Description

1 / 17 “ORIENTATION PIN” FIELD OF DISSEMINATION

[0001] This disclosure relates to a guide pin for subsea well equipment, a blowout preventer, BOP, comprising the guide pin, a system for guiding a pipe hanger within a well blowout preventer and for providing communication, and a method for communicating between, on the one hand, an exterior of a BOP and, on the other hand, a pipe hanger guide joint or other equipment within the well. FUNDAMENTALS

[0002] The primary function of a BOP is to provide a critical safety barrier during drilling and well control operations. BOPs are installed at the wellhead and are designed to control wellbore pressure, prevent uncontrolled blast releases, and maintain well integrity.

[0003] To ensure proper orientation, the BOP used at the wellhead is equipped with a guide pin, such as a BOP orientation pin or a guide pin. The guide pin is typically connected and integrated into the BOP equipment, and its main function is to ensure the correct alignment and positioning of various components within the BOP. Specifically, the guide pin's purpose is to guide a pipe hanger through the pipe hanger's guide joint.

[0004] Subsea oil and gas umbilicals are specialized cables used to transport fluids and electrical power to and from subsea production systems. These umbilicals, which can be made of various materials such as steel, plastic, or composite fibers, typically include a combination of fluid lines, electrical conductors, and control lines. They are used in offshore oil and gas production to connect subsea production systems, such as wells and manifolds, to surface production facilities.

[0005] A pipe hanger installation, known as a pipe hanger installation process within a wellhead or a Petition 870260059124, dated 06 / 17 / 2026, page 10 / 36 2 / 17 Wellhead Assembly. The tubing hanger is a component used in the oil and gas industry to suspend and seal production tubing within the wellbore, allowing for the safe and controlled production of fluid from the reservoir to the surface. Installing a tubing hanger is a step in well completion. Currently, traditional tubing hanger installation is an expensive operation from both a CAPEX and OPEX perspective. A significant portion of this cost comes from the umbilical hardware and the time required to operate the subsea umbilical, i.e., the time spent at sea. Communication refers to the usual communication between the bottom of the well and the topside, which typically occurs through the umbilical in the tubing string.

[0006] A known technical problem associated with BOPs is how to communicate from outside the BOP to something inside the BOP. Another technical problem is that any communication must function without the possibility of failure, meet technical and legal requirements, and be easy to use. It is desirable that any solution be simple, inexpensive to produce, and reliable. It is also a technical problem to avoid cumbersome arrangements that are expensive to manufacture or assemble.

[0019] Figures 1 and 2 are diagrammatic and schematic illustrations of a subsea well rig on the seabed showing a BOP 200 at the top of the well. The seabed and any downhole equipment are not illustrated for clarity. Figure 1 also illustrates a Remotely Operated Vehicle 500, ROV, which can operate at least part of the BOP and the guide pin. Figure 3 is a diagrammatic and schematic illustration of a more detailed cutaway view along the guide pin axis of a part of the BOP 200 with a part of a pipe suspension guide joint 300, THOJ, inside the BOP.

[0020] Figure 1 illustrates a 100 orientation pin for subsea well equipment, which is configured to provide guidance and communication. In the prior art, the orientation pin only ensures alignment and positioning. Petition 870260059124, dated 06 / 17 / 2026, page 14 / 36 6 / 17 correct of a 300 pipe hanger orientation joint, THOJ, inside the BOP 200. However, according to the present disclosure, orientation pin 100 is not only configured for orientation but is also configured for communication. Preferably, communication can be done through orientation pin 100 once orientation pin 100 has been used for orientation. Communication can be information communication, for example, data transfer of information such as command instructions, sensor data, etc. This allows communication through orientation pin 100 from, on the one hand, an exterior of a BOP 200 and, on the other hand, an interior of the BOP 200.

[0021] Guidance pin 100 is configured to provide guidance and communication. Guidance and communication can be performed simultaneously, or one before the other, or one starting first and the other starting before the first finishes. Guidance can be any one, or a combination, of the following: stopping a submersible element; rotating a submersible element; and positioning a submersible element in a predetermined position. Guidance can be done by physical contact, for example, guiding, stopping, restraining, etc. The submersible element can be a THOJ 300. Communication can be any one, or a combination, of the following: data communication / transfer; an electrical connection; electron flow; energy; and transport of a fluid, for example, a hydraulic fluid and / or a fluid comprising chemicals.In addition to the guidance provided by orientation pin 100, the communication provided by orientation pin 100 may include energy, for example, electrical energy or hydraulic energy. The communication may pass through orientation pin 100, for example, through the interior of orientation pin 100.

