On February 15th, Shanghai Zhenhua Port Machinery (ZPMC) launched “Junlan,” China’s first fully electric deep-water assembled environmental dredger, built for China Communications construction company Tianjin Dredging, at the ZPMC Offshore.
“Junlan” was independently developed, designed, and constructed in China. The overall design reflects the concepts of “green, efficient, intelligent, and environmentally friendly,” and it has completely independent intellectual property rights. The vessel has a total length of 67 meters, a width of 11.95 meters, a maximum dredging depth of 25 meters, a total installed power of 4,520 kilowatts, and a cutter power of 600 kilowatts. Its standard dredging output is 2,200 cubic meters per hour, making it the most advanced environmentally friendly cutter suction dredger in China in terms of overall performance.
As a modularly designed dredging engineering vessel, all components of “Junlan” are weighted and dimensioned to meet the requirements for onshore transportation. They can be quickly assembled and disassembled, allowing transportation by truck or railway to inland rivers, lakes, or remote coastal areas. This breakthrough eliminates the reliance of traditional large dredgers on channel depth, aligning with the current trends and requirements of the green circular economy.
