  • ABSTRACT [30] Foreign Application Priority Data A method for installing underwater equipment on at Dec. 27, 1971 France 71.46720 Previously installed underwater guide Structure
  • the underwater equipment is divided into at least a first 52 US. Cl. l66/.6 unit and a Second unit, and the first unit is first 51] 213 33/035 ered from a surface support onto the guide structure 58 Field of Search 166/.5-, .6 y means of a manipulator, the Second unit is then lowered into place on top of the first unit, and then 5 References Cited the two units are connected together.
  • the underwater Steps can be accomplished either means Of a remote-controlled manipulator or by a crew working in a work bell or a submersible.
  • This invention relates to a method for the installation and control of any underwater equipment, and more particularly to a method for the installation and control of an underwater oil well access equipment for the working of wells located at great depths, especially depths greater than those within access of a diver.
  • This invention provides a method for the installation and control of an underwater oil-well head located at great depth and having its base surrounded by any structure which has served for drilling the well, characterized in that a supporting structure round the casing head is lowered in a first phase from a surface, support and by means of a remote-controlled manipulator.
  • a first detachable integrated unit In a second phase and by means of a manipulator remotecontrolled from the surface a first detachable integrated unit is lowered, which has the function of serving as a seating for a second integrated unit as well as means of intermediate connection between the latter and the casing head in order both to ensure the continuity of the production passages and the opening or closing of these passages upstream of the second unit and also to ensure the continuity, opening, and closing of a gathering passage proceeding from this second unit.
  • the gathering passage from the first unit is connected to an underwater gathering system of pipes, each passage being controlled by means of a valve operated by any suitable external manipulator.
  • the second integrated unit In a third phase and by means of a manipulator remotecontrolled from the surface, the second integrated unit is lowered, the latter having the function on the one hand of a production tree ensuring control of the flow in the production and gathering passages, discharge being effected normally through the underwater gathering system of pipes, and on the other hand the function of a means of intermediate connection between the well and any surface support with a view to transmitting any information on pressure, temperature, and flow and receiving from the surface any valve opening, closing, or adjusting commands. Such information can be transmitted either by means of the manipulator or withdrawal of the latter, by remote control.
  • the joining of the second unit to the first is facilitated by equipping each of the members, the first unit and manipulator, with a guide and protection structure so that in the course of the lowering of the second unit the latter can possibly take on a certain tilt and a certain offset relative to the axis of connection of the first and second units without risk of damage to the portions of these units employed for the connection, as is often the case when the devices to be connected at the seabed are only furnished with conventional impact dampers.
  • the presentation of the second unit relative to the first is perfected by guiding a frame connected to the manipulator by means of the guide structure surrounding the first unit and by displacing the manipulator connected to the surface support, laterally and vertically relative to the frame.
  • a structure In advance of the first unit a structure is lowered to surround the casing head in a watertight manner whilst being supported vertically on a surface pipestring and laterally on a clamping device between the said structure and the outer conductor string so as to serve as a supporting base.
  • the first unit is lowered by means of a diving-bell that has been allowed to rest on this base. It is then sufficient next to empty the bell by any known means and to admit to it air at atmospheric pressure and then a work-crew in order to proceed with the placing of the first unit under the control of this crew.
  • the advantage of this method is in being able to install the equipments necessary to the exploitation of an underwater oilfield, such as a production wellhead, at great depth automatically in complete safety, the prior lowering of the first integrated unit enabling through the possibility of operating valves controlling the production passages, the avoidance of any premature setting of the well in action during the placing of the second unit and of checking straight from the surface the satisfactory operation of all the control devices of the second unit after its connection with the first.
  • Another advantage of this method is that, as opposed to previous methods in which in order to treat failures of a complex underwater equipment such as a wellhead or a separator one was compelled to intervene frequently over a multiplicity of devices each fulfilling a simple function and arranged so as to be accessible to intervention manually or by a manipulator, which caused numerous interruptions in production and multiplied the risks of damage or the impossibility of intervention because of bad weather, it is sufficient to proceed to the simple withdrawal of the unit containing the various control members, to replace it immediately with an identical unit in accordance with the method shown and to repair the defective unit at the surface.
