D'Artagnan: a large cutter suction dredger from IHC Holland Merwede

摘要

What is probably the largest-ever self-propelled cutter suction dredger has recently been completed by the leading dredger specialist IHC Holland Merwede at its Kinderdijk yard. D'Artagnan, ordered by Soc de Dragage International SA (SDI), a French subsidiary of the Belgian company Dredging, Environment & Maritime Engineering NV (DEME), has been carefully engineered to provide a versatile operating platform (104.40m length bp and 25.20m breadth), capable of dealing effectively with a range of seabed soils, even with a swell running. The two spuds fitted at the stern enable straightforward spud guidance and direct propulsion, while the dredging ladder is at the bow, thus both dredging and sailing are in the same direction. This is a reversal of the arrangement on the 2004-built JFJ de Nul, also from IHC Holland but for the Jan de Nul group.
