Overview
IEC 62613-2:2016 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies dimensional compatibility and interchangeability requirements for accessories used in high-voltage shore connection systems (HVSC-systems) for ships. This second part complements the general requirements set out in IEC 62613-1 and covers accessories including plugs, socket-outlets, ship connectors, and ship inlets designed for use with voltages up to 12 kV, currents up to 500 A, and frequencies of 50/60 Hz.
These accessories incorporate up to seven pilot or auxiliary contacts and are intended for various ship types. The standard ensures that components from different manufacturers remain compatible and interchangeable, promoting safer and more efficient shore-to-ship power connections.
Key Topics
-
Dimensional Compatibility: The standard defines precise dimensional criteria to guarantee that plugs, socket-outlets, and ship couplers fit correctly to facilitate secure and reliable electrical connections.
-
Interchangeability: IEC 62613-2 emphasizes interchangeability among accessories, allowing equipment from diverse manufacturers or suppliers to be used without performance or safety compromise.
-
Technical Updates: The 2016 edition introduces additional configurations such as:
- Configuration I: 7.2 kV, 350 A three-phase accessories with three IP0 pilot contacts.
- Configuration J: 12 kV, 500 A three-phase accessories with seven pilot contacts.
-
Safety Features: Requirements include protection against electric shock, provision for earthing, locking devices, interlocks, and resistance to environmental factors such as corrosion, heat, and fire.
-
Testing and Construction: The standard prescribes testing methods for insulation resistance, dielectric withstand, partial discharge, temperature rise, mechanical strength, and electromagnetic compatibility to ensure durability and operational safety.
-
Standard Sheets: Annexes provide detailed drawings and dimensions for multiple accessory types and configurations, facilitating reference for manufacturers and users.
Applications
IEC 62613-2:2016 plays a critical role in the maritime and electrical engineering industries by enabling high-voltage shore connection systems that:
-
Enhance Ship Safety: By standardizing dimensional and functional requirements, the standard reduces hazards associated with incorrect or incompatible shore connections.
-
Improve Port Infrastructure: Ports and shipyards can implement HVSC systems confidently, knowing the shore-side components will accommodate various ship connectors.
-
Support Environmental Goals: The use of HVSC reduces emissions by allowing ships to shut down onboard generators and connect to shore power while docked.
-
Facilitate Global Shipping: The standard ensures global interoperability of shore connection accessories, supporting international shipping operations and compliance.
-
Guide Product Development: Manufacturers use the standard to design and produce plugs, sockets, and couplers that meet international quality and safety benchmarks.
