Cold Ironing for Commercial Vessels

Rotary Frequency Selection  

Implementation of Cold Ironing on Commercial Vessels

Implementation of Cold Ironing on Commercial Vessels is a considerable capital investment. Cold Ironing does provide large emission reductions and is cost effective for ships that spend a lot of time at the port, or visits are frequent. Container ships, passenger ships, and reefers fall in the above category. The container ships and passenger ships account for 56 percent of all ships visits to the United States and both are growing dramatically. These vessels has the biggest impact of reducing emissions by using cold ironing.

The draft Emission Reduction Plan for Ports and International Goods Movement
in California recommended goals for emissions reductions from the hotelling of
ships using cold ironing to be 80 percent by 2020. NOx emissions would be reduced by 41 tons per day. Between 2008 and 2020, cold ironing could reduce emission by 100,000 tons using this technology.

Implementation of Cold Ironing on Commerical Vessels is a Considerable Capital Investment.

Challenges That Must Be Addressed before Implementation of Cold Ironing on Commercial Vessels.

Vessel Voltage Requirements- Ports have vessels coming in from around the world. These vessels' electrical power and voltage requirements vary between the type of ship and the country that manufacture the ship. A economical solution is a  TEMCo Cold Ironing Electric Power Converter. These converters converts frequency, voltage and phase. These power converter can convert 50Hz, 60Hz, or 400Hz to run the vessels equipment while docking. Deciding where to put the converter on the wharf or on a ship is a challenge in the implementation of cold ironing on commercial vessels.

Location of Converter - A cold ironing electric power converter can be added to either one, a wharf or a ship if enough space is available. New ship designs could include extra space for these converters and many older one can be retrofit to accommodate a cold ironing converter.  The NYK Atlas container ship, the new S-10 class Evergreen container ships, the new Alaska-class tanker, and the Diamond and Sapphire Princess passenger ships were all built with the equipment to connect to shore power. The four original Princess Cruise Line ships that cold-iron in Juneau, Alaska, were retrofitted with shore-power capabilities while en route to Alaska. Although Princess Cruise Line was able to retrofit its ships while in service, this  may not be the case for other types of ships.


Cold Ironing Converters offers a solution for different voltages and frequencies when implementing cold ironing on commerical vessels.

Storage and space seem to be the main concern when implementing cold ironing on commercial vessels. As with converters, cables used for cold ironing must be stored, when ships are not connected to shore power. Having enough space on a dock or on a ship for this equipment is an issue. The number of cables used to deliver power to ships at current cold-ironing installations varies, as does the actual connection of the cables to a ship’s electrical panel. Ports and shipping companies are looking at the feasible to standardizing the number of power cables and the actual electrical connection to ships. Because Princess Cruise Line is already cold-ironing at two ports on the West Coast, perhaps its connection system will become the standard for that industry.


Cables and storage are the main issues in implementing cold ironing on commerical vessels.
