Definitions

  • the invention relates to the field of waterproof and thermally insulating membrane tanks for the storage and/or transport of fluid, such as a liquefied gas.
  • Tight and thermally insulating membrane tanks are used in particular for the storage of liquefied natural gas (LNG), which is stored at atmospheric pressure at approximately -163°C. These tanks can be installed on land or on a floating structure. In the case of a floating structure, the tank may be intended for the transport of liquefied natural gas or to receive liquefied natural gas serving as fuel for the propulsion of the floating structure.
  • LNG liquefied natural gas
  • the document WO-A-89/09909 discloses a sealed and thermally insulating tank for storing liquefied natural gas arranged in a supporting structure and whose walls have a multi-layer structure, namely from the outside towards the inside of the tank, a secondary thermally insulating barrier anchored against the structure carrier, a secondary waterproof membrane which is supported by the secondary thermally insulating barrier, a primary thermally insulating barrier which is supported by the secondary waterproof membrane and a primary waterproof membrane which is supported by the primary thermally insulating barrier and which is intended to be in contact with liquefied natural gas stored in the tank.
  • the primary insulating barrier comprises a set of rigid plates which are held by means of the weld supports of the secondary waterproof membrane.
  • the primary waterproof membrane is formed by an assembly of rectangular sheets having undulations in two perpendicular directions, said sheets being welded together overlapping and being welded by their edges on metal strips fixed in rebates along of the edges of the plates of the primary insulating barrier.
  • EP0064886A1 describes a watertight and insulating tank, integrated into the supporting structure of a ship, comprising two successive alternating sealing barriers with two thermally insulating barriers.
  • the secondary sealing barrier is made up of an assembly of welded invar strakes with raised edges.
  • the primary sealing barrier is made up of an assembly of sheets, the edges of which are overlap welded and attached to the primary insulating barrier by welding onto metal inserts of the primary insulating barrier.
  • the sheets are embossed and have corrugations in two perpendicular directions.
  • WO2008007837A1 describes an LNG tank whose wall includes a secondary membrane formed of invar strakes welded to tongues carried by secondary insulation panels.
  • a primary insulation panel is located on each invar strake placed between the tongues and a connection unit connects the edge of the primary insulation panel to each adjacent tongue.
  • An idea underlying the invention consists of providing a tank wall combining the advantages of a secondary membrane formed of parallel strakes, the robustness of which has been proven by experience, and of a corrugated primary membrane, which can present very good resistance to accidental indentations and other stresses, resulting for example from thermal contraction, cargo movements and/or deformation of the ship's beam at sea.
  • Another idea underlying the invention consists of providing a tank wall which is relatively easy to manufacture and which allows different types of corrugated waterproof membranes to be used as a primary membrane.
  • the invention proposes a waterproof and thermally insulating tank according to claim 1.
  • the primary rows are offset in the second direction by a fraction, for example half, of the dimension of the repeated pattern of the secondary rows relative to the secondary rows. Thanks to such an offset, it is possible to limit or eliminate the vertical alignments between primary retaining members and secondary retaining members, which limits the occurrence of thermal bridges caused by these alignments.
  • Another advantage of shifting the primary rows in the first and/or second direction is to obtain a more uniform distribution of the forces passing through the membranes and the primary insulation and being reflected on the secondary insulating panels and the supporting wall. Indeed, in this case, a pressure force exerted on a primary insulating panel is distributed over several, for example two or four, underlying secondary insulating panels.
  • the interfaces between the primary insulating panels within a primary row are offset in the first direction relative to the interfaces between the secondary insulating panels within the two secondary rows on which the primary row is superimposed.
  • the primary retaining members are carried by the secondary insulating panels at a distance from the edges of the secondary insulating panels, for example at the centers of the secondary insulating panels.
  • Such primary retaining members can be provided on all the secondary insulating panels, for example if the primary insulating panel has the same dimensions as the secondary insulating panel, or on some of the secondary insulating panels, for example if the primary insulating panel is more long as the secondary insulating panel or if the primary insulating panel is offset only in the first direction.
  • a primary retaining member comprises a plate fixed to a cover plate of the secondary insulating panel under the secondary waterproof membrane and a rod attached to said plate, fixedly or with a horizontal clearance, and passing through the membrane in a sealed manner secondary waterproofing towards the primary insulating barrier.
  • the primary waterproof membrane has first undulations parallel to the first direction and arranged in a repeated pattern in the second direction and flat portions located between the first undulations and resting on an upper surface of the primary insulating panels, and the dimension of the repeated pattern of the primary rows is an integer multiple of the dimension of the repeated pattern of the first undulations
  • the primary waterproof membrane comprising a plurality of rows of sheets parallel to the first direction, a row of sheets comprising a plurality of rectangular sheets welded together in a sealed manner by edge zones, without or with mutual overlap, the rows of sheets being juxtaposed in the second direction and welded together in a sealed manner, the dimension of a row of sheets in the second direction being equal to an integer multiple of the dimension of the repeated pattern of the primary rows.
  • the repeated pattern of the first ripples may be a repeated pattern comprising one ripple or several ripples.
  • a repeating pattern having a single undulation means that the first undulations are spaced a first regular spacing in the second direction and that the dimension of the repeating pattern is equal to this first even spacing.
  • the dimension of the repeated pattern of the primary rows is an integer multiple of said first regular spacing.
  • a repeating pattern with multiple ripples means that the spacing of the ripples is not necessarily regular, but all spacings repeat at a regular interval, called the dimension of the ripple repeat pattern.
  • the rows of sheets are offset in the second direction relative to the primary rows so that the welded junctions between the rows of sheets are located at a distance from the interfaces between the primary rows, that is to say in particular at a distance retaining devices.
