Abstract (english)
One of the essential conditions for the sustainable development of maritime transport is the increase of energy efficiency, which contributes not only to economic efficiency but also to the reduction of pollutant emissions. Reduction of pollutant emissions can be achieved by adjusting the combustion process in the engine cylinder, after-treatment of exhaust gases, use of alternative fuels or reduction of sailing speed. Reduction of sailing speed is widely used in container ships, as it does not require additional investment and, if applied reasonably, has a positive effect on reducing fuel consumption and pollutant emissions. However, it leads to an increase in sailing time, and a greater reduction in sailing speed leads to a reduction in main engine efficiency and a reduction in the energy potential of the waste heat. In this paper, the effects of reducing the sailing speed on the efficiency and energy potential of the waste heat of a low-speed marine engine are investigated. The waste heat from the exhaust gases and the engine cooling system is used to generate steam and electricity and for desalination. In the examples studied, a 30.4% reduction in sailing speed from the planned speed results in a 53.1% reduction in fuel consumption and a 43.8% increase in sailing time. When determining the optimal sailing speed, it is also important to consider the specific fuel consumption data, which shows that an engine load of 60% to 80% is optimal for efficiency. Data from the manufacturer WinGD on fuel consumption and available waste heat for various engine loads as a function of the container ship’s sailing speed were used for the study.
