  • the main object of the present invention is to propose a sealed and thermally insulating tank of the kind defined above which makes it possible to reduce heat losses.
  • a sealed and thermally insulating tank is characterized in that, in a manner known per se, the insulating barrier is formed by means of boxes containing a particulate thermal insulator, these boxes being substantially parallelepiped and comprising interior partitions, and that the radiation reflecting elements comprise sheets covering the flat surfaces presented internally by the boxes, and the walls of said interior partitions.
  • each elementary cell of a box is provided with a reflective face, which makes it possible to benefit from multireflection by means of screens generally orthogonal to one another.

  • a methane tanker as described in French Patent No. 2,527,544, comprises tanks whose outer wall 1 is formed by the double hull of the ship.
  • there are plywood slats on this wall which rest on strands of polymerizable resin and the positioning of these slats 2 is adjusted so that they define, in a discontinuous manner, a theoretical surface independent of the more or less good conformation of the wall 1.
  • each element consists of a rectangular plywood box of 1.2 meters by 1 meter and internally has supporting struts 4, which are all parallel to the long side of the box.
  • the spacers 4 are interposed between the two large faces of the box, one of these large faces resting on the slats 2.
  • non-load-bearing spacers 5 have been put in place, which are only intended to ensure the relative positioning of the spacers 4.
  • the non-supporting spacers 5 are made of plastic foam; each tank 3 is 25 cm thick and has five load-bearing spacers 4 and three non-load-bearing spacers 5.

  • retaining members made up of studs 8 welded to the load-bearing structure 1 of the ship, these studs 8 comprising a threaded end with which cooperates a nut which rests on a square plate.
  • the boxes 3 are in abutment against one another along their faces perpendicular to the alignment of studs 8, but, in the perpendicular direction, the boxes 3 are spaced by a joint zone where the battens 7 and the members of detention. After all the retaining members have been screwed on, the joint zones are blocked by the plastic shims 9, these shims having longitudinal slots, which allow their insertion with elastic clamping in the joint zones.
  • the parts of the joint zones which are not filled by the shims 9 can be filled with glass wool.
  • the secondary insulation barrier comprises, above this second layer, which has just been described, a first layer consisting of boxes each designated by the reference 10 as a whole.
  • the set of boxes 10 rests directly on the set of boxes 3.

  • each box 10 there are, parallel to the short sides, seven equidistant carrier spacers 11 and parallel to the long sides, three non-carrier spacers 12.
  • the carrier spacers 11 are plywood plates inserted between the two large faces of the box 10.
  • the non-supporting spacers 12 are made of plastic foam and have the same role as the spacers 5 previously described.
  • the retainers of this first neck che of the secondary insulation barrier are constituted by rods 15, the base of which is screwed into a socket 8 welded to the support structure 1 of the ship.
  • plastic shims are inserted which have longitudinal slots so that they can be inserted by elastic compression in the joint zones and then be held there by elastic blocking.
  • These shims have longitudinal grooves having the same role as the grooves of the shims 9.
  • the parts of the joint zones of this first layer, that they are not occupied by the shims of insulating plastic material, can advantageously be stuffed with wool of glass to improve insulation.
  • the secondary sealing barrier which is constituted by invar strakes 16 with raised edges is put in place.
  • These strakes 16 are arranged between two consecutive weld wings 14: they have a width of 50 cm; the welds are made on either side of the wings 14 continuously to ensure sealing.
  • the wings 14 retain the secondary sealing barrier on the caissons 10.
  • the bearing surface of the secondary sealing barrier is continuous even at the level of the joint areas between the caissons 10 due to the presence of shims in particular.