[0022] The orientation pin 100 can first be used to orient a subsea element, such as a bedding column, preferably a THOJ 300, within the BOP 200. When the orientation pin 100 has reached its final position, for example, on an alignment plate or a slot, the orientation pin 100 can be located in a data communication position, for example, making an electrical connection and / or an inductive coupling to Petition 870260059124, dated 06 / 17 / 2026, page 15 / 36 7 / 17 Transfer data. Data communication can be high-speed communication. Communication can be riser communication and comprise one or more of the following: an electrical connector, an inductive connector. The inductive connector can be a pinless connector. Communication can be electrical signals through the electrical connection and / or communication can be electromagnetic induction through inductive coupling. Communication can be high-speed data communication, for example, a communication speed higher than a communication speed passing through an umbilical.

[0023] Data communication in open water, for example, from guidance pin 100 to the upper side, may be different from data communication through guidance pin 100. Data communication in open water may be one or more of the following: radio signals, light, ultrasound, and high-frequency signals. This is not communication between guidance pin 100 and the THOJ 300; instead, this is communication that goes from guidance pin 100 to one or more of: an upper side, a subsea station, a remotely operated vehicle, ROV, or BOP umbilical. This is communication outside the column, outside the BOP 200 in open water.

[0024] The 100 guide pin can be configured to be disposed in a 200 subsea element. The 200 subsea element can be a 200 blowout preventer, a 200 BOP, or a reel piece. The 200 subsea element can be part of a subsea well rig. As best illustrated in Figure 3, the 100 guide pin can reach through the 200 BOP and project inward and make contact with a 300 THOJ. However, in an inverted version of the 100 guide pin, the 200 subsea element can be one of a settling string, a hanger, or a pipe hanger guide joint.

[0025] The 100 orientation pin can be used and configured for more than just orientation and communication. According to one embodiment, the 100 orientation pin can also be configured to transport a fluid, preferably a hydraulic fluid and / or a liquid chemical. This allows fluid communication from, on the one hand, the exterior of a BOP 200 and, on the other hand, the interior. Petition 870260059124, dated 06 / 17 / 2026, page 16 / 36 8 / 17 of BOP 200. Fluid connectors can make fluid connections through, for example, an axial movement of the guide pin 100. For example, the guide pin 100 may comprise a fluid connector at its axial end or ends or along an exterior between the ends of the guide pin 100. The axial movement of the guide pin 100 may open or close one or more fluid connectors. For example, the guide pin 100 may comprise an internal fluid conduit 110 along its axial direction. In Figure 3, transmitters / receivers were illustrated by items 410 and 420, but these items 410 and 420 may also illustrate an example where connectors for fluid communication may be arranged in addition to transmitters and receivers.

[0026] The orientation pin 100 can also charge batteries stored in the THOJ 300 or another special joint above the BOP 200. The orientation pin 100 can also power a motor, or a tool or equipment, in the THOJ 300 or connected via the THOJ 300 or another special joint above the BOP 200. The orientation pin 100 can be configured for this, in addition to providing data communication, for example, sending and receiving signals to control functions within the THOJ 300 or another special joint above the BOP. The orientation pin 100 can be configured to provide communication and electrical power between, on the one hand, an exterior of a BOP 200 and, on the other hand, an interior of the BOP 200.

[0027] According to one embodiment, communication via guidance pin 100 may be data transfer between, on the one hand, one or more of: an upper side, a subsea station, a remotely operated vehicle, ROV or BOP umbilical and, on the other hand, one or more of: downhole equipment, a control module and / or other equipment on a hanger or string, downhole sensor and meter. The communication may be data information transfer, for example, data information such as command instructions, sensor data, etc. The communication may be high-speed data communication, for example, a communication speed higher than the communication speed passing through an umbilical. The communication speed in an umbilical may be, for example, 50 Mbps or less. This Petition 870260059124, dated 06 / 17 / 2026, p. 17 / 36 The 9 / 17 enables communication from an upper side, such as an offshore platform, or from a subsea station, via the BOP 200 and the 100 guide pin to the downhole equipment and back. Communication is therefore between, on one side, the exterior of a BOP 200 and, on the other side, the interior of a BOP 200, and there is no need for an umbilical or communication line within the piping to the sea surface. This also allows various operations to be performed when installing the THOJ 300, since data communication for downhole operations is immediately available.

