For the second time this year, the United States Environmental Protection Agency (EPA), with the support of Hamburg S'd, has been able to generate important data on possible contaminant reductions in marine shipping.

In late August 2010, Low Sulphur Marine Gas Oil (LSMGO), a fuel with a sulphur content of 0.1 per cent, was used on the container ship 'Cap San Lorenzo' ' deployed in the service between US Gulf and Caribbean/South America East Coast 'while the vessel was entering and departing the port of Santos. According to the EPA, it was the first test of this kind to take place in Santos.

The use of LSMGO had previously been tested on the 'Cap San Lorenzo' in April 2010 in the ports of Veracruz, Altamira and Houston, in the Gulf of Mexico.

"We recognize and applaud the efforts of fleet owners, such as Hamburg S'd, who voluntarily engage in emissions reduction strategies like fuel switching,' said Gina McCarthy, U.S. EPA's Assistant Administrator for Air and Radiation. 'EPA estimates that a ship can achieve a 95% reduction in sulphur dioxides and an 85% reduction in fine particulates when lower sulphur fuels are used. '

A number of areas with tighter sulphur limits, known as Emission Control Areas (ECAs), have now been bindingly defined. Since January 2010, for example, the fuels used at berths within the European Union have been allowed to contain no more than 0.1 per cent sulphur. As of August 2012, only fuel with a sulphur content of 1.0 per cent will be permitted on the North American Atlantic and Pacific Coast, as well as the US Gulf Coast.

'We are glad that this fuel switching project will yield emissions data to show U.S., Mexican and Brazilian policy makers that real reductions can be achieved by burning lower-sulphur fuels near their coastlines," observes Michelle DePass, U.S. EPA's Assistant Administrator for International and Tribal Affairs, underlining the significance of the tests. Along with Hamburg S'd, these tests were also supported by the U.S. Maritime Administration, the Mexican environmental agency Secretar'a de Medio Ambiente y Recursos Naturales (SERMANAT), as well as the ports of Houston, Veracruz, Altamira and Progreso.

'We didn't have to think long about supporting the EPA's trials,' commented Dr Ottmar Gast, Chairman of the Executive Board of Hamburg S'd. 'Because the fact is that protection of the environment and natural resources is an integral part of each entrepreneurial and organisational decision we take. Environmental protection is only rarely linked to major advances brought about by technological revolutions. Rather, it is the sum of many small measures which result in improvements. And that is precisely what we wish to achieve with the tests in our trade.'
