Definitions

  • the present invention relates to an engagement mechanism for couplings to be operated by remotely operated vehicles (ROVs), particularly mono-couplings, which couplings may be used to connect tube and hoses on the seabed, such as hydraulic or pneumatic lines, to fixed structures, these lines can be used to transfer power or to inject a fluid or gas at a well head, for example.
  • ROVs remotely operated vehicles
  • mono-couplings which couplings may be used to connect tube and hoses on the seabed, such as hydraulic or pneumatic lines, to fixed structures, these lines can be used to transfer power or to inject a fluid or gas at a well head, for example.
  • Present coupling normally comprise two parts.
  • a fixed part arranged to be attached to a fixed structure on the seabed, such as to a distribution manifold or to a Christmas tree mounted to a wellhead, with the second part of the coupling, the “flying” part, being attached to the end of a hydraulic or pneumatic line.
  • both ends of a pressure hose, or section of metal tubing will terminate at a respective flying part of a mono-coupling, with the two flying parts and intervening hose, metallic tubing or similar, forming what is termed a single line jumper (or single line hydraulic flying lead).
  • ROV mono-coupling manufactured by MSCM Limited. This comprises two parts as described above, wherein the fixed part comprises a port into which the flying part of the coupling is inserted in an axial direction. The fixed part providing a bayonet coupling such that the flying part can be pushed into the port by the ROV in an axial direction and then rotated by the ROV about its axis through 90°.
  • the action of rotation of the flying part initially engages pins on the flying part with ramps of the bayonet coupling on the fixed part, such that the flying part can no longer be axially withdrawn from the fixed part.
  • Continued rotation of the flying part in the fixed part then causes the ramps of the bayonet coupling to urge the pins on the flying part forward in the axial direction as they rotate, drawing the two parts of the coupling together and establishing a hydraulic or pneumatic connection between the two parts of the coupling, against the force exerted by the supply pressure that may be present.
  • a problem that can arise with the current coupling is that if two fly couplings are used to terminate respective ends of a relatively stiff hose, pipe or a tube, then once the first coupling has been made at a first end, rotating the second fly coupling at the other end, to make the second coupling, can act to undo the first coupling.
  • an engagement mechanism for a remotely operated vehicle (ROV) mono-coupling which engagement mechanism is arranged to be operated by an ROV and to receive and house two halves of a coupling, to form an ROV mono-coupling.
  • ROV remotely operated vehicle
  • the engagement mechanism comprising: a fixed part arranged to be connected to a fixed structure and to house a first half of the coupling; and a flying part, arranged to be connected to a hose, tube or pipe and to house a second half of the coupling, wherein: the fixed part of the engagement mechanism comprises a port in which the flying part may be docked in an axial direction; the flying part of the engagement mechanism comprises a rotatable handle to be rotated by an ROV; the flying part of the engagement mechanism comprises a threaded member rotated by the rotatable handle, and wherein, once the flying part of the engagement mechanism has been docked in the port of the fixed part, rotation of the rotatable handle by the ROV in a first direction causes the threaded member to first lock the flying part axially in the fixed part, with continued rotation of the threaded member in the first direction subsequently causing a second half of the coupling housed in the flying part of the engagement mechanism to establish a connection with the first half of a coupling house
  • An engagement mechanism in accordance with the present invention provides the mechanical advantage offered by a screw thread, to both lock two parts of the engagement mechanism axially together and subsequently advance the second half of a coupling into connection with each other half, without the need to employ a direct conventional screw threaded coupling.
  • the single action of rotating the rotatable handle in a single direction causes the flying part to first lock itself into the port of the fixed part before connecting the two halves of the coupling housed within the engagement mechanism.
  • the screw threaded action can provide sufficient force to connect relatively large sizes of coupling together, where one may for example be at a live operating pressure of 15,000 psi (100,000 kPa), with no rotational forces being placed on a hose tube or pipe extending from the flying part.
  • An engagement mechanism in accordance with the present invention may typically be used to connect a 3/4 inch (1 .9 cm) coupling having a live design pressure of 15,000 psi (100,000 kPa), or to connect a non-pressurised coupling to subsequently operate at a design pressure of 22,500 psi (160,000 kPa).
  • a further advantage of the present invention is that it permits a coupling to be used which is separate to the engagement mechanism used to connect the two halves of the coupling together. This enables a faulty damaged or worn coupling to be replaced without the need to replace the engagement mechanism. It may also permit different types of couplings to be used, so that the engagement mechanism need not be specific to one application or to one specific brand of coupling.
  • the flying part is arranged to be inserted axially into the port to a predetermined position, prior to the rotatable handle being rotated by the ROV to lock the flying part in the fixed part.
  • the ROV can first dock the flying part of the engagement mechanism with the fixed part, by first generally aligning the flying part with the port of the fixed part and pushing the flying part into the port, prior to engaging with commences rotation of the rotatable handle.
  • a visual indicator is provided to indicate to the ROV operator when the flying part has been fully inserted into the fixed part to the predetermined position.
  • the flying part may comprise a main body having an engagement surface arranged to contact an engagement surface of a main body of the fixed part, to form a stop and limit insertion of the main body of the flying part into the main body of the fixed part. This stop will ensure that the flying part can not be overly inserted, which could otherwise cause damage to a coupling housed therein.
  • the main body of the of the flying part is prevented from rotating in the main body of the fixed part. This ensures that the action of rotating the rotatable handle does not act to rotate the flying part, for this would act to rotate any hose tube or pipe connected to the flying part.
  • the flying part comprises a carrier for the second half of the coupling, the carrier being threaded onto the threaded shaft, which carrier can move axially forward on the shaft as the shaft is rotated in a first axial direction and backwards on the shaft as the shaft is rotated in a second axial direction opposite to the first direction, wherein rotation of the handle in the first direction causes the carrier to move forward urging a locking device in the main body of the flying part to be displaced radially outward from the main body of the flying part, to engage with the main body of the fixed part, to lock the two parts together in the axial direction, prior to continued rotation of the handle and continued forward movement of the carrier pushing the second half of the coupling into engagement with the first half of the coupling.