  • Another advantage of this method is in being able to proceed at the smallest cost with preventive maintenance of the most elaborate and often the least reliable underwater equipment by standard exchange at fixed intervals of the unit containing this equipment.
  • FIG. 1 shows a perspective view of the lower guide structure of an underwater wellhead access equipment
  • FIG. 2 shows a perspective view of a supporting structure lowered from a surface support
  • FIG. 3 shows the assembly of the structures shown in FIGS. 1 and 2;
  • FIG. 4 shows a partial diagrammatic view of a device ensuring locking of the tool carrying the supporting structure of FIG. 2 with the said structure;

  • FIG. 7 shows a diagrammatic elevation of the remote-controlled load-carrying tool surrounding a wellhead equipment
  • FIG. 8 shows a diagrammatic view of a device for separation of the detachable units.
  • FIGS. ll, 2, 3 and 4 the underwater wellhead access equipment to be installed and controlled has been described in applicants copending patent application Ser. No. 318,972 filed on Dec. 27, 1972, and titled A Well-Head Assembly.
  • a conventional guide structure such as that shown at 1 in FIG. 1 has previously been placed on the seabed by any known means.
  • This structure surrounds the outer conductor string 2 and comprises essentially a rigid frame 3 serving as a support to vertical guide bars 4, and a base 5.
  • a unit 8 having pipes 14 for gathering oil from the well head is lowered by means of a pipe column 6 or riser, including all the means of remote control and remote transmission, to which is. connected a remote controlled manipulator 7, carrying all the means of location and propulsion.
  • the lowering of this first unit is effected without a guideline connecting the surface to the well, by neutralizing the effects of the swell by any known antipounding system and by providing at least one means enabling suppression of torque which would be exerted on the column during the movement of the ship 9 or any other surface support.
  • the manipulator 7, which can be of any type and comprises particularly means of self-guidance and selfpropulsion, is attached to the end of the column 6.
  • it supports a supporting connector, partly seen at 10 in FIG. 3, the unit 8 being connected to the support plate 11 in FIG. 3, the bearing I plate 64 in FIG. 5, or the support plate 75 in FIG. 6,
  • the bearing plate 64 is provided with a center hole of sufficient diameter to let the upper portion of the connector 10 pass through it and to rest by its periphery on a flange l2 seen in FIG. 5 and located on the lower portion of the connector 10.
  • the support plates 11 or 75 may be similarly supported, and, as seen in FIG. 5, the support plate 11 may also be provided with appropriate apertures 22 for the passage of the pipes 14, which are connected to gathering pipes 68, also seen in FIG. 5 can include a structure 76 for protection of the casing head 17 and guidance of a tool-carrier frame 30, FIG. 7, which will be described later.
  • the supporting connector 10 can be connected to the plate ll, 64, or 75 in a watertight manner.
  • the unit 8 When the unit 8 is sufficiently near the guide bars 4 and the skirt 13 is right over the top of all the bars, the unit 8 is orientated by means of the remote controlled manipulator 7 so that the cutaway corners 11a of the plate 11 are nearly above the bars 4.
  • Guide surfaces such as 15, for exam- 1 ple, FIG. 2, located below the plate 11, at the instant of the lowering of the remote-controlled manipulator 7 guide the bars 4 through the holes 16, FIG. 3, provided in the plate 11.
  • controlled manipulator 7 and/or another manipulator I such as the tool-carrier 77 (shown in FIG. 4) are raised again and lowering proceeds of a first detachable integrated unit as seen in FIGS. 5, 6 and 7 and bounded in FIG. 5 between the dotted lines 62 and 63.
  • Tool-carrier 77 or manipulator 7 is also used to install the supporting connector 10, in contrast to tool-carrier frame .30, it
  • means are provided on'toolcarrier 77 for locking it to supporting connector 110.
  • These means comprise spring 20, piston 19, cylinder 78, slot 10A in the supporting connector 10, and hydraulic tube 21 containing the control oil for the locking operation.
  • the control oil is used to push the piston 19 leftwards against the bias of the spring 20 when it is desired to unlock the tool-carrier 77 from the supporting connector 10.
