Definitions
- the invention relates to the field of the construction of heat insulating elements for producing an insulating modular wall, in particular a tank wall for storing or transporting a cold liquid, in particular in a membrane tank for liquefied natural gas.
- heat insulating elements are used to transmit the hydrodynamic loading of the cargo from the waterproof membrane to the double hull, which implies a compressive strength function, and to isolate the cargo from the hull of the ship, to limit the heat flow causing the evaporation of the cargo, but also to protect the hull of cryogenic temperatures.
- FR-A-2877638 discloses a sealed and thermally insulated tank having a vessel wall attached to the hull of a floating structure.
- the tank wall has successively, in the thickness direction from the inside to the outside of said tank, a primary watertight barrier, a primary insulating barrier, a secondary watertight barrier and a secondary insulating barrier.
- the insulating barriers essentially consist of juxtaposed heat insulating elements.
- Each heat insulating element includes a bottom panel, a cover panel and a thermal insulation liner disposed in the form of a layer parallel to the vessel wall. Bearing elements rise through the thickness of said thermal insulation lining to take up the compressive forces.
- the elements carrying a heat insulating element include pillars of small cross section relative to the dimensions of the heat insulating element in a plane parallel to the tank wall.
- An idea underlying the invention is to provide a heat-insulating element relatively easy to manufacture, having good thermal performance and wherein the thermal insulation lining can be made of a material likely to contract more than its environment when cold, for example in a low density non-structural polyurethane foam.
- Certain aspects of the invention start from the idea of producing the thermal insulation lining with a single block of such material. Some aspects of the invention start from the idea of limiting the establishment of heat-induced stresses in the thermal insulation lining, when cold setting of the wall. Certain aspects of the invention start from the idea of providing a thermal insulation lining retained with the possibility of sliding relative to the supporting elements and a panel or several flat panels, to allow thermal contractions of different amplitude depending on the constituent materials of these elements.
- the invention provides a heat-insulating element suitable for producing an insulating barrier in a sealed and insulating tank, the heat-insulating element comprising a flat cover panel, a thermal insulation lining arranged parallel to the panel. cover and load-bearing members which extend through the thickness of said thermal insulation liner from the cover panel to take up compressive forces, the load-bearing members having a plurality of rigid pillars of small cross section relative to the dimensions of the cover panel engaged in recesses of the thermal insulation liner and attached to the cover panel, wherein, at normal temperature, a cross-sectional dimension of the pillar is for at least one of said pillars, or for each of said pillars , smaller than a corresponding dimension of the recess in which the pillar is engaged, from my to provide a gap between the pillar and the wall of the recess.
- such a heat-insulating element may comprise one or more of the following characteristics.
- the heat-insulating element further comprises a stuffing element of flexible material disposed in the gap between the pillar and the wall of the recess.
- the stuffing element is made of a material much less rigid than the thermal insulation lining so as to absorb itself most of the deformations induced by the different thermal contraction between the rigid structure and thermal insulation lining.
- the stuffing element is made of a material chosen from very low density polymer foams, manufactured glass wool, bulk glass wool, melamine foams, aerogels, polystyrene, polyester wadding in mattresses or in bulk.
- the pillars comprise a first pillar engaged in a first recess located in a central zone of the thermal insulation lining and a second pillar engaged in a second recess of the thermal insulation lining situated at a distance from the central zone of the thermal insulation liner, and wherein a cross-sectional dimension of the second recess is larger than a corresponding dimension of the first recess to allow differential thermal contraction between the thermal insulation liner and the cover panel, and wherein a stuffing member of flexible material is disposed in the second recess and no stuffing member of flexible material is disposed in the first recess.
- the pillars comprise a first pillar engaged in a first recess of the thermal insulation lining and a second pillar identical to the first pillar engaged in a second recess of the thermal insulation lining, the second recess being located at a greater distance from the center of the heat-insulating liner than the first recess, and wherein a cross-sectional dimension of the second recess is larger than a corresponding dimension of the first recess to allow for differential thermal contraction between the liner. thermal insulation and cover panel.
