The authors have developed a new stem named "SEA-Arrow" to improve the propulsive performance of medium-speed ships such as LPG carriers. Having no protrusion of the bulbous bow, the SEA-Arrow can reduce bow waves and thereby greatly increase the propulsive performance. LPG carriers are required to have box-shape tanks arranged to the fore part of the hull because of necessity for efficient arrangement of LPG tanks, as well as develop a higher ship speed than oil tankers and bulk carriers. And LPG carriers are restricted in their lengths due to limitation in the facilities of their loading/unloading ports. Under these restrictions, the authors have carried out R&D of LPG carriers' hull form, aiming at improving the propulsive performance by minimizing the bow waves. By adopting the SEA-Arrow, the authors could reduce the wave resistance to a half and achieve a 6-10% reduction in the required main engine horsepower. This paper describes the features of the SEA-Arrow and its performance based on the model test results.
