Damen unveils Marine Aggregate Dredger

Published in category: Dredging & Marine Contracting

Damen Shipyards Group has announced a new line of Trailing Suction Hopper Dredgers (TSHD), comprising of the Marine Aggregate Dredger (MAD) 4000 and 5600 vessels.

Designed in collaboration with Maritime Design and Engineering Services (MD&ES), the MAD 4000 and 5600 are welcome additions to Damen’s TSHD portfolio. The new vessels will be able to work in North Sea conditions up to depths of 60 metres. These capabilities allow sand and gravel mining farther from shore than preceding models.

Olivier Marcus, Damen’s Product Director Dredging comments: “We’ve tailored the technical specifications in line with the port infrastructure in the region in which the dredgers will operate. Furthermore, we’ve paid close attention to seakeeping behavior in order to ensure the vessels can operate comfortably and safely, even in harsh weather conditions.”

Future proof

The bow shape allows operation in adverse weather conditions. The shape is based on a proven Damen design. In addition to improved seakeeping behaviour, the bow shape also protects the sand and gravel cargo from green water ingress.

The MAD vessels have been developed with tomorrow in mind, states Mr. Marcus: “These vessels are future proof. Featuring Tier III engines and, requiring no ballast water, fully compliant with the latest IMO regulations, these dredgers are looking forwards. On top of that the design also takes into account the possible future requirement for advanced automation.”
