The installation includes a redundant energy system up to 6 x 4,100 kVA with low and high voltage switchboard and a propulsion system consisting of 3x2,950 kW azimuth propellers, situated in the aft ship and two rudder propellers situated in the fore ship of 2,400 kW each, as well as a 2,200 kW bowthruster. These systems are fed and controlled by Bakker Sliedrecht’s direct water-cooled compact frequency drives. The vessels have a DP 2/3 Kongsberg installation, which will be supplied and implemented by the Combination Croon Bakker.
