- this multilayer structure comprising one or more sealed membranes and one or more thermally insulating barriers interposed between the carrier wall and the sealed membrane or membranes.
- the thermal leakage existing through the tank wall typically brings the interior surface of the carrier structure to a temperature below the ambient temperature of the atmosphere. If humidity-laden ambient air could penetrate into the interior space of the supporting structure, and especially between the supporting structure and the tank wall, this low temperature favors a condensation and water-streaming phenomenon. the inner surface of the supporting structure.

- the protruding flange 10 is interrupted only at two drainage holes 11, which are located near the rear transverse wall 5 in the example shown.
- the projecting flange 10 has a rectilinear portion 101 which extends continuously along the front edge of the bottom wall 2, two straight portions 102 and 103 which extend continuously along each of the two edges sides of the bottom wall 2 and whose front ends are connected continuously to both ends of the straight portion 101, and a straight portion 104 which extends along the rear edge of the bottom wall 2, both of which ends are continuously connected to the rear ends of the two straight portions 102 and 103.
- the rectilinear portion 104 is interrupted twice in this example.
- the protruding flange 10 has the overall shape of a rectangular frame. This shape can be modified, in particular with rounded portions at the corners of the bottom wall 2.
- the main function of the projecting flange 10 is to guide the runoff water in the marginal zone 15 to the drainage orifices 11, and thus to prevent this runoff from migrating to the central portion 14 of the bottom wall 2.
- Each drainage orifice 11 passes through the bottom wall 2 in its thickness and opens into a drainage pipe 12 for driving the drained liquids to an evacuation system, not shown.
- the protruding flange 10 is here interrupted on the edges of the two drainage orifices 11.
- each drainage orifice 11 can collect both liquids coming from the marginal zone 15 and liquids coming from the central zone 14 of the wall. bottom 2 located on the other side of the protruding flange 10.
- the ship's ballasts may be filled in such a way as to tilt the hull of the ship with a slope directed towards the rear, which leads to the accumulated liquid in the marginal zone 15 of the bottom wall around the protruding flange 10 to flow by gravity to the drainage holes 1 1 located in the rear portion of the vessel.
- a first embodiment is shown in Figures 2 and 3.
- the protruding flange 10 is here formed of elongated metal parts 20 welded to the bottom wall 2.

- An insulating block 21 or 22 each incorporates a secondary insulating barrier element 23, a secondary watertight barrier element 24 and a primary insulating barrier element 25.
- the insulating blocks 21 and 22 can be fixed to the supporting structure in different ways , by gluing and / or using mechanical fasteners, for example studs and nuts.
- the insulating corner block 22 comprises two bent wings at an angle equal to the angle between the bottom wall 2 and the adjacent side wall, namely 135 ° at the edge 29 between the bottom wall 2 and the lower chamfer portion 6 in Figure 2, and 90 ° at the edge 28 between the bottom wall 2 and the rear transverse wall 5 in Figure 3.
- the projecting flange 10 is arranged each time between a row of insulating corner blocks 22 which covers the edge 28, 29 and a row of flat insulating blocks 21 which rests on the bottom wall 2 next to the row of the blocks. angle insulators 22.
- the metal parts 20 thus provide a positioning stop for the face end of the wing of the insulating block of angle 22 which rests on the bottom wall 2, which facilitates the introduction of the insulating blocks of angle 22.
- a bead of polymerizable resin 27, for example epoxy mastic, can be arranged along the side of the metal parts 20 facing the insulating corner blocks 22, to precisely adjust the position of the insulating blocks 22 with respect to the metal parts 20.

- Putty is a pasty material consisting of an epoxy resin and a hardener that hardens the sealant after deposition. Putty is deposited on the face of insulating blocks intended to be opposite the load-bearing structure. Before the sealant has hardened, the insulating blocks are put in place. The putty crushes during this setting up. Rigid shims, shown at 34 in FIG. 11, may be placed on the bearing wall to control the final thickness of the sealant and to ensure the flatness of the surface of the insulating blocks placed on the same wall. carrier.
- the angle structure 22 may be formed of two parts secured together, namely a main portion 32 and an attached portion 33 which extends parallel to the ridge along the outer face of the main portion 32 turned away from the ridge.
- the added portion 33 has the shape of an elongate parallelepiped block of the same thickness as the main portion 32 and fixed by gluing or other means against the outer face of the main portion 32. Its width can be fixed to measure, to take account of dimensional tolerances of the bearing wall.
- the polymerizable resin bead 30 can be arranged under the insert portion 33 of the corner structures 22. This facilitates the mounting of the polymerizable resin bead 30. More specifically, the mounting of the corner structures 22 begins with the placing the main portions 32, without the portions 33. The corner structures 22 are arranged in a row along the edge. The added parts 33 are put in place in a second time, being previously coated with successive portions of the polymerizable resin bead 30 on their underside. The attached parts 33 are thus glued simultaneously against the bottom wall 2 and against the main parts 32 of the corner structures 22.
- the cord sections 36 located under the successive angle structures 22 not necessarily enough to achieve a continuous edge.
- the interspace 35 may be 10 to 50 mm wide, including about 30 mm.
- connection sections 37 also made of polymerizable resin are used.

- the connecting section 37 of the polymerizable resin bead is initially deposited on the face of the bottom plate 39 intended to face the supporting structure.
- a flexible insulating lining strip for example made of glass wool, is inserted into the spaces between the corner structures 22 and the flat insulating blocks 21 and in the remaining part of the spacer space 35, so as to limit heat transfer by convection.
- a flexible insulating lining strip for example made of glass wool, is inserted into the spaces between the corner structures 22 and the flat insulating blocks 21 and in the remaining part of the spacer space 35, so as to limit heat transfer by convection.
- the combination of the insert 38 in a lower part of the spacer space 35 and a flexible band in the remaining part of the spacer space 35 makes it possible to obtain a guide of the flows of liquid without risk of overflow while leaving the possibility for the angle structures 22 to move or deform slightly at the intermediate space 35, especially in response to the deformations of the bottom wall 2 at sea.
