Benefits of Cold Ironing


Rotary Frequency Selection
Some of the Benefits of using Cold Ironing

The Benefits of using Cold Ironing technology it provides the fastest way to eliminate the pollutants that ports produced while ships are in port. Cold-ironing or sometime known as shorepower or alternative marine power, is where ocean-going vessels plug into the port electric grid while in port ("hotelling") rather than relying upon diesel auxiliary engines for power. Cold-Ironing has  been used for years by the U.S. Navy during docking, and recently cruise ships in Alaska has switched to cold ironing.

The Port of Los Angeles in 2005 did a study comparing using low sulfur marine fuel and Cold Ironing. Using lower sulfur fuel emission significant reduces the SO2 and PM but had marginal affects of NOx reduction. The Benefits of Cold Ironing is that all three air pollutants, Nox, SO2 and PM are significantly reduced.

Ports are looking at the Benefits of Cold Ironing

The Benefits of Cold Ironing is while ships are plugged in to port power, they would produce zero emissions. A example of this is when a single containership is  in port, it would eliminate more than 1,000 pounds of exhaust pollutants. In April of 2006, CARB identified Cold Ironing as a strategy to reduce emissions.  The timetable is to reduce emissions by 20 percent by 2010, 60 percent reductions by 2015 and 80 percent reductions by 2020. Many groups do not feel this is nearly aggressive enough for California to meet its clean air goal. It is estimated that cold ironing could eliminate over 454 kg of nitrogen oxides emissions, 32 kg of sulfur oxides and 7 kg of particulate matter in a single 24 hour port call for a typical container ship.

Health Benefits of Using Cold Ironing

The Benefits of using Cold Ironing for health issues has become an major concern in  ports, such as California and Seattle, both of these ports have set up programs using cold ironing to help with the health impact that air pollutions has cause from trade and goods movements. These pollutants can cause respiratory problems, cardiovascular issues, asthma and other respiratory symptoms. In California alone, they estimated that the statewide deaths that can be associated with these pollutants is around 9,000.

70 percent of cancer risk in California is cause by the toxic air contaminants in diesel PM.  The largest contributors to these toxic air contaminants were cargo handling equipment and ships using diesel engines at dock while at port. Exposure to diesel PM can also be linked to premature death and a number of heart and lung diseases.

In April of 2006, The Port of Seattle and the Port of Los Angeles received the annual Clean Air Excellence Awards. This award is given to honor and recognizes outstanding, and innovative efforts to help make our environment cleaner. Both of these ports are using and implementing the Cold Iron Technology. The draw-backs on the implementation of cold iron is the expenditure for the ports and ships, with little cost saving. Many of the reports we see on the cost of implementing cold ironing was done in the early 2000, With the raising cost of diesel fuel, cold ironing is becoming more feasible. Another factor that will help speed up ports using cold ironing, is in aspect to global warming, and  what fossil fuel is doing to our planet.

One of the Benefits of Cold Ironing is keeping our enviroment clean.

As Cold Ironing becomes global, and each port will have different frequencies and voltages, a Cold Ironing Electric Power Converter will become an economical solution. TEMCo Cold Ironing Electric Power Converter is a unique converter that performs multiple functions. With these converters you can connect to any shore power in the world, ranging from 25 kVA to over 400 kVA. These Cold Ironing Converters also stabilizes and offers power factor correction.  

California and Seattle Ports are seeing the benefits of Cold Ironing.
