Keeping our Environment Clean Means Beautiful Beaches

Air pollution from trade and goods movements has become a major health concern. The emissions and associated health impacts are greatest in regions with major ports. California and Seattle, just to name a few ports, have set up programs to reduce air pollution in a number of different ways.

The health impact of these pollutants near large ports is a major concern.  These pollutants can cause premature deaths, respiratory problems, cardiovascular issues, asthma and other lower respiratory symptoms. Just in California alone, they estimated that the annual statewide deaths that can be associated with exposure to ozone and particulate pollution is around 9,000.

About 70 percent of the potential cancer risk from toxic air contaminants in California is due to diesel PM.  The largest contributors to cancer risk were cargo handling equipment and ships using diesel engines at dock while at call.  While ships in transit produce a substantial portion of total port-related diesel PM, they did not produce a comparable cancer risk because these emissions are released off-shore and dispersed over a very wide area.

Keeping our Environment Clean for Future Generations

When at port, ships' emissions of Nox and fine particulate matter (PM) also contribute to regional ozone and to local health risks. Repeated exposure to these emissions can make people more susceptible to respiratory infection and lung inflammation and can aggravate pre-existing respiratory diseases. Exposure to diesel PM can also be linked to premature death and a number of heart and lung diseases.

As set forth by the ARB Board on April 20, 2006, California's five specific goals for addressing the air pollution associated with goods movement are:

  • Reduce total statewide international and domestic goods movement
    emissions to the greatest extent possible and at least back to 2001 levels by year 2010.
  • Reduce the statewide diesel PM health risk from international and domestic goods movement by 85 percent by year 2020.
  • Reduce NOx emissions from international goods movement in the South Coast by 30 percent from projected year 2015 levels and 50 percent from projected year 2020 levels based on preliminary targets for attaining federal air quality standards.
  • Apply the emission reduction strategies for ports and goods movement statewide to aid all regions in attaining air quality standards.
  • Make every feasible effort to reduce localized risk in communities
    adjacent to goods movement facilities as expeditiously as possible.

Shore-side power or “cold ironing” has become an important part of reducing these air pollutions. While ships are plugged-in to shore-port-to-ship power, they would produce zero emissions. That would eliminate more than 1,000 pounds of exhaust pollutants in a single containership port call.  In April of 2006, CARB identified “cold ironing” as a strategy to reduce emissions with a goal of a 20 percent reduction by 2010, 60 percent reductions by 2015 and 60 percent reductions by 2020. This timeline is not nearly aggressive enough for California to meet its clean air goals.

Using cold ironing is not a new technology, the U.S. Navy has been using shore-side power for quite some time for their ships and nuclear submarines.  Large commercial shippers around the world are beginning to use cold-ironing, realizing that the technology is more cost efficient in the long run.

As this method becomes global, there will be an increase in the use of shore-port to-ship power converters.  Because each port will have different frequencies and voltages, a converter becomes an economical solution. A TEMCo Shore-Port-to-Ship Power Converter is a unique frequency converter that performs multiple functions. It provides the possibility to connect to any shore power connection anywhere in the world ranging from 25 kVA to over 400 kVA.  Supplying power is only half of what this converter does, it also stabilizes and offers power factor correction.
