The identical boosters have been designed and built by Damen Dredging Equipment. The containerised unit houses the Damen dredge pump, which is driven by a 1,095 kW Siemens electro motor, through a gear box. In a separate space the frequency drive and switch board are located. The booster stations receive their power via a local 690 V AC power cable. They can be operated from the dredge using remote control, including automatic control of the multiple dredge pumps. Each booster has the size of a 30’ container for practical relocation.

 

Both E-boosters have been tested extensively at the Damen Dredging yard in Nijkerk, the Netherlands.

 

The customer, Johann Bunte Bauunternehmung GmbH & Co. KG, is a well-known German family-owned contractor with a large portfolio in dredging and construction projects.

 

A Niedersachsen motorway project will be the maiden job for the silent boosters. They will work behind the stationary dredger Pirate II, and will pump 1.2 Mio. m³ sand over a distance of 7.6 kilometres through a nature reserve to the new A26 motorway near Hamburg.
