Abstract
A part of a ship body is constructed as a liquefied gas tank by a simple method, and a liquefied gas tank manufacturing method and a ship are provided. The outer shell of the liquefied gas tank (10) is composed of an inner shell (14), an upper deck (16), and a bulkhead (18). The inner side surface of the tank outer shell and the periphery of a skeletal material (24) protruding inward from the tank outer shell are covered with a first thermal insulation layer (26), and the inner side surface of the first thermal insulation layer (26) is covered with a first polyurea layer (28) in a liquid-tight manner. Furthermore, the inner side surface of the first polyurea layer (28) is covered with a second thermal insulation layer (30), and the inner side surface of the second thermal insulation layer (30) is covered with a second polyurea layer (32) in a liquid-tight manner.
