LIQUID STORAGE INSTALLATION

摘要

The invention relates to an underwater storage installation for a cryogenic liquid. The inventive installation comprises a foundation base (14) which rests directly on the sea floor (16), an underwater cell (18) for storing the cryogenic liquid and cryogenic liquid-supply (22) and -discharge (24) conduits. The aforementioned storage cell (18) comprises a sealed outer chamber (40) and a vapour barrier (60) which is disposed inside the outer chamber (40) and which defines a watertight space. Moreover, a separation space (70) is disposed between the outer chamber (40) and the vapour barrier (60). The storage cell (18) also comprises spacers (80) which are disposed in said space (70) and which keep the chamber (40) and the vapour barrier (60) at a distance from one another. The invention can be used for the storage of liquefied natural gas.
