산적화물선의 에너지 저감 장치들의 성능 비교에 관한 연구

Abstract

Recently, the environmental regulations have been developed in regards to CO2 emissions for the ship and fuel oil price has been increased continuously. In order to overcome these circumstances, the eco-design is to be applied to the ship. Accordingly, Energy Saving Devices(ESDs) have been developed continuously to reduce the fuel oil consumption and improve the propulsive efficiency.

This paper deals with several kinds of energy saving devices and how to achieve the fuel oil saving by selection of the main engine.

And this paper also describes the trial performance of PBCF(Propeller Boss Cap Fins), SCHNEEKLUTH duct, Asymmetric rudder bulb and Mewis duct applied to handy-size bulk carriers.

As a result, SCHNEEKLUTH duct is more effective than other energy saving devices at the reducing the fuel oil consumption and the improvement of the propulsive efficiency. In addition, it is confirmed that SCHNEEKLUTH duct is really effective in the vibration of the deck house. And the fuel oil consumption can also be reduced through main engine de-rating.

If SCHNEEKLUTH duct and main engine de-rating are properly combined for handy-size bulk carriers, it will be expected to reduce more fuel oil consumption and CO2 emissions.