[0028] The orientation pin 100 can comprise a transmitter / receiver for communication. The THOJ 300 can comprise a transmitter / receiver for communication. In Figure 3, transmitters and receivers are illustrated by items 410 and 420. Transmitters / receivers 410 and 420 are components used for communication that allow real-time communication, such as monitoring, control, and data collection, contributing to the safe and efficient operation of well equipment. Components 410 and 420 can transmit and receive data. Data communication can include data from sensors that measure parameters such as temperature, pressure, flow rates, and fluid levels of the well equipment. The data collected by these sensors can be transmitted through orientation pin 100. Transmitters / receivers 410 and 420 for communication can be located one on orientation pin 100 and one on subsea element 200, as illustrated in Figures 1 and 3.A 410 transmitter / receiver can be placed on orientation pin 100, and a 420 transmitter / receiver can be placed inside the THOJ 300. An axial movement of orientation pin 100 towards the THOJ 300 can make the connection for communication through the 410 and 420 transmitters / receivers.

[0029] According to one embodiment, the orientation pin 100 may comprise an electrical connection and / or an inductive coupling configured for communication. In Figure 3, transmitters / receivers have been illustrated by items 410 and 420, but these items 410 and 420 may also illustrate an example where the electrical connection and / or the inductive coupling may be arranged. The coupling Petition 870260059124, dated 06 / 17 / 2026, page 18 / 36 10 / 17 electrical coupling can be, for example, two pins to be received in two openings, for example, a plug and a socket. Inductive coupling can be two conductors configured in such a way that a change in current through a wire of one conductor induces a voltage across the ends of another wire of the other conductor through electromagnetic induction. An axial movement of the orientation pin 100 towards THOJ 300 can make the connection for communication through electrical connection and / or inductive coupling.

[0030] Depending on the embodiment, communication may be one or more of the following: radio signals, light, ultrasound, and high-frequency signals. For example, a wireless communication arrangement allows for flexible alignment of the 410 and 420 transmitters / receivers of the 100 orientation pin and the 200 subsea element, for example, a THOJ 300. This arrangement provides reliable and resilient data communication, even under extreme environmental conditions. Communication being one or more of the radio, light, ultrasound, and high-frequency signals provides secure data communication and personnel safety, is reliable and precisely timed even under extreme conditions below the surface. Communication via orientation pin 100 can occur when the BOP 200 and orientation pin 100 are subsea in the open sea with the 300 pipe hanger orientation joint oriented and aligned within the BOP 200.

[0031] According to one embodiment, the orientation pin 100 can be configured to guide a pipe hanger orientation joint 300, THOJ, in a subsea well, and the orientation pin 100 can be configured to provide communication between a subsea well topside and downhole equipment. Normally, communication between downhole equipment and the subsea well topside occurs through an umbilical in the string. However, the embodiments described in this document allow communication through the orientation pin 100, thus without an umbilical in the string.

[0032] As best illustrated in Figure 1, a 500 ROV with its own 510 umbilical can be used to operate and / or communicate with well equipment via the 100 guidance pin. The 500 ROV can be controlled from one side Petition 870260059124, dated 06 / 17 / 2026, p. 19 / 36 11 / 17 upper via the ROV 510 umbilical. The ROV can connect and operate guidance pin 100. In this way, for example, an upper side can communicate via the ROV 510 umbilical and ROV 500, via guidance pin 100, with the underwater element, for example, the THOJ 200.

[0033] According to one embodiment, as illustrated in Figures 1 to 3, a blowout preventer 200, BOP, comprises the orientation pin 100, according to any of the embodiments described in this document. When the orientation pin 100 is disposed in the BOP 200, the orientation pin 100 can orient the THOJ 300 and provide communication between, on the one hand, an exterior of the BOP 200 and, on the other hand, the THOJ 300 or other equipment inside the BOP 200 and / or inside the well. As best illustrated in Figure 3, the orientation pin 100 is located in the BOP 200 and can reach through the BOP 200 and project inwards, making contact with the THOJ 300. The orientation pin 100 can have an angle, for example, of three to ten degrees, relative to the horizontal, with the horizontal being perpendicular to the axis of the THOJ 300 as well as to the axis of the BOP 200. The orientation pin 100 can be arranged perpendicular to the axis of the THOJ 300, that is, perpendicular to the axis of the BOP 200.One angle can be advantageous for orienting the THOJ 300 within the BOP 200.

