The Samuel de Champlain, a 117 m, 8500 ton dredger, belongs to GIE Dragages-Ports, headquartered in Rouen, and is fitted out and operated by the Grand Port Maritime de Nantes Saint-Nazaire (Nantes Saint-Nazaire Port).

Three years ago, the vessel was converted to LNG, which involved replacing its diesel generators with three MAN 6L35/44DF engines that can run on diesel fuel and gas. Simultaneously, an LNG storage system was also installed on board. The conversion of the Samuel de Champlain to liquefied natural gas was the first of its kind in Europe.

“Based on the experience we had with MAN Energy Solutions when converting the dredger, we wanted to renew our trust in the MAN Energy Solutions team that has a great deal of expertise,” said Hubert Louys, maintenance manager for Dragages-Ports.

“We are happy to continue our partnership on this project beyond the installation of the new engine, carried out in 2019,” said Jordan Morvan, Project Manager, MAN Energy Solutions France. “Work to optimize maintenance plans has since been carried out in close collaboration with GIE to ensure the dredger’s increased availability,”

The MAN 35/44DF propulsion system was selected was due to certain, crucial characteristics, including:

- the ability to handle the large load fluctuations typical in dredging applications.

- the option of dredging continuously in gas mode (Tier 3) without swapping to diesel mode (Tier 2).

- the ability to start in gas mode for minimal NOx emissions from the start of operations.

The Samuel de Champlain was built in 2002 and is the biggest vessel in the GIE Dragages-Ports fleet. Based at the Nantes Saint-Nazaire port, the vessel operates in the Loire and Seine estuaries.
