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.
