FIELD: transport.SUBSTANCE: proposed tank and floating structure are intended for transfer of liquefied natural gas. This tank has at least one wall including a sealed membrane to get in contact with tankage and support abutting of said membrane. Said support comprises at least one rectangular sheet with first row of parallel crimps extending over the sheet entire length. Second row of parallel crimps extends across said first row of crimps over the sheet width. Note here that said tank has reinforcing element arranged under one of first row crimp between membrane and support and having an outer shell. Its shape complies with that of crimp under which located is said reinforcing element. Said reinforcing element has inner channel extending through two opposite ends of said reinforcing element for gas to flow between crimp and support through reinforcing element.EFFECT: higher reliability.14 cl, 14 dwg |
