Manufacturing method of floating structure

Abstract

To provide a manufacturing method of a floating structure capable of suppressing biting of foreign matters between a block and a frame.SOLUTION: The manufacturing method of a floating structure comprises the steps of positioning a block (for example, a first block 21), a part of a floating structure, vertically above a bottom part 62 of a floating dock 61 in the floating state on the water surface, and moving the floating dock 61 relatively upward with respect to the block to mount the block on multiple frames 64 provided on the top face of the bottom part 62 of the floating dock 61. In the step of mounting the block on the multiple frames 64, a water flow W1 toward the space between the block and one frame 64 is formed by a water flow formation mechanism 640 before the block and the one frame 64 come into contact. This can prevent the foreign matters from biting between the block and the frame 64.SELECTED DRAWING: Figure 13
