LIQUEFIED GAS STORAGE TANK AND SHIP INCLUDING THE SAME

摘要

PURPOSE: A liquefied gas storage tank and a ship with the same are provided to prevent the leakage of liquefied gas by reinforcing the lower part of the liquefied gas storage tank. CONSTITUTION: A liquefied gas storage tank(100) comprises a barrier(110), a reinforcing barrier(120), and a leaked liquid storage space(130). The barrier is separated supported on the inner side(2) of a hull(1) and stores liquefied gas inside thereof. The reinforcing barrier is installed at the bottom of the barrier to reinforce the barrier. The leaked liquid storage space is formed between the barrier and the reinforcing barrier and comprises a leaked liquid inlet for storing liquefied gas leaked liquid leaked from the barrier. Some of the liquefied gas leaked liquid flows in the leaked liquid storage space through gaps(3) formed between the inner side of the hull and the barrier.
