<p>PROBLEM TO BE SOLVED: To provide a support structure of an on-water workbench ship in which even if a spud is inclined with respect to a guide device on a hull in the state that the hull is floated from a water surface by the spud, upper butt joint materials and lower butt joint materials of plural spacers interposed between a holding catch and a support material are equally brought into contact with each other.SOLUTION: A support structure of an on-water workbench ship is so configured that a support device 4 for supporting a hull in a floating state is hung by respective hanging materials 24 at plural positions in a circumferential direction from a support material 23 of a guide device 2, plural spacers 5, in which an upper butt joint material 51 and a lower butt joint material 52 vertically pressure-welded at plural positions in an outer peripheral direction of a spud 8 form a pair, are interposed between an upper surface of the support device 4 and a lower surface of the support material 23, and each contact surface of the upper butt joint material 51 and the lower butt joint material 52 in each spacer 5 forms a part of a spherical surface having a center at a height position P which is a half of a vertical length H of the guide device 2. Thus, even if the spud 8 is inclined with respect to the guide device 2, respective spacer 5 parts can be equally pressure-welded.</p> |
