Overview
IEC 62613-1:2011 is an international standard that specifies the general requirements for plugs, socket-outlets, and ship couplers used in high-voltage shore connection systems (HVSC-Systems). These systems enable the safe and reliable connection of electrical power from shore facilities to ships while docked at ports. The standard covers accessories designed for three-phase electrical systems with neutral and earth connections, with rated currents up to 500 A and operating voltages not exceeding 12 kV at 50/60 Hz frequencies.
This standard targets accessories primarily used in harsh outdoor marine environments, including exposure to seawater and temperature ranges from -25 °C to +45 °C. It provides a foundation for ensuring compatibility, safety, and performance in delivering shore-supplied high-voltage power to vessels, supporting maritime efforts to reduce emissions by allowing ships to shut down onboard generators while anchored.
Key Topics
-
Scope of Application
IEC 62613-1 applies to high-voltage accessories incorporating three phases (3 poles and Earth) and a single neutral pole, with rated currents up to 500 A and voltages not exceeding 12 kV. These components are designed for ship-to-shore power delivery in demanding marine conditions.
-
Design and Construction Requirements
The standard outlines specifications for dimensions, marking, terminals, locking devices, interlocks, and protection against electric shock. It addresses materials’ resistance to ageing, corrosion, heat, fire, and mechanical stress to ensure durability and operational safety.
-
Electrical and Mechanical Performance
IEC 62613-1 defines tests for insulation resistance, dielectric strength, temperature rise, short-circuit current withstand, and mechanical strength to verify that the accessories meet rigorous safety and reliability standards suitable for maritime environments.
-
Environmental Considerations
Accessories compliant with this standard are intended for use in seawater atmospheres and must withstand wide temperature variations, humidity, corrosion, and mechanical impacts encountered in port conditions.
-
Compatibility with HVSC Systems
This standard supports the IEC/PAS 60092-510 High Voltage Shore Connection Systems framework, ensuring that compliant accessories facilitate seamless ship-to-shore power interface, enabling standardization across ports and vessels worldwide.
Applications
-
Ship-to-Shore Power Supply
Enables vessels to connect to onshore high-voltage electrical power safely, allowing ships to switch off polluting diesel generators while docked, reducing emissions and noise pollution.
-
Marine Ports and Harbors
Equip ports with standardized shore power infrastructure compatible with ships adhering to IEC 62613-1 to ensure interoperability and efficient power delivery.
-
Shipbuilding and Retrofit
Assists manufacturers and ship operators in selecting or retrofitting ship electrical systems with plugs, connectors, and couplers compliant with international standards for high-voltage shore connections.
-
Electrical Accessory Manufacturers
Guides producers of plugs, socket-outlets, and couplers in designing products that meet international safety, mechanical, and environmental criteria for marine high-voltage power systems.
