This dredger is the first engineering vessel accredited by China Classification Society for unlimited navigation area. The vessel is driven by propellers and equipped with two 360 ° rotary cranes, mainly engaged with wreck salvage and dredging, with a prominent advantage over its competitors in the industry of deep-water salvage and dredging. The 60 m3 dredging crane is currently the most self-developed fully hydraulic system controlled by the largest bucket of grab dredging cranes, the deepest can excavate 200 meters water depth, the obvious advantage with the Japanese SKK dredging crane. At present, the weight of the grab and the world of the bucket are ranked second. The weight and function of the free-falling weight hammer are the first in the world. It can effectively cope with the world’s largest displacement wreck and the hardness of rock above 50 MPa.
