Abstract: Disclosed is a pump tower disposed inside a liquefied gas storage tank so as to supply or discharge liquefied gas to/from the inside of the liquefied gas storage tank. The pump tower, according to one embodiment of the present invention, comprises: a discharge pipe used for discharging the liquefied gas in the liquefied gas storage tank; an emergency pipe equipped with an emergency pump at the lower end thereof; a charge pipe for supplying the liquefied gas into the liquefied gas storage tank; and a support, which is provided on the bottom of the liquefied gas storage tank, for enabling the vertical displacement of the pump tower and restricting the horizontal movement and rotation thereof. The support comprises: a lower body fixed to a hull side; an upper body fixed to a pump tower side; and a wedge member interposed between the lower body and the upper body.
