摘要

This paper presents a method to normalise the shaft power data recorded at high-frequency to derive the baseline (calm water power) curves by applying a shaft power correction. This is carried out using two correction methods for added power due to waves developed for sea-trial measurements - namely, STAWAVE-1 and STAWAVE-2. The calm water power is then obtained as a difference between the measured power and the added power. The results obtained using this normalisation method is compared to filtering techniques. It is shown that the differences between the predictions using the two methods are minimal, with a maximum of 6% at the normal operational speed of the vessel. The normalising method retains about 40 % of the total data, nearly 4 times more than the datasets retained with filtering methods.
