Abstract

The concrete structure for liquefied natural gas (LNG) storage tanks is relatively simple but has a complicated construction procedure and takes a long time to construct. Also, because the inner tank cannot be constructed until the outer tank is finished, there are limitations to the current construction method in reducing the construction time. Therefore, a rapid method for LNG storage tank construction using precast concrete panels is proposed in this study to help shorten the construction time and improve quality control. The proposed method involves a change in the construction procedure. The precast concrete panels are used as the outer permanent form, and the wall liner is used as the inner permanent form for the outer tank wall. This is a new construction process that does not require installing and dismantling temporary forms. As a result, the inner and outer tanks can be simultaneously constructed once the self-standing wall liner is completed.
