Definitions

  • the present invention relates generally to sealed enclosures for underwater containment of various types of equipment.
  • the depths reached can reach or even exceed 3000 meters.
  • Submerged devices are usually placed in a sealed envelope to protect their internal components from seawater.
  • the enclosure is filled with a non-electrically conductive liquid, usually dielectric oil, and balanced in pressure with the sea.
  • a non-electrically conductive liquid usually dielectric oil
  • the equipment placed in the enclosure is then subjected to the pressure of immersion, and must also be compatible with the oil.
  • the walls of the enclosure do not undergo the stress related to pressure, and therefore do not require to be made with increasing thickness with the immersion depth.
  • the enclosure is filled with a gas (air, nitrogen ...) at low pressure, generally close to atmospheric pressure.
  • a gas air, nitrogen
  • the walls of the enclosure are sized to resist the immersion pressure.
  • the equipment is then installed in conditions similar to those of an industrial use.
  • the present invention relates to the second type of enclosure, called "at atmospheric pressure"
  • the thickness of the enclosure must increase as the immersion depth increases, depending on the pressure to be withstood.
  • the sealed enclosures for the underwater containment of an apparatus are made from a cylindrical envelope comprising two end domes.
  • the thickness of the cylindrical envelope can reach 80 mm so that, for an envelope having a length of 7 m and an internal diameter of 2 m, the mass total envelope including the materials it contains can reach or exceed 40 tons, which requires significant lifting means.
  • a sealed enclosure for the underwater containment of an apparatus comprising a set of ellipsoidal modules juxtaposed in a sealed manner and internally defining at least one receiving volume of the apparatus.
  • the sealed enclosure comprises a hemispherical dome-shaped removable end module connected to said set of modules by a sealed flange.
  • the ellipsoidal modules are connected two by two by cylindrical connectors.
  • These cylindrical connections may have a thickness greater than that of the ellipsoidal modules.
  • the cylindrical connectors are equipped with stiffening elements.
  • these stiffeners are formed by a localized enlargement of the cylindrical connectors.
  • FIG. 1 illustrates the general architecture of a sealed enclosure for the underwater containment of an apparatus according to the invention, designated by the general reference numeral 1.
  • the sealed enclosure is shown in a supposed vertical position.
  • this enclosure is intended for the protection of one or more submerged electrical or electromechanical devices, such as a variable speed drive, a high voltage or low voltage distribution equipment, a power supply system , ...
  • a submerged electrical or electromechanical device such as a variable speed drive, a high voltage or low voltage distribution equipment, a power supply system , ...
  • the enclosure 1 comprises a set of ellipsoidal modules 2, 3 and 4, here the number of 3, arranged in the extension of each other and connected in pairs by cylindrical portions 5, 6 and 7.
  • the envelope comprises a dome 8 shaped truncated sphere sealingly connected to one of the ellipsoidal modules and, at the opposite end, a dome 9 hemispherical connected to the other module 2 ellipsoidal end.
  • the ellipsoidal modules and the end domes jointly delimit an internal volume filled with nitrogen at atmospheric pressure and intended to receive the apparatus to be immersed.
  • the number of modules is not limiting and can be chosen according to the size of the equipment.
  • each of the ellipsoidal modules has a flattened sphere shape and is more particularly formed by the spherical zone of a flattened sphere between two parallel planes such as P1 and P2.
  • the modules and the end domes 8 and 9 have a reduced thickness relative to the thickness of a cylindrical shell necessary to withstand the immersion pressure.
  • the thickness of the spherical wall is of the order of 50 mm.
  • cylindrical connectors 5 and 6 have an increased thickness determined to ensure the stiffness of the assembly, for example of the order of 150 mm.
  • the diameter of the hemispherical dome 9 is smaller than the internal diameter of the cylindrical connectors 5, 6 and 7 and chosen to be greater than the largest transverse dimension of the apparatus so that after introduction of a device through the opening of the end ellipsoidal module 2, no problem of inserting the device into the rest of the enclosure can not occur.
  • the hemispherical dome 9 is actually a removable element and is attached to the hemispherical module 2 by means of a flange 10.
  • cylindrical connections 5, 6 and 7 can be provided with a stiffener, such as 11, made in the form of a thickening of localized material.
  • a stiffener 11 remains however optional and has been illustrated only for one of the cylindrical connectors.
  • the sealed enclosure which has just been described which uses a set of juxtaposed ellipsoidal modules makes it possible to considerably reduce the thickness of the enclosure, at the location of the ellipsoidal modules.
  • the weight gain can reach about one third compared to cylindrical enclosures.
