Samuel de Champlain
Damen Shiprepair & & Conversion has actually finished the conversion of the 117 m dredge S amuel de Champlain to dual-fuel procedure on dissolved gas (LNG) and also aquatic gas oil (MGO).
The initially conversion of its kind to be finished in Europe, the job becomes part of an EU-supported effort to advertise LNG propulsion in short-sea vessels running along the European Atlantic shore.
The 8,500 cubic meter routing suction receptacle dredge is possessed by Rouen, France, based GIE Dragages-Ports and also run by Port of Nantes-Saint-Nazaire
Its conversion was accomplished in Damen Shiprepair’s Dunkirk, France, shipyard and also entailed the substitute of the vessel’s diesel-electric MGO-burning propulsion system with 3 guy 6L35/44DF dual-fuel engines, in addition to the setup of onboard LNG storage space centers.
Louis-Marie Rouxel, Project Manager for Damen, stated: “The main reason for choosing MAN was the performance of its highly competitive 35/44 DF engine in response to load impacts. The unique demands of dredges required engines capable of supporting great loads and, as a result of our studies, it turned out that this was the engine that best met these parameters.”
Lex Nijsen, Head of Four-Stroke Marine Sales, GUY Energy Solutions, stated: “This is a significant moment for European shipping, as evident by the support the EU is offering. This conversion is just the beginning of a path that will lead to a comprehensive LNG infrastructure around the continent in the pursuit of more efficient propulsion and cleaner emissions. I’m very happy that the MAN 35/44DF engine has been deemed worthy of meeting the demanding criteria that both the dredger world and this broader project require.”
The Samuel de Champlain was constructed in 2002 and also is the biggest dredge in the GIE Dragages-Ports fleet. Based in the Port of Nantes-Saint-Nazaire, the vessel runs in between the Loire and also Seine tidewaters.
Among the benefits that led Damen and also Dragages-Ports to choose a guy 35/44DF propulsion service were:
- superior load-step ability that can deal with the high load-fluctuations that are normal for dredge applications
- capacity to dig up continually in gas-mode procedure (Tier III) without changing over to diesel-mode (Tier II)
- pure gas-start ability for marginal NOx discharges from beginning of procedure
- gas-mode procedure from 0– 110% tons, without requirement to switch to diesel procedure upon getting to 100% tons– simply put, continual Tier III procedure with marginal NOx discharges
- automated flexible burning control in case of transforming ambient problems, gas top quality, damage, and so on with the capacity to preserve gas procedure at the greatest performance gradually
- the capacity to run despite having bad gas-quality, to a methane variety of 70 MN, without derating the engine power outcome, allowing procedure on a bigger selection of gas with various high qualities and also cost.
