To provide a liquefied gas storage tank structure capable of releasing a pressure of gas in a gas pocket from a pressure release valve without being influenced by a pressure loss of a pressure release pipe by making uniform a gas pressure inside of a tank while including the pressure of the gas in the gas pocket inside of a liquefied gas storage tank generated in accordance with an attitude or oscillation of a ship or the like in which the liquefied gas storage tank is mounted, in a relatively simple configuration, a floating structure, and a release method for an internal pressure of the storage tank.SOLUTION: A liquefied gas storage tank structure comprises a gas dome 14 with which a pressure release valve 13 for discharging internal gas G to the outside is disposed in a tank body 12 of a storage tank 11. A pressure release port 15a is opened at a place of a gas pocket P in which a gas pool is generated in the storage tank 11. A pressure release pipe 15 connected to the pressure release port 15a is connected or introduced to the gas dome 14, and the gas G in the gas pocket P is guided into the gas dome 14.SELECTED DRAWING: Figure 1
【課題】比較的単純な構成で、液化ガス貯蔵タンクを搭載する船舶などの姿勢や動揺によって発生する、液化ガス貯蔵タンクの内部のガスポケットにおけるガスの圧力を含めてタンク内のガス圧力を均一化して、圧力逃がし管の圧力損失の影響を受けることなく、圧力逃がし弁からガスポケットにおけるガスの圧力を逃がすことができる、液化ガス貯蔵タンク構造、浮体構造物、貯蔵タンクの内部圧力の逃がし方法を提供する。【解決手段】貯蔵タンク11のタンク本体12に、内部のガスGを外部に放出する圧力逃がし弁13を配設したガスドーム14を備えると共に、貯蔵タンク11におけるガス溜りが生じるガスポケットPの場所に圧力逃がし口15aを開口し、この圧力逃がし口15aに接続する圧力逃がし管15をガスドーム14に接続又は導入して、ガスポケットPのガスGをガスドーム14の内部に導くように構成する。【選択図】図1
