INNOVATIVE TECHNOLOGY OF REACTIVE ENERGY COMPENSATION FOR IMPROVING SHIP'S EEDI
Ключові слова:Energy Efficiency Design Index (EEDI), innovative energy saving technologies, power factor correction
Global warming, caused mainly by greenhouse gas emissions, prompted the world community to sign the Kyoto Protocol in 1997. The regulation of greenhouse gas emissions and related economic activities have ceased to be the prerogative of national authorities and become the subject of international agreements. Due to the largest air pollutants from the world's oceans are ships, the International Maritime Organization (IMO) adopted in 2003 Resolution А.962 (23): "IMO Policy and Practice on Reducing Greenhouse Gas Emissions from Ships", and determined that it is possible to achieve significant reductions in greenhouse gas emissions from ships through the adoption of technical and operational measures. This suggests that ships need to be more energy efficient, operating conditions are well thought out, and a clear methodology for assessing ships in terms of greenhouse gas emissions. The estimated energy efficiency factor of the vessel is the Energy Efficiency Design Index (EEDI), which is calculated according to a formula developed by IMO with the possibility of improving it through innovative energy efficient technologies. Since the entry into force of the IMO resolution, mainly work is underway to improve the EEDI based on existing innovative technologies in various categories. Progress does not stand still, but the list of new innovative technologies for energy efficiency categories has not expanded.
The presented article is devoted to the development of innovative technology of category C, to improve the energy efficiency index of the ship structure. This technology can used on its own, as well as an additional tool to extend the capabilities of existing energy efficiency technologies. In addition, the innovative technology for reactive energy compensation allows improving the EEDI and environmental performance of already operating vessels, through their simple modernization during planned repairs.
