Consideration regarding the reduction of pollutions emissions by increasing energy efficiency in ship operations

Abstract

The use of experimental investigation techniques in the research of internal combustion engines has contributed substantially to their progress and development over time. The performances obtained in the development of modern engines have been strongly influenced by the emergence and development of the investigation equipment, especially the laser and the modern computing technique. Maritime transport generates about 4% of the total CO2 emissions produced by human activities, which means that its carbon value is almost as large as that of Germany. Emissions from this sector are not yet internationally regulated, but this issue is currently being debated within the IMO and the United Nations Framework Convention on climate change (UNFCCC). Of the strategies to reduce pollutant emissions from ships, identified so far, the technical solutions are the first ones that have been implemented on board. The advantage of using technical solutions onboard ships is the high efficiency of reducing a product or several pollutant products, but the main disadvantage is the high cost of implementing and operating them on board ships.
