RECONSTRUCTION METHOD OF BOAT INTO FLOATING DOCK

PURPOSE:To reconstruct a built-up tanker into a dock in use of its construction by cutting away the middle part of each of side girders of a tanker, moving a longitudinal bulk-head toward the broadside to be joined there as dock side walls and shifting both and upper deck and the lower transverse girder of the deck downward to be used as the internal bottom board of a dock double bottom. CONSTITUTION:The middle part, namely, the shaded part of each of tanker side girders 25 is cut away, shearing an upper deck 4 at positions 20 and a longitudinal bulkhead 8 at positions 22 and 24, and the longitudinally bulkhead 8 and the side girder 23 are slided toward the broadside and joined to the broadside, whereby forming dock side walls. The upper deck 4 and the lower side girder 21 of the deck are carried downward and then used as the internal bottom board 13 of a dock double bottom construction 29. At that time, the internal board is longitudinally displaced by a half of the distance between the conters of frames so that the bottom side girder 30 and the deck lower side girder 21 are prevented from overlap each other. By making a good use of the hull construction of a built-up tanker, a dock may be constructed easily.
