Utility connections in port – Part 3: Low Voltage Shore Connection (LVSC) Systems – General requirements - Edition 1.0
 N PAS 80005-3

Annotation

This PAS describes low voltage shore connection (LVSC) systems, on board the ship and on shore, to supply the ship with electrical power from shore.

This PAS is applicable to the design, installation and testing of LVSC systems and addresses:

- LV shore distribution systems;

- shore-to-ship connection and interface equipment;

- transformers/reactors;

- semiconductor/rotating convertors;

- ship distribution systems; and

- control, monitoring, interlocking and power management systems.

NOTE It does not apply to the electrical power supply during docking periods, e.g. dry docking and other out-ofservice maintenance and repair.

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

It is expected that LVSC systems will have practicable applications for ships requiring up to 1 MVA. Low-voltage shore connection systems not exceeding 250 A, with a maximum of 125 A per cable and not exceeding 300 V to earth are not covered by this PAS. High-voltage shore connection systems are covered by IEC/ISO/IEEE 80005-1.
