as the supporting ring, may be made of electrically insulating material. Electrically insulating material may, however, not be required as the inner layer of the stress control moulding may create a shielded chamber and so there may be no electrical stress in the region of the rubber/PTFE rings.
  • the rubber ring as well as the supporting ring may be made of electrically conducting material.
  • a first supporting ring is between a respective axial end of the conductive sleeve and one axial end of the respective rubber ring and a second supporting ring is between another axial end of the respective rubber ring and a plastic sleeve of the respective pin.
  • the plastic sleeve may be made of an electrically insulating material.
  • the plastic sleeve of the respective pin may press in the axial direction onto the rubber ring, in response to which the rubber ring may deform and may bulge out in the radial direction to contact the radially inner surface of the elastomer moulding. Thereby, a pressure transmission from the elastomer moulding towards the rubber ring and from there to other surrounding elements is enabled.
  • the supporting rings essentially completely fill a radial space between the pin and the elastomeric moulding axially external to the rubber rings, in particular also in the demated state.
  • the supporting rings When the supporting rings essentially completely fill a radial space between the pin and the elastomer moulding, they may form an effective barrier for the rubber ring to prevent extrusion of portions of the rubber ring into any surrounding voids or gaps.
  • the sandwiching supporting rings may confine the rubber rings in a space axially between the pair of supporting rings.
  • At least one supporting ring of each pair of supporting rings has a small pin or point, which may push/insert into a portion of the respective rubber ring, in particular when pressed together in a state mated with a pin, to hold the rubber ring in place.
  • the rubber ring may be hold in place, in particular in the mated state, in which a pin is guided through the rubber ring to be electrically contacted within the conductive sleeve.
  • the rubber ring at atmospheric pressure and/or in a demated state, has a smaller radial extension than the elastomeric moulding (and the conductive sleeve), such that a radial void is present between a radial outer surface of the rubber ring and the elastomeric moulding, wherein the rubber ring has in particular a rectangular cross-sectional shape.
  • the single-demated state is a state of the connector in which only one pin is connected to the connector. In the completely demated state, not any pin is connected to the connector. In the single-mated state, one pin is connected to the connector, in the completely mated state, two pins are connected to the connector from opposite sides. In the mated state a pin is contacting the conductive sleeve at the side of the connector under consideration. In the demated state no pin is present in the conductive sleeve at the side of the connector under consideration.
  • the rubber ring bulges out such that the radial void is filled and the radial outer surface of the rubber ring touches and presses/pushes against the elastomeric moulding, thereby allowing the elastomeric moulding to transmit a pressure force to the rubber ring which may create a hydrostatic, compensating force on all surfaces it comes in contact with.
  • the radial void is filled with the material of the deformed rubber ring, an effective contact to the elastomeric moulding is achieved, such as to enable a pressure transmission.
  • the elastomer moulding comprises a conductive layer at a radial inner face thereof, the conductive layer surrounding the conductive sleeve, the rubber rings, the pairs of supporting rings and a portion of the pins axially outside the rubber rings and the supporting rings, in particular further surrounding a portion of a plastic sleeve of the pins.
  • the conductive layer at the radial inner face of the elastomer moulding may effectively form a Faraday cage in order to provide an electrical shielding.
  • the electrostatic potential of the conductive layer at the radial inner face may be substantially at earth potential. Thereby, an electrostatic field which may be present surrounding the pins may be shielded by the conductive layer at the radial inner face of the elastomer moulding.
  • the conductive layer may also be elastic and may deform similar to the other material of the elastomer moulding.
  • the elastomer moulding may further comprise, at a radial outer face, also another conductive layer for providing a shielding effect.
  • the conductive sleeve comprises, at an inner face, at least two axially spaced apart electrical contact areas, each in particular comprising multilams, the conductive sleeve in particular made of copper or an copper alloy.
  • the electrical contact areas may be made of resilient material providing a force towards radially inwards for ensuring a reliable electrical contact.
  • the conductive sleeve essentially has a cylindrical shape having a single inner diameter for accommodating both pins.
  • the conductive sleeve may comprise a first axial portion and a second axial portion having different inner diameters for accommodating pins having different outer diameters.
  • the rubber rings are soft so that they move/deform at forces much lower than the applied pressure force and are the rubber rings are incompressible. Incompressible means that the volume of the rubber ring will not change as the hydrostatic pressure forces are applied. This is essential as if the material was compressible its volume would reduce under hydrostatic pressure and thereby allow the stress control moulding to extrude into the space.
  • the rubber rings effectively may act as pressure transmitters from the internal space towards other components surrounding the rubber rings.

  • Further seals 165 are provided for sealing the plastic cladding 161 with the core 159.
  • the depth pressure is allowed to act on part of the end face of the front ends in the gland, i.e. the crimp is part compensated to reduce (not remove) the differential pressure force to a level which is easier to manage in the design of the front ends.
  • this may be achieved by replacing part of the conventionally provided metal ring with a soft rubber ring (the one used according to an example application has 15 Shore hardness).
  • the exact composition of the ring is not important, it just needs to be relatively soft so that it moves/deforms at forces much lower than the applied pressure force and the ring should be incompressible.
  • the soft rubber ring may be kept into place by an anti-extrusion ring (also referred to as supporting rings) on either side: one of which interfaces with the metal work used to make the contact and the other interfaces with the end of the pin.
  • anti-extrusion ring also referred to as supporting rings
  • These PTFE rings are to ensure that the soft rubber ring and the stress control termination moulding (also referred to as elastomeric moulding) cannot extrude into any gaps or voids.
  • These PTFE rings may have a slight point in them. The purpose of this point is to "grab" the rubber ring during its compression to ensure that it cannot extrude straight out of the top of the groove in which it sits.
  • the soft rubber ring may be compressed so that it may bulge outwards, pushing on the inside of the stress control termination moulding. Once the pressure is applied to the outside of the stress control termination moulding, it can then transmit the force to the soft rubber ring which may create a hydrostatic, compensating force on all of the surfaces it comes into contact with. According to an embodiment of the present invention, thereby, the area which is not pressure compensated is reduced from 60 mm diameter to a 40 mm diameter which may reduce the differential pressure force by 55%.
  • the part compensated crimp may reduce the pressure loading to a level which is acceptable to the current design.
  • the soft rubber ring (at each side of the connector) may be in contact with the inside of the stress control termination moulding which may allow pressure to be transmitted down to smaller diameters. This may reduce differential pressure forces acting on the front ends whilst still preventing the creation of any extrusion gaps which would damage the stress control termination moulding. This is achieved without the need to gauge lengths, to perform liquid fills and allows the front end to be terminated and pressure cycled multiple times without having to refurbish the gland.
  • the use of the soft rubber rings fills the variable length gaps between assembly, transmits pressure axially and thereby performs pressure compensation, and the use of anti-extrusion rings may hold the soft rubber ring and prevent it from extruding into other locations. Using embodiments of the present invention enable dry-mate technology to be performed.
