The dredge is electrically powered and drives a high-flow, low pressure seawater pump through a venturi system. It runs with an effect of 235 kW and has been equipped with ejector based-dredge system from 8-16”. The system can also be equipped with water jetting on the suction head if disintegration og hard materials is required.