- all the recesses in which identical pillars are engaged have an increasing cross-sectional dimension, for example proportionally, with the distance between the recess and the center of the thermal insulation lining.
- one or each pillar is disposed in the recess so as to be closer to a wall of the recess facing towards the center of the thermal insulation lining than to a wall of the recess turned away from the center of the thermal insulation lining.
- the heat insulating element further comprises a flat bottom panel parallel to the flat cover panel, in which the thermal insulation lining is disposed between the bottom panel and the cover panel, the load-bearing elements extending through the thickness of said thermal insulation liner to the bottom panel, the cross section of the pillars being further small relative to the dimensions of the bottom panel and the pillars further being secured to the bottom panel.
- the pillars can be made with various shapes and orientations. According to one embodiment, the pillars extend perpendicularly to the cover panel and, where appropriate, to the bottom panel. Oblique pillars can also be used.
- one or each pillar may have a uniform section, which facilitates the realization and implementation of the pillar.
- one or each pillar may have a dimension in variable section along the thickness of said heat insulating liner, the sectional dimension being decreasing in the direction of the lid panel. Because the cover panel corresponds in use to the side facing the interior of the tank where the temperature is coldest, this arrangement leaves more room for the contraction of the thermal insulation liner where its amplitude tends to be the highest.
- the recesses can be made with various shapes and orientations.
- one or each recess has a uniform section, which facilitates the realization of the recess.
- one or each recess has a dimension in variable section along the thickness of said heat insulating liner, the sectional dimension being increasing in the direction of the cover panel. This arrangement also allows to leave more space for the contraction of the thermal insulation liner where its amplitude tends to be the highest.
- the thermal insulation lining comprises a block of polymer foam, in particular polyurethane.
- the thermal insulation liner has a relaxation slot extending in the thickness of the polymer foam block.
- the cover panel and the bottom panel may be made of various materials, for example plywood, composite material or other material capable of transmitting the forces while maintaining acceptable thermal properties.
- the thermal insulation liner is retained by the carrier elements with a possibility of sliding relative to the carrier elements and the cover panel.
- the invention also provides a sealed and insulating tank disposed in a supporting structure, the vessel having a vessel wall attached to the carrier structure, said vessel wall having successively, in the direction of thickness since the interior to the exterior of said vessel, a primary watertight barrier, a primary insulating barrier, a secondary watertight barrier and a secondary insulating barrier, at least one of the primary insulating barrier and the secondary insulating barrier having a juxtaposition of a plurality of the above-mentioned heat-insulating elements.
- Such a tank can be part of a land storage facility, for example to store LNG or be installed in a floating structure, coastal or deep water, including a LNG tank, a floating storage and regasification unit (FSRU) , a floating production and remote storage unit (FPSO) and others.
- FSRU floating storage and regasification unit
- FPSO floating production and remote storage unit
- a vessel for the transport of a cold liquid product comprises a double hull and a aforementioned tank disposed in the double hull.
- the invention also provides a method of loading or unloading such a ship, in which a product is conveyed. cold liquid through isolated pipelines from or to a floating or land storage facility to or from the vessel.
- the invention also provides a transfer system for a cold liquid product, the system comprising the abovementioned vessel, insulated pipes arranged to connect the vessel installed in the hull of the vessel to a floating storage facility. or terrestrial and a pump for driving a flow of cold liquid product through the insulated pipelines from or to the floating or land storage facility to or from the vessel vessel.

- the pillars are arranged in the form of a plurality of rows, in which each row of pillars 4 is supported on the bottom panel 3 by means of a batten 5 disposed between the bottom panel 3 and the end lower pillars of the row.
- the assembly of the pillars 4, slats 5 and panels 2 and 3 is made using fasteners, for example staples, nails or screws.
- the pillars 4 allow in particular the transmission of the stresses exerted on the cover panel 2 and therefore have a compressive strength function.
