    An apparatus for attaching a flexible line, such as a multiconductor electric cable for power and control circuits, a single flexible hose, or conventional flexible cables to a subsea station by remotely controlled means and without the assistance of divers or diver capsules or submarines. The apparatus includes a cable connecting frame structure upon which is pivotally mounted a socket-like container means which receives a receptacle means connected at one end of a flexible power cable or line. The frame structure is adapted to be releasably attached to the subsea station. A plug assembly is receivable by the socket-like container for electrical engagement with the receptacle means, and lock means holds the socket-line container in a selected position with respect to the subsea station. A method of connecting a flexible line to a subsea station in which a cable connecting frame structure carrying a socket-like container receiving a receptacle means provided at one end the power line is lowered to the subsea station by a running tool which has latched engagement with the frame structure and holds latch members on the frame structure in release position for reception of guide posts on the subsea station. Release of the running tool from its latched engagement with the frame structure provides latching of the frame structure to the guide posts so that the running tool may be retrieved. A method in which the running tool may also be used for retrieving the frame structure for service of the electrical receptacle means carried by the frame structure.

    FIG. 1 shows a ship over a station and a ship unloading a cable; FIG. 2 shows the guide frame and the mounting tool prior to contact with the subsea station; Fig. 3 shows section A-A of Fig. 2; Fig. 4 shows a guide frame and a mounting tool in a detachable position; in Fig. 5 a section of the guide post of the underwater station; in fig. Figure 6 shows the directional support with the removal of the guide sleeve; in fig. 7 shows the electrical connection to the underwater station; in fig. 8 shows the trunnion in the locked position. At the underwater station 1, a vessel 2 is provided, equipped with a drilling rig 3 and having an opening 4 through which the string of drill rods 5 can pass to lower the guide frame b to the underwater station 1. The guide frame 6 is directed to the posts 7 of station 1 with the help of two cables 8 wound on winch 9 under constant tension. The vessel 10 is a discharge cable, provided with a drum 11 on which cable 12 can be retained and stored. The cable is unwound from the reel 11 through the bushing 13 and has a cable socket 14 at the free end. The flexible electrical cable carries several circuits for controlling the operations of the underwater station. The guide frame 6 is provided with guide sleeves 15 that are spaced in which the stands 7 are included. The sleeves 15 have extended lower ends 16 to help guide the sleeves to the stands 7. The sleeves are connected with an inverted U-shaped skayboy 17 seconds bent outward by their ends 18, welded to the couplings, in addition, they are reinforced with kerchiefs 19. Bent ends 18 carry from their inner side rolling support 20, which includes trunnions 21 of the receiving unit in the form of a sleeve 22, swinging around support 20. The node connecting the flexible cable with The lid frame is designed as a sleeve 22 with a longitudinal notch 23. The lower part of the sleeve 22 has a protrusion 24. The ring 25 limits the cavity for receiving the protrusion 24. The locking means includes a chamber 26 which has a cavity 27 provided for inserting the trunnions 21 and holding however, with the vertical position of the sleeve 22, being able to rotate the sleeve in the support when it is not in the vertical position facilitates the downward movement of the frame b when it carries the electric cable 12 i.e. the sleeve is pumped, adjusting to the loads caused by cable 12 when the latter is connected to the vessel 10 and the frame 6 is in the process of lowering to the submarine station 1. The cable socket 14 has a T-shaped lug 28, which slides into the sleeve 22. The tip of the lug is provided ring 29, which engages with ring 30. The cable socket is secured to the bottom of the sleeve with bolts 31. Connector 32 is held in contact with tip 28 by means of a container 33 filled with heavy material, such as lead. Between the tank and the connector it is possible to install the drum 34, from which you can unwind the appropriate length of cable to connect to the equipment of the surface station. The frame 6 is lowered along the guide cables 8, unwinding the cable 12 from the reel 11, using a string of drill rods 5.. When the frame 6 comes to station 1, the sleeves 15 are located on the guide posts 7. The sleeves are blocked in racks on have locking grooves 35. In the grooves 35 there are mounted annular elements 36 with compression springs 37 and fixed with screws 38. The mounting tool 39 consists of two cylindrical elements 40 for guiding and locking, interconnected by a transverse rod 41. Each cylindrical element The copier has an opening for the passage of the guide cable 8. The transverse rod 41 is provided with a chuck 42 with a working connector 43 equipped with locking devices 44, which are locked to the cartridge when the working connector is lowered. Pipeline 45 for pressurized fluid ps (provides a drive fluid to release the locking devices 44 when the mounting tool 39 is to be separated from the drill string at the station. Each cylindrical member 40 is provided for detachable connection with the guide sleeves 15. When the member 40 is coupling 15, the mounting tool 39 can, by means of the column of rods 5, lower the frame 6 to the underwater station or remove the frame from the station, releasing the locking device between the coupling 15 and the station 7. The cylindrical member 40 consists of a body 46 provided with a lid 47 with an opening 48. The lower part of the body is provided with an inner annular part 49 for contacting a shoulder 50 to restrict the mounting mechanism to move downward relative to the frame. from pauvu 6 and from the guide sleeves 15 is composed of a pressurized fluid supply pipe 51, which may be located along the string of drill rods 5
    and which may be getsienen with the help of other tubes b / c with an unlocking device provided on each locking cylinder 40 of the mounting tool 39.
    The tube 52 is connected to an unlocking device having a cylinder 53, in which an equation moves, equipped with a rod 54 connected to its upper end pivotally with a leg 55 fixed in a corresponding manner on the cylindrical wall 56. Pressurizing the lower part of the cylinder 53 shifts the ring element 57 upward, tabs 55 slide along longitudinal notches 58 in cylindrical body 46. Expanding heads 59 move radially from the center, ensuring separation of the mounting mechanism from the frame. Compression springs 37 eject the BcUOT bushing 60. The mounting mechanism may be removed from the frame.
    When the frame has to be removed, the mounting mechanism 39 is lowered along the guide cables and guided to the posts 7. The ring member 57 contacts the top edges of the locking sleeve 60, punching it down and compressing the spring 37 and releasing the ring members 36 from the guide racks. Expanding heads 60 enter shoulders on the outer surface of sleeve 15. When this interlock is secured, frame 6 can be moved upward, freeing it from guide pillars 7 and removed for caring for cable connector 14, while with a capacity of 33 removed.
    The device allows distance control of the connection and disconnection of the cable socket to the underwater station.
