Overview
IEC/PAS 80005-3:2014 - Utility connections in port: Part 3 - Low Voltage Shore Connection (LVSC) Systems - General requirements is a pre-standard published by the International Electrotechnical Commission (IEC). It defines general requirements for design, installation and testing of low-voltage shore connection (LVSC) systems used to supply ships with electrical power from shore (shore power). The PAS covers both shipboard and shore-side equipment and is applicable for practical LVSC applications up to about 1 MVA. It excludes high-voltage shore connections (covered by IEC/ISO/IEEE 80005-1) and certain small LV systems (≤ 250 A, ≤ 125 A per cable and ≤ 300 V to earth), and does not apply to out-of-service scenarios such as dry docking.
Key Topics
The standard addresses technical and safety aspects essential for reliable shore-to-ship power transfer:
- System scope: LV shore distribution, ship distribution, shore-to-ship interface equipment.
- Electrical components: transformers/reactors, semiconductor and rotating converters, circuit-breakers, disconnectors, neutral earthing resistors.
- Connectors and cabling: ship-to-shore connection cables, plugs, socket-outlets, pilot and earth contacts, cable management and monitoring (tension and length).
- Protection & safety: short-circuit and earth-fault protection, equipotential bonding, personnel safety, protection against moisture/condensation, hazardous-area considerations.
- Control & power management: control, monitoring, interlocking, emergency shutdown, load transfer strategies (blackout transfer and automatic synchronization).
- Verification: initial testing, tests at first call and repeated calls, periodic maintenance and documentation requirements.
- Special provisions: annexes with additional requirements for specific ship types (e.g., offshore, container ships, tankers) and normative details for cables and connectors.
Applications
IEC/PAS 80005-3 is practical for:
- Port authorities and shore power infrastructure planners implementing LV supply points.
- Shipowners, ship designers and naval architects specifying LVSC interfaces and onboard receiving switchboards.
- Electrical engineers, integrators and contractors installing shore-to-ship cable reels, plugs, monitoring and protection equipment.
- Classification societies, regulators and operators seeking consistent safety, interoperability and testing procedures.
Practical benefits include safer, interoperable shore connections, reduced vessel emissions while berthed, and standardized procedures for commissioning and maintenance.
