In view of the high fuel costs many shipowners have installed a main engine driven generator for the production of electricity on board. This generator profits from the cheap fuel which is used by the main engine. In general, a frequency converter is used to convert the varying frequency current, produced by the generator, into a three- phase alternating current with a constant mains frequency. Another way to produce a current with constant frequency, is by using the properties of the controllable pitch propeller. The controllable pitch propeller can maintain constant propeller revolutions despite varying ship's speed and external conditions. This system, however, is much less used because of the many disadvantages when sailing at reduced speed. This investigation, which compares a number of generator systems, shows that there are possibilities to improve the controllable pitch propeller-generator system in such a way that it can become equivalent, or even superior, to all usual generator systems.
