Outline of Final Research Achievements

The objective of this study is development of an energy-saving support system for ship operation. This study consists of two kinds of research work. One is the main engine power estimation based on discrete wavelet transform. The other is development of a model experiment procedure to construct the fuel-consumption data base. The system doesn’t require any additional hardware to the main engine, but can estimate the fuel-consumption based on the wave spectra estimated from ship motions and the data base constructed by the model experiment. It has been shown that the main engine power can be estimated by the multi-resolution analysis of the discrete wavelet transform. Moreover, it has also been clarified that the fuel-consumption database can be constructed using torque measurement system developed in this study. Overall, it can be recognized that the objectives of this study have been achieved, although accuracy improvement remained as a future task.
