- Figure 28 is a schematic cutaway representation of a tank LNG tank and a loading / unloading terminal of the tank.
- FIG. 1 a wall of a sealed and thermally insulating tank is shown.
- the general structure of such a tank is well known and has a polyhedral shape. It will therefore focus only to describe a wall zone of the tank, it being understood that all the walls of the tank may have a similar general structure.
- the wall of the tank comprises, from the outside to the inside of the tank, a supporting structure 1, a secondary heat-insulating barrier 2 which is formed of heat-insulating boxes 3 juxtaposed on the supporting structure 1 and anchored thereto by secondary holding members 4, a secondary sealing membrane 5 carried by the boxes 3, a primary heat-insulating barrier 6 formed of heat-insulating boxes 7 juxtaposed and anchored to the secondary sealing membrane 5 by primary retaining members 8 and a primary waterproofing membrane 9, carried by the boxes 7 and intended to be in contact with the cryogenic fluid contained in the tank.
- the supporting structure 1 may in particular be a self-supporting metal sheet or, more generally, any type of rigid partition having suitable mechanical properties.
- the supporting structure may in particular be formed by the hull or the double hull of a ship.
- the carrying structure comprises a plurality of walls defining the general shape of the tank.
- the primary 9 and secondary 5 waterproofing membranes are, for example, consist of a continuous sheet of metal strakes with raised edges, said strakes being welded by their raised edges on parallel welding supports, fixed on the lid of the boxes 3 7.
- the metal strakes are, for example, made of Invar ®: that is to say an alloy of iron and nickel whose expansion coefficient is typically between 1, 2.10 "6 and 2.10 " 6 K ⁇ 1 .
- the boxes 3 of the secondary thermally insulating barrier 2 and the boxes 7 of the primary thermally insulating barrier 6 can equally well have identical or different structures and equal or different dimensions.
- the box 3, 7 has substantially a rectangular parallelepiped shape.
- the box 3, 7 has a bottom panel 10 and a cover panel 11 parallel.
- the bottom panels 10 and cover 11 are, for example, made of plywood.
- the cover panel 11 has, on its inner face, grooves 12 for the housing of the welding supports metal strakes of waterproofing membrane.
- a plurality of spacers are interposed between the bottom panel 10 and the cover panel 11, perpendicular to them.
- the plurality of spacer elements comprises, on the one hand, two opposite lateral walls 12, 13, and, on the other hand, a plurality of carrying webs 14.
- the carrying webs 14 are arranged parallel to each other between the two side walls 12, 13, in a direction perpendicular to said side walls 12, 13.
- Compartments 15 for housing a heat-insulating lining are provided between the carrying sails 14.
- the heat insulating lining may be made of any material having appropriate thermal insulation properties.
- the filling insulation is selected from materials such as perlite, glass wool, polyurethane foam, polyethylene foam, polyvinyl chloride foam, aerogels or others.
- the carrier webs 14 are wavy and oscillate on either side of their longitudinal general direction. Each corrugation thus extends along an axis perpendicular to the bottom panels 10 and cover 11. In the embodiment shown, the corrugations are substantially sinusoidal. However, other forms of undulations are also possible. For example, the corrugations may in particular have shapes of triangular teeth or rectangular crenellations. Due to their shape, such corrugated carrier webs 14 have a high buckling resistance without the need to give them much thickness. It should be noted that if corrugations having a periodic structure make it possible to ensure good uniformity of the compressive strength, it is also possible to provide non-periodic corrugations in order to meet certain localized mechanical requirements.
- FIGS 3 and 4 illustrate a carrier web 14.
- the carrier web 14 has flanges 16a, 16b distribution of loads.
- the upper flange 16a has a flat surface intended to face the cover panel 11 while the lower flange 16b has a flat surface which is intended to face the bottom panel 10.
- flanges 16a, 16b have a width which is greater than the thickness of the wall of the carrier web 14 in its main part, extending between the two flanges 16a, 16b.
- the load distribution flanges 16a, 16b prevent stress concentration on a particular area by providing a greater support surface between the carrier web 14 and the bottom panels 10 and cover 11.
- the distribution flanges loads may have a parallelepipedal shape, as shown in Figures 3 or 4.
- the width of the flanges 16a, 16b may be equal to the amplitude of the corrugations.
- the load distribution flanges 16a, 16b may themselves have corrugations.
- the carrier webs are made of composite material comprising a thermoplastic matrix reinforced with glass fibers. A method of manufacturing the carrier webs 14 is described in connection with FIGS. 5 and 6.
- thermoplastic resin 19 is based on polypropylene.
- Such plates have a composite structure comprising a thermoplastic matrix and a mat or fiberglass felt.
- Such composite structures are designated by the acronym GMT, for "glass fiber mat reinforced thermoplastics" in English.
- the plates of composite material are shaped, as shown in FIG. 5.
- the plates of composite material are heated in an oven 20, then placed in a mold 21 in which they are going to be shaped by applying pressure.
- the carrier webs thus formed are then cooled.
- the carrier webs 14 are thus shaped by thermocompression, by heating the composite material plates and then stamping them on the press.

- the carrier webs 14 are fixed by hooks 38, one curved end of which cooperates with the soles carrying sails to retain the carrier webs against the bottom panels 10 and cover 11.
- the hooks 38 are elastic hooks for attachment by "clipping" elastic.
- the hooks 38 are rigid and are immobilized in a retaining position of the carrier web 14 by means of wedges 39 made of wood that can be introduced through the bottom panel.
- FIG. 18 shows an embodiment in which the retaining hooks 38 each comprise two jaws 39, 40 placed, in the direction of thickness of the tank, on either side of a tongue 41 projecting laterally from the veil. carrier 14.
- the carrier web 14 is fixed to the bottom panel 10 or the cover panel 11 via a fastener 42 having a cylindrical rod carrying at both ends heads having a larger diameter. wide than that of the cylindrical rod.
- the carrier web 14 carries a metal part provided with an oblong hole 43 having a small dimension greater than the diameter of the cylindrical rod and smaller than the diameter of the heads, said oblong hole 43 being extended by a circular orifice 44 having a larger diameter than the of the head of the fastener 42.
- the bottom panel 10 or lid 1 1, vis-à-vis, has an oblong hole 45 extended by a circular orifice 46.
- association oblong hole 45 and circular orifice 46 of the panel 10, 11 is arranged, head to tail, with respect to the combination of elongate hole 43 and circular hole 43 fitted to the carrier web 14.
- the circular holes 44 are made to coincide. , 46 carried respectively by the carrier web 14 and the bottom panel 10 or cover 11 to allow passage of a head of the fastener through the panel 10,
