る。In general, for low 75.4 tanks made of aluminum alloy, etc., it is necessary to cover the top of the tank to protect it from fire when it is protruded from inside the hull to one side. A layer made mainly of foam glass is used as a heat insulating layer covering the foam glass, and glass wool is packed between the foam glasses as a cushioning material, and a special coating layer is applied to the outermost layer. .
そして、上述のタンク上部の被覆層から離隔した位置で
同タンク上部を覆うように、鋼製カバーが船上に設けら
れており、これにより火災源からの輻射熱を防ぐように
なっている。A steel cover is installed on the ship to cover the upper part of the tank at a location away from the above-mentioned coating layer on the upper part of the tank, thereby preventing radiant heat from the fire source.

点が、（））る。However, in the tank upper coating structure of conventional low-temperature tank ships, the foam glass that constitutes the coating layer is brittle and vulnerable to impact and friction, so it is necessary to apply a special coating layer to its surface. Moreover, forming the curved surface of the foam glass layer requires a large number of man-hours and causes a considerable amount of material loss.
寸だ鋼製カバーがタンク上部の外面から離隔した位置に
設けられるので、その支持構造が別途に必要になるとい
う問題点もある。Another problem is that a separate support structure is required because the steel cover is provided at a distance from the outer surface of the upper part of the tank.
