Abstract
An offshore structure is provided for handling cryogenic fluids such as liquefied natural gas. The structure comprises a lower section of concrete and an upper section which projects up from the lower section above the sea level to support a deck superstructure. The lower section is formed of a plurality of cells and at least one of the cells houses an insulated tank for the storage of low temperature fluids. The tank or tanks are completely submerged when in operation and are rigidly supported by the associated cell. Each tank comprises a primary and secondary barrier with insulation associated therewith and the tank(s) communicates with the deck superstructure through an access tunnel system.
