AN OVERVIEW OF MEASURES FOR SHIP’S ENERGY EFFICIENCY IMPROVEMENT

The current state of ship energy efficiency measures which are being taken to improve ship efficiency, reduce fuel consumption and lower emissions is presented. Regarding design and construction of a new vessel, the optimization of the hull, appendages, and propulsion systems is discussed. Furthermore, devices that are used to improve the efficiency of propellers are introduced, together with a survey of developing technologies aimed at reducing the hull frictional resistance or using renewable energy sources. Finally, regarding fuel efficiency in service, some operational and maintenance measures that can reduce fuel consumption are addressed. Some of the named approaches can be successfully applied to already existing vessels to improve the current performances.