[0034] According to one embodiment, hydraulic power can be established through a separate subsea-based system that is integrated into the THOJ 300, therefore, in combination with what has been described in this document, this can eliminate the need for an umbilical. Alternatively, and as described in this document, hydraulic power can also be supplied through the orientation pin 100. A link between the orientation pin 100 and the surface can be made, for example, through an ROV 500. For example, when the orientation pin 100 reaches its final position on an alignment plate on the THOJ 300, it can enter an electrical connection interface slot for hydraulic power and data communication.

[0035] According to one embodiment, a system for guiding a 300 pipe hanger guide joint within a 200 wellbore and Petition 870260059124, dated 06 / 17 / 2026, p. 20 / 36 12 / 17 to provide communication is disclosed. The system comprises BOP 200. The system comprises guidance pin 100, according to any of the embodiments described herein that describe guidance pin 100. Guidance pin 100 is configured to provide guidance and communication. The system further comprises a pipe hanger orientation joint 300 which can be oriented with the orientation pin 100 and disposed within the BOP 200. The orientation pin 100 is configured to interface with the THOJ 300 and configured to provide communication between, on the one hand, an exterior of the BOP 200 and, on the other hand, the THOJ 300 or to other equipment within the well via the THOJ 300. The system may comprise any additional elements or embodiments mentioned in this document, for example, to transport fluid through the orientation pin 100 and / or transmitters / receivers 410 and 420 and / or an electrical connection and / or an inductive coupling for communication.

[0036] The communication provided by the system can be data transfer between, on the one hand, an exterior of a BOP 200 and, on the other hand, an interior of the BOP 200 or a THOJ 300 or other equipment inside the well. Communication via guidance pin 100 can be data transfer between, on the one hand, one or more of: an upper side, a subsea station, a remotely operated vehicle, ROV or BOP umbilical and, on the other hand, one or more of: downhole equipment, a control module and / or other equipment on a hanger or string, downhole sensor and meter. This communication passes through guidance pin 100 and the THOJ 300.

[0037] According to one embodiment, the system may further comprise a sealing element 120 that protects against the entry of debris between the guide pin 100 and the pipe hanger guide joint 300. For example, the sealing element 120 may protect against the entry of debris or marine riser fluid between an axial end of the guide pin 100 and the pipe hanger guide joint 300. The sealing element 120 may be a flap valve or a sliding sleeve integrated into the guide pin 100. The sealing element in the guide pin 100 may limit exposure to debris. Petition 870260059124, dated 06 / 17 / 2026, page 21 / 36 13 / 17 and / or marine riser fluid during all phases of operation.

[0038] According to one embodiment, a method is disclosed for communicating between, on the one hand, an exterior of the BOP 200 and, on the other hand, the THOJ 300 or other equipment inside the well. An orientation pin is provided in the BOP 200. The orientation pin 100 is in accordance with any of the embodiments described in this document. The method comprises the following separate steps: orienting the THOJ 300 relative to the BOP 200 using orientation pin 100, and communicating between, on the one hand, the exterior of the BOP 200 and, on the other hand, the interior of the BOP 200 or the THOJ 300 or other equipment inside the well, via orientation pin 100. Orienting the THOJ 300 relative to the BOP 200 using orientation pin 100 can be done with the aid of orientation pin 100 and this may include, for example, physical interaction to orient, physical interaction to position for subsequent orientation, initiating orientation and / or providing communication so that orientation can be performed.Alternatively, the method comprises the following separate steps: guiding, through the guidance pin 100 physically interacting with the pipe hanger guidance joint 300 or other equipment inside the well, the pipe hanger guidance joint 300 in relation to the BOP 200; and communicating between, on the one hand, the exterior of the BOP 200 and, on the other hand, the pipe hanger guidance joint 300 or other equipment inside the well, through the guidance pin 100. For example, the guidance of the pipe hanger guidance joint 300 in relation to the BOP 200 can be done by the guidance pin 100 physically interacting with the pipe hanger guidance joint 300 or other equipment inside the well. The physical interaction can, for example, be a coupling, a touch, or a guidance. The steps can be taken in any order or simultaneously.

[0039] The method may also comprise transferring energy to the pipe hanger guide joint (300) or equipment within the BOP (200), via the guide pin (100). The energy may, for example, be electrical energy and / or hydraulic energy. The energy may be between, on the one hand, the exterior of the BOP (200) and, on the other hand, the pipe hanger guide joint. Petition 870260059124, dated 06 / 17 / 2026, p. 22 / 36 14 / 17 (300) or other equipment inside the well, through the guide pin (100).

