Definitions
- the present invention relates generally to sealed enclosures for underwater containment of various types of equipment.
- Such industries require for example to immerse at great depth ESP (electro-submersible pump) electropumps, as well as their power supply system.
- ESP electro-submersible pump
- 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 an electrically nonconductive liquid, generally dielectric oil, and balanced in pressure with the sea.
- the equipment placed in the enclosure is then subjected to the pressure of immersion, and must also be compatible with the oil.
- the pressure is balanced, the walls of the enclosure do not undergo pressure stress, and therefore do not require to be made with increasing thickness with the depth of immersion.
- 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 dimensioned 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 depth of immersion 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 sealingly and internally defining at least one volume of reception of the apparatus. It has been found that the realization of a sealed enclosure by means of juxtaposed ellipsoidal modules allows a gain of the order of one third of the total mass, with respect to a cylindrical envelope.
- the sealed enclosure includes a hemispherical dome shaped removable end module connected to said module assembly by a sealed flange.
- the ellipsoidal modules are connected in pairs 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 loosely extending the cylindrical connectors.
- FIG. 1 is a side view of a sealed enclosure according to the invention.
- Figure 2 is a partial sectional view of the enclosure of Figure 1.
- FIG. 1 illustrates the general architecture of a sealed enclosure for the underwater confinement 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 immersed electric or electromechanical devices, such as a variable speed drive, a high voltage or low voltage distribution equipment, a power supply system that is backed up. , ...
- immersed electric or electromechanical devices such as a variable speed drive, a high voltage or low voltage distribution equipment, a power supply system that is backed up. , ...
- the enclosure 1 comprises a set of ellipsoidal modules 2, 3 and 4, here three in number, arranged in the extension of each other and connected two by two 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 PI 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 may 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.
