Novas tecnologias para prevenção da poluição no meio ambiente marítimo

Abstract

Navigation isanessentialactivityforthe sustainability and development of the society. For many years it has performed a very important function, connectingterritories and people, exploring resources, carryingcargo and people. With such responsibility and the need for ever-increasing improvement of their means of transport, there was a demand for energy efficient vessels, without concerns to its consequences. Today, however, theworld has changed that thoughtand started to worryabout the pollutionpreventionof the maritime environment. Energy efficiency can no longer overlap the care needed to prevent pollution and a number of requirements must be followed by those who use water resources. Because ofthis reason, several technologies are designed to prevent or lessen the chances of accidents involving maritime pollution, especially when related to merchant activity. This work will exhibitnew technologies to reduce emissions of certain pollutants traditionally issued, using environmentally friendly alternative fuels and equipment to control situations with risk of pollution. Unfortunately solar energy and wind work as an energy source complementary to the traditional, onmerchant vessels, because of thelack of technologyto meet all the needs of a ship. It is emphasized that these alternatives for the prevention ofthepollution are mere suggestions and it is up to those involved in maritime activity taking care of natural resources, increasingly scarce and atthe same time, fundamental for the whole world population, noting the use of any advance and equipment that can be employed in that order.
