    DK 2020 00013 U1 1 Apparatus for launching and salvaging a submarine from and to an offshore site Field of production The present invention relates to an apparatus for launching and salvaging a submarine from and to an offshore drilling site, such as an offshore drilling site, which apparatus comprises: a support platform located on the offshore site and a frame rotatably mounted on the support platform and having side supports, and a top beam suspended between the side supports of the frame, a displacement unit for selectively displacing the frame from an inboard position within the offshore site boundaries to an outboard position outside the offshore site boundaries, a launching / salvage cable that passes the frame and has a first end for suspending the submarine from the offshore site when the submarine is launched; and salvage, a hoist coupled to another end of the launching / salvage cable which hoist is ten In operational roll-out and roll-up of the pickling rope when the underwater starter is launched and salvaged, respectively. in particular, the invention relates to the launching and salvage of a submarine using a so-called A-frame on a platform on a ship.
    Background of production The launching and salvage of a submarine from and to an offshore site, often a ship, is carried out with a crane on the ship capable of reaching outside a railing on the ship.
    The crane can be a boom crane with telescopically extending booms, the extension and insertion of the drills being driven by hydraulics in order to pull out or retract the crane's booms. The crane can also be a cantilever crane with cantilever rotating relative to an upright column, the delivery of the cantilever also being driven hydraulically. The crane can also be a lattice crane with lattice booms that rotate relative to each other, as rotation of the booms is also driven hydraulically.
    The crane can also be an A-frame crane with a frame that rotates between an inboard position inside a ship's railing and an outboard position outside a ship's
    DK 2020 00013 U1 2 railing, as turning of the frame is also performed with contribution. The outboard position is the position Ul launching into the sea and salvaging the submarine from the sea. The inboard position is the position for storing the underwater starter on the ship.
    Operation of the booms, boom or frame with hydraulics has the advantage that it is possible to achieve the necessary power for launching and for salvaging the submarine by simply dimensioning the hydraulic system according to the needs for power. Various hydraulic systems are easily accessible. However, hydraulic systems also have drawbacks that are not recognized.
    Hydraulic system and engines that drive the hydraulic systems make a lot of noise and pollute the immediate surroundings, both of which annoy the staff on the ship. Hydraulic systems can also, over time or suddenly, spill oil on the ship's deck and into the sea, making the deck slippery for the crew on the ship and polluting the sea. The power consumption is high on a bydrsulik system because the efficiency is low and a hydraulic pump unit in the hydraulic system runs during the entire operation of the submarine, even when the submarine is launched in the sea, for constant backfilling of the contribulik system, which is clear ul trvkk capacity at any time during operation, and even if from time to time everything else, such as during launching of the submarine, the hydraulic system is not needed. The apparatus for seeing and salvaging a submarine is often provided with roll-compensating hydraulic pistons and / or surge-compensating hydraulic motors and possibly also with a lock box operated by contributors, these elements of the apparatus being positioned outside the offshore site during operation. of the submarine. Any spilled hydraulic oil from these elements is spilled directly into the sea. The object of the invention It is an object of the present invention to provide an apparatus which eliminates the disadvantages of existing cranes for launching and salvaging a submarine from and to a ship.

    When the actuators are operated with electricity, and not with hydraulic fluid, it has the advantage that it is possible to use energy for the operation of the actuators only when the actuators are actually working. does not work because it takes time to build up pressure in a hydraulic system, if there is a sudden need for such pressure. Likewise, any risk of spilling hydraulic fluid on the ship's deck and / or in the sea is also avoided. The risk of injury to staff is avoided if the injury is due to slipping in contributory fluid. The risk of contaminating the sea with hydraulic fluid is avoided, and the risk of being fined for spilling hydraulic fluid into the sea is also avoided. Furthermore, noise from machinery operating contribution pumps is avoided, which is an advantage for the staff on board the ship. According to one possible embodiment of the invention, the apparatus has roller actuators arranged between the frame and the actively operated gimbal joint, which roller actuators are intended for and capable of stabilizing the movement of the submarine by suspension mold in the frame, the stabilization of movement being against offshore rolling movements. the shock.

Similarly, operation of the actuators can be faster, and operation of the rolling actuators can also be more precise, because electric motors are easier and faster to control than urban. drautic motors and hydraulic valves, possibly with leaks from contributory couplings. According to another possible embodiment of the invention, the apparatus has push actuators arranged between the frame and the actuated gimbal, which roller actuators are intended for and capable of stabilizing the movement of the submarine by suspension in the frame, the stabilization of movement being against threshing motifs for the offshore site.

