LIQUEFIED GAS STORAGE TANK WITH SAFETY VALVES

摘要

PURPOSE: A liquefied gas tank with a plurality of safety valves is provided to safely operate a tank if evaporative gas sharply increases and the inner pressure of the tank increases beyond allowable pressure. CONSTITUTION: A liquefied gas tank(10) is installed to store liquefied gas in hull of a marine structure(1) floating on the sea. The liquefied gas tank comprises a plurality of safety valves(11,12). The safety valve discharges evaporative gas from the liquefied gas tank and reduces the inner pressure of the liquefied gas tank. The safety valve has 100~200% of a capacity required for discharging evaporative gas in case of emergency. The safety valves are respectively installed on a separate gas discharge line.
