A ship's motions (surging, heaving, swaying, pitching, rolling, yawing) and her fuel consumption were measured while sailing on her 12 different courses in the same maritime and meteorological conditions. The author made an analysis and has got the following results: Based on the data of the ship's motios measured, some power spectra and the variances of the amplitude of motions were obtained ; those results are illustrated in Fig.2-7 (using circle graphs). As an index value of the ship's motion, an integrated value of modified power spectra was used, and the correlation matrix between fuel consumption and index values of the ship's motions are shown in Table 2. Fig.8 shows the relation between fuel consumption and the ship's courses. The relation between fuel consumption and the index values of surging, heaving and pitching are shown in Fig.9-11. The correlation between fuel consumption and surging is stronger than that of fuel consumption and the other factors.
