Recently, the sea trial operation of China's first deep-water plow dredging machine, which was independently implemented by CNOOC, an enterprise based in Tianjin Port Free Trade Zone, has been successfully performed in Yacheng Waters of South China Sea, filling the technical gap of plow dredger for deep-water submarine pipelines in China.
　　The plow dredger for this sea trial is the only plow dredger for deepwater submarine pipelines in China at present, and it is also one of the most powerful plow dredgers in the world at present. The projected area of the equipment exceeds 3 standard badminton courts, with a dead weight of 180 tons, a maximum operating water depth of 500 meters, and a maximum depth of 2.5 meters for dredging.
　　"Compared with the traditional jet dredging method, the soil shear force of the plough dredger equipment can be enhanced by five times and the dredging efficiency can be increased by three times, making it a genuine pioneering tool for offshore oil and gas development, which represents the advanced direction in the development of dredging equipment technology internationally." introduced by Lin Shouqiang, Chief Engineer of CNOOC Shenzhen Offshore Engineering Technology Service Co., Ltd.