  • FIG. 2 can take manifold forms, such as that shown in FIG. 5.;In
  • connector 10 supports from the flange 12 a bearing plate 64 provided at its periphery with annular surfaces 65 and 66 constituting with the connector 10 a completely watertight unit.j
  • Passages such as 67 enable the connection of the gathering pipe 68 of the unit 61 to an underwater gathering system of pipes by means of connectors of any known type.
  • a bell, or submersible unit, carrying the unit 61 is lowered from the ship 9 by means of the manipulator 7.
  • the bell can be of any known type and does not in itself form part of the invention it has not been shown.
  • a work-crew lowered by any means provided with a lock chamber for connection to the bell then proceeds, after replacement of the water trapped by the bell with air at near to atmospheric pressure, to unlock the unit 61 from its support and lower it in order to fit it onto the casing head I17 and to connect the gathering pipe 68 to the passage 67.
  • a connector 70 locks the unit 6l onto the casing head ,17.
  • Means 71 shown schematically in FIG. 5, permit orientation of unit 61 with respect to casing head 17.
  • the valve 72 which controls the production
  • a valve 73 which controls the.pipe connected to the annular space
  • valve 74 which controlls the gathering pipework can be operated manually or by any sort of manipulator device.
  • a tool-carrier frame can also be employed, such as that shown diagrammatically at 30 in FIG. 7, which serves to protect and to fix in the working position the two integrated units 61 and 26.
  • the frame and the two units 26 and 61 have been shown to the exclusion of any guide or protective structure.
  • the units 61 and 26 (the outer contours of which are designated by the broken line 40) have besides been shown so as to make the valves 72, 73, 74 and 27, 28 and 29 appear opposite to corresponding actuators 34, 35, 36 and 37, 38 and 39 carried by the tool-carrier frame 30 and remote controlled by any known system.
  • This frame is attached to the end of the column 6 at the level of a guide and support plate 33 surrounding the collar for connecting the remote controlled manipulator 7 to the column 6.
  • This adjustment is enabled by the lateral displacement of the support and guide plate 33 which in turn is guided and supported by the plates 81 and 82, and the vertical displacement of jacks 32, the rods 32a of which control the engagement of the male portion of the connector 70 in the female portion at the top of the casing head 17.
  • the unit 26 is lowered onto the unit 61 by means of the frame 30 while supporting this unit by the remote con trolled manipulator 7, the later being connected to the ship 9 by the column 6.
  • the frame 30 meets the guide structure which is associated with it, for example, the arches 79 in FIG. 6, it is guided in such a way that its axis coincides approximately with that of the axis of the unit 61.
  • the arches 79 may be joined together by a ring member such as ring member 80, also shown in FIG. 6.
  • the exact squaring up and connection of the unit 26 on the unit 61 is effected by any means, for example, by a connector 26a similar to that employed for the connection of the unit 61 to the casing head 17 and by the action of the jacks 32 and the plate 33.
  • the system of remote control of, and remote transmission from, the underwater equipment is put into service in order to establish control of the equipment from a central control station.

  • the tool-carrier frame 30 with the manipulator 7 are lowered at the end of the column 6 and the operations of disconnection of the unit 26 are carried out after guiding and placing the frame 30 onto the plate 75 in the same fashion as before.
  • closing of the valves of the units 61 and 26 proceeds by the remotecontrolled actuators 34 to 36 and 37 to 39 on the frame 30, and the connector 26a is disconnected by the same remote control means as used for connecting up.
  • the disconnection of the unit 61 which generally is less frequent, is likewise carried out by means of the tool-carrier frame 30 and the bell, if the latter was employed for the erection, by disconnecting the connector form the casing head 17 either by remote control or manually inside the bell.
  • FIG. 8 by way of example, there is shown a jack 41 on the frame 30 for facilitating the withdrawal of the unit 26 after disconnection, by simple engagement of a cam 43 between two rollers 44 by means of the rod 42, the displacement of the upper roller bringing about the raising of the unit 26 through the rod 46 slidably mounted in the guides 47.
