Global Marine Fuel Trends 2030

Global Marine Fuel Trends 2030 central objective is to unravel the landscape of fuels used by commercial shipping over the next 16 years. The problem has many dimensions: a fuel needs to be available, cost-effective, compatible with existing and future technology and compliant with current and future environmental requirements. In a way, one cannot evaluate the future of marine fuels without evaluating the future of the marine industry. And the future of the marine industry itself is irrevocably linked with the global economic, social and political landscape to 2030

Future Outlook of Artificial Cavity Application for Reducing Hydrodynamic Resistance of Containerships

4siAbsolute commitment to reduce the impact of greenhouse gas emissions while increasing fuel efficiency and power density requires further enhancement of prime mover characteristics and special coatings, but mostly requires compliance with EEDI (energy efficiency design index) measures. For the container shipping industry this represents significant increases in fuel costs that can be mitigated above all by reduction of power demand, that is, of ship frictional resistance. In this respect, this paper discusses advantages attainable by application of the ACS (air cavity system) technology on the basis of recent KSRC (Krylov State Research Centre) studies. Savings in operating costs yielded by the enhanced propulsion performance for ships fitted with this system are illustrated by a case study of a containership.openopenTrincas, Giorgio; Borusevich, Valery; Poustoshny, Alexander; Sverchkov, AndreyTrincas, Giorgio; Borusevich, Valery; Poustoshny, Alexander; Sverchkov, Andre
