Inland navigation vessels - Electrical shore connection, three phase current 400 V, 50 Hz, up to 125 A - Part 2: On-shore unit, additional requirements

This technical specification addresses specific requirements for shore-to-ship power connections designed for inland waterway vessels. It focuses on the electrical interface parameters, defining a three-phase system operating at 400 volts and 50 hertz, with a maximum current capacity of 125 amperes. The document serves as a supplementary section to an earlier framework, detailing additional constraints and guidelines necessary for safe and reliable power transfer between stationary land-based facilities and moving vessels navigating inland waterways. It outlines compatibility criteria for connecting equipment, ensuring that electrical systems on board vessels can interface correctly with shore power sources without compromising safety or performance. The content covers specific aspects of connection hardware, safety protocols for high-current transfer, and technical specifications required to minimize risks during the plugging and unplugging processes. By adhering to these guidelines, operators and manufacturers can facilitate the use of alternative power sources, reducing emissions and noise pollution in port and waterway environments. The document provides a standardized approach to implementing electrical infrastructure that supports the transition towards greener maritime operations while maintaining operational efficiency.
