Definitions

  • the primary anchoring member described above can be used on an entire vessel wall or only in localized portions of the vessel wall such as the ballast zones.
  • the vessel wall has a vertical component defining a height of said vessel wall in the direction of earth's gravity, the vessel wall comprising several of said primary anchoring members each comprising a base, a rod, a support element, a sealing washer and a deformable gasket as above, said several primary anchoring members being arranged on a lower portion of the vessel wall, for example at least the lower two thirds of the height of said tank wall.
  • the vessel wall is a first vessel wall, the vessel further comprising a second vessel wall, the first vessel wall and the second vessel wall forming an edge of the vessel, the first vessel wall tank comprising several of said primary anchoring members each comprising a base, a rod, a support element, a sealing washer and a deformable seal as above, said several primary anchoring members being arranged at a distance of the edge of the tank lower than a predefined threshold.
  • the predefined threshold corresponds to the width of five insulating panels, said several primary anchoring members being for example arranged to retain five successive primary insulating panels in a direction perpendicular to the edge.
  • Primary insulation panels can be made in various ways. According to one embodiment, the primary insulating panels are parallelepipedic in shape.
  • the deformable seal is completely housed in the protective portion of the bell.
  • the deformable seal is protected by the bell, for example during assembly operations of the primary anchoring member in the vessel.
  • the deformable seal is fixed on the rod between the passage of the mounting portion of the bell and the sealing washer.
  • the bellows is of flared shape, the second axial end of the bellows fixed to the sealing washer having a circumferential dimension greater than the circumferential dimension of the first axial end of the bellows fixed to the rod.
  • the secondary insulating barrier comprises an anchoring plate, the base of the primary anchoring member being anchored to said anchoring plate.
  • the anchor plate is housed in a recess formed in the cover plate of a secondary insulating panel, the anchor plate having an internal surface flush with the internal face of the cover plate.
  • the anchor plate comprises a threaded orifice and the base has a threaded outer end, the base of the primary anchor member being anchored onto the anchor plate by screwing the threaded end of the base into the threaded hole in the anchor plate.
  • an inner end of the rod opposite the base is threaded
  • the primary anchoring member further comprises a nut screwed onto said threaded inner end, the support element being interposed between said nut and the base of the primary anchor member.
  • the deformable gasket is inserted between the bearing element and the sealing washer.
  • the bell has freedom of movement along the thickness direction of the vessel wall.
  • the freedom of movement of the bell is limited on the one hand by the nut mounted on the rod, or if necessary the elastic washer(s), and, on the other hand, by the surface of anchor shoulder anchor.
  • the transfer wedge has a thickness, taken along the thickness direction of the vessel wall, less than the thickness of the bottom plate of the primary insulating panel.
  • the transfer wedge further comprises an internal portion developing from the plate and surrounding the bell.
  • the transfer spacer is smaller in size than the spacing available between the panels. The assembly of the wedge between the panels is thus facilitated.
  • the terms “external” and “internal” will be used to designate, according to the definitions given in the description, the relative position of one element with respect to another, with reference to the interior of the tank.
  • an element close to or facing the interior of the tank is qualified as internal as opposed to an external element located close to or facing the outside of the tank.
  • the expressions “radially on the periphery” or “radially external” characterize the portion remote from an axis defining a circular element, as opposed to the expression radially internal which characterizes the portion close to said axis.
  • the expression “transverse” is used to qualify a displacement or a direction of development of an element according to a direction situated in a plane perpendicular to the direction of thickness of the vessel wall.
  • the wall of the tank comprises successively, in the direction of the thickness, from the outside towards the inside of the tank, a secondary thermally insulating barrier, hereinafter secondary insulating barrier 1, retained on a load-bearing wall (not illustrated), a secondary waterproof membrane 2 resting against the secondary insulating barrier 1, a primary thermally insulating barrier, hereinafter primary insulating barrier 3, resting against the secondary waterproof membrane 2 and a primary waterproof membrane 4 intended to be in contact with the gas natural liquid contained in the tank.

Such relaxation slots 20 have the function of preventing deformation or degradation of the primary insulating panel 11 due to the differential contractions between the cover plate 15 and the primary insulating gasket 14. Such relaxation slots 20 also make it possible to let corrugations 21 work and thus avoid creating stresses in the primary waterproof membrane 4 and in the primary insulating barrier 4 in the case of a primary waterproof membrane 4 comprising undulations 21 as described below.
  • the recess 23 has an inner section 24 having a first diameter and an outer section 25 having a second diameter.

  • the bellows 42 having a flared shape, the outer axial end of said bellows 42 is fixed on a radially outer peripheral edge of said inner surface 38.