  • the welded junctions between the rows of sheets of the primary waterproof membrane can essentially be made at a distance from the edges of the primary insulating panels parallel to the first direction, therefore on a surface having a high level of flatness. This results in a lower risk of local variation of the welds and a higher level of quality of the membrane obtained.
  • such a tank may have one or more of the following characteristics.
  • a primary row comprises a plurality of parallelepiped primary insulating panels juxtaposed in a repeated pattern and a row of sheets of the primary waterproof membrane comprises a plurality of rectangular sheets juxtaposed in a repeated pattern, the dimension of the repeated pattern rectangular sheets being equal to an integer multiple of the dimension of the repeated pattern of the primary insulating panels in the first direction.
  • the edges of the rectangular sheets are offset in the first direction relative to the edges of the primary insulating panels parallel to the second direction, so that the welded junctions between the rectangular sheets are located at a distance from the edges of the insulating panels primaries parallel to the second direction.
  • the primary insulating panels and/or the secondary insulating panels have a square shape.
  • the primary row repeat pattern and/or the secondary row repeat pattern may or may not have a gap in the second direction. If there is a gap between two rows, the dimension of the repeated pattern is equal to the sum of the dimension of the primary or secondary insulating board and the dimension of the gap.
  • the repeated pattern of primary or secondary insulating panels within a primary or secondary row may or may not have a gap in the first direction. If there is a gap between two primary or secondary insulating panels, the dimension of the repeating pattern is equal to the sum of the dimension of the primary or secondary insulating panel and the dimension of the gap.
  • the dimension of a strake in the second direction is an integer multiple of said first regular spacing.
  • the primary waterproof membrane also has second undulations parallel to the second direction and arranged in a repeated pattern in the first direction, the flat portions being located between the first undulations and between the second undulations.
  • the repeating pattern of the second ripples may be a repeating pattern comprising one ripple or multiple ripples.
  • a repeating pattern with a single ripple means that the second ripples are spaced one second regular spacing in the first direction. In this case, the second regular spacing may be equal to or different from the first regular spacing.
  • a repeating pattern with multiple ripples means that the spacing of the ripples is not necessarily regular, but all spacings repeat at a regular interval, called the dimension of the ripple repeat pattern.
  • the first and second undulations can be continuous or discontinuous at the intersections between first and second undulations. Thanks to continuous undulations, it is possible to produce continuous channels, for example for the circulation of a neutral gas, between the primary waterproof membrane and the primary insulating barrier. Thanks to discontinuous corrugations, it is easier to form the sheet by stamping.
  • the dimension of the repeated pattern of the primary insulating panels is an integer multiple of the dimension of the repeated pattern of the second corrugations, for example an integer multiple of said second regular spacing.
  • a rectangular sheet of the primary waterproof membrane has a dimension in the first direction substantially equal to an integer multiple of the dimension of the repeated pattern of the second undulations or an integer multiple of the second regular spacing. A slight difference may exist between these two quantities, less than the dimension of the overlap between two adjacent sheets.
  • the primary waterproof membrane is retained on the primary insulating barrier by anchoring means which can be produced in different ways.
  • the anchoring means comprise metal anchoring strips fixed on the primary insulating panels at locations corresponding to the contours of the rectangular sheets and on which edge zones of the rectangular sheets can be welded.
  • a primary insulating panel may in particular comprise an anchoring strip for fixing a rectilinear edge of one or more rectangular sheets or two intersecting anchoring strips for fixing a corner zone of one or more rectangular sheets.
  • the anchoring means comprise metal inserts, for example in the form of discs, fixed on the primary insulating panels at locations corresponding to edge zones of the primary insulating panels distant from the contours of the rectangular sheets and on which central areas of rectangular sheets can be welded.
  • a primary insulating panel comprises relaxation slots cut in a direction of thickness of the primary insulating panel and opening onto a cover plate of the primary insulating panel.
  • one or each metal anchor strip may comprise several aligned segments, fixed on the cover plate and separated by the relaxation slots and/or the metal inserts can be fixed on the cover plate between the slots relaxation.
  • At least one of the insulating panels comprises a bottom plate resting against the supporting structure or the secondary waterproof membrane, an intermediate plate placed between the bottom plate and the cover plate, a first layer of insulating polymer foam sandwiched between the bottom plate and the intermediate plate and a second layer of insulating polymer foam sandwiched between the intermediate plate and the cover plate.
  • recesses are provided in the second layer of insulating polymer foam so that the intermediate plate projects beyond the second layer of insulating polymer foam and thus provides one of the support zones for the secondary restraints.
  • the first layer of insulating polymer foam has, in each of the corner zones of the insulating panel, a cutout housing a pillar which extends between the bottom plate and the intermediate plate. This helps limit crushing and creep of the foam.
  • At least one of the insulating panels comprises a bottom plate, a cover plate and supporting sails extending, in the thickness direction of the tank wall, between the bottom plate and the cover plate and delimiting a plurality of compartments filled with an insulating lining, such as perlite.
  • a bridging element can be attached to the upper surfaces of several adjacent primary insulating panels, for example two or four adjacent primary insulating panels, for example to the cover plates of the adjacent primary insulating panels, to avoid spacing adjacent primary insulating panels, in other words to avoid the creation of a gap between the adjacent primary insulating panels or at least the widening thereof.
  • the primary insulating panels have countersinks on the edges of the upper surface to receive the bridging element(s), for example plywood bridging plates.
  • Such a tank can be part of a land storage installation, for example to store LNG or be installed in a floating, coastal or deep water structure, in particular an LNG ship, a floating storage and regasification unit (FSRU) , a floating production and remote storage unit (FPSO) and others.
