Definitions

  • the invention relates to the field of sealed tanks.
  • the invention relates to the field of sealed and thermally insulating vessels intended for the storage and / or transport of liquid at low temperature, such as vessel tanks for the transport of liquefied petroleum gas (LPG) or for the transport of Liquefied Natural Gas (LNG).
  • LPG liquefied petroleum gas
  • LNG Liquefied Natural Gas
  • sealed and thermally insulating vessels are known designed to be fixed on a supporting structure and comprising a multilayer structure consisting of one or more sealing membranes and one or more insulation barriers. each of which is interposed between two sealing membranes or between a sealing membrane and the supporting structure.
  • the sealing membrane of each wall of the vessel comprises a plurality of metal plates having series of corrugations perpendicular to each other.
  • the corrugations thus allow the waterproofing membranes to deform under the effect of thermal and mechanical stresses generated by the fluid stored in the tank.
  • the tank When the tank is mounted in the double hull of a ship, it generally has a polyhedral shape defined by two octagonal end walls connected to each other by a wall of ceiling and a horizontal bottom wall, two walls vertical side walls, two upper oblique walls each connecting one of the side walls to the ceiling wall and two lower oblique walls each connecting one of the side walls to the bottom wall.
  • the two series of corrugations of the end wall sealing membrane are respectively oriented horizontally and vertically whereas the two series of corrugations of the membrane of the other walls are respectively oriented in the longitudinal direction of the vessel and perpendicular to the longitudinal direction of the vessel.
  • one of the corrugation series of each of the two adjacent walls extends in a direction perpendicular to the edge formed at the intersection between said two adjacent walls.
  • the corrugations of the two adjacent walls are arranged facing each other and the sealing membrane of the angle arrangement has corrugations which are arranged to ensure continuity of the corrugations of the sealing membranes at the the corner area between the two walls. Such continuity of the corrugations thus makes it possible to ensure satisfactory flexibility of the sealing membrane at the level of the angle arrangement and to limit the concentrations of stresses in this zone.
  • An idea underlying the invention is to provide a sealed tank of the aforementioned type in which the stress concentrations are limited in the corrugated sealing membranes, especially at at least one corner area between two walls. joining at a ridge that is secant to the direction of at least two sets of distinct undulations of the sealing membrane of one of the two walls.
  • such a tank may have one or more of the following characteristics.
  • each of the corrugations of the first and second series of ripples which intersect the edge is extended by one of the first or second corrugation deflection portions.
  • the first direction in which the corrugations of the first series of corrugations extend and the second direction in which the corrugations of the second series of corrugations extend are perpendicular to each other. .
  • the corrugations of the first series of corrugations and the corrugations of the second series of corrugations are spaced apart by the same inter-ripple distance x.
  • the corrugations of the third series of corrugations are spaced apart by a constant inter-ripple distance y.
  • the angle ⁇ between the edge and the first satisfied direction is 45 °.
  • the corrugations of the third series of corrugations are spaced along the edge of a first inter-corrugation distance y1 and a second inter-corrugation distance y2, the first and the second distance.
  • inter-ripple distances y1 and y2 being set so that the corrugations of the first series of corrugations and the corrugations of the second series of corrugations are spaced apart by the same inter-ripple distance x.
  • the third direction is perpendicular to the edge.
  • the tank has two end walls connected to one another by walls extending in the longitudinal direction of the tank and in which the first wall forms one of the two walls of the tank. end and the second wall forms one of the walls extending in the longitudinal direction of the vessel.
  • the second wall waterproofing membrane comprises a fourth series of corrugations comprising corrugations extending in directions parallel to the intersection between the first and second walls.
  • each wall of the tank comprises a thermally insulating barrier anchored to a supporting structure and on which is anchored the sealing membrane of the corresponding wall.
  • Such a tank may be part of an onshore storage facility, for example to store LNG or be installed in a floating structure, coastal or deepwater, including a tanker or LNG carrier, 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
