IEC/IEEE 80005-3:2025

Description

This document specifies provisions for the design, installation and testing of low-voltage shore connection (LVSC) systems, onboard ships and on shore, to supply the ship with electrical power from shore.

This document is applicable to:

–            ships requiring up to 1 MVA while at berth;

–            three-phase shore connection systems rated 250 A and above, and with a nominal voltage rating of 400 V AC to 1 000 V AC;

–            shore-side connection systems;

–            shore-to-ship connection and interface equipment;

–            transformers and reactors;

–            semiconductor and rotating frequency convertors;

–            ship-side connection systems;

–            protection, control, monitoring, interlocking and power management systems.

This document does not apply to:

–            inland navigation vessels;

–            high-voltage shore connection systems, including ships built in accordance with the annexes of IEC/IEEE 80005-1;

–            the electrical power supply during docking periods, for example dry docking and other out-of-service maintenance and repair;

–            systems to be operated by ordinary persons as defined in 3.19.

NOTE 1 Other standards are available specifically for inland navigation vessels in Europe.

NOTE 2 IEC 60092-507 is applicable to small vessels.

NOTE 3 Additional or alternative requirements can be imposed by national administrations or the authorities within whose jurisdiction the ship is intended to operate and by the owners or authorities responsible for a shore power supply or distribution system.

NOTE 4 High-voltage shore connection systems are covered by IEC/IEEE 80005-1.

NOTE 5 Some existing 380 V AC ship systems can be supplied by 400 V AC.
