Definitions

  • the invention relates to the field of tanks, sealed and thermally insulating, for the storage and / or transport of fluid, such as a cryogenic fluid. Sealed and thermally insulating tanks are used in particular for the storage of liquefied natural gas (LNG), which is stored, at atmospheric pressure, at approximately -162 ° C.
  • LNG liquefied natural gas
  • the invention relates more particularly to a gas dome structure which is intended to define a vapor circulation path between the interior space of the vessel and at least one vapor collector disposed outside the vessel.
