ク。 The heat insulation work on the upper surface of a spherical tank mounted on a ship's hull via a skirt can be carried out along the surface while being supported by rails provided around the top of the spherical tank and the top of the skirt, respectively. This is carried out using a 1/4 arc-shaped movable scaffold that can be used for periodic tank inspections. In a spherical tank of a liquefied gas carrier which is equipped with a ladder in advance, the liquefied gas is characterized in that the tank periodic inspection ladder is attached to the back surface of the hemispherical cover via a support structure that is expandable and contractible in the radial direction. A spherical tank on a transport ship.
