Damen has converted its first dredger to duel-fuel LNG/MGO propulsion. The 117 m, 8,500 m³ trailing suction hopper dredger Samuel de Champlain is owned by Rouen-based GIE Dragages-Ports and operated by the port of Nantes Saint-Nazaire.

Damen delivered a turnkey package that included engineering, procurement, installation, commissioning, and support. Key features included changing of the engines to dual-fuel (LNG/diesel) models, the installation of onboard LNG storage facilities, and maintenance support for the coming eight years.

The conversion work included a complete overhaul in original design and building an entirely new and larger engine room. Around 25 tonnes of piping was also re-engineered as well as a reduction in the amount of cabling needed for the interface.

Samuel de Champlain was built in 2002 and is based in the Grand Port Maritime of Nantes Saint-Nazaire and is used mainly in the Loire and Seine estuaries. The conversion project was made possible by a subsidy from the European Commission’s Innovation and Networks Executive Agency via its Connecting Europe Facility programme.

The results of the accompanying study will be presented at a conference, co-organised by CEDA. At the one-day conference, the retrofitted Samuel de Champlain will be doing trials. Delegates will have the opportunity to visit the retrofitted vessel in small groups and to get up close and personal with experts involved in the reconstruction and the operation of the dual-fuel dredger.
