On each side there are two guide rails 30 for connecting modules, and in the center - one Central guide base 31 for the Central control module 29, equipped with two receivers 32 for internal electro-hydraulic multi-channel connectors 33.
    On the side of the distribution frame 12, two sockets 34 are fixed, connected to the base of the pipelines 7 on the base 1. The number of peripheral sockets corresponds to the number of well heads. The plinths 30 and 31 may be mounted or may be an integral part of the distribution frame 12. Their designs are identical to those of the guides of the known plinths.
    In this case, the square frame of the cap contains struts located diagonally on which the coupling 4 is fixed along the axis, made to be gripped and locked by the connector. Four guide columns 3 of moderate length are installed at the four corners of the square.
    The base 30 is designed to install the connecting module 28, made in the form of a square case containing the upper plate 35, connected at four corners by means of guide sleeves 36 with a channel frame 37. A receiver for the internal multi-channel connector 38 is fixed along the axis of the modules on the upper part of the plate 35 and coupling 4, and on the lower part of the casing - mechanical! connector 21 for gripping and locking the clutch 4 of the distribution frame. Inside there is a multi-pass flexible loop 39, ending with a connector 25 connection with the control output of the device P 26 for Christmas tree waste. On the top plate 35, on either side of the center, there are two guide columns 18.
    The equipment of this module is supplemented by a hydraulic drive system providing operation of the mechanical connector 21, and other hydraulic systems connected to the socket of the production head, in particular 21, providing a connection between the connecting module and the output coupling of the borehole head.
    The guide columns 18 are designed for angular positioning 2ί of the control module 24 with the help of bushings 40, placed in the module, which is made in the form of a housing closed by a plate 41. Two columns 18 and a coupling 4 are fixed on the latter, as in module 28, as well female portion 42 of the internal multi-channel connector. On the sides of the module there is an external multi-channel connector 25 for communication with a Christmas tree 16 and a receiver for an outdoor multi-channel connector for communication with a central control module 29 (multi-channel connector 43). The equipment of the module is supplemented by electronic and electro-hydraulic containers 44.

    The Central guide base 31 of the distribution frame 12 is designed to install on it a Central control unit 29, the housing of which is formed by the upper plate 46. At the four corners of the plate 46 are fixed guide bushings 47 designed to slide along the columns 3 of the distribution frame.
    In addition, the module has four external electro-hydraulic multi-channel connectors 43 for connecting to the receiver of the control module 24, one or two internal electro-hydraulic multi-channel connectors 48 connecting this unit to the female part of the multi-channel connectors 33 on the distribution frame 1 2 and other external and movable male multi-channel sockets 49 connecting the module with each control module 24, as well as external multi-channel connectors 50. Inside the module are placed containers 51 for hydraulic , electronic and electro-hydraulic systems.
    Each section where module installation is expected, and each module that remains temporarily or permanently without a module, after its final installation is protected by a -52 shield of modular design, i.e. a plate 53 absorbing impact energy, which is connected to a skirt 54 serving as a gas trap. Two guide tubes 55 s are installed on it.

    The operations of installing the modules are performed by the manipulator 57 stacking and joining. It is made in the form of a mast of a crane 58, mounted axially on a plate or base 59, equipped with two guide pipes 60 for guiding the columns 18 placed on both sides of the center of the plate, and four guide funnels 61 mounted on the corners of the plate for lowering by linear sliding guides mounted on the guide columns 3 of the base. The connecting element 62 at the top of the mast for a group of rods allows its descent from a floating means. The internal multi-port * 63 connector is used to transmit electric and hydraulic commands for bundling cables and pipelines from the surface to a module mounted on the manipulator. On the upper part of the plate there is axially mounted a mechanical connector 21, designed to capture the coupling 4 of a unified design, which is available in any module. A telescopic crane 25 boom 64 with a manipulation cap acting on multichannel connectors is articulated on the mast in the form of a manipulation organ 65 equipped with visual indication means 66. The manipulation area is equipped with electro-hydraulic drives for moving, locking and unlocking external multi-channel connectors on operating modules, 35
    Installation of the underwater station is as follows.
    With the help of the descent equipment, a base 1 is laid on the bottom of the sea, equipped with guiding socles, ^ and level it using the appropriate mechanisms. After drilling head mounted four wells and wells 1.5 shields similar shield 52 is lowered and ustanav ~ 45 Lebanon distribution frame 12 in
    I zone provided in a central portion of the base plate from the rack rails 13, onto which the guide sleeves 14. 50
    The descent of the module, which is the operating unit, can be carried out using the manipulator 57. Locked using the connector 21 on the clutch 4 of the module and positioned in the angular position using the columns 18 included in the guide tubes of the manipulator, the module is lowered from the vessel using a group of rods along linear guides attached to the columns 3. Thanks to the visual indication means 66 mounted on the manipulator, the module, lowered near the selected base location, is positioned in an angular position so that yre guide sleeve 10 of the module 22 have been planted on the four pillars of the guide cap 3. After installation, the module is blocked on the guide base with the help of a manipulation body 65, which provides blocking of the mechanical connector 21 of the module on the base coupling 4 and the functional operations of the module. After installing the module, the mechanical connections between the manipulator and the module are disconnected using the organ 65, and the manipulator is again released to perform other operations. The base, to which all the electro-hydraulic connections of the hose converge, is lowered and blocked in the area formed on the side of the distribution frame with the help of two couplings and guide racks 10 of the base, interacting with the guide tubes of the base. Then the hose is laid at the bottom of the sea to the control unit on the surface, which can be several tens of kilometers from the station, and / or to the buoy, anchored a few hundred meters from the station. Four connecting modules 28 are lowered and mounted on the guide plinths in the same way. Then, a control module 24 is installed on the top of each module 28. Direction in the immediate vicinity is provided by columns 18, which must enter the bushings located inside the modules 24. During this operation, the male multi-channel connector 46 'is connected to the female multi-channel connector 38 of the connecting module 28. Then, in the same manner, the central unit 29 is lowered onto the distribution frame.
    Manipulator 57 makes electrical and hydraulic connections between the various modules. So, it drives multi-channel. Connectors and provides connections between the Central control module and the hose 8 (connector 50 to the coupling 4), the Central control module 29 and the control module 24, the connecting module 28 and the block of the well head 15; control module 5 module 24 and the block of the head 15 of the well (connector 25 and connector 23), pipelines of the distribution frame and production pipelines (connector 34 on the base 2). 10
    The connections between the distributor modules and the modules on the base are made by means of connections allowing a relative position deviation. As for the internal connections of the modules on the distributor, the rapprochement of the connected parts is such that less flexible materials with a small Deviation, for example, 2 ° between the central control module 24 and the actuators of the internal valves of the distributor, can be used for connections.
    The advantages of such a modular design of a submarine station are significant. No control equipment was installed above the block of the head 15 of the well. On the contrary, such equipment is partially installed on the connecting module 28 (wear-adjustable nozzle 30) and partially on the control module (electro-hydraulic distributor to the connecting module 28 and the head module 15 of the well after decoding the commands). 35
    Thus, all less reliable modules are placed on top so that access to them is facilitated — and manipulation with them outside the head 15 of the production well. Each less reliable 40 module can be lifted directly with the help of a manipulator 57, which independently disengages all mutual connections thanks to the organ 65. The lifting and lowering operations carried out by the manipulator 45 are carried out with axial application of forces to each module thanks to the 4-connector coupling system 21 mounted axially on each module. fifty
