The IEC 80005 standards
As the global trends and directives push toward decarbonization and cleaner air, Onshore Power Supply (OPS) is becoming a key technology. OPS allows ships to shut down their auxiliary engines while docked, allowing them to plug into shore-based supply. Thus, significant reductions in noise and emissions are made. Consequently, improving air quality around ports.However, connecting a vessel to a land-based grid is not so simple. High voltage, different ship configurations, and strict safety requirements require a unified approach. That is where the IEC 80005 standards come into play.

What Are the IEC 80005 Standards?
This Standard Series defines the international framework for Onshore Power Supply systems. This series is composed of three major parts:
IEC 80005-1: High Voltage Shore Connection (HVSC)
- Covers ships with electrical systems above 1kV.
- Defines standard connection interfaces between ship and shore.
- Specifies safety, control, and communication protocols.
- Ensures interoperability between ships and ports globally.
IEC 80005-3: Low Voltage Shore Connection (LVSC)
- Applies to vessels using electrical systems below 1kV.
- Used mostly by smaller ships like ferries or inland vessels.
- Focuses on plug types, safety interlocks, and protection measures.
IEC 80005-2: Shore Supply to Ships – Data Interfaces
- Covers communication between ship and shore.
- Enables safe power transfer via control signals, status updates, and fault monitoring.
- Supports both high and low-voltage systems.
IEC 8005 Series importance
These series:
- Supports global standardization, avoiding the need for custom setups
- Improves safety for both shore personnel and ship crew.
- Enhances compatibility, allowing ports to serve more types of vessels.
- Reduces costs for shipowners by enabling predictable OPS integration.
OPS & Compliance
Ports and shipbuilders are increasingly referring to the IEC 80005 series when designing infrastructure. Here is a hypothetical example of how it would look like:
- EU ports often require OPS readiness for new terminals.
- Some Asian ports (e.g., in Korea and China) are using IEC 80005-1 as the design reference for HVSC.
