Ship At Port

In the last few years, many of our ports have come under great pressure to improve their emissions from diesel gas and other contaminates that pollute our air. The volume of global trade has been rising steadily in the past few years, and nearly 80 per cent of global trade is by sea.


While ports are seeing increased economical activity, countries around the world are grappling with the health effects of shipping-related pollution. Until recently, ocean-going vessels have been under few regulations, and most of them use the least expensive and dirtiest fuel available.


Health issues and global warming have proven that we need stronger regulations aimed at cutting shipping related emissions.  Most will agree that these new regulations are not strong enough, and most of the regulations are still not legally passed, enforced or monitored. The CARB Plan targets a 20 per cent reduction in diesel PM by 2010 from 2001 levels, which it claims will reduce health risks by 60 per cent or more by 2020. It is good to set goals; but as of yet, there is no reliable plan or strategy. We need to see commitments to specific details for mandatory emission reduction instead of voluntary incentives for industry.


One of the first regulatory steps CARB has required is for ships to use cleaner-burning fuels in their auxiliary diesel engines within a 24 nautical mile range of the California coastline.  The ship's use of cargo-handing equipment such as forklifts and cranes will result in replacing or retrofitting their engines. The new regulations, which went into effect on January 1, 2007 are expected to cut PM emissions by a total of 23,000 tons, NO emissions by 15,000 tons and SO emissions by 200,000 tons by the year 2020.

The U.S. EPA is working on reducing emissions from propulsion engines on oceangoing vessels. In 2003, the agency adopted emission standards for new Category Three Marine Diesel Engines installed on vessels registered in the U.S. from January 1, 2004 onward. The EPA also intends to set standards for fuels used by marine engines.  The Federal Agency estimates that with these new regulations, when fully implemented by the year 2030, will prevent up to 12,000 premature deaths, 15,000 heart attacks, and 6,000 child asthma-related emergency room visits throughout the United States.


Because issues such as engine emissions are an international issue, the IMO is also framing rules for cutting down shipping emissions. The rules include a global cap of 4.5 per cent by mass on sulfur content of fuel oil and recommends the monitoring of sulfur content globally.  The IMO is also encouraging countries to declare their coastlines as “SO Emission Control Areas,” where sulfur content in fuel must not exceed 1.5 per cent.

One of the fastest and most expensive ways to cut emission fuel altogether is to use shore-port-to-ship power, which  is called “Cold Ironing.”  This process requires ships plugging into onshore power.  Ships will have to be retrofitted for onshore power systems, and there would be an expense for updating their power systems.  Nearly 20 per cent of the ships visiting California ports will use shore-based power by 2010. This number would gradually go up to 80 per cent by 2020 according to CARB. The one drawback is that this process may not be economically viable for infrequent port visitors.


Ports all over the world are starting to offer terminals with shore-port-to-ship power, and cruise ships are now setting up all their vessels for shore power.  China has set up their large container ships to use shore power, and the Navy has used this method for years.  Shore-port-to-Ship power will be the wave of the future as nations around the world realize the need to protect our environment for future generations.


As this method becomes global, there will be an increase in the use of shore-port-to-ship converters.  Because each port will have different frequencies and voltages, converters become the 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.
