scope:

This standard is applicable to electric propulsion machinery and plant and deals with the specifications, installation and testing of:

 - propulsion motors ;

 - propulsion generators and their prime movers ;

 - electrical couplings ;

 - associated semiconductor convertors ;

 - excitation systems ;

 - control monitoring, instrumentation and protection equipment and systems ; and

 - wires and cables.

Bow and stern thrusters intended as auxiliary steering devices, all auxiliary generating plants and accumulator battery powered propulsion machinery and equipment are excluded.

Note. - The requirements given in other clauses of IEC Publication 92: Electrical Installations in Ships, are also applicable to electric propulsion installations, unless otherwise mentioned in this standard. Requirements applicable to propulsion systems may also be applicable to other power consumers directly connected to the main electric propulsion system, the functioning of which may influence the propulsion or manoeuvrability of the ship.
