Should industrial sectors prioritize automated safety technologies over traditional manual labor practices?
French company NG3 has debuted its Flying Plug system, a mechanized shore-power solution designed to connect tankers to terminal grids. The system is rated for 11 kV and 700 A, allowing vessels to utilize shore power with minimal manual intervention.
Why it matters
The system removes the need for crews to handle high-voltage connectors manually, which improves safety and increases the time a tanker can remain plugged in during its typical 10-hour port stay. By separating power operations from cargo handling, the technology helps tankers maintain grid connections more efficiently.
The Flying Plug system operates at 11 kV and 700 A, requiring a standard 20 ft container footprint for installation. NG3 estimates the automated connection process takes 15 minutes to complete after mooring.
The players
NG3
This French company specializes in the development of mechanized power connection systems for maritime and industrial applications.
Rotterdam Shore Power
This entity oversees infrastructure development and secured a 90 million euro loan from the European Investment Bank to support sustainable port operations.
European Investment Bank
This is the lending arm of the European Union that provides financing for projects that support EU policy goals, including environmental sustainability.
The details
A ropeway system extends from the terminal to the vessel's aft end, where a shipboard hoisting system lifts the connector into place. The unit requires only one crew member and one terminal operator to manage the procedure.
Timeline
NG3 began deploying its PLUG technology in 2011.
The OCIMF published shore power guidance in June 2025.
Rotterdam Shore Power secured a major bank loan in 2026.
Roadmap
The introduction of automated connection systems reflects the maritime industry's shift toward electrification and the automation of port-side infrastructure. As ports modernize, these mechanical solutions aim to replace legacy manual processes to meet stricter environmental mandates.
Tanker operators can expect reduced downtime and improved safety margins during port calls through the use of automated power connections. These systems facilitate the adoption of shore-power mandates by streamlining the interface between the vessel and the local terminal infrastructure.
The takeaway
Automating the connection process allows for more consistent shore-power usage during standard tanker port stays. Companies looking to implement such systems should prioritize infrastructure that aligns with the 20 ft container standard to ensure compatibility with existing terminal footprints.