Likewise, operation of the actuators can be faster, and operation of the dowel activators can also be more practical, because electric motors are easier and faster to control than hydraulic motors and hydraulic valves, possibly with leaks from hydraulic couplings. According to yet another possible embodiment of the invention, the apparatus has a ring gear arranged between the frame and a coupling plate, the ring gear having a gear wheel extending about a substantially vertical axis and can be driven by an electric motor which is intended for and 1 able to rotate the gear around the vertical axis, and where the coupling plate is rotated about the vertical axis when the ring gear is operated.
    An electrically driven ring gear has the same advantages as mentioned above. Similarly, operation of the ring gear can be faster and operation of the ring gear actuators can also be more precise because electric motors are easier and faster to control than hydraulic motors and hydraulic valves. , possibly with leaks from hydraulic couplings.
    According to yet another possible embodiment of the invention, biasing elements are provided between the actively operated gimbal and a brake ring arranged between the actively operated gimbal and the submarine, which biasing elements are intended for and capable of damping the movements of the submarine.

    The use of any situation where a solid, such as the submarine being displaced, is displaced by gravity, rather than forced by the crane's operating system, provides an opportunity for regeneration of power and energy to the operating system.
    However, if a load in hydraulic systems applies a pressure force to the hydraulic fluid, the applied irrigation force will be lost as heat. However, if a load in electrical systems applies parts of the system to a mechanical torque, the torque can be applied to a shaft of an electric motor and the applied force used to generate electrical energy.
    According to another possible embodiment of the second aspect of the generation - the batteries are capable of being charged by the electric motor to the hoist, where the electric motor during passive rotation, compared to active rotation when operating as a motor and when the motor shaft is applied to a torque, is capable of generating electric power, and - the electric motor generates after initial launching of the submarine and during downward displacement of the submarine into the sea electric power for charging the batteries by the submarine pulling due to a submarine displacement by gravity the launching / salvage cable down towards the seabed.

As mentioned above, in any situation where a solid such as the submarine is displaced by gravity rather than by forces applied by operating the electrical system, the forces can be used to regenerate electrical energy for the batteries. Holge yet another possible embodiment of the second aspect of the generation - the batteries are capable of being charged by any electric motor to any sputtering actuators and / or roller actuators, during passive rotation of the electric motor, compared to active rotation when operating as an engine, and when the engine shaft is subjected to a torque where the engine is capable of generating electric power, the electric motors are stabilized during launching of the submarine from the frame and until it reaches sea level, by means of any preferably of the actuators, which stabilization comprises that the electric motors for the actuators interrupt the movement of the cardan joint, during which interruption of movement electrical power is generated for charging the batteries.

