Damen Shipyards has unveiled its first Electric Cutter Suction Dredger (ECSD) 650, in which electric motors power the dredge system, enabling 'zero emission' dredging projects.

The electric power provides a significant reduction in noise, adding an extra tier of sustainability and ensuring the dredger’s suitability for projects in densely populated and environmentally sensitive areas.

The ECSD 650 is a modular dredger, based on Damen’s successful standardised shipbuilding philosophy, dismountable for transportation and easy assembly in the remotest of locations. Due to the standardisation of the design, Damen was able to quickly produce this sustainable product, without need for re-engineering. Standardisation further ensures the easy adaption of the ECSD principle to suit local power supplies.

On the conventional CSD 650, the rear side pontoons serve only to provide buoyancy; in the electric version the starboard side pontoon becomes an electrical nerve centre. The dredger’s low voltage system enables easy maintenance with no requirement for special crew training. Meanwhile, the associated reduction in vibrations during dredging improves cew comfort. 

Damen sales manager Sjoerd de Bruijn said: “The ECSD is just one example of the products and services that Damen is pioneering as we fix our focus on our goal: to be the most sustainable shipbuilder. Our role in this is not just to build electric vessels. As integrator we provide the connection, linking and aligning stakeholders from industry and academia. In this way we build a knowledge network that encourages the wider development of sustainable solutions and ensures the long-term viability of the maritime industry.”

The ECSD extends Damen's sustainable vessel range, which currently includes fully-electric and hybrid Ferries for Copenhagen and Canada and a fully-electric ship-handling tug for New Zealand.
