专利说明:
The invention relates to hydraulic structures and relates to a method and apparatus for producing large bodies of ice for use, for example, as bases for structures for drilling or production equipment in offshore oil production such as breakwaters, wharves, for large bulk works and t .P. The aim of the invention is to reduce the time required for the construction of large ice bodies. FIG. Figure 1 shows an ice body at the initial stage of its production, a longitudinal section; in fig. 2 - ice body obtained by the proposed method and intended for use as a drilling or advanced platform, longitudinal section; option; in fig. 3 is an ice body obtained by the inventive method when a drilling rig is placed between two ice bodies, a longitudinal section, the second embodimentJ in FIG. 4 shows an apparatus for producing an icy body, top view. . Floating waterproof formwork 1, consisting of the bottom 2 and the surrounding side walls 3, was installed; they were built in a quiet bay of a fjord. The formwork cage is made of wood or metal, and isopores are used as the insulating material. As the ice body 4 is produced, the walls can be extended with the help of connecting elements 5. Water freezing is done in several ways. Fresh water from a river or a large lake in the vicinity is supplied to one or several ice-producing plants that receive ice flakes, ice cubes, etc., which are fed in an even flow through nozzles 6 into the mold. Together with the ice flakes supplied from the nozzles 6, the water with the lowest possible temperature is sprayed through the nozzles 7. The ice flakes from the freezer have such a low temperature that the water between them I.PI ice cubes freezes into solid ice. Instead of ice, flakes or pieces of a freezer can produce ice lashes that can be twisted in tight spirals one over the other. To cope with the iceberg, the outer surfaces must be insulated by isolating 0 five 0 five 0 five 8. Above the WATER surface, the insulation may consist of wired fiberglass or filler mats with a protective or reflective surface, but may also consist of lashes of these materials, which are wound as part of a specified helix. At greater depths in the sea, due to the increased pressure, the insulation should be positioned in a slightly different way than above the surface of the water, for example, using one or more skirts of highly reinforced foil. The water in the skirts has an insulating effect, and direct contact between the ice surface and the water jets is eliminated. This method can be used in combination with the winding method, with the skirts being unwound gradually as the completed ice body sinks into the sea. Skirts supply with cargo. In order to remove the heat that penetrates the insulation, it is necessary to place the cooling elements 9 at some distance inside the insulation along the outer surfaces of the body. These may be cooling tubes that are part of these spiral turns. The cooling effect can be monitored automatically according to the temperature readings, which are continuously obtained using temperature sensors frozen in and distributed over the ice. When ice is produced, a large amount of heat is generated. This heat can be used as heat for nearby buildings or for the intensive cultivation of fish or mussels (oysters). Heat can serve as the basis for power plants operating on temperature differences (cold water of the fjord with respect to the resulting 6bfTKy heat). For the convenience of transporting ice on the sea from the place of destination to the destination, its vertical height and, thus, the draft should not be too large so that the body displacing so much water can pass over the smallest tow points. At the destination, the vertical height can be increased so that the body is at rest on the seabed. and could withstand all the forces of currents, waves, wind, etc. The planned installation of equipment on an ice body, which cannot be done on shore, can be carried out at the destination. On the upper surface of the ice body, buildings 10 and other structures such as a drilling rig 11 can be erected. If the ice body needs to be used as an oil production platform, valves can be installed on its surface, pumping equipment for loading tankers, etc. build a helipad 12 or a short runway, since the ice body can be very large in the horizontal direction compared to offshore platforms. If the ice on the structure is at a depth of about 100 m, then it can have a diameter of about 250 m. Staff rooms, production facilities 13, and also warehouses 14 can be positioned inside the ice mass in the same way as in the Antarctic stations. In this case, they are protected from the weather and wind. Large ballast tanks, such as warehouses 14, can also be used to increase body draft at the destination. If a large storage facility of warehouse 14 is cut in ice at the place where it was received, for example, on the coast, then this gives the ice body a smaller draft compared to a solid ice body of the same size. Warehouse space 14 can be made so large that the ice body swims over the smallest places along its towing route. At the destination of the premises under warehouses 14, it can be filled with supercooled water, such as salt water, having a higher salt content, so that the liquid remains in a liquid state at temperatures from about -5 to -8 ° C. The draft of the body increases, the body exerts a somewhat greater pressure on the seabed and will acquire sufficient stability. In storage tanks 14, it is also possible to store oil or liquefied gas. If the storage rooms of the warehouses are not filled with oil, they can be filled with sea water if necessary to give the ice body a sufficient weight. Direct access to the seabed can be provided by arranging the internal cavity 15, which extends from the upper part of the ice body down to the bottom. If the body is compacted with respect to the external pressure of the water by creating the surrounding skirt 16, which is pressed into the seabed under the influence of a large ice body weight, then a drilling hole 17 can be installed in the cavity 15 or direct access to the upper part of the well may be provided. Thus, it is possible to provide the same conditions as on the ground for drilling and oil production. Heavy constructions, such as building 10 or drill 11, can cause undesirable ice creep. Sliding may be greatest in a zone near the surface of the water, because there is no opposite pressure from the outside, or it is too small. Therefore, supports 18 are installed for such structures of buildings to a certain depth below the surface of the water, to a level where the tendency for ice to slide is minimal. At this level, the bases are located on the load sharing plates 19. To prevent water leaking under the skirt 16 and its penetration into cavity 15 in the ice body, at least in its lower part, the temperature is maintained so low that the seabed freezes to a sufficient depth. When ice is exposed to high pressure, it becomes semi-fluid and slips occur in it. To prevent this, an ice body at least in the zone around the surface of the water is obtained inside the form: 20 (Fig. 4). This shape may consist of two concentric rings 21 and 22, and the inner ring 21 is so elastic that it resists, but moves with the landslide. This ring is also equipped with fasteners in the form of radially directed zat 23, which are rigidly frozen in ice. The outer ring 22 is a hard, rigid ring, and compressed gas is fed into the space 24 between the two rings, with which ice can be controlled to creep. The outer ring is so heavy that it can slip over the body. In order to improve this on They install buoyancy tanks or make the ring slightly conical in shape so that an upward force arises as a reaction to the sliding of ice. Since ice creeps mainly on the surface of the water, in an area where there is significant erosion under the action of waves, isolated concrete cassettes can be used, which are pressed to the ice surface with steel cables passing from the cassette to the cassette around the whole body. In this way, a breakwater effect is obtained, and at the same time technical isolation and creep resistance are provided. In addition, granulated material such as sand, sawdust or the like can be frozen into ice to reduce creep. Granular material of this type in combination with temperature control reduces the creeping tendency and, depending on the situation It can act as a ballast, or as an additional means of buoyancy according to the density of the chosen material, greater or less than ice. The invention makes it possible to obtain ice bodies of various densities, for example, in a vertical plane, with the lower part giving a relatively higher density than the top, which favorably affects the stability and allows to increase the height in relation to the width, which would be difficult to dry; In addition, ice bodies can be obtained, which are entirely submerged in the sea, and can serve, for example, as permanent bases for drilling and production platforms at large ocean depths near polar regions. The method can also be used to create artificial horns in fiords or narrow bays. P t / a.J FIG. VNIIPI Order 1336/62 Circulation 641 Subscription Branch of PPP Patent, Uzhgorod, Proektna St., 4
