Scope

IEC 60092-501:2025 applies to electric propulsion plants and specifies system design, installation and testing for equipment such as:
- generators and their prime movers or other power sources (fuel cell, battery, …);
- switchboards;
-transformers/reactors;
- semiconductor converters;
- propulsion motors;
- excitation systems;
- control, monitoring and safety systems;
- wires, cables, busbars or trunking systems;
- podded drives including azimuth.
Thrusters intended either as auxiliary steering or auxiliary propulsion devices or both and booster equipment are excluded.
This sixth edition cancels and replaces the fifth edition published in 2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of podded drives including azimuth in the scope;
b) addition of alternative power sources;
c) modification of the special requirements for ships with only one propulsion motor;
d) new definition for test of slip ring units;
e) modification of Figure 2 and description;
f) addition of a description of power management functions;
g) addition of emergency stop at control stations;
h) clearer start blockings;
i) deletion of Table A.2, Table A.3 and Table A.4 in Annex A. Their content has been moved to Table 1.
