Document Type and Number:
WIPO Patent Application WO/2019/039132
Kind Code:
A1
Abstract:
A storage tank 11 wherein a tank main body 12 is equipped with a gas dome 14 wherein is arranged a pressure release valve 13 for discharging an interior gas G to the outside, a pressure release opening 15a is disposed at the location of a gas pocket P where a gas buildup occurs in the storage tank 11, a pressure release pipe 15 connected to this pressure release opening 15a is connected to or introduced into the gas dome 14, and the gas G in the gas pocket P is guided into the interior of the gas dome 14. Thus, it is possible to provide a liquefied gas storage tank structure, a floating structure, and a method for releasing internal pressure of a storage tank wherewith by means of a comparatively simple configuration, the gas pressure in a tank can be made uniform and the pressure of the gas in the gas pocket released via a pressure release valve without being affected by loss of pressure in the pressure release pipe, said gas pressure in a tank including the pressure of gas in a gas pocket inside a liquefied gas storage tank, the gas pocket arising from the attitude or turbulent motion of a ship or the like wherein the liquefied gas storage tanks is installed.
