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.
