National Bulk Carriers, Kure Shipyard, built two suction boom dredges "ZULIA" and "ICOA" in recent three years.The vessel has four (4) suction drags and a big rotating boom on the upper deck to discharge spoil far from ship side.The boom was constructed in welded truss with the pipe of the quenched-tempered high strength T1 and 2H steel to be possible saving of the structural steel weight.It will be much interesting to know the design and construction of the long cantieevered boom which could be fabricated satisfactorily by welding.