  • the action of rotating the screw thread can thus initially place significant force on the locking device ensuring correct and positive operation of the locking device, prior to that same screw thread exerting a significant force, in an axial direction, on the second half of the coupling, to ensure positive engagement of the two haves of the coupling against any resistance provided by appropriate seals and to open a connection between the two halves of the coupling, one or more of which may be connected to a pressurised supply of fluid.
  • the carrier may have one or more cammed surfaces wherein the locking device comprises one or more dogs which may extend through apertures in a main body of the flying part to engage with the fixed part, wherein, as the carrier first moves axially forward, the one or more cammed surfaces act to push the one or more dogs radially outward so that they extend through the apertures in the main body and engage with the fixed part and wherein the one or more dogs are retained in the extended outward position by a surface or surfaces of the carrier during the continued forward movement of the carrier.
  • the locking device comprises one or more dogs which may extend through apertures in a main body of the flying part to engage with the fixed part, wherein, as the carrier first moves axially forward, the one or more cammed surfaces act to push the one or more dogs radially outward so that they extend through the apertures in the main body and engage with the fixed part and wherein the one or more dogs are retained in the extended outward position by a surface or surfaces of the carrier during the continued forward movement of the carrier.
  • the above arrangement permits the initial rotation of the rotatable handle to cause the dogs to be pushed outward and then causes them to be held in the outward “locked” position by the surface or surfaces of the carrier, as the carrier continues to moves forward to engage the two halves of the coupling.
  • the engagement mechanism may additionally further comprise biasing means which acts to retain the flying part of the engagement mechanism docked in the port of the fixed part, prior to the flying part being locked in the fixed part.
  • the biasing means may be in the form the visual indicator provided to indicate to the ROV operator when the flying part has been fully inserted into the fixed part to the predetermined position, for this may be spring biased inwardly through a main body of the fixed part to engage with a groove of recess on the flying part.
  • the flying part comprises a mounting for the second half of the coupler, which mounting is secured to the carrier and is interchangeable depending on the type of coupling housed in the engagement mechanism.
  • the fixed part also comprises a mounting for the first half of the coupler, which is interchangeable depending on the type of coupling housed in the engagement mechanism. This permits different types of coupling to be used with the engagement mechanism.
  • This above arrangement also enables new designs of mountings to be designed and fitted to the engagement mechanism, to accommodate new designs of couplings, avoiding the time and expense of designing a new engagement mechanism
  • the mounting for the second half of the coupler comprises an engagement surface arranged to contact an engagement surface of the main body of the fixed part, to form a second stop that limits further forward travel of the mounting for the second half of the coupler. This prevents over insertion of the first half of a coupling into the second half of the coupling which could damage the coupling.
  • the interchangeable mounting for the second part of the coupling forms part of the stop, the mounting may be designed to restrict forward travel to a position appropriate for the type of coupling it is intended to be used with.
  • the engagement mechanism comprises a visual indicator to indicate when the mounting for the second half of the coupler has reached the second stop.
  • the indicator will confirm to an ROV operator that two halves of the connector should be fully inserted and a connection established, with the point at which the indicator is set being dependent on the mounting employed, so that this may be tailored to a specific coupling type.
  • the engagement mechanism may further comprise a resilient nose cone on the front of the mounting for the second half of the coupler, which nose cone surrounds a second half of the coupler. This may act to shield the second part of a coupler from damage and aid insertion of the flying part into the fixed part and also avoid damage during the process of insertion.
  • the engagement mechanism as described above is particularly applicable for use in remotely connecting a subsea hose, tube or pipe to a fixed structure on the seabed.
  • the engagement mechanism is preferably arranged such that once a connection has been established between two halves of a coupling, subsequent rotation of the rotatable handle by an ROV in a second direction, opposite to the first direction, causes the second half the coupling, housed in the flying part, to withdraw from the first part of the coupling, housed in the fixed part of the engagement mechanism, and to subsequently cause the threaded member to unlock the flying part from the fixed part to permit the flying part to be axially withdrawn from the fixed part.
  • an ROV mono-coupling comprising an engagement mechanism as described above and a coupling, wherein the second half of the coupling, housed in the flying part of the engagement mechanism, has a connector for a hose, tube or pipe, which connector extends in a direction having a radial component out of a hole or slot in a main body of the flying part and wherein a main body of the fixed part has an open ended slot extending axially to a distal end of the main body, which slot is arranged to receive the connector as the flying part is received into the fixed part.

  • This action of the spring 19 also acts to maintain the flying part 3 in the fully docked position, which is important because in this position the ROV will normally release the manoeuvring handle 6 to engage with the rotatable handle and thus the spring prevents the flying part being accidentally dislodged at this stage.

This indicates to the ROV operator that the flying part 3 is fully inserted. This can be doubled checked by at the same time noting that the second indicator 18 is partly raised. Only in the docked position shown in Figure 8 can the two indicators 17 and 18 have this configuration.
  • Movement of the cam member 28 forward in an axial direction to the position shown in Figure 10 also moves the female coupling mount 33 and female coupling 23 forward in the axial direction, together with the with chamfer 41 , most clearly visible in Figure 3.
  • the forward movement of the chamfer 41 raises the second indicator 18 to a maximum position, seen in Figure 10, where two coloured bands are visible to the ROV operator, indicating that the female coupling mount 33 is about to reach the limit of its forward travel.
