ンク。 Thermal insulation work on the surface of the upper half of the spherical tank mounted on the ship's hull via the skirt is supported by rails provided around the top of the spherical tank and the top of the skirt, respectively, and moved along the surface. This is done using a 1/4 arc-shaped movable scaffold that can be used for tank inspection, and a tank inspection site is installed on the back side of a hemispherical cover that is attached to the hull, covering the upper half of the spherical tank at appropriate intervals. In a spherical tank of a liquefied gas carrier that is pre-equipped with a ladder, the support structure for the tank inspection ladder is directly attached to a pair of left and right upper members attached to the back side of a hemispherical cover, and to the lower end of each of the upper members. Or a liquefied gas characterized by comprising a lower member that is removably connected via an intermediate member, has an inspection ladder attached to its lower end, and can be pulled up inside the upper member and temporarily fixed thereto. A spherical tank on a transport ship.
