Abstract

The climatic change constitutes an important problem of world scale that its negative consequences appear in our days. The gases of greenhouse, as dioxide of coal CO2 and ozone O3 that they are emitted by the ships, contribute negatively to the phenomenon of greenhouse. Moreover, the atmospheric pollutants like the SO2 oxides NOx, particulate matters (PM), and volatile organic compounds VOCS, have a negative impact on the environment, as well as on people’s health. Regulations, that are continuously modified, have been established for the reduction of ships’ emissions, in the Annex VI of MARPOL 73/78, as well as various directives and regulations by the European Union. However, apart from the regulations, there are also certain technologies and methods that contribute in the reduction of emissions from the ships. Ιn 2010, natural gas covered the 24% of the global energy market. .More than 30% of world trade is transported by sea , in the form LNG. Natural gas is a sustainable solution for reducing emissions. LNG is a form of NG easily and economically transported and helps fight climate by reducing the pollutants emitted during the combustion of other fossil fuels. Τhe creation of more and more storage and regasification terminals has resulted in a larger movement of LNG cargo and an evolution of the fleet of LNG. The international maritime community, therefore, following the new data, significantly increased both the size and capacity of the LNG Carrier (Q-FLEX, Q-MAX).
