ABS releases guide for design & operation of high voltage shore connections
Class Standards developed for High Voltage Systems The use of shoreside power, commonly called cold ironing, is becoming increasingly popular among ports and terminals seeking to reduce local air pollution emissions.While work to develop internationally-agreed standards for high voltage connections continues, leading class society ABS has released a Guide for High Voltage Shore Connection to address key safety concerns as well as design considerations for shipboard installations.Cold ironing will continue to grow in importance as more ports around the world install facilities to accommodate this alternative source of auxiliary power, says Yoshi Ozaki, ABS Director of Environmental Technology. The design criteria provided in this Guide will help to mitigate risk surrounding safety concerns related to the use of high voltage connections.Cold ironing is the practice of shutting down a vessels generators while in port and using shoreside power to supply electrical loads. The guidance from ABS fills the gap in the absence of universally adopted standards for high voltage connections. Current class Rules address low voltage shore connections which are typically 450V. The new ABS Guide addresses connections of 6.6 kV or 11 kV.Cold ironing using high voltage brings with it a variety of unique safety considerations. One of the ...
