Abstract

In the previous paper, the authors showed a New Stem named SEA-Arrow to improve the propulsive performance of medium-speed ships such as LPG carriers. Having no protrusion of bulb, the SEA-Arrow can reduce the bow waves and greatly increase the propulsive performance in the design condition. In order to evaluate the propulsive performance of the SEA-Arrow, the voyage data analysis of the SEA-Arrow and the conventional hull form ship was carried out. This paper describes the comparison of the propulsive performance of the SEA-Arrow and the conventional hull form ship based on the voyage data analysis.
