Abstract:
According to the present invention, work barges 1A, 1B, 1C, are each provided with, as cranes, tower cranes 10, 10B, 10C in each of which a tower 12 is formed by stacking a plurality of mast blocks 12a, a crane body 13 is placed on the uppermost section of the tower 12, and the height of the tower 12 is adjusted by the number of stacked mast blocks 12a. Accordingly, in this work ship provided with a crane used for oceanic construction in shallow ocean regions, in particular, for the installation of a floor-type oceanic wind power generating device or the maintenance work thereof, the suspension height of the crane is easily changed corresponding to the height of the work target object, and during sailing when crane work is not performed, the height of the crane is lowered, the air draft is lowered, and the overturning moment acting on the base section of the crane is lowered, and thus, the scale of the base structure of the crane may be reduced to be small. Accordingly, an increase in the size of the hull is suppressed.
