Chinese shipbuilder Shanghai Zhenhua Heavy Industries (ZPMC) launched a new cutter suction dredger (CSD) into the water for the first time on Saturday, February 15.
Named Junlan, the non-self-propelled CSD will be operated by the Tianhang Bureau of China Communications Construction Company (CCCC). All the onboard machinery is powered by electricity, making it one of the first deep water-capable dredgers to be built in China.
The CSD has an LOA of 67 metres, a beam of 11.95 metres, and a total installed power of 4,520 kW. With the aid of a 600kW cutter, the dredger will be capable of extracting sediment at a rate of 2,200 cubic metres per hour, making it ideal for deployment in rivers, lakes, and dams.
The dredger is equipped with a high-efficiency, wear-resistant mud pump and an intelligent monitoring system. The underwater mud pump, the cabin mud pump, and the cutter are all powered by variable frequency drives.
The CSD is designed to permit operation by only one person if needed.
