  • An embodiment relates generally to a support structure for a liquid cargo storage tank.
  • liquefied gas carriers are used to carry these liquefied gases in bulk from a production base to varying locations in order to use them as energy.
  • the liquefied gas carriers carry the liquefied gases at very low temperatures below zero, whereby the volume of liquefied gases is reduced to thereby increase the amount of liquefied gases being carried.

  • the width of the slope blocks 124 may decrease toward a side where a pair of the slope blocks 124 are close to each other. As the slope blocks 124 are closer to each other, the distance between the first plate 121 and the second plate 122 may increase.
  • first through holes 124A may be formed in the slope blocks 124 so that the tensile members 123 may pass through the first through holes 124A.

  • the slope blocks 124 may protrude outside the first plate 121 and the second plate 122 so that the first plate 121 and the second plate 122 may meet as illustrated in FIG. 7 .

For example, since the fixing members 126 are inserted into the fix blocks 125, the fixing members 126 may press and fix the tensile members 123.
  • the entire height of the support structure for a liquid cargo storage tank may be primarily controlled by the filler member 112, and subsequently, the height may be reset by the distance control unit 120.
