PURPOSE:To prevent yielding of complicate thermal stress as well as effectively utilizing the space by partly unifying the tank of melted material at high temperature with hull construction. CONSTITUTION:The hull 1 has double bottom structure 2, and the plural number of tanks 3 to accomodate melted material at a high temperature such as asphalt are parallely arranged in the hull. The tank wall 4 of each tank 3 is arranged almost parallel to it inside the ship's outer board 5, and front and after walls of the tank 10 are arranged in parallel with the ships bulkhead 6, being separated from it. Each tank 3 is partially integrated with the hull at the bottom only. As for the heat prevention means, non pressure resisting and non liquid tight heat prevention layer 8 is stretched on the upper side of the tank's bottom plate 7, and heat prevention layer 11 is stretched over the outer surface of the other tanks. |
