The 3,500 m3 Trailing Suction Hopper Dredger Diogo Cao was launched last Saturday 14-07-2018 at the Keppel Nantong shipyard in China, a subsidiary of Keppel Offshore & Marine. This green vessel is the second of three 3,500 m3 hoppers to be launched, equipped with an exhaust gas treatment system filtering out and virtually eliminating many pollutants from the exhaust gases. In total, Jan De Nul Group ordered six such ultra-low emission Trailing Suction Hopper Dredgers, called Ultra-Low Emission Vessels, five of which are being built at Keppel: three small 3,500 m3, two medium-sized 6,000 m3 and a larger vessel at 18,000 m3.
