Common structures of LNG storage tanks include vertical LNG storage tanks, horizontal LNG storage tanks, vertical sub parent tanks and atmospheric pressure storage tanks.
Vertical LNG storage tank:
The volume is 50 cubic meters, 100 cubic meters, 150 cubic meters and 200 cubic meters;
Horizontal LNG storage tank:
The volume is 60 cubic meters and 100 cubic meters;
Vertical sub master tank:
Sub master tank refers to an inner tank composed of multiple sub tanks in parallel to meet the demand of large capacity storage. Multiple sub tanks are assembled in a large outer tank in parallel. The number of sub tanks is 3-7, generally no more than 12. The volume of single sub tank should not be too large. Its volume is usually between 100 ~ 150 cubic meters, and the maximum is 250 cubic meters. There are 1000 cubic meters, 1750 cubic meters and 2000 cubic meters;
Atmospheric storage tank:
There are large and medium-sized atmospheric LNG storage tanks and extra large LNG atmospheric storage tanks.
