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.
