Electrical installations in ships - Part 501: Special features - Electric propulsion plant

IEC 60092-501:2013(E) specifies requirements for all electric propulsion plants and gives the specifications, system design, installation and testing of at least:
 - generators and their prime movers;
 - switchboards;
 - transformers/reactors;
 - semiconductor convertors;
 - propulsion motors;
 - excitation systems;
 - control, monitoring and safety systems;
 - wires, cables, busbars, trunking systems;
 - harmonic filters.
 Bow and stern thrusters intended as auxiliary steering devices, booster and take-home devices, all auxiliary generating plants, and accumulator battery powered propulsion machinery and equipment are excluded. This fifth edition cancels and replaces the fourth edition published in 2007. It constitutes a technical revision. This edition included the following significant technical changes with respect to the previous edition:
 a) requirements regarding system responsibility, electromagnetic compatibility (EMC), harmonic distortion and filtering, special requirements for ships with propulsion motor(s) and podded drives, and power management system (PMS);
 b) overall technical review to update the standard according to general requirements and referenced equipment standards.
