ABSTRACT:
A liquefied gas storage tank having insulated vertical walls and an insulated top, said tank being located in and surrounded by a body of water with the exterior water level below the top of the tank walls, the tank interior space containing a layer of water in communication with the body of water so that water can be supplied to and be removed from the tank, an insulating layer floating on the water layer in the tank, and a liquefied gas floating on the insulating layer.
The insulating layer can include a float which extends over the water layer except for a rim space between the periphery of the float and the tank walls, and an insulating liquid in the rim space which has a specific gravity less than water and higher than the liquefied gas, and with the insulating liquid being essentially immiscible with water and remaining liquid at the liquefied gas storage temperature.