- a heat-insulating lining is disposed between the bottom panel 3 and the lid panel 2 and fills the space between the pillars 4.
- the pillars can be arranged in different ways.
- the successive rows of pillars are offset relative to each other. More specifically, the pillars 4 of a row are spaced according to a spacing regular and two successive rows are offset in the direction of their length by half a spacing. Such an arrangement allows a good compromise between the number of pillars 4 in the box 1 and the good distribution of the load.
- the rows of pillars are instead aligned. Other provisions of pillars 4 are still possible.
- the cover panel 2 of Figure 1 is a reinforced cover panel which has an upper panel 6 and a lower panel 7 which are spaced apart by a series of parallel solid beams 8.
- the beams 8 extend parallel to the longitudinal sides of the box 1.
- a beam 8 is each time positioned along and above a row of pillars 4.
- the beams 8 have a rectangular section.
- the beams 8 and the panels 6 and 7 are rigidly connected, for example by gluing or stapling.
- Such a reinforced lid panel structure provides good rigidity and effective load distribution in case of localized stress.
- Each beam 8 is spaced apart from the other beams 8 so as to define spaces 9 between the beams 8 and between the panels 6 and 7.
- These spaces 9 form channels parallel to the longitudinal sides of the box 1, which can for example be used for the circulation of a fluid between the two sides of the heat insulating box.
- the juxtaposition of heat insulating boxes thus makes it possible to form a circuit in a wall of the tank in which it is possible to inject a neutral gas to neutralize the wall of the tank and thus avoid any risk of explosion in case of leakage in the presence of 'oxygen.
- the rigid structure that has just been described can be made of wood or composite materials, for example polymer resin with or without reinforcing fibers.

This point will be explained by comparing Figures 2 and 3.
- FIG. 2 represents the box in a state of normal temperature, representative of the manufacturing conditions, namely for example an ambient temperature of between 10 ° C. and 30 ° C.
- FIG. 3 shows the box in a state of cryogenic use temperature, for example between 0 ° C. and about -100 ° C. if the box is used in the secondary barrier of an LNG tank and between about -100 ° C. and -160 ° C if the box is used in the primary barrier of an LNG tank.
- the contour 100 schematically represents the dimensions of the block of insulating material at the normal temperature while the contour 10 represents the block of insulating material at the cryogenic use temperature.
- the recesses 11 have retracted more than the pillars 4, so that the clearance spaces 12 are greatly reduced (they are no longer visible in Figure 3).

- This temperature variation is substantially invariant in the x, y plane.
- the temperature variation for a point in the pillar at the bottom of the heat insulating box where the temperature variation is the lowest is called AT chaU d.
- V p The overall manufacturing tolerance on pillar 4 is called V p , including the abutment positioning tolerance as well as the dimensional tolerance on the pillar section.
- the overall manufacturing tolerance on the block of insulating material 10 is called V, including the positioning tolerance of the recess 11 as well as the dimensional tolerance on the section of the recess 11.
- Dx mn and Dy mn are the dimensions of the recess 11 for a pillar
- C min is the center of the section of the recess 11 for a pillar P mn and XC mn , YC mn the coordinates of C min considered with respect to the center 13 of the box in the directions x and y respectively.
- These quantities also depend on the h-coordinate in the direction of the height in the case where the section of the recess is variable along this direction.
- Dx m n maXh ((Xmn, h + L m n, h / 2) AT h + Vp + Vi + L mn , h - [(X m n, + L m n, h / 2) * apx * AT c haud])
- Dy m n max h ((Y mn , h + i m n, h / 2) * a Y * AT h ) + Vp + Vi + i mn , h - [(Y m n, h + imn, h / 2) * apY * hot AT]

- This solution can be particularly suitable in the case of composite pillars.
- the block of insulating material 20 comprises several vertical relaxation slots 21, which makes it possible to segment the block 20 into several portions able to contract independently of one another, and thus to limit the size recesses 11.
