That’s what I read.
The R One is fitted with four Wärtsilä 12V32LNE diesel electric engines, each of which produces 4,860kW at 720rpm. They are resiliently mounted to reduce vibration and operate on heavy fuel oil.
Oil purifiers were supplied by Westfalia and oil/water separators by Sofrance. With a cruising speed of 18k, the ship has a maximum speed of 21k.
The vessel has two Cegelec variable frequency propulsion machines each with a double-winding synchronous motor of 6,750kW at 170rpm, two six-pulse synchrodrive convertors of 6,750kW and two propulsion transformers of 4,300kVA. GEC Alsthom supplied the four 4.6MW alternators, as well as the 750kW motors for the Brunvoll bow thrusters.
