    A modular offshore hydrocarbon production, storage, and loading system, which includes an assembly of cylinders rigidly connected together, with the cylinders including at least one metal floatation cylinder adapted to occupy a vertical position in use. A bottom of the cylinder is situated below a level of the water and a floatation cylinder surrounded by several metal peripheral cylinders which descend below the floatation cylinder and define, with the bottom of the floatation cylinder, a free space for accommodating at least one member for rigidifying the system. The peripheral cylinders include metal oil storage cylinders, with the storage being effected on a water column communicating with the water surrounding the system, and metal ballast cylinders or parts of cylinders filled with oil, water, air or inert gas.

    The invention relates to modular CHCteMe, in particular, used for the production, storage and / or loading of hydrocarbons in a coastal region.
    Oil from the coastal shelf is typically produced from production platforms connected to the shore through oil pipelines. If production at a field is insufficient by quantity or duration for depreciating the cost of the pipeline connecting the platform to the shore, a production platform and storage at sea should be provided.
    The purpose of the invention is to increase the reliability of the floating modular device.
    Figure 1 shows schematically a set of modular device in a vertical position in water; Fig.2 device, top view; on fig.Z - section aa on fig, 1; in fig. section BB in figure 1; Figures 5-8 illustrate methods for transporting and installing the modular device in place; figure 9 - the connection of metal cylinders by welding; Fig. 10 is a peripheral cylinder in which the ballast chamber is located above the storage chamber; in figure 1 to 12 - pergorodka in metal cylinders; on Fig - modular device, isometric.
    A floating modular device for extracting, storing and loading oil into the sea, coming from subsea wells (not shown), contains a set of rigidly connected cylinders. These chains contain in combination: at least one central floating metal cylinder








     one
    in the operating mode, occupying a vertical position (Fig. 1), while the lower part of this cylinder is located below the water level 1. The upper part 2 of cylinder A protrudes above the water level and carries a bridge or platform 3 with production equipment and livelihood equipment containing production equipment and equipment for life support and livelihoods. This overhang of cylinder A constitutes the terminal point to which the oil tankers moor, making shuttle flights between this terminal point and the coast.

    The central floating metal cylinder A is surrounded in a circular arc, at least by a crown, of rigidly connected by welding and connecting elements and arranged around a vertical axis along the circular arc of the peripheral metal cylinders Aj, A, ..., which are installed below the water level and communicated with her. At this location, under the floating cylinder A, a free space B is formed (figure 4), limited by the crown of the peripheral
    5 cylinders AJ, A, ... If necessary, this free space can be used to install organs in it that can increase the rigidity of the system, or to place any ballast or an additional cylinder.
    The peripheral meta cylinders contain oil storage cylinders, and their filling is carried out
    5 on the water column communicated through the pipe 4 with the water surrounding the device. Oil floats on water, as the hydrostatic column oil + water is in equilibrium with the surrounding water. Under these conditions, the water level in cylinders such as cylinders A is lowered or raised depending on whether the oil is being accumulated or recovered. Used worker 35
    SRI cylinders A, fully stored
    located below the level of the surrounding water. In order to avoid contamination of seawater with oil, a sufficient gap is provided in the lower part of the storage cylinders and a security system that prevents a decrease in the level of oil below a set limit. Water contaminated with oil may be subject to appropriate
    physico-chemical treatment before going out to sea or may remain in the siphon or in the buffer cylinder. Peripheral metal cylinders also contain ballast metal cylinders or ballast parts of metal cylinders filled with oil, water, air, or an inert gas.
    Floating cylinders or cylinders can be mounted among storage cylinders and ballast cylinders arranged, if necessary, in a circular arc. Such a structure may form a complete crown.
    (Fig.13). On Fig shows a bridge directly connected to the floating cylinders. The bridge (platform) can be pivotally connected to at least one floating cylinder and / or to storage cylinders or to ballast cylinders using connecting supports 5. In addition, part
    floating cylinders or cylinders can essentially be carried out for storage or for ballasting. To increase the stiffness, crosses or stiffeners can be installed in the center of the rim.
    Some of the peripheral cylinders AJ ,, AJ, ... (Figs. 10-12) may have an internal partition 6 or 7 welded to the wall 8 of the cylinder either directly or with the help of part 9. This internal partition 6 or 7 limits the ballasting camera located above storage chamber S.
    The crown of the cylinders A, A, ... can be stored rigidly attached by welding to the floating cylinder A at height h, less than the height H of this cylinder A, (since cylinders A.
    3
    located below the cylinder
    A), but constituting at least 25% of N.'s height.
    A connecting element 10 can be included in the wall 8 of each cylinder (A, A., AJ, ...) during the manufacture of this wall, while the connection of two adjacent cylinders is carried out by welding the connecting elements with which these cylinders are equipped (Fig. 9). ).
    Another option for joining cylinders is to replace two segments of element 10 with one segment.
    The proposed device is fixed at the chosen place with the help of appropriate means with the use of chains or cables connected to the crust or fixed objects, or with the use of cables, or by means of axial fastening.
    A torch support designed for burning gas can be mounted on a bracket hanging from one side of the platform, or float on water at a certain distance from the system, connecting to the last flexible pipeline, and since the tanker performing shuttle flights , should approach and move freely around the production system, the stand for the torch, the bridge for helicopter landing and the berthing point of the tanker are mounted on the turntable (T) (Figures 2 and 6), and the distance between these three types borudovaniya should vyderzhivats constant.

    by efficiently towing a set of cylinders (figure 5) and a floating bridge, for example, using barges 11 and 12 (figure 6). Through the ballasting of some cylinders, the set of cylinders is tilted to a vertical position. Then the remaining horizontal bridge and the set of cylinders are connected in a vertical position, in connection. For this purpose, the bridge and the set of cylinders are connected by means of such devices, which in place allow them to be connected and disconnected.
    The bridge or platform (Fig. 7) is connected to the floating cylinder by means of at least one hinge connection, which allows the production kit and the bridge to be transported in a horizontal position; after disconnecting the connecting elements, this transportation to the selected place is carried out by towing over the surface water.
    Throughout this transportation, the platform is in the horizontal position by ballasting and / or using cables, diagonals or jacks connecting this platform to the cylinders.

    When the system comes to the chosen place, the set of cylinders A ,,
    A., A,
    . , .T.J, ... tilts to a vertical position, and the bridge remains in a horizontal position. The connecting elements are then connected (Fig. 8).
    The modular device contains adjustment means to compensate for changes in the buoyancy of the system depending on changes in the water-oil level in the storage cylinders (Fig. 1). The difference in density between water and oil is played in changing the volumetric weight of the system in water.
    during filling or emptying of storage tanks.
    In order to avoid corresponding changes in the draft, which can interfere with the loading of oil tankers and disrupt the static stability of the system, the latter can be equipped with sensors for changing the level of the oil-water interface in storage tanks, and these sensors control the inlet or outlet of oil or water or inert gas, or air in the ballasting chambers of B.
