Liquefied natural gas storage tank

   
   

Substantially rectangular-shaped tanks are provided for storing liquefied gas, which tanks are especially adapted for use on land or in combination with bottom-supported offshore structure such as gravity-based structures (GBS). A tank according to this invention is capable of storing fluids at substantially atmospheric pressure and has a plate cover adapted to contain fluids and to transfer local loads caused by contact of said plate cover with said contained fluids to a grillage of stiffeners and stringers, which in turn is adapted to transfer the local loads to an internal truss frame structure. Methods of constructing these tanks are also provided.

Os tanques substancialmente rectangular-shaped são fornecidos armazenando o gás liquefied, que os tanques são adaptados especial para o uso na terra ou em combinação com a estrutura offshore fundo-suportada tal como as estruturas gravidade-baseadas (GBS). Um tanque de acordo com esta invenção é capaz de armazenar líquidos na pressão substancialmente atmosférica e tem uma tampa da placa adaptada para conter líquidos e para transferir as cargas locais causadas pelo contato de tampa dita da placa com líquidos contidos ditos a um grillage dos reforçadores e das longarinas, que seja adaptado por sua vez para transferir as cargas locais a uma estrutura interna do frame do truss. Os métodos de construir estes tanques são fornecidos também.
