To provide a dome structure penetrating through a ceiling wall of a liquefied natural gas storage tank in which gas present in a secondary heat insulation barrier is circulated in a secondary space of the dome structure.SOLUTION: A liquefied gas storage facility includes a load bearing structure, a closed heat insulation tank and a dome structure. In the liquefied gas storage facility, the dome structure includes: an inner drum passing through an opening (27) formed in the load bearing structure; an outer drum (26) disposed around the inner drum and fixed to the load bearing structure around an annular part (34) of the load bearing structure; and a secondary discharge duct that appears in a secondary space. The annular part (34) of the load bearing structure includes a plurality of through holes (38) distributed around an annular passage part and allowing circulation of gas from a secondary heat insulation barrier to the secondary space.SELECTED DRAWING: Figure 4

    【課題】液化天然ガス貯蔵タンクの天井壁を貫通するドーム構造において、二次断熱バリア内に存在するガスを、ドーム構造の二次空間に循環させる。【解決手段】液化ガス貯蔵設備は、耐力構造と、密閉断熱タンクと、ドーム構造とを備え、前記ドーム構造は、前記耐力構造に形成される開口(27)を通過する内側ドラムと、前記内側ドラムの周りに配置され、前記耐力構造の環状部(34)の周りで前記耐力構造に固定される外側ドラム(26)と、前記二次空間内に現れる二次排出ダクトとを含み、前記耐力構造の前記環状部(34)は、前記環状通路部の周りに分布され、かつ、前記二次断熱バリアから前記二次空間までのガスの循環を許容する複数の貫通開口(38)を有する、液化ガス貯蔵設備。【選択図】図4
