The present invention discloses a securing device of a storage tank for liquefied natural gas (LNG). According to the present invention, a securing device of a storage tank for LNG comprises: a first sealing wall contacting LNG and keeping the LNG liquid-tight; a first insulation wall installed in an outer side of the first sealing wall; and a second insulation wall installed in an outer side of the first insulation wall. The securing device comprises: an insulation wall securing device securing the first and the second insulation wall; and an insulation plug installed to insulate a space generated by an installment of the insulation wall securing device in an upper portion of the insulation wall securing device. As such, the present invention provides a securing device that is capable of stably securing a gap between the first and the second insulation wall, keeping an LNG storage tank insulated in a part of a space where the securing device is installed, so as to secure safety of a ship, etc., increasing convenience of installment work and a production thereof, and reducing production costs as well.
