Reviews a ship's propulsion system using an electromagnetic gear, developed in 1973 by Kawasaki Heavy Industries Ltd., Kobe, which was the subject of a paper presented at the International Symposium of Marine Engineering in Tokyo at that time. Perhaps it is worthy of renewed consideration in the present climate of shipping, when capital cost and operational efficiency have assumed greater than ever proportions. The novel feature of this design is the use of electromagnetic principles to effect speed reduction between prime mover and propeller, dispensing altogether with mechanical reduction gears. In developing this system, the designers have considered the following prime requirements of a ship's propulsion system: (i) Sturdiness and reliability. (ii) A high degree of maneuverability. (iii) Relatively low capital cost. (iv) Economical operating cost. (v) Compactness of engine room arrangement. (vi) Potential for volume manufacture. The idea of using an electromagnetic gear to ensure these properties was conceived a few years ago; it has now been brought to the stage of shore tests on a 16,000 hp prototype, driven by a 14,000 hp 430 rev/min Kawasaki-MAN V14V52/55 4-cycle diesel engine using water braking. Results have warranted the belief that the gear can be successfully applied to many types of ship in the future.
