    Abstract: A liquefied gas such as propane is stored in underground galleries wherein there is a gaseous phase above a liquid phase and at the bottom, water in a sunk draining trap. The storage is worked, i.e., gas is introduced or extracted through tubes extending into the lower part of the liquefied gas.