[0040] The method may further comprise conveying fluid through the guide pin 100. The guide pin 100 may be movable in its axial direction to make a fluid connection, for example, by means of a fluid connection such as a quick-connect coupling. The method may further comprise preventing debris or marine riser fluid between the guide pin 100 and the pipe hanger guide joint 300 with a sealing element 120, so that no contamination enters or disturbs the fluid connection, for example, as described herein.

[0041] The method may further comprise axially moving at least a portion of the orientation pin 100 to connect for communication. For example, when the orientation pin 100 reaches its final position on an alignment plate in the THOJ, it may enter an electrical connection interface slot for hydraulic power and / or data communication. Axial movement of the orientation pin 100 may bring the transmitters / receivers 410 and 420 into proximity to each other so that data communication can be made. Data communication may be made using an electrical connection and / or an inductive coupling. Axial movement of the orientation pin 100 may bring the electrical connector together or inductive couplings together so that data communication can be made. A connection to carry fluid through the orientation pin 100 may also be made by axially moving at least a portion of the orientation pin 100.Axial movement can connect couplings to transport fluid. Axial movement can be achieved by a separate piston arrangement as best illustrated in Figure 3, or by a ROV 500 as best illustrated in Figure 1.

[0042] The method may further comprise preventing debris between the guide pin 100 and the THOJ 300 with a sealing element 120. The method may further comprise opening the sealing element 120 on the guide pin 100 immediately before or during the connection between the guide pin 100 and the THOJ 300, thereby preventing debris or marine riser fluid from contaminating the connection. Petition 870260059124, dated 06 / 17 / 2026, page 23 / 36 15 / 17 This prevention can be done using a flap valve or a sliding sleeve arranged on the guide pin 100 as a sealing element 120.

[0043] The method may also comprise communicating between, on the one hand, the exterior of the BOP 200 and, on the other hand, the THOJ 300 or other equipment inside the well, using, via the orientation pin (100), one or more of the following: an electrical connection and / or an inductive coupling. Communication via orientation pin 100 may be the only way to communicate with the THOJ 300 or other equipment inside the well. Thus, there may be no other way to communicate with the THOJ 300 or other equipment inside the well.

[0044] Communication via guidance pin 100 can be between, on the one hand, one or more of: an upper side, a subsea station, a remotely operated vehicle, ROV or BOP umbilical and, on the other hand, one or more of: downhole equipment, a control module and / or other equipment on a hanger or string, downhole sensor and meter. Data communication between guidance pin 100 and the THOJ 300 can be done via an electrical connection and / or an inductive coupling. Other data communication can be done using one or more of the following: electrical signal, conductive signals, radio signals, light, ultrasound and high-frequency signals. While communication passes through BOP 200 as explained in this document, communication can be, for example, from an upper side, such as an offshore platform, or from a subsea station, through the BOP to the downhole equipment and back.Communication is therefore between, on the one hand, the exterior of a BOP 200 and, on the other hand, the interior of the BOP 200, and there is no need for an umbilical or communication line inside the pipeline to the sea surface. This also allows various operations to be performed when installing the THOJ, since data communication for downhole operations is immediately available. Communication can be information communication, for example, intelligence data such as command instructions, sensor data, etc. According to one embodiment, communication via guidance pin 100 is between, on the one hand, one or more of: an upper side, a subsea station, a...

[0045] As described in this document with reference to Figures 1 to 3, the orientation pin 100 is configured to orient a pipe hanger orientation joint 300 in a subsea well, and the same orientation pin 100 is configured to provide communication between, for example, an upper side of the subsea well and, for example, downhole equipment. The orientation pin 100 described in this document allows orienting, with the orientation pin 100, a THOJ 300 in a hanger; and communicating through the orientation pin 100, between the upper side and the subsea well equipment 400, using one or more of the following: electrical signal, conductive signals, radio signals, light, ultrasound, and high-frequency signals. Preferably, the orientation pin 100 comprises an electrical connection and / or an inductive coupling configured for communication.The guide pin 100 can be extended against the THOJ 300 at the end of the settling column once the column is initially seated for installation or retrieval of the THOJ 300. The column can move the THOJ to allow the guide pin 100 to rotate, guiding the THOJ 300 by the guide pin 100 engaging in an alignment slot 310, as best illustrated in Figure 2. The column is fully seated when the guide pin reaches its final position within the alignment slot 310, thus guiding the THOJ. The guide pin 100 can be hydraulically actuated to extend or retract the guide pin 100 from the BOP hole; alternatively, the guide pin 100 can be moved by electrical and mechanical means.
