DC drives convert a three-phase supply into a adjustable DC voltage. Before the rise of frequency drive, these kinds of drives were applied everywhere in the dredging industry and especially in winch, cutter and pump applications.


Examples of projects which have been carried out by us:


Vlaaderen 19 (DEME): replacement of two AC electric motors (star- delta starting) by two DC motors of 995 kW.
Kaveri (DEME): replacement of old drives with new digital ones: cutter, 1030 kW underwater pump, two *ladder winches and two side winches of 147 kW.


Marco Polo (Jan de Nul): replacement of old drives with new digital ones: Two ladder winches, two side winches and a spud winch.
