CONSTRUCTION METHOD OF HULL

PURPOSE:To improve the construction efficiency of a hull by constructing an upper shell and a bottom separately in a dock by floating the said upper shell in the dock filled with water and transferring it onto the said bottom for combining both of them. CONSTITUTION:In a dock, an upper shell 34 consisting of vertical bulkhead blocks 14, 15, outside shell blocks 16, 17, upper deck blocks 18-20, and others without a bottom is constructed separately from a bottom part 21 consisting of bottom shell blocks 11-13. Then, the dock is filled with water, and compressed air is injected into hollow chambers 35-37 of the upper shell 34. The said shell 34 is floated and transferred onto the bottom part 21, and combined together by joint parts 24, 25, 32, and 33. This construction permits to work under an open circumstance and improve the work efficiency.
