Claims

[Scope of utility model registration request]

A water intake column that is guided so as to be relatively vertically movable by a vertical guide member provided on the side of the lifting leg of the offshore working platform and penetrates the upper and lower sides of the offshore working platform, and a side surface of the water intake column on the opposite side of the lifting leg. The water intake column has a vertical rack and a plurality of guide rails fixed to the section, a drive pinion meshing with the rack and a guide shoe guiding the guide rail, and is arranged in parallel to the water intake column so as to be relatively movable up and down. A water intake lifting column device for an offshore working platform, comprising: a water intake column lifting mechanism slidably mounted on a sliding plate on the offshore working platform.
