Meet the first European dredge converted to dual fuel use

In 2019, MAN Energy Solutions France successfully re-engineered the dredge, Samuel de Champlain. Owned by GIE Dragages-Ports de Rouen, this dredge is operated by the port of Nantes Saint-Nazaire. As part of its conversion, we replaced its diesel-electric MGO combustion propulsion system with three MAN 6L35/44DF engines, which run on LNG, and installed an LNG storage system aboard. The Samuel de Champlain is the first European dredge to undergo a dual-fuel conversion.