    Description of the drawing Figs. Fig. 1 is a drawing of a possible embodiment of an apparatus according to any first or second aspect of the invention, Fig. 2 is a sketch of a possible embodiment of an actively operated universal joint for an apparatus according to the invention, and 3 is a possible layout of an electrical circuit for, or is part of, an apparatus according to the invention.
    Detailed Description of the Generation FIG. 1 is a drawing of an apparatus with a crane configured as a so-called A-frame.
    The crane has a support platform 1 and a frame 2 with side supports 3 and an upper support 4. The crane is intended to be located at an offshore location, preferably located on a ship.
    The frame 2 can be displaced between a position which is inboard in relation to the boundaries of a ship and a position which is outboard, as shown, in relation to the boundaries of the ship.
    Displacement is a rotational movement of the frame 2 about support bearings 5 at a bottom of each side support.
    Displacement of the frame 2 between the inboard position and the outboard position and vice versa is provided by electric motors (not shown) for electric actuators 7 mounted at one end & on the platform 1 and with a
    DK 2020 00013 U1 8 spiodel 9 is mounted on the side supports 3 of the frame 2, and pushing and pulling of the frame 2 between the positions when the electric actuators 7 are operated. A submarine 10 hangs between the side supports 3 of the frame 3. The submarine 10 is intended to be launched by immersing the submarine + the sea along the side or along the stern of the ship. Seaworthiness of the submarine 10 in the sea is performed by allowing a launching / salvage cable 11, 1 on which the submarine 10 is suspended, to be unrolled from a cable car 12 powered by an electric motor. When the submarine 10 has been launched into the sea and has performed tasks for 10 seas as intended, the submarine 10 must be rescued from the sea again. Salvage of the submarine 10 up from the beacon is performed by activating the launching / salvage cable 11, in which the submarine 10 is suspended, for the purpose of winding up the hoist 12 driven by the electric motor.
    The launch / salvage cable 11 rolls along a pulley 13 located in the upper beam of the frame 2. When the launch / salvage cable 11 is allowed passive unrolling during launching of the submarine 10, and the cable hoist 12 is allowed passive rolling along the launch / the salvage cable 11 at the launch of the submarine 10 into the sea towards the seabed, away from the frame 2. When the launch / salvage cable 11 is activated and wound up during salvage of the submarine 10, the cable hoist 12 rolls along the cable 11, pulling the submarine 10 through the sea, towards the sea surface, towards the frame 2.
    When launching the submarine 10, the launch / salvage cable 11 and the cable hoist 12 are pulled and rotated, respectively, by the submarine 10 sinking into the sea. Launching of the submarine 10 into the sea is achieved by decreasing the potential energy of the submarine 10, the decreasing potential exclusive right of the submarine 10 is converted into kinetic energy 1 of the cable hoist 12, the kinetic energy or rotation of the cable hoist 12. A shaft of an electric motor is coupled to] a rotary shaft of the cable hoist 12. Rotation of the cable hoist 12 when the submarine 10 is launched can be converted into electrical energy. The electrical energy can be used to charge electric batteries. There is no need for any external power, only gravity power, for launching the submarine. The gravitational energy can thus be converted into electrical energy, which charges batteries to operate the appliance when needed.
    DK 2020 00013 U1 9 Fig. 2 is a sketch showing a possible embodiment of an actively operated universal joint for an apparatus. The actively operated gimbal is suspended in the launching / salvage cable (see fig. 1} within the side supports (see fig. 1) and the upper beam of the frame (see fig. D. The actively operated gimbal is arranged intermediately between the launching ratchet cable and the submarine. operated gimbal joints are intended to support and control the movement of the submarine when suspended in the launching / salvage cable and when the frame is rotated between the inboard position and the outboard position and vice versa. If the submarine 10 is merely suspended in the launching / salvage cable, the movements of the ship make the movements of the submarine 10 unregulated and can lead to damage to the submarine, to the frame, to the ship and possibly also to the injury of people operating the device.
    The movements of the ship may be swelling, which are upward and downward movements of the ship, and / or thrust, which are longitudinal movements about transverse axes of the ship, and / or rolling, which are transverse movements about longitudinal axes of the ship.
    The actuated universal joint has roller actuators 14 located between an impact bar 15 and a support strut 16 of the actuated universal joint. The roller actuators 14 are electric actuators with a spindle extending from a housing and an electric motor (not shown) driving the spade. The roller actuators 14 can be operated to control the movements of the submarine 10 depending on the rolling movements of the ship. The actively operated universal joint also has a ring gear 17 which is arranged between the support strut 16 and a locking box 18. The ring gear 17 is electric and has a toothed sleeve 19 which is | able to rotate about a vertical axis, the gear is driven by an electric motor 20. The gear 19 can be operated to control the alignment of rotation of the submarine 10 about the vertical axis. Rotation of the submarine 10 about the vertical axis may be necessary for the submarine 10 to be aligned between the side support of the frame during launching and during salvage of the submarine when the frame of the submarine 10 supported between
    DK 2020 00013 U1 10 limb the side supports, rotate from an inboard position to an outboard position and vice versa. The actively operated gimbal joint also has a locking box 18 arranged between the ring gear 17 and a brake ring 21. The locking box 18 is intended to support the submarine 10 and lock the submarine 10 ul to the actively operated gimbal when the submarine 10 is salvaged all the way towards the actively operated gimbal joint. When providing a locking box 18, the launching / salvaging cable need not hold the weight of the submarine 10 when the submarine 10 is completely salvaged, during transport between different locations for use of the submarine 10. The locking box 18 is operated so that a coupling plate 22, with a swallow tail shape at the top, locked between clamps 23 in the lock box 18. Clamp 23 in the lock box 19 can be released by electrical operators (not shown) releasing the grips of the clamps 23 around the dovetail-shaped top of the interconnecting plate 22. and the brake ring 21. The brake ring 21 is intended to abut an upper surface of the submarine when the submarine 10 is fully salvaged, in order to provide a support tray for the submarine 10 legs against the actively operated gimbal joint. The biasing elements 24 are passive and are intended to limit any sway of the submarine 10 and the brake ring 21 when suspended from the lock case 18. The biasing elements 24 may be telescopic cylinders with an outer housing and a piston extending from the outer housing. A biasing element {not shown) is positioned inside the outer housing and biases the piston outwardly relative to the outer housing. FIG. 3 is a sketch of a possible lavout of an electrical system for an apparatus for launching and salvaging a submarine from / to an offshore site such as a ship.
