Abstract

The environmental regulations for CO2 emissions from the ship have been established recently, and fuel oil price has been increased continuously. In order to overcome these circumstances, Energy Saving Devices (ESDs) have been developed continuously to reduce the fuel oil consumption and improve the propulsive efficiency. This paper 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.

최근에 CO2 배출에 대한 환경 규제가 마련되었고, 연료유 가격은 계속해서 상승하고 있다. 이런 상황들을 극복하기 위해 연료소모량을 감소시키고 추진효율을 개선한 에너지 저감 추진장치들이 계속해서 개발되고 있다. 본 논문에는 핸디형 산적화물선에 적용한 PBCF, SCHNEEKLUTH duct, 비대칭 러더 벌브, Mewis duct의 성능 실험을 서술하였다. 그 결과, SCHNEEKLUTH duct가 다른 에너지 저감 장치들에 비해 연료소모량 절감과 추진효율의 향상 측면에서 더 효과적이었다. 또한 SCHNEEKLUTH duct가 거주구 진동에도 효과가 있음을 확인하였다. 그리고 연료소모량은 주기관 de-rating을 통해서도 절감할 수 있었다.
