Copper Helps Curb Pollution in Ports

Edition #98: Winter 2004

Copper is playing a key role in helping ship owners avoid adding to air pollution in ports of call. To meet this environmental concern, owners are spending millions to enable their ships to purchase power from local utilities via heavy copper cables and added substations, instead of operating their shipboard generators. These efforts are known as "cold ironing."

It takes four heavy copper cables (black) like these to deliver enough power from a shore-based substation to a Princess cruise liner in Juneau. The thinner black cable is for communications. To avoid any contributions to air pollution while in port, the liners don’t operate their boilers or electrical generators.
