Damen extends TSHD range

The shipbuilder noted that the updated portfolio includes hopper dredgers for port maintenance and multi-purpose dredgers with capacities between 2,200m³ and 5,000m³.

The designs for the dredger are intended to be both practical in operation and in maintenance, and have a sustainable future-proof design.

“Practical maintenance is of vital importance on a TSHD. Due to the continuous wear of the sand/water mixture all piping and main components need frequent checks,” Olivier Marcus, Damen product director Dredging, explains. “In the design this has resulted in an efficient pipe routing, the use of high grade materials and ample space around the equipment for inspection and repairs.”

Moreover, the shipbuilder notes that the new series has been designed with sustainability in mind. For instance, no ballast water is needed throughout the operations, including sea voyages.

And the designs do not have any fuel tanks in contact with the hull to avoid any future problems. The fully optimised engines are fitted out with an SCR system, prepared for IMO Tier III, as can be expected from a responsible shipyard.

“Dredge operators always have a clear idea on the various tasks their hopper dredger is to perform, whether, for instance, channel maintenance for a Port Authority or efficient sand winning, transport and discharge for a commercial operator.” Olivier explains, “This specific operation requires specific gear; the new TSHD range accommodates this. As hopper volumes range from as small as 650 m³ to 5,000 m³, they fit a multitude of jobs.”

Moreover, each TSHD-type can be customised easily. “This standard range can be seen as a platform which can be fully customised by adding various options to ensure the dredger is 100% fit for its job,” Olivier concluded.
