Rolls-Royce has unveiled the latest addition to its range of marine thrusters, with the launch of new permanent magnet Azimuth Thrusters powered by permanent magnet (PM) technology. Launched at the Nor-Shipping maritime exhibition in Oslo, the new thruster is the Group’s latest development of PM technology, which already includes tunnel thrusters and a newly developed winch.
The launch follows a programme of sea trials in which a pair of permanent magnet azimuth thrusters demonstrated efficiency savings of 7-13% depending on ship speed, and in comparison to azimuth thrusters powered by a conventional diesel-electric system. The trials took place on board the RV Gunnerus, the Norwegian University of Science and Technology’s (NTNU) research ship, based in Trondheim.
