PRIMESERV MAINTENANCE CONTRACT FOR PIONEERING DUAL-FUEL DREDGER

Jul 28, 2022 | Marine propulsion & machinery news

MAN PrimeServ, the after-sales service brand of MAN Energy Solutions, has signed a long-term service agreement (LTSA) with GIE Dragages-Ports, which includes inspection kits and preventative maintenance services as well as remote assistance (PrimeServ Assist) and engine-fluid analysis (PrimeServ LAB).

The Samuel de Champlain dredger (117 m, 8,500 m³) 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 installed on board. The conversion of the Samuel de Champlain to LNG was the first of its kind in Europe.

Hubert Louys, Maintenance Manager Dragages-Ports, said: “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.”

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

The MAN 35/44DF propulsion solution is claimed to offer:

  • outstanding load capacity – capable of handling the large load fluctuations typical in dredging applications;
  • option of dredging continuously in gas mode (Tier III) without swapping to diesel mode (Tier II);
  • ability to start in gas mode for minimal NOx emissions from the start of operations.

GIE Dragages-Ports owns a fleet of seven dredgers, operating in eight ports along France’s Atlantic, English Channel and North Sea coastlines. The Samuel de Champlain was built in 2002 and is the largest vessel in the GIE Dragages-Ports fleet. Based at the Nantes Saint-Nazaire port, the vessel operates in the Loire and Seine estuaries.
